Abstract
The linear ubiquitin assembly complex (LUBAC) consists of HOIP, HOIL-1 and SHARPIN and is essential for proper immune responses. Individuals with HOIP and HOIL-1 deficiencies present with severe immunodeficiency, autoinflammation and glycogen storage disease. In mice, the loss of Sharpin leads to severe dermatitis due to excessive keratinocyte cell death. Here, we report two individuals with SHARPIN deficiency who manifest autoinflammatory symptoms but unexpectedly no dermatological problems. Fibroblasts and B cells from these individuals showed attenuated canonical NF-κB responses and a propensity for cell death mediated by TNF superfamily members. Both SHARPIN-deficient and HOIP-deficient individuals showed a substantial reduction of secondary lymphoid germinal center B cell development. Treatment of one SHARPIN-deficient individual with anti-TNF therapies led to complete clinical and transcriptomic resolution of autoinflammation. These findings underscore the critical function of the LUBAC as a gatekeeper for cell death-mediated immune dysregulation in humans.

Abstract
Skin inflammation is a complex process implicated in various dermatological disorders. The chronic proliferative dermatitis (cpd) phenotype driven by the cpd mutation (cpdm) in the Sharpin gene is characterized by dermal inflammation and epidermal abnormalities. Tumour necrosis factor (TNF) and caspase-8-driven cell death causes the pathogenesis of Sharpincpdm mice; however, the role of mind bomb 2 (MIB2), a pro-survival E3 ubiquitin ligase involved in TNF signaling, in skin inflammation remains unknown. Here, we demonstrate that MIB2 antagonizes inflammatory dermatitis in the context of the cpd mutation. Surprisingly, the role of MIB2 in limiting skin inflammation is independent of its known pro-survival function and E3 ligase activity. Instead, MIB2 enhances the production of wound-healing molecules, granulocyte colony-stimulating factor, and Eotaxin, within the skin. This discovery advances our comprehension of inflammatory cytokines and chemokines associated with cpdm pathogenesis and highlights the significance of MIB2 in inflammatory skin disease that is independent of its ability to regulate TNF-induced cell death.

Animal Model Exp Med 2023; 6:489-498. [PMID: 36097701 PMCID: PMC10614123 DOI: 10.1002/ame2.12265] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/11/2022] [Accepted: 05/24/2022] [Indexed: 11/09/2022] Open
Abstract
BACKGROUND SHARPIN (SHANK-associated RH domain interactor) is a component of the linear ubiquitination complex that regulates the NF-κB signaling pathway. To better understand the function of SHARPIN, we sought to establish a novel genetically engineered Syrian hamster with SHARPIN disruption using the CRISPR/Cas9 system. METHODS A single-guide ribonucleic acid targeting exon 1 of SHARPIN gene was designed and constructed. The zygotes generated by cytoplasmic injection of the Cas9/gRNA ribonucleoprotein were transferred into pseudopregnant hamsters. Neonatal mutants were identified by genotyping. SHARPIN protein expression was detected using Western blotting assay. Splenic, mesenteric lymph nodes (MLNs), and thymic weights were measured, and organ coefficients were calculated. Histopathological examination of the spleen, liver, lung, small intestine, and esophagus was performed independently by a pathologist. The expression of lymphocytic markers and cytokines was evaluated using reverse transcriptase-quantitative polymerase chain reaction. RESULTS All the offspring harbored germline-transmitted SHARPIN mutations. Compared with wild-type hamsters, SHARPIN protein was undetectable in SHARPIN-/- hamsters. Spleen enlargement and splenic coefficient elevation were spotted in SHARPIN-/- hamsters, with the descent of MLNs and thymuses. Further, eosinophil infiltration and structural alteration in spleens, livers, lungs, small intestines, and esophagi were obvious after the deletion of SHARPIN. Notably, the expression of CD94 and CD22 was downregulated in the spleens of knockout (KO) animals. Nonetheless, the expression of CCR3, CCL11, Il4, and Il13 was upregulated in the esophagi. The expression of NF-κB and phosphorylation of NF-κB and IκB protein significantly diminished in SHARPIN-/- animals. CONCLUSIONS A novel SHARPIN KO hamster was successfully established using the CRISPR/Cas9 system. Abnormal development of secondary lymphoid organs and eosinophil infiltration in multiple organs reveal its potential in delineating SHARPIN function and chronic inflammation.

Lipidomic Profiling of the Epidermis in a Mouse Model of Dermatitis Reveals Sexual Dimorphism and Changes in Lipid Composition before the Onset of Clinical Disease. Metabolites 2020; 10:metabo10070299. [PMID: 32708296 PMCID: PMC7408197 DOI: 10.3390/metabo10070299] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/16/2020] [Revised: 07/17/2020] [Accepted: 07/18/2020] [Indexed: 02/07/2023] Open
Abstract
Atopic dermatitis (AD) is a multifactorial disease associated with alterations in lipid composition and organization in the epidermis. Multiple variants of AD exist with different outcomes in response to therapies. The evaluation of disease progression and response to treatment are observational assessments with poor inter-observer agreement highlighting the need for molecular markers. SHARPIN-deficient mice (Sharpincpdm) spontaneously develop chronic proliferative dermatitis with features similar to AD in humans. To study the changes in the epidermal lipid-content during disease progression, we tested 72 epidermis samples from three groups (5-, 7-, and 10-weeks old) of cpdm mice and their WT littermates. An agnostic mass-spectrometry strategy for biomarker discovery termed multiple-reaction monitoring (MRM)-profiling was used to detect and monitor 1,030 lipid ions present in the epidermis samples. In order to select the most relevant ions, we utilized a two-tiered filter/wrapper feature-selection strategy. Lipid categories were compressed, and an elastic-net classifier was used to rank and identify the most predictive lipid categories for sex, phenotype, and disease stages of cpdm mice. The model accurately classified the samples based on phospholipids, cholesteryl esters, acylcarnitines, and sphingolipids, demonstrating that disease progression cannot be defined by one single lipid or lipid category.

Abstract
Spontaneous mutations in the SHANK-associated RH domain interacting protein (Sharpin) resulted in a severe autoinflammatory type of chronic proliferative dermatitis, inflammation in other organs, and lymphoid organ defects. To determine whether cell-type restricted loss of Sharpin causes similar lesions, a conditional null mutant was created. Ubiquitously expressing cre-recombinase recapitulated the phenotype seen in spontaneous mutant mice. Limiting expression to keratinocytes (using a Krt14-cre) induced a chronic eosinophilic dermatitis, but no inflammation in other organs or lymphoid organ defects. The dermatitis was associated with a markedly increased concentration of serum IgE and IL18. Crosses with S100a4-cre resulted in milder skin lesions and moderate to severe arthritis. This conditional null mutant will enable more detailed studies on the role of SHARPIN in regulating NFkB and inflammation, while the Krt14-Sharpin-/- provides a new model to study atopic dermatitis.

Abstract
Psoriasis is an autoimmune skin disease which characteristic of a well-demarcated, erythematous, raised lesion with silvery-white dry scale. Although the mechanism of psoriasis has not been fully understood so far, much progress has been made in understanding many of its complex potential mechanism, particularly the crucial role of the IL-23/Th17 axis. There are a large number of psoriasis models that reflect the complexity of the psoriasis mechanisms. In this review, we summarize various psoriasis mouse models, detail the features and molecular mechanisms of these mouse models, and discuss their strengths and limitations for psoriasis research. The development of mouse models of psoriasis provide an important basis for studying psoriasis pathogenesis and antipsoriatic drugs development. Therefore, the application of various psoriasis mouse models in antipsoriatic drug development are also discussed.

Lipids are important structural and functional components of the skin. Alterations in the lipid composition of the epidermis are associated with inflammation and can affect the barrier function of the skin. SHARPIN-deficient cpdm mice develop a chronic dermatitis with similarities to atopic dermatitis in humans. Here, we used a recently-developed approach named multiple reaction monitoring (MRM)-profiling and single ion monitoring to rapidly identify discriminative lipid ions. Shorter fatty acyl residues and increased relative amounts of sphingosine ceramides were observed in cpdm epidermis compared to wild type mice. These changes were accompanied by downregulation of the Fasn gene which encodes fatty acid synthase. A profile of diverse lipids was generated by fast screening of over 300 transitions (ion pairs). Tentative attribution of the most significant transitions was confirmed by product ion scan (MS/MS), and the MRM-profiling linear intensity response was validated with a C17-ceramide lipid standard. Relative quantification of sphingosine ceramides CerAS(d18:1/24:0)2OH, CerAS(d18:1/16:0)2OH and CerNS(d18:1/16:0) discriminated between the two groups with 100% accuracy, while the free fatty acids cerotic acid, 16-hydroxy palmitic acid, and docosahexaenoic acid (DHA) had 96.4% of accuracy. Validation by liquid chromatography tandem mass spectrometry (LC-MS/MS) of the above-mentioned ceramides was in agreement with MRM-profiling results. Identification and rapid monitoring of these lipids represent a tool to assess therapeutic outcomes in SHARPIN-deficient mice and other mouse models of dermatitis and may have diagnostic utility in atopic dermatitis.

Abstract
INTRODUCTION Psoriasis is an autoimmune skin disease characterized by red plaques with silver or white multilayered scales with a thickened acanthotic epidermis. Using mouse models of cutaneous inflammation, IL-23/Th17 was identified to have a potential key role in psoriasis. New treatments to slow this inflammatory skin disorder are urgently needed. To aid their discovery, a psoriasis animal model mimicking human psoriasis is urgently needed for their early preclinical evaluation. Areas covered: The authors review animal models of psoriasis and analyze the features and molecular mechanisms involved in these mouse models. The application of various mouse models of psoriasis for drug discovery and development has also been reviewed and the possible molecular targets in psoriasis for future anti-psoriatic drug design is discussed. Expert opinion: So far, it has been difficult to create an animal model that exactly simulates a human disease or condition. The xenotransplantation model is regarded as the closest to incorporating the complete genetic, phenotypic, and immunopathogenic processes of psoriasis. However, the imiquimod (IMQ)-induced model is the most prevalent among psoriatic mouse models due to its ease of use, convenience, and low cost. Further efforts to develop psoriasis-like skin models in mice are needed for the study and treatment of this complex disease.

Abstract
Angiogenesis is a common feature of pathological processes including wound healing, tumor formation, and chronic inflammation. Chronic inflammation can also be associated with dilation or proliferation of lymph vessels. We examined blood vessels and lymphatics and the expression of pro- and anti-angiogenic genes in the skin of SHARPIN-deficient mice which spontaneously develop a chronic proliferative dermatitis (cpdm). The number of blood vessels in the dermis of cpdm mice increased with age as the inflammation progressed. Lymphatics identified by labeling for LYVE1 and podoplanin were moderately dilated, but they were not increased in number. The expression of proangiogenic Vegfa, Flt1 and anti-angiogenic Sema3a mRNA was increased. VEGFA was primarily localized in keratinocytes of cpdm skin. There was also increased expression of Ece1 and Pdpn mRNA. Podoplanin was restricted to lymphatic endothelial cells in normal skin, but fibroblasts in cpdm skin also reacted with anti-podoplanin antibodies indicating that they were activated. The expression of other angiogenic and lymphangiogenic factors was not altered or decreased. These results indicate that cpdm mice may be a useful model to study the pathogenesis of angiogenesis in chronic inflammation.

Abstract
Linear ubiquitination is a post‐translational protein modification recently discovered to be crucial for innate and adaptive immune signaling. The function of linear ubiquitin chains is regulated at multiple levels: generation, recognition, and removal. These chains are generated by the linear ubiquitin chain assembly complex (LUBAC), the only known ubiquitin E3 capable of forming the linear ubiquitin linkage de novo. LUBAC is not only relevant for activation of nuclear factor‐κB (NF‐κB) and mitogen‐activated protein kinases (MAPKs) in various signaling pathways, but importantly, it also regulates cell death downstream of immune receptors capable of inducing this response. Recognition of the linear ubiquitin linkage is specifically mediated by certain ubiquitin receptors, which is crucial for translation into the intended signaling outputs. LUBAC deficiency results in attenuated gene activation and increased cell death, causing pathologic conditions in both, mice, and humans. Removal of ubiquitin chains is mediated by deubiquitinases (DUBs). Two of them, OTULIN and CYLD, are constitutively associated with LUBAC. Here, we review the current knowledge on linear ubiquitination in immune signaling pathways and the biochemical mechanisms as to how linear polyubiquitin exerts its functions distinctly from those of other ubiquitin linkage types.

Differential Involvement of the Npl4 Zinc Finger Domains of SHARPIN and HOIL-1L in Linear Ubiquitin Chain Assembly Complex-Mediated Cell Death Protection. Mol Cell Biol 2016; 36:1569-83.

Abstract
The linear ubiquitin chain assembly complex (LUBAC) participates in NF-κB activation and cell death protection. Loss of any of the three LUBAC subunits (catalytic HOIP, accessory HOIL-1L, or accessory SHARPIN subunit) leads to distinct phenotypes in mice and human. cpdm mice (chronic proliferative dermatitis in mice [cpdm]) that lack SHARPIN exhibit chronic inflammatory phenotypes, whereas HOIL-1L knockout mice exhibit no overt phenotypes, despite sharing highly homologous ubiquitin-like (UBL) and Npl4 zinc finger (NZF) domains. Here, we intercrossed mice lacking HOIL-1L and SHARPIN and found that reduction of HOIL-1L in cpdm mice exacerbated inflammatory phenotypes without affecting characteristic features of cpdm disease, whereas reduction of SHARPIN in HOIL-1L knockout mice provoked no overt phenotypes. Hence, loss of SHARPIN and reduction of LUBAC triggers cpdm phenotypes. We found that the NZF domain of SHARPIN, but not that of HOIL-1L, is critical for effective protection from programmed cell death by enhancing the recruitment of LUBAC to the activated TNFR complex. The binding activity to K63-linked ubiquitin chains that the NZF domain of SHARPIN, but not that of HOIL-1L, possesses appears to be involved in the recruitment. Thus, selective recognition of ubiquitin chains by NZFs in LUBAC underlies the regulation of LUBAC function.

Abstract
SHARPIN is an essential component of the linear ubiquitin chain assembly complex (LUBAC) complex that controls signalling pathways of various receptors, including the tumour necrosis factor receptor (TNFR), Toll-like receptor (TLR) and antigen receptor, in part by synthesis of linear, non-degrading ubiquitin chains. Consistent with SHARPIN's function in different receptor pathways, the phenotype of SHARPIN-deficient mice is complex, including the development of inflammatory systemic and skin diseases, the latter of which depend on TNFR signal transduction. Given the established function of SHARPIN in primary and malignant B cells, we hypothesized that SHARPIN might also regulate T-cell receptor (TCR) signalling and thereby control T-cell biology. Here, we focus primarily on the role of SHARPIN in T cells, specifically regulatory T (Treg) cells. We found that SHARPIN-deficient (Sharpin(cpdm/cpdm) ) mice have significantly reduced numbers of FOXP3(+) Treg cells in lymphoid organs and the peripheral blood. Competitive reconstitution of irradiated mice with mixed bone marrow from wild-type and SHARPIN-deficient mice revealed an overall reduced thymus population with SHARPIN-deficient cells with almost complete loss of thymic Treg development. Consistent with this cell-intrinsic function of SHARPIN in Treg development, TCR stimulation of SHARPIN-deficient thymocytes revealed reduced activation of nuclear factor-κB and c-Jun N-terminal kinase, establishing a function of SHARPIN in TCR signalling, which may explain the defective Treg development. In turn, in vitro generation and suppressive activity of mature SHARPIN-deficient Treg cells were comparable to wild-type cells, suggesting that maturation, but not function, of SHARPIN-deficient Treg cells is impaired. Taken together, these findings show that SHARPIN controls TCR signalling and is required for efficient generation of Treg cells in vivo, whereas the inhibitory function of mature Treg cells appears to be independent of SHARPIN.

Abstract
SHARPIN forms a linear-ubiquitin-chain-assembly complex that promotes signaling via the transcription factor NF-κB. SHARPIN deficiency leads to progressive multi-organ inflammation and immune system malfunction, but how SHARPIN regulates T cell responses is unclear. Here we found that SHARPIN deficiency resulted in a substantial reduction in the number of and defective function of regulatory T cells (Treg cells). Transfer of SHARPIN-sufficient Treg cells into SHARPIN-deficient mice considerably alleviated their systemic inflammation. SHARPIN-deficient T cells displayed enhanced proximal signaling via the T cell antigen receptor (TCR) without an effect on the activation of NF-κB. SHARPIN conjugated with Lys63 (K63)-linked ubiquitin chains, which led to inhibition of the association of TCRζ with the signaling kinase Zap70; this affected the generation of Treg cells. Our study therefore identifies a role for SHARPIN in TCR signaling whereby it maintains immunological homeostasis and tolerance by regulating Treg cells.

Abstract
A large variety of mouse models for human skin, hair, and nail diseases are readily available from investigators and vendors worldwide. Mouse skin is a simple organ to observe lesions and their response to therapy, but identifying and monitoring the progress of treatments of mouse skin diseases can still be challenging. This chapter provides an overview on how to use the laboratory mouse as a preclinical tool to evaluate efficacy of new compounds or test potential new uses for compounds approved for use for treating an unrelated disease. Basic approaches to handling mice, applying compounds, and quantifying effects of the treatment are presented.

Abstract
Increased numbers of eosinophils in the esophagus are common in several esophageal and systemic diseases, and a prominent feature of eosinophilic esophagitis. Mouse models can provide insight into the mechanisms of eosinophil infiltration and their pathogenic role. SHARPIN-deficient cpdm mice develop a chronic proliferative dermatitis and an esophagitis characterized by epithelial hyperplasia and the accumulation of eosinophils in the serosa, submucosa, lamina propria and epithelium of the esophagus. We conducted a detailed investigation of the pathogenesis of the esophagitis by light microscopy, immunohistochemistry, and gene expression as the mice aged from 4 to 10 weeks. The thickness of the esophageal epithelium and the number of eosinophils in the esophagus both increased with age. There were scattered apoptotic epithelial cells in mice at 6-10 weeks of age that reacted with antibodies to activated caspase 3 and caspase 9. The expression of CCL11 (eotaxin-1), IL4, IL13 and TSLP was increased in cpdm mice compared with wild type (WT) mice, and there was no change in the expression of CCL24 (eotaxin-2), IL5 and IL33. The expression of chitinase-like 3 and 4 (YM1 and YM2) proteins, markers of type 2 inflammation, was greatly increased in cpdm mice, and this was replicated in vitro by incubation of WT esophagus in the presence of IL4 and IL13. Immunohistochemistry showed that these proteins were localized in esophageal epithelial cells. The severity of the esophagitis was not affected by crossing SHARPIN-deficient mice with lymphocyte-deficient Rag1 null mice indicating that the inflammation is independent of B and T lymphocytes.

Abstract
Chronic proliferative dermatitis in mice (cpdm) is a spontaneous multiorgan inflammatory disorder with pathological hallmarks similar to atopic dermatitis and psoriasis in humans. Cpdm mice lack expression of SHANK-associated RH domain-interacting protein, an adaptor of the linear ubiquitin assembly complex, which acts in the NF-κB pathway to promote inflammation and protect from apoptosis and necroptosis. Although skin inflammation in cpdm mice is driven by TNF- and RIPK1-induced cell death, the contribution of initiating innate immunity sensors and additional inflammatory pathways remains poorly characterized. In this article, we show that inflammasome signaling, including the expression and activation of the inflammatory caspase-1 and -11 and IL-1 family cytokines, was highly upregulated in the skin of cpdm mice prior to overt disease onset. Genetic ablation of caspase-1 and -11 from cpdm mice significantly reduced skin inflammation and delayed disease onset, whereas systemic immunological disease persisted. Loss of Nlrp3 also attenuated skin disease, albeit more variably. Strikingly, induction of apoptosis and necroptosis effectors was sharply decreased in the absence of caspase-1 and -11. These results position the inflammasome as an important initiating signal in skin disease pathogenesis and provide novel insights about inflammasome and cell death effector cross-talk in the context of inflammatory diseases.

Abstract
Boisson et al. report a human homozygous mutation of HOIP, the gene encoding the catalytic component of the linear ubiquitination chain assembly complex, LUBAC. The missense alleles impair the expression of HOIP, destabilizing the LUBAC complex and resulting in immune cell dysfunction leading to multiorgan inflammation, combined immunodeficiency, subclinical amylopectinosis, and systemic lymphangiectactasia. Inherited, complete deficiency of human HOIL-1, a component of the linear ubiquitination chain assembly complex (LUBAC), underlies autoinflammation, infections, and amylopectinosis. We report the clinical description and molecular analysis of a novel inherited disorder of the human LUBAC complex. A patient with multiorgan autoinflammation, combined immunodeficiency, subclinical amylopectinosis, and systemic lymphangiectasia, is homozygous for a mutation in HOIP, the gene encoding the catalytic component of LUBAC. The missense allele (L72P, in the PUB domain) is at least severely hypomorphic, as it impairs HOIP expression and destabilizes the whole LUBAC complex. Linear ubiquitination and NF-κB activation are impaired in the patient’s fibroblasts stimulated by IL-1β or TNF. In contrast, the patient’s monocytes respond to IL-1β more vigorously than control monocytes. However, the activation and differentiation of the patient’s B cells are impaired in response to CD40 engagement. These cellular and clinical phenotypes largely overlap those of HOIL-1-deficient patients. Clinical differences between HOIL-1- and HOIP-mutated patients may result from differences between the mutations, the loci, or other factors. Our findings show that human HOIP is essential for the assembly and function of LUBAC and for various processes governing inflammation and immunity in both hematopoietic and nonhematopoietic cells.

Abstract
Context: Alopecia areata (AA) is a common form of localized, non-scarring hair loss. The pathogenesis of the disease is unknown. Previous evidence suggested the involvement of Th2 cytokines in disease pathogenesis. Aim: To determine serum level of total IgE, this is mainly influenced by Th2 cytokines, in Egyptian patients with AA. Materials and Methods: Fifty subjects with AA (28 males and 22 females) were selected from Dermatology Outpatient Clinic, Menoufiya University Hospital from February 2012 to December 2012. Subjects with other conditions that might elevate serum IgE were excluded from the study. Fifty age- and sex-matched healthy subjects were selected as a control group. Venous blood samples were taken from cases and controls for measurement of total serum IgE by enzyme-linked immunosorbent assay. Skin biopsy was taken from every case from an active area of hair loss. Results: Total serum IgE was elevated in 27 (54%) cases. Its values among patients ranged from 13.5 IU/ml to 780 IU/ml. There was a statistically significant difference between cases and controls with regard to mean value of serum IgE (P < 0.05). Mean value of IgE did not vary significantly with disease severity, patients’ age, patients’ gender, disease duration, site of lesions, and positive family history of AA. No correlation was found between serum IgE levels and histopathological changes detected in examined cases. Conclusions: Total serum IgE is elevated in AA. This elevation is not related to age, gender, disease duration, disease severity, site of affection or family history of AA.

Abstract
The linear ubiquitin chain assembly complex (LUBAC) ubiquitin ligase complex, composed of HOIL-1L-interacting protein (HOIP), heme-oxidized IRP2 ubiquitin ligase-1L (HOIL-1L), and SHANK-associated RH domain protein, specifically generates linear polyubiquitin chains and is involved in NF-κB activation. Lack of SHANK-associated RH domain protein, which drastically reduces the amount of HOIP and HOIL-1L, causes chronic proliferative dermatitis (cpdm) in mice. Impaired NF-κB activation and augmented apoptosis have been implicated in the pathogenesis of cpdm in mice. In this study, we found that IFN-γ increased the amount of LUBAC by inducing HOIP and HOIL-1L mRNA transcription and enhanced the signal-induced NF-κB activation in embryonic fibroblasts, keratinocytes, and bone marrow-derived macrophages from wild-type and/or cpdm mice; however, IFN-γ failed to augment NF-κB activation in mouse embryonic fibroblasts lacking linear polyubiquitination activity of LUBAC. Moreover, s.c. injection of IFN-γ for 3 wk into the skin of cpdm mice increased the amount of HOIP, suppressed apoptosis, and ameliorated the dermatitis. Inhibition of keratinocyte apoptosis by IFN-γ injection suppressed neutrophil, macrophage, and mast cell infiltration and the amount of TNF-α in the skin of cpdm mice. Similarly, IFN-α also enhanced the amount of HOIP as well as NF-κB activation, inhibited apoptosis, and ameliorated cpdm dermatitis. These results indicate that the IFNs enhance NF-κB activation and ameliorate cpdm dermatitis by augmenting expression of HOIP and HOIL-1L and linear polyubiquitination activity of LUBAC.

Abstract
SHARPIN is a key regulator of NFKB and integrin signaling. Mice lacking Sharpin develop a phenotype known as chronic proliferative dermatitis (CPDM), typified by progressive epidermal hyperplasia, apoptosis of keratinocytes, cutaneous and systemic eosinophilic inflammation, and hypoplasia of secondary lymphoid organs. Rag1(-/-) mice, which lack mature B and T cells, were crossed with Sharpin(-/-) mice to examine the role of lymphocytes in CDPM. Although inflammation in the lungs, liver, and joints was reduced in these double mutant mice, dermatitis was not reduced in the absence of functional lymphocytes, suggesting that lymphocytes are not primary drivers of the inflammation in the skin. Type 2 cytokine expression is increased in CPDM. In an attempt to reduce this aspect of the phenotype, Il4ra(-/-) mice, unresponsive to both IL4 and IL13, were crossed with Sharpin(-/-) mice. Double homozygous Sharpin(-/-) , Il4ra(-/-) mice developed an exacerbated granulocytic dermatitis, acute system inflammation, as well as hepatic necrosis and mineralization. High expression of CHI3L4, normally seen in CPDM skin, was abolished in Sharpin(-/-) , Il4ra(-/-) double mutant mice indicating the crucial role of IL4 and IL13 in the expression of this protein. Cutaneous eosinophilia persisted in Sharpin(-/-) , Il4ra(-/-) mice, although expression of Il5 mRNA was reduced and the expression of Ccl11 and Ccl24 was completely abolished. TSLP and IL33 were both increased in the skin of Sharpin(-/-) mice and this was maintained in Sharpin(-/-) , Il4ra(-/-) mice suggesting a role for TSLP and IL33 in the eosinophilic dermatitis in SHARPIN-deficient mice. These studies indicate that cutaneous inflammation in SHARPIN-deficient mice is autoinflammatory in nature developing independently of B and T lymphocytes, while the systemic inflammation seen in CPDM has a strong lymphocyte-dependent component. Both the cutaneous and systemic inflammation is enhanced by loss of IL4 and IL13 signaling indicating that these cytokines normally play an anti-inflammatory role in SHARPIN-deficient mice.

Abstract
Ubiquitination is a post-translational modification process that has been implicated in the regulation of innate and adaptive immune responses. There is increasing evidence that both ubiquitination and its reversal, deubiquitination, play crucial roles not only during the development of the immune system but also in the orchestration of an immune response by ensuring the proper functioning of the different cell types that constitute the immune system. Here, we provide an overview of the latest discoveries in this field and discuss how they impact our understanding of the ubiquitin system in host defence mechanisms as well as self-tolerance.

Abstract
Mice with spontaneous mutations in the Sharpin gene develop chronic proliferative dermatitis that is characterized by eosinophilic inflammation of the skin and other organs with increased expression of type 2 cytokines and dysregulated development of lymphoid tissues. The mutant mice share phenotypic features with human hypereosinophilic syndromes. The biological function of SHARPIN and how its absence leads to such a complex inflammatory phenotype in mice are poorly understood. However, recent studies identified SHARPIN as a novel modulator of immune and inflammatory responses. The emerging mechanistic model suggests that SHARPIN functions as an important adaptor component of the linear ubiquitin chain assembly complex that modulates activation of NF-κB signalling pathway, thereby regulating cell survival and apoptosis, cytokine production and development of lymphoid tissues. In this review, we will summarize the current understanding of the ubiquitin-dependent regulatory mechanisms involved in NF-κB signalling, and incorporate the recently obtained molecular insights of SHARPIN into this pathway. Recent studies identified SHARPIN as an inhibitor of β1-integrin activation and signalling, and this may be another mechanism by which SHARPIN regulates inflammation. Furthermore, the disrupted lymphoid organogenesis in SHARPIN-deficient mice suggests that SHARPIN-mediated NF-κB regulation is important for de novo development of lymphoid tissues.

Abstract
Peyer’s patches (PP) are an important component in the immune response against intestinal pathogens. Two independent, spontaneous mutations in the mouse Sharpin gene (Sharpincpdm and Sharpincpdm-Dem) result in the absence of PP and disrupted splenic white pulp in adult mice, although a full complement of lymph nodes is present. Here we report that rudimentary PP begin to develop in Sharpincpdm mice during embryogenesis, but lack the organizational patterns that are typical of this tissue. In the present study, small intestines examined at weekly intervals from birth to maturity showed spontaneous regression of PP in mutant mice with concurrent infiltration of granulocytes. At 5 to 6 weeks of age, only indistinct remnants of granulocytic accumulations remain. Transplantation of normal bone marrow into Sharpincpdm mice at 7 days of age did not prevent regression of PP in bone marrow chimeras examined at 7 to 8 weeks of age. These findings indicate that SHARPIN expression is required for the normal development and maintenance, but not initiation, of PP.

Abstract
We report the clinical description and molecular dissection of a new fatal human inherited disorder characterized by chronic auto-inflammation, invasive bacterial infections and muscular amylopectinosis. Patients from two kindreds carried biallelic loss-of-expression and loss-of-function mutations in HOIL1, a component the linear ubiquitination chain assembly complex (LUBAC). These mutations resulted in impairment of LUBAC stability. NF-κB activation in response to interleukin-1β (IL-1β) was compromised in the patients’ fibroblasts. By contrast, the patients’ mononuclear leukocytes, particularly monocytes, were hyperresponsive to IL-1β. The consequences of human HOIL-1 and LUBAC deficiencies for IL-1β responses thus differed between cell types, consistent with the unique association of auto-inflammation and immunodeficiency in these patients. These data suggest that LUBAC regulates NF-κB-dependent IL-1β responses differently in different cell types.

Abstract
Spontaneous mutations of the Sharpin (SHANK-associated RH domain-interacting protein, other aliases: Rbckl1, Sipl1) gene in mice result in systemic inflammation that is characterized by chronic proliferative dermatitis and dysregulated secretion of T helper1 (Th1) and Th2 cytokines. The cellular and molecular mechanisms underlying this inflammatory phenotype remain elusive. Dendritic cells may contribute to the initiation and progression of the phenotype of SHARPIN-deficient mice because of their pivotal role in innate and adaptive immunity. Here we show by flow cytometry that SHARPIN- deficiency did not alter the distribution of different DC subtypes in the spleen. In response to TOLL-like receptor (TLR) agonists LPS and poly I:C, cultured bone marrow-derived dendritic cells (BMDC) from WT and mutant mice exhibited similar increases in expression of co-stimulatory molecules CD40, CD80, and CD86. However, stimulated SHARPIN-deficient BMDC had reduced transcription and secretion of pro-inflammatory mediators IL6, IL12P70, GMCSF, and nitric oxide. Mutant BMDC had defective activation of NF-κB signaling, whereas the MAPK1/3 (ERK1/2) and MAPK11/12/13/14 (p38 MAP kinase isoforms) and TBK1 signaling pathways were intact. A mixed lymphocyte reaction showed that mutant BMDC only induced a weak Th1 immune response but stimulated increased Th2 cytokine production from allogeneic naïve CD4(+) T cells. In conclusion, loss of Sharpin in mice significantly affects the immune function of DC and this may partially account for the systemic inflammation and Th2-biased immune response.

Abstract
The ubiquitin conjugation system regulates a wide variety of biological phenomena, including protein degradation and signal transduction, by regulating protein function via polyubiquitin conjugation in most cases. Several types of polyubiquitin chains exist in cells, and the type of polyubiquitin chain conjugated to a protein seems to determine how that protein is regulated. We identified a novel linear polyubiquitin chain and the ubiquitin-protein ligase complex that assembles it, designated LUBAC. Both were shown to have crucial roles in the canonical NFκB activation pathway. This year, three groups, including our laboratory, identified SHARPIN as a new subunit of LUBAC. Of great interest, Sharpin was identified as a causative gene of chronic proliferative dermatitis in mice (cpdm), which is characterized by numerous inflammatory symptoms including chronic dermatitis, arthritis and immune disorders. Deletion of SHARPIN drastically reduces the amount of LUBAC and attenuates signal-induced NFκB activation. The pleomorphic symptoms of cpdm mice suggest that LUBAC-mediated NFκB activation may play critical roles in mammals and be involved in various disorders. A forward look into the linear polyubiquitin research is also discussed.

Abstract
Precise control of the innate immune response is essential to ensure host defense against infection while avoiding inflammatory disease. Systems-level analyses of Toll-like receptor (TLR)-stimulated macrophages suggested that SHANK-associated RH domain-interacting protein (SHARPIN) might play a role in the TLR pathway. This hypothesis was supported by the observation that macrophages derived from chronic proliferative dermatitis mutation (cpdm) mice, which harbor a spontaneous null mutation in the Sharpin gene, exhibited impaired IL-12 production in response to TLR activation. Systems biology approaches were used to define the SHARPIN-regulated networks. Promoter analysis identified NF-κB and AP-1 as candidate transcription factors downstream of SHARPIN, and network analysis suggested selective attenuation of these pathways. We found that the effects of SHARPIN deficiency on the TLR2-induced transcriptome were strikingly correlated with the effects of the recently described hypomorphic L153P/panr2 point mutation in Ikbkg [NF-κB Essential Modulator (NEMO)], suggesting that SHARPIN and NEMO interact. We confirmed this interaction by co-immunoprecipitation analysis and furthermore found it to be abrogated by panr2. NEMO-dependent signaling was affected by SHARPIN deficiency in a manner similar to the panr2 mutation, including impaired p105 and ERK phosphorylation and p65 nuclear localization. Interestingly, SHARPIN deficiency had no effect on IκBα degradation and on p38 and JNK phosphorylation. Taken together, these results demonstrate that SHARPIN is an essential adaptor downstream of the branch point defined by the panr2 mutation in NEMO.

Abstract
Autoinflammatory diseases are a heterogeneous group of congenital diseases characterized by the presence of recurrent inflammation, in the absence of infectious agents, detectable autoantibodies or antigen-specific autoreactive T-cells. SHARPIN deficient mice presents multiorgan chronic inflammation without known autoantibodies or autoreactive T-cells, designated Sharpin(cpdm). Histological studies demonstrated epidermal hyperproliferation, Th-2 inflammation, and keratinocyte apoptosis in this mutant. The mutant mice have decreased behavioral mobility, slower growth, and loss of body weight. Epidermal thickness and mitotic epidermal cells increase along with disease development. K5/K14 expression is distributed through all layers of epidermis, along with K6 expression in interfollicular epidermis, suggesting epidermal hyperproliferation. K1/K10 is only detectable in outer layers of spinosum epidermis, reflecting accelerated keratinocyte migration. Alpha smooth muscle actin is overexpressed in skin blood vessels, which may release the elevated white blood cells to dermis. CD3(+)CD45(+) cells and granulocytes, especially eosinophils and mast cells, aggregate in the mutant skin. TUNEL assay, together with Annexin-V/propidium iodide FACS analysis, confirmed the increase of apoptotic keratinocytes in skin. These data validate and provide new lines of evidence of the proliferation-inflammation-apoptosis triad in Sharpin(cpdm) mice, an NFκB activation autoinflammatory disease.

Abstract
BACKGROUND The chronic proliferative dermatitis mutation (CPDM) in mice, due to Sharpin deficiency (Sharpin(cpdm)), is a multisystem disorder characterized by peripheral blood eosinophilia and eosinophil infiltration of affected tissues including the skin, bone marrow, spleen, lung, heart, and other organs. The epidermis has numerous apoptotic keratinocytes which increase with age, coalesce, form vesicles, and rupture causing ulceration. OBJECTIVE To clarify the molecular pathways involved in the keratinocyte apoptosis caused by loss of function of SHARPIN in mice. METHOD 10-week-old Sharpin(cpdm) and wildtype mice were used for experiments. Ultrastructural changes of skin were evaluated by transmission electron microscopy. Cross points of mitochondrial pathway were analyzed by in vitro and in vivo cellular and molecular assays. RESULTS 77.5% skin cells in Sharpin(cpdm) mice were functionally apoptotic and dead cells, compared to only 18.1% unhealthy skin cells in wildtype mice, indicated by annexin-V/propidium iodide FACS analysis. Mitochondria in keratinocytes were disrupted containing prominent electron dense inclusions and membrane potential depolarization, accompanied by a shift in protein expression between the anti-apoptotic BCL2 and pro-apoptotic BAX proteins. Enzymatic activities of caspases 9 and 3, but not 8, were markedly increased in Sharpin(cpdm) keratinocytes. Caspase-3 was cleaved in most cells in skin of 10-week-old mutant mice. CONCLUSION The present results indicated that keratinocyte apoptosis in Sharpin(cpdm) mice was regulated by an intrinsic caspase-dependent mitochondria pathway.

Abstract
The NF-κB pathway performs pivotal roles in diverse physiological processes such as immunity, inflammation, proliferation, and apoptosis. NF-κB is kept inactive in the cytoplasm through association with inhibitors (IκB), and translocates to the nucleus to activate its target genes after the IκBs are phosphorylated and degraded. Here, we demonstrate that loss of function of SHANK-associated RH domain interacting protein (SHARPIN) leads to activation of NF-κB signaling in skin, resulting in the development of an idiopathic hypereosinophilic syndrome (IHES) with eosinophilic dermatitis in C57BL/KaLawRij-Sharpin(cpdm)/RijSunJ mice, and clonal expansion of B-1 B cells and CD3(+)CD4(-)CD8(-) T cells. Transcription profiling in skin revealed constitutive activation of classical NF-κB pathways, predominantly by overexpressed members of IL1 family. Compound-null mutants for both the IL1 receptor accessory protein (Il1rap(tm1Roml)) and SHARPIN (Sharpin(cpdm)) resulted in mice having decreased skin disease severity. Inhibition of IκBA degradation by the proteasome inhibitor bortezomib alleviated the dermatitis in Sharpin(cpdm) mice. These results indicate that absence of SHARPIN causes IHES with eosinophilic dermatitis by NF-κB activation, and bortezomib may be an effective treatment for skin problems of IHES.

Abstract
Background. Interleukin-4 (IL-4), a Th2 cytokine, can stimulate immunoglobulin E (IgE) transcription. No previous studies evaluated the genetic mechanisms in nonatopic AA patients with elevated serum IgE.
Objective. To compare serum IL-4 and total IgE levels between Egyptian nonatopic AA patients and healthy subjects and to investigate a possible relation to HLA-DRB1 alleles. Results. Serum IL-4 and total IgE were measured by ELISA in 40 controls and 54 nonatopic AA patients. Patients' HLA-DRB1 typing by sequence specific oligonucleotide probe technique was compared to normal Egyptian population. We found significantly elevated serum IL-4 and total IgE in AA patients (particularly alopecia universalis, AU, and chronic patients) (P < .01). HLA-DRB1*11 is a general susceptibility/chronicity allele. DRB1*13 is a protective allele. DRB1*01 and DRB1*07 are linked to chronicity. Localized AA showed decreased DRB1*03 and DRB1*07. Extensive forms showed increased DRB1*08 and decreased DRB1*04. Elevated IL4 and IgE were observed in patients with DRB1*07 and DRB1*11 not DRB1*04.
Conclusion. Serum IL-4 and IgE are elevated in nonatopic AA patients, particularly AU and chronic disease. Relevant susceptibility, chronicity, and severity HLADRB1 alleles may have a role in determining type, magnitude, and duration of immune response in AA favouring increased IL4 and IgE.

Abstract
A large variety of mouse models for human skin and adnexa diseases are readily available from investigators and vendors worldwide. While the skin is an obvious organ to observe lesions and their response to therapy, actually treating and monitoring progress in mice can be challenging. This chapter provides an overview on how to use the laboratory mouse as a preclinical tool to evaluate efficacy of a new compound or test potential new uses for a compound approved for use for treating an unrelated disease. Basic approaches to handling mice, applying compounds, and quantifying effects of the treatment are presented.

Abstract
Sharpin-deficient (Sharpin(cpdm)) mutant mice develop a chronic eosinophilic dermatitis. To determine the efficacy of eosinophil-depletion in chronic inflammation, Sharpin(cpdm) mice were treated with anti-IL5 antibodies. Mice treated with anti-IL5 had a 90% reduction of circulating eosinophils and a 50% decrease in cutaneous eosinophils after 10 days compared with sham-treated littermates. Reducing the number of eosinophils resulted in increased severity of alopecia and erythema and a significant increase in epidermal thickness. Skin homogenates from mice treated with anti-IL5 had decreased mRNA expression of arylsulfatase B (Arsb), diamine oxidase (amiloride-binding protein 1, also called histaminase; Abp1) and Il10, which are mediators that eosinophils may release to quench inflammation. Skin homogenates from mice treated with anti-IL5 also had decreased mRNA expression of Il4, Il5, Ccl11, kit ligand (Kitl) and Tgfa; and increased mRNA expression of Tgfb1, Mmp12 and tenascin C (Tnc). In order to further decrease the accumulation of eosinophils, Sharpin(cpdm) mice were crossed with IL5 null mice. Il5(-/-), Sharpin(cpdm)/Sharpin(cpdm) mice had a 98% reduction of circulating eosinophils and a 95% decrease in cutaneous eosinophils compared with IL5-sufficient Sharpin(cpdm) mice. The severity of the lesions was similar between IL5-sufficient and IL5-deficient mice. Double mutant mice had a significant decrease in Abp1, and a significant increase in Tgfb1, Mmp12 and Tnc mRNA compared with controls. These data indicate that eosinophils are not essential for the development of dermatitis in Sharpin(cpdm) mice and suggest that eosinophils have both pro-inflammatory and anti-inflammatory roles in the skin of these mice.

Abstract
Psoriasis is the most common autoimmune disease in man and is characterized by focal to coalescing raised cutaneous plaques with consistent scaling and variable erythema. The specific pathogenesis of psoriasis is not completely understood, but the underlying mechanisms involve a complex interplay between epidermal keratinocytes, T lymphocytes as well as other leukocytes (including dendritic cells and other antigen presenting cells [APCs]), and vascular endothelium. Mirroring the complexity of mechanisms that underlie psoriasis, there are a relatively large number of models of psoriasis. Each model is based on a slightly different pathogenic mechanism, and each has its similarities to psoriasis as well as its limitations. In general, psoriasis models can be very broadly divided on the basis of the pathogenic mechanisms that interplay to cause psoriasis, with the addition of several relatively poorly defined spontaneous murine mutant models. Other than the spontaneous mutant models, murine models of psoriasis can be divided into those that are genetically engineered (transgenic and knockout—with manipulation of either the epidermis, leukocytes, or the endothelium), and those that are induced (either by immune transfer or by xenotransplantation of skin from psoriatic patients). In addition to the murine models, in vitro human epidermal models have recently become more widely utilized. While no one single model of psoriasis is ideal, many have proven to be extremely valuable in investigating and better understanding the molecular mechanisms that underlie the complex interplay between epidermal keratinocytes, the innate and adaptive immune system, and the vascular endothelium in psoriasis.

Abstract
Homologues of the SHARPIN (SHANK-associated RH domain-interacting protein) gene have been identified in the human, rat and mouse genomes. SHARPIN and its homologues are expressed in many tissues. SHARPIN protein forms homodimers and associates with SHANK in the post-synaptic density of excitatory neurotransmitters in the brain. SHARPIN is hypothesized to have roles in the crosslinking of SHANK proteins and in enteric nervous system function. We demonstrate that two independently arising spontaneous mutations in the mouse Sharpin gene, cpdm and cpdm(Dem), cause a chronic proliferative dermatitis phenotype, which is characterized histologically by severe inflammation, eosinophilic dermatitis and defects in secondary lymphoid organ development. These are the first examples of disease-causing mutations in the Sharpin gene and demonstrate the importance of SHARPIN protein in normal immune development and control of inflammation.

Abstract
Mammalian chitinase-like proteins belong to a family of proteins structurally related to chitinases but devoid of enzymatic activity. They have a postulated role in remodeling of extracellular matrix and defense mechanisms against chitin-containing pathogens. The expression of these proteins is increased in parasitic infections and allergic airway disease, but their expression in dermatitis has not been examined. The mRNA expression of two chitinase 3-like (Chi3L) proteins, Chi3L3 (Ym1) and Chi3L4 (Ym2), was determined in the skin of normal mice, chronic proliferative dermatitis (cpdm/cpdm) mutant mice and mice with experimentally induced contact hypersensitivity reaction. The localization of Chi3L3 and Chi3L4 proteins in cells was determined by fluorescence microscopy of double-labeled frozen sections of skin, and confirmed in vitro by stimulation of macrophages and mast cells with cytokines. Quantitative RT-PCR demonstrated a 976-fold increase of Chi3l4 mRNA expression and a 24-fold increase of Chi3l3 mRNA expression in the skin of cpdm/cpdm mice. Their expression was also increased in the ears of mice with 2,4-dinitrofluorobenzene-induced contact hypersensitivity, but the increase was greater for Chi3l3 mRNA (51-fold) than Chi3l4 mRNA (32-fold). Western blot analysis with an antibody against Chi3L3 and Chi3L4 confirmed the increased amount of these proteins in the skin of cpdm/cpdm mice. Two-color immunofluorescence identified macrophages, dendritic cells and mast cells as cellular sources of Chi3L3 and Chi3L4 proteins. Eosinophils and neutrophils did not contain detectable concentrations of these proteins. Treatment of macrophages and mast cells in vitro with interleukin-4 induced expression of Chi3l3 and Chi3l4 mRNA.

Abstract
Chemokines direct the migration of leukocytes to sites of inflammation and are potential targets for anti-inflammatory therapy. Chronic proliferative dermatitis (cpdm/cpdm) mutant mice develop a persistent eosinophilic dermatitis associated with increased T(H)2 cytokines in the skin. Expression patterns of chemokines in the skin of cpdm/cpdm mice were evaluated to define the mechanisms driving cutaneous infiltration by leukocytes. RNA isolated from the skin of mutant and littermate control mice revealed a significant increase in Ccl1 (TCA-3), Ccl2 (MCP-1), Ccl11 (eotaxin), Ccl17 (TARC), Cxcl10 (IP-10), and the chemokine receptor Ccr3. The concentration of CCL11 protein was increased two- to threefold in the skin of cpdm/cpdm mice by enzyme-linked immunosorbent assay. In vitro culture of primary dermal fibroblasts from cpdm/cpdm and control mice with tumor necrosis factor, IL-4, and IL-13 stimulation did not reveal differences in their ability to secrete CCL11, suggesting that the increased chemokine expression observed in the skin of cpdm/cpdm mice is most likely caused by the increased T(H)2 cytokines in the dermis of this mouse model. Treatment of cpdm/cpdm mice with CCL11-neutralizing polyclonal antibodies did not affect the number of eosinophils in the skin or the severity of the dermatitis. Neutralizing multiple chemokines or chemokine receptors may be necessary to decrease eosinophil accumulation. The cpdm/cpdm mutant mouse is a potentially useful model to determine the role of various chemokines in eosinophil accumulation in chronic inflammation.

Abstract
Alopecia areata is a suspected autoimmune hair loss disease. In a rodent model, alopecia areata can be induced in normal haired C3H/HeJ mice by transfer of skin grafts from mice with spontaneous alopecia areata. At weeks 2, 4, 6, and 10 after surgery, grafted mice were euthanized, skin collected and processed for histology, and RNA extracted. Age-matched sham-grafted mice, and mice with and without spontaneous alopecia areata, were similarly processed. For comparison, skin biopsies from alopecia areata and androgenetic alopecia affected humans were also collected. Skin mRNA processed to cDNA was analyzed using Affymetrix mouse 11K and human 6800 gene chip(R) array technology. Microarray results indicated 42 known genes upregulated or downregulated during onset of mouse alopecia areata consistent with an inflammatory cell-mediated disease pathogenesis involving antigen presentation, costimulation, and a T helper 1 lymphocyte response. In contrast, 114 genes, many regulating immunoglobulin response, were altered late in disease development. In alopecia areata affected humans, 95 genes were significantly modulated. As confirmation of microarray analysis results, lymph node and spleen cells from alopecia areata affected mice injected into normal haired littermates transferred the alopecia areata phenotype. Alopecia areata onset could be inhibited in skin-grafted mice by modulation with B7.1- and B7.2-specific monoclonal antibodies. In addition, depletion of CD4+ CD8+ expressing cells in chronic alopecia areata affected mice using monoclonal antibodies permitted hair regrowth. The results consistently demonstrated the importance of an immune cell-mediated disease mechanism in alopecia areata pathogenesis and suggested targeting antigen-presenting cells and reactive lymphocytes may be effective in alopecia areata treatment.

Abstract
Numerous transgenic, targeted mutagenesis (so-called knockouts), conditional (so-called "gene switch") and spontaneous mutant mice develop abnormal hair phenotypes. The number of mice that exhibit such abnormalities is increasing exponentially as genetic engineering methods become routine. Since defined abnormalities in hair follicle morphogenesis, cycling and/or structure in such mutant mice provide important clues to the as yet poorly understood functional roles of many gene products, it is useful to summarize and classify these mutant mice according to their hair phenotype. This review provides a corresponding, annotated table of mutant mice with hair abnormalities, classifying the latter into 6 categories, 1) abnormally low number of hair follicles, 2) disorders of hair morphogenesis, 3) of hair follicle cycling, 4) of hair follicle structure 5) of sebaceous gland structure, and 6) hair growth disorders as a consequence of immunological abnormalities. This annotated table should serve as a useful source of reference for anyone who is interested in the molecular controls of hair growth, for investigators who are looking for mouse models to explore or compare the functional activities of their gene of interest, and for comparing the hair phenotype of newly generated mouse mutants with existing ones.
