Biomarkers and Their Possible Functions in the Intestinal Microenvironment of Chagasic Megacolon: An Overview of the (Neuro)inflammatory Process. J Immunol Res 2021; 2021:6668739. [PMID: 33928170 PMCID: PMC8049798 DOI: 10.1155/2021/6668739] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/25/2020] [Revised: 03/08/2021] [Accepted: 03/19/2021] [Indexed: 12/13/2022] Open
Abstract
The association between inflammatory processes and intestinal neuronal destruction during the progression of Chagasic megacolon is well established. However, many other components play essential roles, both in the long-term progression and control of the clinical status of patients infected with Trypanosoma cruzi. Components such as neuronal subpopulations, enteric glial cells, mast cells and their proteases, and homeostasis-related proteins from several organic systems (serotonin and galectins) are differentially involved in the progression of Chagasic megacolon. This review is aimed at revealing the characteristics of the intestinal microenvironment found in Chagasic megacolon by using different types of already used biomarkers. Information regarding these components may provide new therapeutic alternatives and improve the understanding of the association between T. cruzi infection and immune, endocrine, and neurological system changes.

Abstract
CLIPR-59 is a new member of the cytoplasmic linker proteins (CLIP) family mainly localized to the trans-Golgi network. We show here that Clipr-59 expression in mice is restricted to specific pools of neurons, in particular motoneurons (MNs), and progressively increases from embryonic day 12.5 (E12.5) until the first postnatal days. We generated a Clipr-59 knockout mouse model that presents perinatal lethality due to respiratory defects. Physiological experiments revealed that this altered innervation prevents the normal nerve-elicited contraction of the mutant diaphragm that is reduced both in amplitude and fatigue-resistance at E18.5, despite unaffected functional muscular contractility. Innervation of the mutant diaphragm is not altered until E15.5, but is then partially lost in the most distal parts of the muscle. Ultrastructural observations of neuromuscular junctions (NMJs) in the distal region of the diaphragm reveal a normal organization, but a lower density of nerve terminals capped by terminal Schwann cells in E18.5 mutant when compared with control embryos. Similar defects in NMJ stability, with a hierarchy of severity along the caudo-rostral axis, are also observed in other muscles innervated by facial and spinal MNs in Clipr-59 mutant mice. Clipr-59 deficiency therefore affects axon maintenance but not axon guidance toward muscle targets. Thus, CLIPR-59 is involved in the stabilization of specific motor axons at the NMJ during mouse late embryogenesis and its role is crucial for mouse perinatal development.

Abstract
Peripherin is a type III intermediate filament protein normally undetectable in most brain neurons. Here, we report a similar pattern of peripherin expression in the brains of both mice treated with systemic injections of kainic acid (KA) and in peripherin transgenic mice (Per mice) over-expressing the normal peripherin gene under its own promoter. Double-immunofluorescence labeling revealed a partial co-localization of peripherin with the microtubule-associated protein MAP2, but not with neurofilament proteins. Electrophysiological studies revealed that synaptic plasticity was markedly altered in Per mice: in CA1, long-term potentiation (LTP) was decreased in Per slices (+29 +/- 2.0%, vs. +58 +/- 5.4%, in WT); while in CA3, LTP was increased in Per (+63 +/- 3.5% vs. +43 +/- 2.4.0%). In the hippocampus of Per mice, the levels of MAP2 were decreased, though synaptophysin and PSD95 remained unchanged. These intriguing findings suggest a role of peripherin in the alteration of hippocampal synaptic plasticity.

Abstract
BACKGROUND The rare desmoplastic and spindle cell variants of malignant melanoma exhibit histological and biochemical features suggestive of early Schwann cell differentiation. These features include a spindle-shaped morphology, neurotropism, and the expression of the low affinity nerve growth factor receptor (p75NGFR). METHODS We evaluated by immunohistochemistry (using formalin-fixed, paraffin-embedded tissues) nine desmoplastic and three spindle cell melanomas for the expression of peripherin, p75NGFR, neural cell adhesion molecule (CD56/N-CAM), and growth-associated phosphoprotein-43 (GAP-43). Peripherin is expressed in the neural crest and in neurons, but not in cells committed to the Schwann cell lineage. p75NGFR and CD56/N-CAM also are expressed in early neural crest cells, but persist in unmyelinated and early premyelinating Schwann cells. GAP-43 is expressed in unmyelinated Schwann cells, but is downregulated in the later premyelinating to promyelinating stages of cells committed to the Schwann cell lineage. RESULTS Peripherin was expressed in 7/12 (58%), p75NGFR in 4/12 (33%), and CD56/N-CAM in 6/12 (50%) of the desmoplastic and spindle cell melanomas. GAP-43 was not expressed (0%) in any of the 12 melanomas (chi2, p = 0.05). CONCLUSIONS Desmoplastic and spindle cell melanomas express protein markers common to cells of the neural crest and to neurons similar to the immunophenotype previously reported for epithelioid cell melanomas. The expression of peripherin and the lack of expression of GAP-43 further define that these rare subtypes of melanoma do not recapitulate the later committed stages of Schwann cell differentiation.

Abstract
Peripherin is a type III intermediate filament predominantly expressed in neurons having direct axonal projections toward peripheral structures. Here, we report that brain injuries can trigger expression of peripherin and the formation of peripherin accumulations in neurons that are normally silent for this gene. Stab lesions made with nitrocellulose implants induced within 4 days the formation of peripherin accumulations, devoid of neurofilament proteins, in thalamic neurites at the site of the lesion. The local administration of interleukin-6 or leukemia inhibitory factor at the site of the stab lesion extended the expression pattern of peripherin to other neuronal subsets in areas of the cortex and/or of the hippocampus adjacent to injury. We also show that transient focal ischemia in mice, a model of stroke, can trigger within 72 h the formation of neuronal peripherin accumulations in neurons of the cortex, thalamus and hippocampus. This new type of potentially noxious intermediate filament protein accumulations, composed of peripherin, may be of relevance to many brain degenerative disorders with occurrence of proinflammatory cytokines.

Abstract
Peripherin is a type III intermediate filament (IF) abundantly expressed in developing neurons, but in the adult, it is primarily found in neurons extending to the peripheral nervous system. It has been suggested that peripherin may play a role in axonal elongation and/or cytoskeletal stabilization during development and regeneration. To further clarify the function of peripherin, we generated and characterized mice with a targeted disruption of the peripherin gene. The peripherin null mice were viable, reproduced normally and did not exhibit overt phenotypes. Microscopic analysis revealed no gross morphological defects in the ventral and dorsal roots, spinal cord, retina and gut, but protein analyses showed increased levels of the type IV IF alpha-internexin in ventral roots of peripherin null mice. Whereas the number and caliber of myelinated motor and sensory axons in the L5 roots remained unchanged in peripherin knockout mice, there was a substantial reduction ( approximately 34%) in the number of L5 unmyelinated sensory fibers that correlated with a decreased binding of the lectin IB4. These results demonstrate a requirement of peripherin for the proper development of a subset of sensory neurons.

Abstract
Peripherin is an intermediate filament involved in growth and development of the peripheral nervous system, and is produced by neurons and the beta cells of the islets of Langerhans. Recently, malignant melanomas and some melanocytic nevi have been shown to express peripherin. It is unknown if Schwann cells, also derived from the neural crest, express peripherin. Expression of peripherin was evaluated by immunohistochemistry in cutaneous lesions characterized by a prominent Schwann cell component including 26 neurofibromas (NF), 10 schwannomas (SCH), seven granular cell tumors, and five palisaded encapsulated neuromas (PEN); 13 neurotized melanocytic nevi (NMN) also were evaluated because these lesions contain Wagner-Meissnerlike structures and type C nevus cells, which exhibit a "schwannian" phenotype. Peripherin was detected in the axons of normal peripheral nerves. NF and PEN contained numerous axons dispersed throughout the lesions, whereas only scattered small nerves were seen in GCT. In SCH, only rare axons were labeled, mostly at the periphery of the lesions. All other cells in these four types of lesions, therefore including Schwann cells, were not labeled. In most NMN, labeled axons were identified within the lesions. In a few cases, rare epithelioid melanocytes within the superficial portions of the nevi were labeled. The Wagner-Meissnerlike structures and type C nevus cells (schwannian) were not labeled in any lesion; however, numerous labeled axons invested these areas. Because there are different relative numbers of peripherin-labeled axons throughout NF, PEN, some nevi, and SCH, analysis of peripherin expression may be helpful in the diagnosis of these lesions. Neurons and some epithelioid melanocytes, in contrast to type C nevus cells and Schwann cells of NF and SCH, express peripherin, providing further evidence for a transition from a more neuronal to a more schwannian phenotype during the normal maturation sequence of melanocytes in nevi.

Abstract
Peripherin is an intermediate filament involved in growth and development of the peripheral nervous system and is localized to neurons, some other cells derived from neural tube and neural crest, and some neuroendocrine cells (e.g. beta cells of islets of Langerhans). Peripherin also has been demonstrated in neuroblastomas and cutaneous neuroendocrine (Merkel cell) carcinomas. The expression of peripherin by other cells derived from the neural crest is unknown. We evaluated by immunohistochemistry 74 cutaneous melanocytic lesions including primary invasive malignant melanoma (IMM), melanoma in situ (MIS), atypical nevus (nevus with architectural disorder and cytologic atypia of melanocytes) (AN), spindle and epithelioid cell nevus (Spitz nevus) (SN), blue nevus (BN), and common intradermal benign melanocytic nevus (BMN) for expression of peripherin. Peripherin was detected in a cytoplasmic distribution within tumor cells in 14/14 IMM and 8/10 MIS. For IMM, peripherin localized to both the intraepidermal and invasive dermal components. Peripherin was detected in 10/10 AN and 9/9 SN, being localized to the intraepidermal component and, focally, to the superficial dermal component of the lesions. The dendritic nevus cells in 15/15 BN also expressed peripherin. For most of the BMN, expression of peripherin was absent or limited to rare, scattered cells in the superficial portion of the lesions. Melanocytes in adjacent normal skin were not labeled in any of the lesions studied. These results indicate that expression of peripherin is common in both benign and malignant melanocytic lesions, but not in normal resting adult melanocytes. Among benign lesions, expression of peripherin in the dermal component is rare except in the dendritic cells of BN. These findings provide evidence that the expression of peripherin, a marker of neuronal differentiation, is maintained by IMM, MIS, and BN, but is lost in the normal maturational sequence of the dermal component of other melanocytic lesions.

Abstract
Peripherin is a neuron-specific intermediate filament (IF) protein, found primarily in phylogenetically old regions of the nervous system. Whereas other neuronal IF genes have only two to three introns and are scattered in the genome, the peripherin gene (PRPH) has a complex intron-exon structure like nonneuronal IF genes that are clustered in tandem arrays, e.g., those encoding the keratins. We used a cosmid containing the human peripherin gene (PRPH) to determine its chromosomal location in relationship to nonneuronal IF genes. Using a rodent-human mapping panel, we localized the PRPH gene to human chromosome 12. Since a cluster of keratin genes maps to 12q12-13, polymorphic markers were developed for PRPH and for one of the keratin genes presumed to be in the cluster, keratin 18 (KRT18). Both markers were typed in CEPH reference families. Pairwise and multipoint analyses of the CEPH data revealed that KRT18 is tightly linked to DNA markers D12S4, D12S22, D12S90, D12S96 and D12S103, which lie between D12S18 and D12S8, with odds greater than 1000:1. These markers are physically located at 12q11-13, thus supporting the fine localization of KRT18 in or near the group of type II keratins in this region. Furthermore, linkage analysis showed that the peripherin gene (PRPH) is tightly linked to KRT18 (Z = 15.73, theta = 0.013), and therefore appears to be in close proximity to the cluster.
