Abstract
Trichodysplasia spinulosa (TS) is a unique, rare clinical and histological dermatologic entity described mainly in a setting of immunosuppression. It is caused by a novel human polymoavirus, TS-associated polyomavirus. Reduction of immunosuppression and/or anti-viral therapy is the main therapeutic strategies used to treat such cases. We report a biopsy-proven case of TS in a male renal transplant patient who presented to a dermatology outpatient clinic in Montreal, Canada, in 2015. He was managed with valgancyclovir with no obvious response. Subsequently, a trial of topical imiquimod was commenced. Awareness of TS can prompt early diagnosis and management to prevent possible complications.

Abstract
Since Merkel cell polyomavirus (MCPyV) was linked as the predominant etiology of Merkel cell carcinoma (MCC) in 2008, three additional human polyomaviruses (HPyV) have been definitively linked to cutaneous diseases-trichodysplasia spinulosa virus (TSPyV) and human polyomavirus 6 and 7 (HPyV6, HPyV7). TSPyV contributes to the development of trichodysplasia spinulosa (TS), and HPyV6/7 is associated closely with the eruption of pruritic and dyskeratotic dermatoses (PDD). Clinically, MCC is treated with surgical excision and radiation with adjuvant chemotherapy, although newer treatment options include immune checkpoint inhibition. These novel immunotherapies hold promise for the treatment of metastatic MCC, but resistance and side effects prevent a significant proportion of patients from realizing their benefits. Based on previous case reports, the standard of care for the less deadly but disfiguring cutaneous disease TS include immunosuppressant (IS) reduction, the use of antivirals such as cidofovir (CDV) or valganciclovir (VGCV), or a combination of these treatments. Similar treatments were attempted for PDD, but oral acitretin was found to be most effective. As MCC, TS, and PDD are rare diseases, further research is required for effective treatments. In this review, we summarize clinical trials, preclinical studies, and case reports that present outcomes and side effects of current and emerging treatments for HPyV-associated cutaneous diseases, offering a comprehensive resource for clinical application and prospective clinical trials.

Abstract
We describe 3 patients in California, USA, with trichodysplasia spinulosa polyomavirus (TSPyV) infection of endothelium after steroid administration. We detected TSPyV RNA in tissue specimens by in situ hybridization, which revealed localization to endothelial cells. These cases suggest that diseases associated with endothelial inflammation could be associated with TSPyV infection.

Abstract
As their name indicates, polyomaviruses (PyVs) can induce tumors. Mouse PyV, hamster PyV and raccoon PyV have been shown to cause tumors in their natural host. During the last 30 years, 15 PyVs have been isolated from humans. From these, Merkel cell PyV is classified as a Group 2A carcinogenic pathogen (probably carcinogenic to humans), whereas BKPyV and JCPyV are class 2B (possibly carcinogenic to humans) by the International Agency for Research on Cancer. Although the other PyVs recently detected in humans (referred to here as novel HPyV; nHPyV) share many common features with PyVs, including the viral oncoproteins large tumor antigen and small tumor antigen, as their role in cancer is questioned. This review discusses whether the nHPyVs may play a role in cancer based on predicted and experimentally proven functions of their early proteins in oncogenic processes. The functional domains that mediate the oncogenic properties of early proteins of known PyVs, that can cause cancer in their natural host or animal models, have been well characterized and we examined whether these functional domains are conserved in the early proteins of the nHPyVs and presented experimental evidence that these conserved domains are functional. Furthermore, we reviewed the literature describing the detection of nHPyV in human tumors.

Abstract
Polyomaviruses infect many species, including humans. So far, 15 polyomaviruses have been described in humans, but it remains to be established whether all of these are genuine human polyomaviruses. The most recent polyomavirus to be detected in a person is Quebec polyomavirus (QPyV), which was identified in a metagenomic analysis of a stool sample from an 85-year-old hospitalized man. We used PCR to investigate the presence of QPyV DNA in urine samples from systemic lupus erythematosus (SLE) patients (67 patients; 135 samples), multiple sclerosis patients (n = 35), HIV-positive patients (n = 66) and pregnant women (n = 65). Moreover, cerebrospinal fluid from patients with suspected neurological diseases (n = 63), nasopharyngeal aspirates from patients (n = 80) with respiratory symptoms and plasma samples from HIV-positive patients (n = 65) were examined. QPyV DNA was found in urine from 11 (16.4%), 10 (15.4%) and 5 (14.3%) SLE patients, pregnant women, and multiple sclerosis patients, respectively. No QPyV DNA could be detected in the other samples. Alignment with the only available QPyV sequence in the GenBank revealed amino acid substitutions in the HI-loop of capsid protein VP1 in 6/28 of the isolates. Our results show that QPyV viruria can occur, but whether it may cause clinical symptoms in the patients remains to be determined.

Abstract
Introduction: Lung transplant recipients are at the highest risk of infectious complications among all solid-organ transplant (SOT) recipients. In the current era, many standardized protocols in terms of diagnostic algorithms, prophylaxis, and therapeutic strategies have improved the management of the most common infectious complications. Conversely, diagnosis of rare infections can be particularly challenging and this can delay appropriate treatment.Areas covered: This article will review the epidemiology, clinical presentation, diagnostic and therapeutic management of certain rarely reported viral, fungal, bacterial and parasitic infections in lung transplant recipients.Expert opinion: Once the most frequent infections are excluded, clinical suspicion combined with molecular diagnostic methods such as targeted and broad-spectrum PCRs can allow diagnosis of a rare infection. A multidisciplinary team, including transplant pulmonologists, transplant infectious diseases specialists, microbiologists and pathologists is essential for prompt diagnosis and optimal therapeutic management.

Abstract
Trichodysplasia Spinulosa (TS) is a rare proliferative skin disease that occurs primarily in immunocompromised patients, specifically organ transplant recipients. TS is characterized by uncontrolled inner root sheath cell proliferation and folliculocentric papular eruption that can progress to disfiguring leonine facies when left untreated. TS presents with distinct histological features including the presence of large eosinophilic, trichohyaline granules within hyperproliferating inner root sheath cells of the hair bulb. The discovery of the Trichodysplasia Spinulosa Polyomavirus (TSPyV) and recent studies highlighting the role of TSPyV tumor antigens in cell proliferation pathways have provided new insight into the mechanisms of TS development. In this review, we discuss the expansion of our understanding of TS, specifically over the past 5 years. We summarize novel cases of TS and recent developments in the mechanisms underlying TSPyV-mediated disease progression. We also evaluate advancements in diagnostic methods and treatment options. As the incidence of TS continues to rise, it is becoming critical for clinicians to understand the clinical features of TS and emerging research regarding pathogenesis and therapeutics for early treatment of this potentially disfiguring disease.

Abstract
Trichodysplasia spinulosa-associated polyomavirus (TSPyV or human polyomavirus 8) was identified from patients with trichodysplasia spinulosa, a rare skin disease affecting the faces of immunocompromised patients. Like other polyomaviruses, the TSPyV genome encodes a large T antigen (LT). However, the expression and functions of TSPyV LT in infected cells remain largely unknown. In the present study, we cloned a full-length TSPyV LT cDNA from cells transfected with the full-length of TSPyV LT DNA. Transfection study using green fluorescence protein-tagged LT expression plasmids showed that TSPyV LT was expressed in the nucleus of transfected cells. Analysis of deletion mutants identified a nuclear localization signal in TSPyV LT. Recombinant TSPyV LT exhibited an ATPase activity. TSPyV LT has a chitinase-like domain; however, no chitinase activity was detected. Immunoprecipitation assays revealed that TSPyV LT bound to retinoblastoma 1, but not to p53 in transfected cells. Expression of TSPyV LT in NIH3T3 cells induced colony formation in soft agar, suggesting its transformation activity. These data indicate that TSPyV LT may be associated with the pathogenesis of trichodysplasia spinulosa, which is a hyperplasia of keratinocytes in inner hair follicles.

Abstract
Viruses are intracellular parasites that require a permissive host cell to express the viral genome and to produce new progeny virus particles. However, not all viral infections are productive and some viruses can induce carcinogenesis. Irrespective of the type of infection (productive or neoplastic), viruses hijack the host cell machinery to permit optimal viral replication or to transform the infected cell into a tumor cell. One mechanism viruses employ to reprogram the host cell is through interference with signaling pathways. Polyomaviruses are naked, double-stranded DNA viruses whose genome encodes the regulatory proteins large T-antigen and small t-antigen, and structural proteins that form the capsid. The large T-antigens and small t-antigens can interfere with several host signaling pathways. In this case, we review the interplay between the large T-antigens and small t-antigens with host signaling pathways and the biological consequences of these interactions.

Abstract
In recent years, the Polyomaviridae family grew rapidly, thanks to the introduction of high-throughput molecular techniques. To date, 14 polyomaviruses have been identified in humans but the association with human diseases has been established only for few of them. BKPyV has been associated with nephropathy in kidney transplant patients and hemorrhagic cystitis in hematopoietic stem cell transplant patients; JCPyV to progressive multifocal leukoencephalopathy, mainly in HIV-positive patients; Merkel cell polyomavirus to Merkel cell carcinoma; Trichodysplasia spinulosa polyomavirus to the rare skin disease Trichodysplasia spinulosa; human polyomaviruses 6 and 7 to pruritic rash. Immunocompromised patients are at risk of developing disease. Here, we summarized and discussed the scientific literature concerning the human polyomaviruses biology, seroprevalence and association with human diseases.

Abstract
Trichodysplasia spinulosa (TS) is a rare cutaneous condition associated with the TSPyV and characterized by skin-colored, folliculocentric papules with keratin spicule formation. TS is seen almost exclusively in immunosuppressed individuals, often presenting in patients with a history of solid organ transplantation or chemotherapy for a lymphoreticular malignancy. We report a case of widespread TS in a 9-year-old girl with a history of renal transplantation complicated by BK viremia, which is also caused by a polyomavirus, BKPyV. The clinical presentation of TS in this case morphologically resembled the more common, harmless skin condition known as "lichen nitidus," and was more extensive than expected for TS, creating a diagnostic challenge. This case illustrates an important presentation of severe TS of which transplant teams, oncologists, primary care providers, and dermatologists should be aware.

Abstract
BACKGROUND Human polyomaviruses (HPyVs) are small, nonenveloped, double-stranded DNA viruses that express tumour antigen proteins. Fourteen species of polyomaviruses have been discovered in humans, and since the 2008 discovery of the first cutaneous polyomavirus - Merkel cell polyomavirus (MCPyV) - six more species have been detected in the skin: trichodysplasia spinulosa-associated polyomavirus (TSPyV), HPyV6, HPyV7, HPyV9, HPyV10 and HPyV13. Of these cutaneous species, only MCPyV, TSPyV, HPyV6 and HPyV7 have been definitively associated with diseases of the skin, most commonly in immunocompromised individuals. MCPyV is a predominant aetiology in Merkel cell carcinomas. TSPyV is one of the aetiological factors of trichodysplasia spinulosa. HPyV6 and HPyV7 have been recently linked to pruritic skin eruptions. The roles of HPyV9, HPyV10 and HPyV13 in pathogenesis, if any, are still unknown, but their molecular features have provided some insight into their functional biology. RESULTS In this review, we summarize the known molecular mechanisms, clinical presentation and targeted therapies of each of the eight cutaneous HPyVs. CONCLUSIONS We hope that heightened awareness and clinical recognition of HPyVs will lead to increased reports of HPyV-associated diseases and, consequently, a more robust understanding of how to diagnose and treat these conditions.

Abstract
The name of the family Polyomaviridae, derives from the early observation that cells infected with murine polyomavirus induced multiple (poly) tumors (omas) in immunocompromised mice. Subsequent studies showed that many members of this family exhibit the capacity of mediating cell transformation and tumorigenesis in different experimental models. The transformation process mediated by these viruses is driven by viral pleiotropic regulatory proteins called T (tumor) antigens. Similar to other viral oncoproteins T antigens target cellular regulatory factors to favor cell proliferation, immune evasion and downregulation of apoptosis. The first two human polyomaviruses were isolated over 45 years ago. However, recent advances in the DNA sequencing technologies led to the rapid identification of additional twelve new polyomaviruses in different human samples. Many of these viruses establish chronic infections and have been associated with conditions in immunosuppressed individuals, particularly in organ transplant recipients. This has been associated to viral reactivation due to the immunosuppressant therapy applied to these patients. Four polyomaviruses namely, Merkel cell polyomavirus (MCPyV), Trichodysplasia spinulosa polyomavirus (TSPyV), John Cunningham Polyomavirus (JCPyV) and BK polyomavirus (BKPyV) have been associated with the development of specific malignant tumors. However, present evidence only supports the role of MCPyV as a carcinogen to humans. In the present review we present a summarized discussion on the current knowledge concerning the role of MCPyV, TSPyV, JCPyV and BKPyV in human cancers.

Abstract
BACKGROUND Trichodysplasia spinulosa (TS) is a disfiguring folliculocentric cutaneous disease caused by infection with the trichodysplasia spinulosa polyomavirus (TSPyV). The TSPyV genome contains splice variants encoding the middle tumour (mT) antigen, although the potential role for TSPyV mT antigen in disease development remains unknown. OBJECTIVE The current study was designed to investigate the mechanistic properties of TSPyV mT antigen, which may further our understanding of TS pathogenesis and provide insight into potential therapies. METHODS A lentiviral packaging system was used to create an inducible cell line expressing TSPyV mT antigen. Proteins were extracted, separated by SDS-PAGE and subjected to Western blot analysis. Co-immunoprecipitation experiments and mutational analyses were also performed to evaluate protein-protein interactions of mT antigen. RESULTS We describe a novel mechanism of action for mT antigen that involves hyperactivation of MEK, ERK and MNK1. Our findings suggest that dysregulation of these key signalling molecules depends upon TSPyV mT antigen interaction with protein phosphatase 2A (PP2A) via intact Zn binding motifs. CONCLUSION Given that PP2A interaction and MEK/ERK/MNK1 phosphorylation are associated with high levels of cell proliferation and inflammation, our findings provide new evidence that TSPyV mT antigen may contribute to the pro-proliferative conditions that lead to TS development.
