Abstract
Viral infections have been frequently associated with physiological and pathological changes in the endocrine system for many years. The numerous early and late endocrine complications reported during the current pandemic of coronavirus disease 2019 (COVID-19) reinforce the relevance of improving our understanding of the impact of viral infections on the endocrine system. Several viruses have been shown to infect endocrine cells and induce endocrine system disturbances through the direct damage of these cells or through indirect mechanisms, especially the activation of the host antiviral immune response, which may lead to the development of local or systemic inflammation or organ-specific autoimmunity. In addition, endocrine disorders may also affect susceptibility to viral infections since endocrine hormones have immunoregulatory functions. This review provides a brief overview of the impact of viral infections on the human endocrine system in order to provide new avenues for the control of endocrine diseases.

Abstract
CONTEXT The origin of Graves disease (GD) remains elusive. However, evidence of an association between GD and viral infections is emerging. Human leukocyte antigen (HLA) class I presents viral antigens to circulating immune cells and plays a crucial role in the defense against viral infections. OBJECTIVE This work aimed to investigate HLA class I expression, enterovirus presence, and the viral immune response proteins signal transducer and activation of transcription 1 (STAT1) and protein kinase R (PKR) in thyroid tissue from GD patients. METHODS We collected thyroid tissue from core needle biopsies or surgical specimens from 48 GD patients and 24 controls. Standard immunohistochemistry was used to detect HLA class I and enteroviral capsid protein 1 (VP1) on formalin-fixed and paraffin-embedded tissue. STAT1 and PKR were examined by combined immunofluorescence staining. HLA class I expression score was the main outcome measure. RESULTS The HLA class I expression score, which takes both proportion and intensity of immunostaining into account, was significantly higher in GD patients (3.1 ± 3.3) than in controls (0.5 ± 0.9) (P < .001). Significantly more VP1 positive thyroid cells were found GD samples (50.1 ± 30.5%) than in controls (14.9 ± 10.5%) (P < .001). STAT1 and HLA class I were found within the same thyroid cells and PKR and VP1 were also colocalized within thyroid cells. CONCLUSION HLA class I is upregulated in GD and enterovirus protein is prevalent in thyroid tissue. The colocalization of HLA class I with STAT1 and VP1 with PKR indicates an antiviral tissue response. These findings support the concept of a link between viral infections and GD.

Abstract
Background: Hashimoto's thyroiditis (HT) is a common autoimmune disease of unknown origin. However, viral infections have been implicated as triggers for autoimmunity. Human leukocyte antigen (HLA) class I presents antigens to circulating immune cells and plays a crucial role in the defense against viral infections. This study aimed to investigate the presence of enterovirus and HLA class I expression in one of the largest HT thyroid tissue cohorts to date. In addition, viral receptors and viral immune response proteins were examined. Methods: Thyroid tissue samples from 46 HT patients were obtained using core needle biopsy. Thyroid tissue collected during neck surgery for other reasons than thyroid autoimmunity served as controls. Standard immunohistochemistry on formalin-fixed, paraffin-embedded tissue samples were used to detect HLA class I, enteroviral capsid protein 1 (VP1), and coxsackie and adenovirus receptor (CAR) in thyroid cells. A subset of the samples was examined with combined immunofluorescence staining for signal transducer and activator of transcription 1 (STAT1) and protein kinase R (PKR). Results: Significantly more HLA class I-positive samples were found in the HT group (31 out of 46 [67.4%]) than in the control group (5 out of 24 [20.8%]) (p < 0.001). Moreover, the semiquantitative score assessing the grade of HLA class I expression was significantly higher in the HT group (3.9 ± 3.1) than in the control group (0.5 ± 0.9) (p < 0.001). In addition, STAT1 was colocalized with HLA class I, and PKR and VP1 were also found and were colocalized together. VP1 was detected in both controls and the HT samples, with slightly more VP1+ thyroid cells in the HT samples (20.1% ± 16.4%) than in controls (14.9% ± 10.5%). Finally, the presence of CAR in thyroid cells was confirmed. Conclusion: The current study confirmed that HLA class I hyperexpression is a defining feature of HT. Thyroid cells express CAR, thus making them susceptible to enterovirus infection. The colocalization of HLA class I with STAT1 and VP1 with PKR indicates an intracellular, antiviral host response. These findings support the concept of a firm link between viral infection and autoimmune thyroid diseases.

Abstract
The role of enteroviruses, especially Coxsackievirus B (CVB), in type 1 diabetes is suspected, but the mechanisms of the virus-induced or aggravated pathogenesis of the disease are unknown. The hypothesis of an enterovirus-induced disturbance of pancreatic β-cells regeneration has been investigated in the human system. The infection of human pancreas ductal cells and pancreatic duct cell line, PANC-1, with CVB4E2 has been studied. Primary ductal cells and PANC-1 cells were infectable with CVB4E2 and a RT-PCR assay without extraction displayed that a larger proportion of cells harbored viral RNA than predicted by the detection of the viral capsid protein VP1 by indirect immunofluorescence. The detection of intracellular positive- and negative-strands of enterovirus genomes in cellular extracts by RT-PCR and the presence of infectious particles in supernatant fluids during the 37 weeks of monitoring demonstrated that CVB4E2 could persist in the pancreatic duct cell line. A persistent infection of these cells resulted in an impaired expression of Pdx1, a transcription factor required for the formation of endocrine pancreas, and a disturbed formation of islet-like cell aggregates of which the viability was decreased. These data support the hypothesis of an impact of enteroviruses onto pancreatic ductal cells which are involved in the renewal of pancreatic β-cells.

Abstract
BACKGROUND The role of viruses as environmental triggers for Hashimoto's thyroiditis (HT) is controversial. Thyroid epithelial cells express a variety of molecules involved in antiviral responses. This study combined histological, immunological, and virological tests to describe changes in tissue from patients with newly diagnosed and untreated HT. To study the early events, patients with positive thyroid peroxidase antibodies (TPO-Ab) and normal thyroid function were also included. This stage was defined as "prethyroiditis." METHODS Thyroid tissue was collected from 47 patients with high titers of TPO-Ab and from 24 controls. Seventeen patients had prethyroiditis, 17 had subclinical hypothyroidism, and 13 had overt hypothyroidism. The interferon (IFN)-α/β-inducible myxovirus resistance protein 1 (myxovirus resistance protein A; MxA) was used as a surrogate marker for type I IFN expression. Inflammation, expression of MxA, and the presence of the enteroviralcapsid protein (VP1) were characterized by immunohistochemistry. The presence of enterovirus (EV) RNA was examined by in situ hybridization. RESULTS The density of CD4+ T cells was increased in all three patient groups, while CD8+ T cells were increased only in patients with overt hypothyroidism. The density of plasma cells increased as the disease progressed. The density of plasmacytoid dendritic cells and the expression of MxA were significantly increased in all patient groups compared with controls (p<0.01). EV RNA was present in 11% of HT patients, but in none of the control subjects, whereas the enteroviral protein was detected in 19% and 16%, respectively. CONCLUSION The inflammatory reaction in the thyroid gland is a very early event in the pathogenesis of HT. The increased expression of MxA in the inflamed tissue suggests that type I IFN plays a role in disease development. Whether this is virus-dependent needs to be explored in further studies.

Abstract
The etiology and pathogenesis of Graves' disease (GD) are still unknown, although it is thought that both genetic and environmental factors are important. Some indirect evidence implies that a viral infection may be a possible etiologic factor in autoimmunity. The main objective of this study was to examine direct evidence of the presence of enteroviruses (EVs) in the thyroid tissue of patients with GD. Thyroid tissue from 22 patients with newly diagnosed GD was obtained by core needle biopsy, while tissue from 24 patients with chronic GD and 24 control subjects without any autoimmune thyroid diseases was collected during neck surgery. Formalin-fixed, paraffin-embedded thyroid tissue samples were examined for the presence of enterovirus capsid protein using immunohistochemistry and for enterovirus RNA using in situ hybridization. Enterovirus capsid protein was detected in 17 (37%) patients and in 4 (17%) control subjects (P = 0.103). Enterovirus RNA was identified in thyroid tissue from nine (20%) patients, but in none of the control subjects (P = 0.016). Eight (90%) of the nine virus RNA positive patients were also positive for enterovirus protein. This is the first study to analyze thyroid tissue for EVs, including patients with untreated, newly diagnosed GD. The results suggest that EVs are more frequently present in thyroid tissue of patients than controls. Further studies are indicated to explore this association to find out if a low-grade chronic enteroviral infection might be involved in the pathogenesis of GD and if this could offer new therapeutic and preventive opportunities.

Virus-host coevolution in a persistently coxsackievirus B3-infected cardiomyocyte cell line. J Virol 2011; 85:13409-19.

Abstract
Coevolution of virus and host is a process that emerges in persistent virus infections. Here we studied the coevolutionary development of coxsackievirus B3 (CVB3) and cardiac myocytes representing the major target cells of CVB3 in the heart in a newly established persistently CVB3-infected murine cardiac myocyte cell line, HL-1(CVB3). CVB3 persistence in HL-1(CVB3) cells represented a typical carrier-state infection with high levels (10(6) to 10(8) PFU/ml) of infectious virus produced from only a small proportion (approximately 10%) of infected cells. CVB3 persistence was characterized by the evolution of a CVB3 variant (CVB3-HL1) that displayed strongly increased cytotoxicity in the naive HL-1 cell line and showed increased replication rates in cultured primary cardiac myocytes of mouse, rat, and naive HL-1 cells in vitro, whereas it was unable to establish murine cardiac infection in vivo. Resistance of HL-1(CVB3) cells to CVB3-HL1 was associated with reduction of coxsackievirus and adenovirus receptor (CAR) expression. Decreasing host cell CAR expression was partially overcome by the CVB3-HL1 variant through CAR-independent entry into resistant cells. Moreover, CVB3-HL1 conserved the ability to infect cells via CAR. The employment of a soluble CAR variant resulted in the complete cure of HL-1(CVB3) cells with respect to the adapted virus. In conclusion, this is the first report of a CVB3 carrier-state infection in a cardiomyocyte cell line, revealing natural coevolution of CAR downregulation with CAR-independent viral entry in resistant host cells as an important mechanism of induction of CVB3 persistence.
