Abstract
PURPOSE The SARS-CoV-2 genome has been detected in a variety of human samples including blood, urine, semen, and faeces. However, evidence of virus presence in tissues other than lung are limited. METHODS We investigated whether SARS-CoV-2 could be detected in 50 autoptic specimens of endocrine organs from 29 patients who died of COVID-19. RESULTS The virus was detected in 25 specimens including ten abdominal subcutaneous adipose tissue samples (62%), six testes (67%), and nine thyroid (36%) samples. The analysis of multiple endocrine organ samples obtained from the same patients showed that, in virus-positive cases, the viral genome was consistently detected in all but two matched specimens. CONCLUSION Our findings show that the virus spread into endocrine organs is a common event in severe cases. Further studies should assess the rate of the phenomenon in clinically mild cases. The potential long-term effects of COVID-19 on endocrine functions should be taken into consideration.

Abstract
BACKGROUND A new harmful respiratory disease, called COVID-19 emerged in China in December 2019 due to the infection of a novel coronavirus, called SARS-Coronavirus 2 (SARS-CoV-2), which belongs to the betacoronavirus genus, including SARS-CoV-1 and MERS-CoV. SARS-CoV-2 shares almost 80% of the genome with SARS-CoV-1 and 50% with MERS-CoV. Moreover, SARS-CoV-2 proteins share a high degree of homology (approximately 95%) with SARS-CoV-1 proteins. Hence, the mechanisms of SARS-Cov-1 and SARS-Cov-2 infection are similar and occur via binding to ACE2 protein, which is widely distributed in the human body, with a predominant expression in endocrine tissues including testis, thyroid, adrenal and pituitary. PURPOSE On the basis of expression pattern of the ACE2 protein among different tissues, similarity between SARS-Cov-1 and SARS-Cov-2 and the pathophysiology of COVID-19 disease, we aimed at discussing, after almost one-year pandemic, about the relationships between COVID-19 infection and the endocrine system. First, we discussed the potential effect of hormones on the susceptibility to COVID-19 infection; second, we examined the evidences regarding the effect of COVID-19 on the endocrine system. When data were available, a comparative discussion between SARS and COVID-19 effects was also performed. METHODS A comprehensive literature search within Pubmed was performed. This review has been conducted according to the PRISMA statements. RESULTS Among 450, 100 articles were selected. Tissue and vascular damages have been shown on thyroid, adrenal, testis and pituitary glands, with multiple alterations of endocrine function. CONCLUSION Hormones may affect patient susceptibility to COVID-19 infection but evidences regarding therapeutic implication of these findings are still missing. SARS and COVID-19 may affect endocrine glands and their dense vascularization, impairing endocrine system function. A possible damage of endocrine system in COVID-19 patients should be investigated in both COVID-19 acute phase and recovery to identify both early and late endocrine complications that may be important for patient's prognosis and well-being after COVID-19 infection.

Abstract
The outbreak of coronavirus disease 2019 (COVID-19), caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), is centralizing the interest of the scientific world. In the next months, long-term consequences on the endocrine system may arise following COVID-19. In this article, we hypothesized the effects of SARS-CoV-2 taking into account what learned from the severe acute respiratory syndrome coronavirus (SARS-CoV) that caused SARS in 2003.

Abstract
Intracerebral inoculation of field-isolates as well as established strains of equine herpesvirus-1 (EHV-1) in suckling mice results in viral replication in neurons and glial cells and induces encephalitis. By intraperitoneal (i.p.) inoculation, no histological lesion was observed in the central nervous system (CNS) in suckling mice with the EHV-1 HH1 strain (HH1), whereas a neuroadapted variant (NHH1) produced by serial passage of HH1 in the mouse brain caused severe encephalomyelitis after i.p. inoculation. The purpose of this study was to determine the route of neuroinvasion after i.p. inoculation of NHH1 and to clarify the effects of the brain passage on viral neuroinvasion. NHH1, but not HH1, targeted splenic and pulmonary macrophages and omental fat cells on days 1 and 2 post-inoculation (p.i.). From days 1 to 3 p.i., cell-associated viremia was occurred in NHH1-infected mice, but not in HH1-infected mice. On day 4 p.i., viral antigen was detected in a few endothelial cells, perivascular glial cells and neurons in the CNS in NHH1-infected mice. The number of viral antigen-positive cells increased markedly after day 5 p.i. In contrast, no viral antigen-positive cell was detected in the CNS in HH1-infected mice, except for a few nerve cells in the thoracic cord on day 4 p.i. These results suggest that NHH1 neuroinvasion is hematogenous and is correlated with enhanced extraneural virus growth.

Abstract
African horse sickness virus (AHSV) antigen was demonstrated immunohistochemically in formalin-fixed, paraffin-embedded sections of tissues collected from three ponies suffering from the peracute form of the disease and from one pony affected by the fever form. The pattern of the antigen distribution indicated a particular organ tropism characterised by an accumulation of AHSV antigen in cardio-pulmonary tissues of the animals with the peracute disease and in the spleen of the pony with the fever form. AHSV antigen was identified in endothelial cells of small blood vessels, particularly capillaries and in large mono-nuclear cells resembling macrophages or reticular cells of lymphatic tissues. Occasional circulating mononuclear cells with the morphology of monocytes were also positively stained within the larger vessels. The immunohistochemical results confirm earlier work suggesting that AHSV may have different tropisms to particular organs during various forms of the disease and that different target cell populations exist in vivo. Immunohistochemistry may be an additional useful method for diagnostic and research purposes in AHS.

Abstract
The baculovirus Lymantria dispar nuclear polyhedrosis virus interferes with insect larval development by altering the host's hormonal system. The level of haemolymph ecdysteroids, the insect moulting hormone, was found to be higher in virus-infected larvae than in uninfected controls. This was consistently observed in both fourth instars and day 5-infected fifth instars. The rate of hormone synthesis was examined by in vitro incubation of the prothoracic gland. Gland activity in virus-infected larvae was higher than controls and continued until the late stages of virus infection, even during the time that controls had ceased to secrete ecdysone after moulting. During virus replication, the prothoracic gland was observed to maintain morphological and ultrastructural characteristics indicative of ecdysone biosynthetic activities. Therefore, it is likely that the insects are no longer under the control of the normal hormonal system after virus infection. It is felt that the alteration of hormone titre and the rate of ecdysone synthesis is the result of the activity of ecdysteroid UDP-glucosyl transferase (EGT), a virus-encoded enzyme which is thought to inactivate ecdysteroids by sugar conjugation.

Abstract
Three seronegative sheep persistently infected with Border disease virus and six seropositive, non-viraemic sheep were examined for the cellular distribution of the agent. These animals originated from a closed flock which had been kept in an isolation facility for 5 years. They were killed and immediately necropsied. There were no gross abnormalities other than reduced body weight of the persistently infected sheep. Two samples of each major organ were collected. The first sample was fixed by immersion in formalin and processed for histological examination, which showed no lesions unequivocally attributable to the viral infection. The second sample was snap-frozen for immunohistochemical examination. This revealed viral antigen in all organs of the persistently infected, but in none of the seropositive animals. The infected cells included smooth muscle cells of hollow organs and blood vessels, epithelial cells of the alimentary tract and urogenital organs, lymphocytes in lymphoid organs, endocrine cells, neurons and glial cell.
