transcriptional profiles of california sea lion peripheral nk and cd 8 t cells reflect ecological regionalization and infection by Oncogenic Viruses
Frontiers in Immunology, 2019Co-Authors: Ignacio Penin, Karina Acevedowhitehouse, Adriana Floresmoran, Monica Eugenia Figueroacabanas, Fabiola Guerrerode La Rosa, Luis A Sotogarcia, Roberto AlvarezmartinezAbstract:The California sea lion is one of the few wild mammals prone to develop cancer, particularly urogenital carcinoma (UGC), whose prevalence is currently estimated at 25% of dead adult sea lions stranded along the California coastline. Genetic factors, Viruses and organochlorines have been identified as factors that increase the risk of occurrence of this pathology. Given that no cases of UGC have as yet been reported for the species along its distribution in Mexican waters, the potential relevance of contaminants for the development of urogenital carcinoma is highlighted even more as blubber levels of organochlorines are more than two orders of magnitude lower in the Gulf of California and Mexican Pacific than in California. In vitro studies have shown that organochlorines can modulate anti-viral and tumor-surveillance activities of NK and cytotoxic T-cells of marine mammals, but little is known about the activity of these effectors in live, free-living sea lions. Here, we examine leukocyte transcriptional profiles of free-ranging adult California sea lions for eight genes (Eomes, Granzyme B, Perforin, Ly49, STAT1, Tbx21, GATA3, and FoxP3) selected for their key role in anti-viral and tumor-surveillance, and investigate patterns of transcription that could be indicative of differences in ecological variables and exposure to two Oncogenic Viruses: sea lion type one gammaherpesvirus (OtHV-1) and sea lion papillomavirus type 1 (ZcPV-1) and systemic inflammation. We observed regional differences in the expression of genes related to Th1 responses and immune modulation, and detected clear patterns of differential regulation of gene expression in sea lions infected by genital papillomavirus compared to those infected by genital gammaherpesvirus or for simultaneous infections, similar to what is known about herpesvirus and papillomavirus infections in humans. Our study is a first approach to profile the transcriptional patterns of key immune effectors of free-ranging California sea lions and their association with ecological regions and Oncogenic Viruses. The observed results add insight to our understanding of immune competence of marine mammals, and may help elucidate the marked difference in the number of cases of urogenital carcinoma in sea lions from US waters and other areas of their distribution.

inherited interleukin 2 inducible t cell itk kinase deficiency in siblings with epidermodysplasia verruciformis and hodgkin lymphoma
Clinical Infectious Diseases, 2019Co-Authors: Leila Youssefian, Hassan Vahidnezhad, Mehdi Yousefi, Amir Hossein Saeidian, Arghavan Azizpour, Andrew TouatiAbstract:Biallelic mutations in the ITK gene cause a T-cell primary immunodeficiency with Epstein-Barr virus (EBV)-lymphoproliferative disorders. We describe a novel association of a homozygous ITK mutation with β-human papillomavirus (HPV)-positive epidermodysplasia verruciformis. Thus, loss of function in ITK can result in broad dysregulation of T-cell responses to Oncogenic Viruses, including β-HPV and EBV.
