This article provides a review of studies evaluating the role of host (and viral) genetics (including variation in HLA genes) in the immune response to coronaviruses, as well as the clinical outcome of coronavirus-mediated disease. The initial sections focus on seasonal coronaviruses, SARS-CoV, and MERS-CoV. We then examine the state of the knowledge regarding genetic polymorphisms and SARS-CoV-2 and COVID-19. The article concludes by discussing research areas with current knowledge gaps and proposes several avenues for future scientific exploration in order to develop new insights into the immunology of SARS-CoV-2.

MicroRNAs (miRNAs) and transfer RNA-derived stress-induced RNAs (tiRNAs) have emerged as crucial players in the post-transcriptional regulation of gene expression in various cellular processes, including immunity and host defense against infections. In recent years, increasing evidence has highlighted their complex role in influencing the host response during viral and bacterial infections. miRNAs have been shown to play multiple roles in host-pathogen interaction like TLR activation and altered disease virulence during bacterial infections.

Verona-integron-metallo-β-lactamase (VIM-2) is one of the most widespread class B β-lactamase responsible for β-lactam resistance. Although active-site residues help in metal binding, the residues nearing the active-site possess functional importance. Here, to decipher the role of such residues in the activity and stability of VIM-2, the residues E146, D182, N210, S207, and D213 were selected through in-silico analyses and substituted with alanine using site-directed mutagenesis.

Background: In holobiont, microbiota is known to play a central role on the health and immunity of its host. Then, understanding the microbiota, its dynamic according to the environmental conditions and its link to the immunity would help to react to potential dysbiosis of aquacultured species. While the gut microbiota is highly studied, in marine invertebrates the hemolymph microbiota is often set aside even if it remains an important actor of the hemolymph homeostasis.

Whether the fat-soluble vitamins A, D, E, and K are associated with development of graft-versus-host disease (GvHD) after allogeneic stem cell transplantation, is unclear. We assessed if the levels of these vitamins were associated with development of GvHD during the first year after transplantation using data from a two-armed randomized nutritional intervention trial. Changes in plasma levels during 1-year follow-up were analyzed using a linear mixed model for repeated measurements.

Human T-lymphotropic virus-1 (HTLV-1) induces neoplastic adult T-cell leukemia/lymphoma (ATLL) and neurological HTLV-1 associated myelopathy (HAM) in approximately 3%-5% of infected individuals. The precise factors that facilitate disease manifestation are still unknown; interaction between the virus and the host's immune response is key. Cytokines regulates physiological activities and their dysregulation may initiate the pathogenesis of various malignant and infectious diseases.
