Project description:We performed whole transcriptome analysis of the ampullae, the primary site of EAV persistence, derived from long-term carrier stallions to understand the molecular signature of persistent infection. We demonstrated that long-term persistence is characterized by a local CD8+ T lymphocyte response predominantly driven by the transcription factors EOMES and NFATC2.We showed that EAV persistence is associated with an enhanced expression of CXCL16/CXCR6 in infiltrating lymphocytes. Furthermore, we established a link between the CXCL16 genotype and the gene expression profile at the site of persistence following EAV infection. Co-expression network analysis identified CXCL16 as a “hub” gene, likely driving a specific transcriptional network.
Project description:Transcriptional profiling from adult Scyliorhinus retifer from electrosensory cells of the ampullae of Lorenzini, forebrain, skin, and skeletal muscle shows differential gene expression of voltage-activated ion channels related to sensory transduction.
