WebAntigen-specific T cells play a central role in the adaptive immune response and come in a wide range of phenotypes. T cell receptors (TCRs) mediate the antigen-specificities found in T cells. Importantly, high-throughput TCR sequencing provides a fingerprint which allows tracking of specific T cells and their clonal expansion in response to particular antigens. … WebCMV is a common virus that infects people of all ages, regardless of ethnicity or socio-economic class, and most people have been exposed to CMV at some point in their lifetime without their knowledge.
