TCR repertoire of CD8+ T cells in murine lymphocytic choriomeningitis virus infection

Many characteristics of persistent viral infections in humans (e.g. HIV, HCV, or HBV) are also observed during chronic infection of mice with lymphocytic choriomeningitis virus (LCMV). For example, infection with LCMV is associated with a progressive functional impairment and even leads to deletion of the virus-specific CD8+ T cell response. CD8+ T cells play an important role in adaptive immunity against virus-infected cells and tumor cells. Therefore, advancing our understanding of the CD8+ T cell responses may play an important role in controlling infections has important implications for the design of CD8 T cell epitope-based vaccines. The number of unique TCRαβ pairs in naïve T cells is estimated to about 2× 106 in mice. A TCR repertoire is considered more diverse if it contains more V(D)J combinations. Interestingly, studies suggets a compelling evidence of a link between TCR diversity and protection from infection (Messaoudi et al., 2002). TCR repertoires responding to a particular antigenic epitope are distinct between individuals. However, certain viral epitopes have also been shown to recruit preferentially a restricted TCR repertoire and some observations suggests public TCRs in a variety of infectious diseases. Understanding how CD8+ T cells repertoires are selected during differentiation and upon antigenic challenge is important at a therapeutic level for vaccine design and immunotherapy. In this study we analyze the repertoires of CD8+ T cells following LCMV infection. Naïve CD8+ T cells specific for from lymph nodes, spleen and bone marrow were identified directly ex vivo with cognate fluorescent pMHCI tetramers for LCMV epitope GP33 (Price et al., 2005) and then sorted by flow cytometry for TRBV13. Following, deep sequencing by multiplex single-nested PCR and direct sequencing of PCR products.
