Dynamics of T Cell Dysfunction in Primary

Award amount: 40,000.00

We propose that during the evolution of primary HIV-1 infection an expansion in the proportion of CD8 T cells expressing the inhibitory receptor, Tim-3, will result in failure to control viral replication. In those who initiate HAART we predict they will experience greater declines in Tim-3 expression. Accordingly, over a one year timeline, the approach will involve the use of sophisticated multiparameteric flow cytometry to assess the phenotype and function of such a CD8 T cell repertoire and assess for statistical significant differences between and within subjects.
