TCR Repertoire Sequencing to Evaluate the Diversity of Follicular Helper T Cells in HIV Infected Lymph Nodes

The TCR repertoire of CD4+ T cells in human lymph nodes is a case-based analysis of the TCR repertoire of CD4+ T cells in human lymph nodes. The study aims to determine how HIV infection alters the repertoire complexity of follicular helper T cells (TFH) in relationship to other T cell subsets in the lymphoid compartment. This study performs TCR repertoire sequencing using Molecular Identifier Clustering-based Immune Repertoire Sequencing (MIDCIRS). We found TFH cells become clonally expanded and convergently selected in LNs from patients with chronic HIV infection.]]>
