MEMORY T CELLS IN LATENT MYCOBACTERIUM TUBERCULOSIS INFECTION ARE DIRECTED AGAINST THREE ANTIGENIC ISLANDS AND LARGELY CONTAINED IN A CXCR3+CCR6+ TH1 SUBSET.

Memory T cells in latent Mycobacterium tuberculosis infection are directed against three antigenic islands and largely contained in a CXCR3+CCR6+ Th1 subset.

An understanding of the immunological footprint of Mycobacterium tuberculosis (MTB) CD4 T cell recognition is still incomplete.Here we report that human Th1 cells specific Tissues for MTB are largely contained in a CXCR3(+)CCR6(+) memory subset and highly focused on three broadly immunodominant antigenic islands, all related to bacterial secretion
