Immunity to mycobacteria: possible role of alpha/beta and gamma/delta T lymphocytes.
Immunity to pathogenic mycobacteria is mediated by T lymphocytes. The possible contribution of CD4 alpha/beta T cells, CD8 alpha/beta T cells and gamma/delta T cells as well as the possible role of interleukin-mediated macrophage activation and target cell lysis through direct cell contact is discussed. Furthermore, attempts to define mycobacterial antigens for T lymphocytes with particular emphasis on heat shock proteins are described. The data currently available suggest complex interactions between different T-cell types in immunity to mycobacteria.
