Conventional CD4+ T cells present bacterial antigens to induce cytotoxic and memory CD8+ T cell responses

Antigen presentation is generally considered the domain of innate immune cells, but CD4+ T cells can transphagocytose bacteria from infected dendritic cells. Here the authors show CD4+ T cells can transphagocytose bacterial and tumour antigens and present them to CD8+ T cells to activate memory and...

Sumario:Antigen presentation is generally considered the domain of innate immune cells, but CD4+ T cells can transphagocytose bacteria from infected dendritic cells. Here the authors show CD4+ T cells can transphagocytose bacterial and tumour antigens and present them to CD8+ T cells to activate memory and cytotoxic functions.
