A Gamma Interferon Independent Mechanism of CD4 T Cell Mediated
Control of Infection
CD4 T cell deficiency or defective IFNγ signaling render humans and mice
highly susceptible to Mycobacterium tuberculosis (Mtb)
infection. The prevailing model is that Th1 CD4 T cells produce IFNγ to
activate bactericidal effector mechanisms of infected macrophages. Here we test
this model by directly interrogating the effector functions of Th1 CD4 T cells
required to control Mtb in vivo. While Th1 CD4 T cells specific for the Mtb
antigen ESAT-6 restrict in vivo Mtb growth, this inhibition is independent of
IFNγ or TNF and does not require the perforin or FAS effector pathways.
Adoptive transfer of Th17 CD4 T cells specific for ESAT-6 partially inhibited
Mtb growth while Th2 CD4 T cells were largely ineffective. These results imply a
previously unrecognized IFNγ/TNF independent pathway that efficiently
controls Mtb and suggest that optimization of this alternative effector function
may provide new therapeutic avenues to combat Mtb through vaccination.
