Deregulated CD8+ T cell cytotoxicity plays a central role in enhancing disease
severity in several conditions. However, we have little understanding of the
mechanisms by which immunopathology develops as a consequence of cytotoxicity.
Using murine models of inflammation induced by the protozoan parasite leishmania,
and data obtained from patients with cutaneous leishmaniasis, we uncovered a
previously unrecognized role for NLRP3 inflammasome activation and IL-1? release
as a detrimental consequence of CD8+ T cell-mediated cytotoxicity, ultimately
resulting in chronic inflammation. Critically, pharmacological blockade of NLRP3
or IL-1? significantly ameliorated the CD8+ T cell-driven immunopathology in
leishmania-infected mice. Confirming the relevance of these findings to human
leishmaniasis, blockade of the NLRP3 inflammasome in skin biopsies from
leishmania-infected patients prevented IL-1? release. Thus, these studies link
CD8+ T cell cytotoxicity with inflammasome activation and reveal novel avenues of
treatment for cutaneous leishmaniasis, as well as other of diseases where CD8+ T
cell-mediated cytotoxicity induces pathology.
