Cross-recognition of N-formylmethionine peptides is a general characteristic of H2-M3-restricted CD8+ T cells

Infect Immun. 2005 Jul;73(7):4423-6. doi: 10.1128/IAI.73.7.4423-4426.2005.

Abstract

H2-M3-restricted CD8+ T cells can exhibit cross-reactivity to different bacterially derived N-formylmethionine peptides. The extent of this promiscuity is unclear. We deleted the nonredundant fMIVTLF epitope and found that Listeria monocytogenes still primed fMIVTLF-specific T cells. Thus, cross-reactivity appears to be a more general characteristic of H2-M3-restricted T cells.
