Abstract:
We previously demonstrated that Bacillus Calmette-Guerin (BCG) immunization activated D(b) restricted CD8+ cytolytic T lymphocyte (CTL) recognizing target cells incubated with mycobacterial culture filtrate. Here, we show that in vitro restimulation of spleen cells from BCG vaccinated or Mycobacterium tuberculosis infected mice with culture filtrate antigens leads to the appearance of a high percentage of D(b) restricted IFNgamma synthesizing CD8+ T cell blasts. Transporter associated protein-2 mutated RMA-S cells incubated with soluble culture filtrate proteins had their MHC class I D(b) b…
