Abstract
- We have generated a hamster anti-mouse class I reactive mAb that is capable of activating T cells in the presence of the cofactor PMA, as assayed by both IFN-gamma production and cellular proliferation. This mAb detects an epitope present on the majority of murine class I molecules, with the known exceptions of H-2Kk and H-2Kq, and is therefore not beta 2-microglobulin-specific. It also recognizes multiple human class I molecules. The epitope recognized by this antibody maps to the class I alpha 1 domain. The activation properties of this mAb are not mediated exclusively through the glycosylphosphatidylinositol-linked Qa-2 molecule, as the antibody activates spleen cells from Qa-2 negative strains. Although class I molecules are not usually considered as activation Ag, these data demonstrate their potential for involvement in signal transduction.
