Induction of cytotoxic T lymphocytes against I-region-coded determinants: in vitro evidence for a third histocompatibility locus in the mouse
H Wagner, D Gotze, L Ptschelinzew and M Rollinghoff
Determinants controlled by the I region of the murine H-2 complex provoked
the generation of cytotoxic T lymphocytes (CTL) in both a secondary and
primary mixed lymphocyte culture. The stimulating determinants appeared to
be controlled by loci within the I-A subregion. The target antigens of the
CTL generated were present on both lipopolysaccharide- and
concanavalin-induced blast lymphocytes, but were barely detectable on
phytohemagglutinin-induced blast cells. The stimulating capacity for CTL
induction of a complete H-2 complex incompatibility by far exceeded the sum
of H-2D/K-region and I-region incompatibility, respectively.
