Major histocompatibility complex restriction of soluble helper molecules in T cell responses to altered self
JM Plate
Evidence for major histocompatibility complex (MHC) restriction of soluble
helper effects was observed in the generation of syngeneic killer T cells
to trinitrophenyl-altered self. Ia-bearing T cells obscure the observation
of such interactions, thus, must be removed to detect MHC restriction of
nonspecific soluble helper factor supernates (HFS). Genetic mapping studies
demonstrated that the strain producing HFS must be compatible in the H-21A
region with the strain utilizing the helper molecules for optimal helper
signals to be delivered.
