title: CTL recognize different determinants from those defined serologically on Ld somatic cell mutants.
abstract: Reciprocal Ld structural mutants have been isolated from a somatic cell line. Testing of allogeneic CTL clones on these mutants suggests that the majority of CTL clones recognize determinants different from those that elicit antibody production. Of 36 CTL clones tested, only three clones appeared to recognize a determinant that was related to the negatively selected serologic determinant. However, mAb blocking studies suggest that inhibition of CTL activity by anti-H-2 mAb does not necessarily reflect the fine specificity of the CTL activity.
