title: Analysis of T cell receptor V beta gene usage in primary mixed lymphocyte reactions: evidence for directive usage by different antigen-presenting cells and Mls-like determinants on T cell blasts.
abstract: The usage of four different T cell receptor (TcR) V beta gene families within normal, non-primed T cell populations in response to various types of antigen-presenting cells (APC) in primary mixed lymphocyte reaction has been studied. We demonstrate that distinct patterns of V beta gene usage are obtained within a given T cell population in response to different types of APC with the same allo-H-2. When responder T cells are stimulated with one type of allogeneic APC, from various H-2-disparate mice, the same V beta gene preference is observed. Furthermore, when H-2- and Mls-mismatched APC gene used as stimulators, the Mls-associated V beta 6 and V beta 8.1 gene families are highly elevated in response to both B and T cell blasts from certain Mls-positive strains. The results demonstrate that different types of allogeneic APC have the capacity to generate biases in TcR V beta gene usage and imply that functional Mls-like determinants are presented by T cell blasts. The findings are discussed with respect to TcR-major histocompatibility complex interactions in allostimulation.
