B-lymphocyte responses to trinitrophenyl-conjugated Ficoll: requirement for T lymphocytes and Ia-bearing adherent cells.
These studies were done to characterize the cellular requirements for B-lymphocyte responses to the haptenated polysaccharide trinitrophenyl-conjugated Ficoll. By using an in vitro microculture system, it was demonstrated that hapten-specific anti-trinitrophenyl-conjugated Ficoll plaque-forming cell responses by B lymphocytes require Ia-bearing adherent accessory cells and Thy 1+ Lyt 1+2- nylon...
متن کاملCytotoxic T lymphocytes induced against allogeneic I-region determinants react with Ia molecules on trinitrophenyl-conjugated syngeneic target cells
The major histocompatibility complex codes for determinants which are recognized by and serve as targets for cytolytic T lymphocytes (CTL) (1). Antigens coded for by the K and D loci of the H-2 complex can activate xenogeneic or allogeneic CTL (2,3). In addition, the H-2K or H-2D gene products function as those molecules against which syngeneic CTL responses specific for chemical, viral, and mi...
متن کاملMajor histocompatibility complex-restricted self-recognition in responses to trinitrophenyl-ficoll. Adaptive differentiation and self- recognition by B cells
The present study has examined the possibility of TNP-Ficoll-responsive B cells recognize the MHC determinants expressed by the accessory cells with which they interact for the generation of T cell-independent responses to "high" concentrations (10(-2) micrograms/ml) of TNP-Ficoll. In experiments with B cells from normal mice, it was found that MHC homology between the TNP-Ficoll-responsive B c...
متن کاملRequirement for deoxycytidine kinase in T and B lymphocyte development.
Deoxycytidine kinase (dCK) is a rate-limiting enzyme in deoxyribonucleoside salvage, a metabolic pathway that recycles products of DNA degradation. dCK phosphorylates and therefore activates nucleoside analog prodrugs frequently used in cancer, autoimmunity, and viral infections. In contrast to its well established therapeutic relevance, the biological function of dCK remains enigmatic. Highest...
متن کاملGenetic control of cytolytic T-lymphocyte responses. I. Ir gene control of the specificity of cytolytic T-lymphocyte responses to trinitrophenyl-modified syngeneic cells
The ability of cytotoxic T lymphocytes (CTL) induced in vitro to trinitrophenyl (TNP)-modified syngeneic cells to cross-reactively lyse a TNP allogeneic spleen target varies among inbred mouse strains. The cross-reactive CTL phenotype was found to be histocompatibility 2 (H-2) linked and to be dominant in F1 hybrid mice. All strains investigated demonstrated cross-reactivity except for some str...
