cytotoxic T lymphocyte-associated molecule-4 (CTLA-4)

Biology; Immunology

The high-affinity receptor for B7 molecules expressed on T cells.

cyclophosphamide

Biology; Immunology

An immunosuppressive drug that is more toxic for B than for T lymphocytes. Consequently, it is a more effective suppressor of humoral antibody synthesis than of cell-mediated ...

cyclosporin A

Biology; Immunology

An immunosuppresive drug that inhibits signaling from the T-cell receptor, preventing T-cell activation and effector function. It binds to cyclophilin, and this complex binds to ...

cytokine receptors

Biology; Immunology

Cellular receptors for cytokines. Binding of the cytokine to the cytokine receptor stimulates signal transduction resulting in new activities in the cell, such as growth, ...
