| lymphocyte specific protein tyrosine kinase p56(lck) | <enzyme> This enzyme is a lymphoid specific src family tyrosine kinase that is critical for T-cell development and activation. Lck is associated with the cytoplasmic domains of CD4, CD8 and the beta-chain of the il-2 receptor, and is thought to be involved in the earliest steps of tcr-mediated T-cell activation. Registry number: EC 2.7.11.- (12 Dec 1998) |
| lymphocyte subsets | A classification of lymphocytes based on structurally or functionally different populations of cells. (12 Dec 1998) |
| lymphocyte transformation | <haematology> The change in morphology and behaviour of lymphocytes exposed to a mitogen or to an antigen to which they have been primed. The result is the production of lymphoblasts, cells that are actively engaged in protein synthesis and that divide to form effector populations. Should not be confused with transformation of the type associated with oncogenic viruses and activation is therefore perhaps a better term. (18 Nov 1997) |
| lymphocyte transfusion | The transfer of lymphocytes from a donor to a recipient or reinfusion to the donor. (12 Dec 1998) |
