| Popis: | The role of lymphocyte function-associated antigen 1 (LFA-1) in human T cell chemotaxis was investigated by using mAb specific to the beta-chain (TS1/18) (CD18) and alpha-chain (TS1/22) (CD11a) of LFA-1. T cell chemotaxis in response to IL-2 and to lymphocyte chemotactic factor (LCF) was markedly suppressed by the addition of TS1/18. TS1/22 was a less effective inhibitor than TS1/18 with only LCF stimulated responses showing significant inhibition when compared in seven different T cell preparations. Neither TS1/18 nor TS1/22 antibody inhibited random T cell migration. Control mAb to CD4 T cells failed to inhibit T cell random migration or chemotaxis. Additional studies to evaluate the adherence and migration of T cells through IL-1-stimulated human umbilical vein endothelial cell (HUVEC) monolayers showed that both TS1/22 and TS1/18 suppressed T cell migration through HUVEC, but failed to inhibit adherence of T cells to these cells. These studies indicate that LFA-1 plays a role in the migration of T cells through HUVEC and in the in vitro chemotactic response of T lymphocytes to IL-2 and LCF. |
