| Popis: | Monoclonal antibody RR 1/1 directed against the putative LFA-1 ligand molecule intracellular adhesion molecule-1 (ICAM-1) was found to inhibit the T cell proliferative response to the antigen PPD. Interestingly, the percentage of unstimulated monocytes which expressed ICAM-1 on their surface appeared to vary greatly from person to person although the majority of monocytes did express high levels of ICAM-1 within their cytoplasm and surface expression could be rapidly induced on most cells by adherence to fibronectin. Resting T cells showed no evidence of surface or cytoplasmic ICAM-1 although expression was induced both within the cell and on the membrane as a result of activation with phytohemagglutinin or a combination of OKT3 and phorbol 12,13-dibutyrate. The significance of these findings with respect to the function of monocyte and T cell in the generation of an immune response is discussed. |
