Megjegyzések:	Costimulatory molecules in addition to occupancy of the T-cell antigenreceptor, are required to induce T-cell proliferation.Previous worksuggested that membrane molecules responsible for costimulatoryactivity were not constitutively expressed on the antigen presenting cell(APC) surface. In the present study, we have identified a clonedmacrophage cell line (FLJ2) with inducible APC function. Theunactivated FLJ2 line could not induce T-cell proliferation. FLJ2 couldpresent alloantigen, and stimulate proliferation of either a T-cell clone ornormal resting T cells following activation with IFN y or unexpectedlywith lipopolysaccaride (LPS)-Activated FLJ2 cells could be fixed andAPC function was preserved. The relevant inducible molecules requiredfor APC function appeared distinct from la and IL1. The expression ofICAM-1 and LFA-1 was increased during activation and anti-LFA-1 antibody blocked APC function. This suggests that one important featureof the activation process may be improvement of cellular adhesion.

Cím:	Growth of immature (double negative) rat thymocytes in the presence of IL-1 / Walter H. Gotlieb, Laszlo Takacs, Howard A. Young, Luca Gusella, Scott K. Durum
Dátum:	1990
Megjegyzések:	t is unclear which growth factors, if any, are involved in the growth and differentiation of immature T cells in the thymus. Because IL-1 has been previously implicated in thymocyte proliferation, we examined the effects of IL-1 on precursor thymocytes, the CD4-CD8- or double-negative (DN) cells. We show that IL-1 (together with Con A) is a growth factor for DN, TCR- alpha beta-cells in vitro. After 5 days of culture in IL-1 and Con A, a number of phenotypic changes were observed and two subsets of DN cells were distinguished. One subset expressed full length TCR-alpha and -beta mRNA and surface alpha beta TCR, the other expressed low levels of full length TCR-gamma together with high levels of full length TCR-delta mRNA. Thus, DN cells are induced by IL-1 and Con A to proliferate and express TCR without parallel acquisition of CD4 or CD8 markers. These data suggest that IL-1 drives early steps of intrathymic T cell differentiation.
