title: Modulation of T lymphocyte function by the angiogenesis inhibitor AGM-1470.
abstract: The angiogenesis inhibitor AGM-1470 has recently been reported to inhibit collagen-induced arthritis in rats. To determine if the anti-arthritic effects of AGM-1470 might be due to T cell inhibition, we have studied its effects on T cell responses in vitro. Responses of human cells to tetanus toxoid (TT), and those of murine splenocytes to staphylococcal enterotoxin (SE), mitogens or a mls difference were inhibited by AGM-1470. Responses of human cells to SE, OKT3 and PHA were all partially inhibited on day 2 (d2) but not d3, and in fact were augmented on d6-8. The amount of IL-2 in SEA cultures was augmented on d4 and d5. There were no differences in the expression of CD3, CD4, CD8, CD25, CD45RA, CD45RO, LFA-1, VLA-4 or VLA-6 in inhibited cultures, except for slight decreases in CD25 and CD45RO in TT cultures. These results indicated that the angiogenesis inhibitor AGM-1470 also modulates human and murine lymphocyte function.
