Histamine 79-88 PCNA clamp associated factor Homo sapiens 8-11 2043925-16 1991 Our studies indicate that: (a) adherence of neutrophils to endothelial cells induced by histamine and thrombin is mediated by PAF production since PAF antagonists inhibited the adherence of neutrophils; and (b) neutrophils, not endothelial cells, are the target cells through which dexamethasone acts to inhibit adherence. Histamine 88-97 PCNA clamp associated factor Homo sapiens 126-129
