Reports from Louisiana State University add new data to research in thrombosis

"T-lymphocytes and interferon-gamma (IFN-gamma) contribute to leukocyte recruitment in postcapillary venules during hypercholesterolemia. Our objectives were to determine whether: (1) T-lymphocytes are the source of this IFN-gamma, and (2) whether T-cell-derived IFN-gamma also mediates the accompanying arteriolar dysfunction and platelet adhesionIntravital videomicroscopy was used to quantify arteriolar responses to acetylcholine, and leukocyte and platelet adhesion in postcapillary venules of wild-type (WT), immunodeficient (SCID), and IFN-gamma(-/-) mice on a normal (ND) or high-cholesterol (HC) diet," scientists in the United States report.

"Acetylcholine-induced...
