Alpha 4 integrin-dependent leukocyte recruitment does not require VCAM-1 in a chronic model of inflammation.

Abstract

Rats immunized with Mycobacterium butyricum in Freund's adjuvant develop a chronic vasculitis, with large increases in leukocyte rolling and adhesion in mesenteric postcapillary venules that are significantly inhibited with an alpha 4 integrin Ab. Using intravital microscopy to visualize chronically inflamed microvessels, we demonstrated that alpha 4… (More)
