Immunohistochemical studies of c‐reactive protein and apolipoprotein b in inflammatory and arterial lesions

Abstract

Interactions in vivo between C-reactive protein (CRP) and apolipoprotein B (apoB)-containing lipoproteins were sought in inflammatory lesions and atherosclerosis. CRP was demonstrated immunohistochemically on the surface of some muscle fibres in locally induced inflammatory lesions in the rabbit, but apoB was not detected in the same distribution. CRP was not detected in catheter-induced aortic endothelial injuries in the rabbit, in arterial lesions containing apoB from cholesterol-fed rabbits, in apoB-containing human fatty streaks or in advanced human atherosclerotic lesions.
