Chorionic gonadotropin alleviates thioglycollate-induced peritonitis by affecting macrophage function.

abstract：:An understanding of the binding specificity of leukocyte integrins is important to determine the range of ligands that interact with these receptors during inflammatory processes. In this study we show that the alpha4beta1 integrin can interact with casein and denatured albumin and promote leukocyte adhesion through t...
