Adhesion of Candida albicans to endothelial cells under physiological conditions of flow.

abstract：:Previous passive antibody transfer experiments have indicated that immunity to a 46-kilodalton membrane glycoprotein (M-2) of Leishmania amazonensis may protect against infection with this parasite. In the studies described in this paper, we investigated the ability of the purified M-2 molecule to elicit a protective ...
