摘要
Candida albicans is an opportunistic pathogen and is recognised and phagocytosed by macrophages. Using live-cell imaging, non-lytic expulsion/exocytosis of C. albicans from macrophages is demonstrated for the first time. Following complete expulsion, both the phagocyte and pathogen remain intact and viable. Partial engulfment of hyphal C albicans without macrophage lysis is also demonstrated. These observations underpin the complexity of interactions between C. albicans and innate immune cells. (C) 2012 Elsevier Inc. All rights reserved.
