Research progress in the role of glucose-regulated protein 78 in mucormycosis / 中华微生物学和免疫学杂志

ABSTRACT

Mucormycosis is an infectious disease characterized by rapidly progressive vascular invasiveness, thrombosis and tissue necrosis, which could be potentially responsible for blocking the exudation of leukocytes to infection sites and affecting drug distribution. Glucose-regulated protein 78 (GRP78) is a key protein involved in regulating the invasiveness of Mucorales. Endoplasmic reticulum GRP78 is overexpressed under various stress conditions and transported to the cell membrane to become a cell surface receptor for Mucorales entering into vascular endothelial cells. This article reviewed the mechanisms and pathogenesis of GRP78-mediated host cell invasion and summarized the progress in related targeted drugs, aiming to provide reference for developing multi-target intervention against mucormycosis.
