STING-dependent trained immunity contributes to host defense against Clostridium perfringens infection via mTOR signaling
AbstractClostridium perfringens (C. perfringens) infection is recognized as one of the most challenging issues threatening food safety and perplexing agricultural development. To date, the molecular mechanisms of the interactions betweenC. perfringens and the host remain poorly understood. Here, we show that stimulator of interferon genes (STING)-dependent trained immunity protected againstC. perfringens infection through mTOR signaling. Heat-killedCandida albicans (HKCA) training elicited elevated TNF- α and IL-6 production after LPS restimulation in mouse peritoneal macrophages (PM). Although HKCA-trained PM produced de...

Mechanisms of Intestinal Epithelial Cell Damage by Clostridium perfringens
Anaerobe. 2024 Apr 10:102856. doi: 10.1016/j.anaerobe.2024.102856. Online ahead of print.ABSTRACTClostridium perfringens, a Gram-positive bacterium, causes intestinal diseases in humans and livestock through its toxins, related to alpha toxin (CPA), beta toxin (CPB), C. perfringens enterotoxin (CPE), epsilon toxin (ETX), Iota toxin (ITX), and necrotic enteritis B-like toxin (NetB). These toxins disrupt intestinal barrier, leading to various cell death mechanisms such as necrosis, apoptosis, and necroptosis. Additionally, non-toxin factors like adhesins and degradative enzymes contribute to virulence by enhancing colonizati...
