Researchers reported that TREM2-positive macrophages detect candidalysin to trigger an early antifungal immune response during oropharyngeal candidiasis. The work, led by Yunsheng Liang at Central South University’s Second Xiangya Hospital with collaborators including Yingping Xu at Southern Medical University and Xiaowen Wang at Peking University First Hospital, was published in Immunity & Cell Biology-linked venue details and describes a previously underappreciated innate sensing mechanism. By identifying candidalysin as a trigger and TREM2+ macrophages as key responders, the study refines the understanding of how the oral mucosal immune system mounts fast protection against Candida. The findings also provide a potential target path for therapies designed to modulate early innate immune activation rather than relying solely on later-stage antifungal mechanisms. For biotech, the study supports continued interest in immune-pathway therapeutics in infectious disease where resistance and tolerability pressures complicate conventional antimicrobial development.
