Candida albicans recognition receptors

Candida albicans recognition receptors represent a complex network of immune sensors that identify fungal cell wall components and proteins to initiate a host defense. This group includes innate pattern recognition receptors (PRRs) such as Dectin-1 (CLEC7A), which binds beta-1,3-glucans, and Dectin-2 (CLEC6A) and Mincle (CLEC4E), which recognize alpha-mannans (Gow et al., 2012, Nature Reviews Microbiology). Toll-like receptors, specifically TLR2 and TLR4, also contribute by sensing phospholipomannans and O-linked mannans (Netea et al., 2008, Trends in Immunology). Furthermore, the adaptive immune system utilizes B-cell receptors (BCRs) and T-cell receptors (TCRs) to recognize specific fungal epitopes like the Als3 adhesin, which is a primary target for vaccine development (Edwards et al., 2018, Clinical Infectious Diseases). These receptors collectively orchestrate phagocytosis, the respiratory burst, and the secretion of critical cytokines such as IL-6, IL-23, and IL-17, which are vital for clearing fungal infections. Therapeutic strategies targeting these receptors include immunomodulators like beta-glucans and vaccines designed to enhance protective Th1/Th17 responses in immunocompromised individuals.
