CLEC7A, also known as Dectin-1. is a C-type lectin receptor primarily expressed on immune cells such as macrophages, dendritic cells, and neutrophils. It plays a critical role in innate immunity by recognizing β-glucans, polysaccharide components of fungal cell walls, and certain bacterial pathogens. This receptor is pivotal in initiating immune responses against fungal infections, including Candida and Aspergillus species. Upon ligand binding, CLEC7A activates intracellular signaling pathways, such as the Syk kinase cascade, leading to the production of pro-inflammatory cytokines, reactive oxygen species, and phagocytosis. Its involvement in immune regulation extends to bridging innate and adaptive immunity through T-cell activation and Th17 differentiation.
Recombinant CLEC7A protein is engineered to mimic the native receptor’s functional domains, typically including the extracellular carbohydrate-recognition domain (CRD). Produced in expression systems like mammalian cells or E. coli, it retains ligand-binding specificity, enabling studies on receptor-ligand interactions, immune signaling mechanisms, and host-pathogen dynamics. Researchers use recombinant CLEC7A to explore its therapeutic potential, such as modulating immune responses in fungal infections, autoimmune diseases, or cancer immunotherapy. It also serves as a tool for developing diagnostics or inhibitors targeting β-glucan-mediated pathways. However, challenges remain in optimizing its stability and post-translational modifications to ensure biological relevance in vitro. Overall, CLEC7A recombinant protein is a key reagent for dissecting antifungal immunity and designing novel immunotherapies.
