Dectin-2-mediated signaling leads to delayed skin wound healing through enhanced neutrophilic inflammatory response and neutrophil extracellular traps formation

Dendritic cell-associated C-type lectin-2 (Dectin-2) recognizes fungal polysaccharides, including α-mannan. Dectin-2-mediated recognition of fungi, such as Candida albicans, leads to NF-κB activation, which induces production of inflammatory cytokines. However, Dectin-2's role in skin wound healing remains unclear. In this study, we sought to determine how Dectin-2 deficiency and the administration of α-mannan affected the wound healing process. Full-thickness wounds were created on the backs of wild type (WT) C57BL/6 and Dectin-2-deficient (KO) mice.
