Acne is a chronic inflammatory skin disorder that often involves the formation of C. acnes biofilms. Several microRNAs (miRNAs) are known to be involved in inflammatory responses. However, it is unknown whether miRNAs play a role in the inflammatory reaction triggered by C. acnes biofilm. Here we investigated the role of miR-146a in biofilm-derived C. acnes induced inflammatory responses. Increased expressions of miR-146a and toll-like receptor (TLR) 2 were detected in acne lesions. In presence of biofilm-derived C.
