LLLT reduced IL-12 secretion from DC stimulated by either LPS or CpG. (TLR)-9/nuclear element kappa B (NF-B) activation, were performed. LLLT changed the morphology of LPS-stimulated DC, improved their viability, and modified the balance of DC activation markers (major histocompatibility complex [MHC] class 2 up and CD86 down). LLLT reduced IL-12 secretion from DC stimulated […]
