M1 J774 macrophages were irradiated with two different sets of laser parameters.
IL-6, TNF-α, iNOS and COX-2 expression were analyzed by RT-qPCR and ELISA.
660 nm laser reduced the expression of TNF-α, iNOS and COX-2 in M1 J774 macrophages.
660 nm laser increased the expression of IL-6 in M1 J774 macrophages.
780 nm laser reduced IL-6, TNF-α, iNOS and COX-2 expression in J774 macrophages.
