Conditioned media from blue light-emitting diode–exposed fibroblasts have an anti-inflammatory effect in vitro

Blue light irradiation exerts anti-viral and anti-inflammatory properties against herpes simplex virus type 1 infection

“…Its combination with near-infrared light has been shown to be more effective for wound repair by stimulating proliferation and collagen synthesis in fibroblasts [ 25 ]. Recently, we published experimental data using a phototherapeutic approach with blue light without photosensitizers in various cancer cells both in vitro and in vivo [ [26] , [27] , [28] , [29] , [30] , [31] ]. Especially, low-level BL exerted anti-proliferative, anti-inflammatory, and anti-metastatic effects, whereas high-level BL induced the apoptosis of cancer cells depending on the number of irradiating photons.…”
