Figure 3: Blue light exposure reduces IL-1β cytokine levels in the culture medium of primary microglia treated with LPS.

Figure 3

Primary microglia were exposed to blue light (450 nm) for 1 second per min at an intensity of 100 mW/cm2 and treated with either vehicle or LPS (1 μg/mL) for 6 hours. Data are graphed as means + 1 SEM of arbitrary units normalized to the LPS only condition. IL-1β levels were below the detection threshold of the assay and are designated as not detectable (N.D.). n = 3, ***P < 0.001 student’s t-test.
