UVB-Induced Secretion of IL-1β Promotes Melanogenesis by Upregulating TYR/TRP-1 Expression In Vitro

Figure 1

mRNA levels of inflammatory cytokines in C57BL/6 mouse skin at different time points after UVB irradiation at a dose of 120 mJ/cm². The RT-qPCR method was used to detect the mRNA expression of IL-1α, IL-1β, IL-6, IL-10, IL-17, and TNF-α level (a–f). for all groups. and .
