Abstract

Photoaging is a consequence of chronic exposure to ultraviolet (UV) radiation and results in skin damage. In this study, whether tyndallizate of the probiotic bacterium Lactobacillus acidophilus IDCC 3302 (ACT 3302) can protect against UVB‑induced photodamage to the skin was investigated. For this, HaCaT keratinocytes were used as a model for skin photoaging. HaCaT cells were treated with ACT 3302 prior to UVB exposure and skin hydration factors and matrix metalloproteinase (MMP)‑1, MMP‑2, and MMP‑9 levels in the culture supernatant were evaluated by ELISA. The protective effects of ACT 3302 against UVB‑induced oxidative stress in HaCaT cells was also assessed by measuring superoxide dismutase and catalase activity and detecting the expression of pro‑inflammatory cytokine‑encoding genes and mitogen‑activated protein kinase (MAPK) signaling components by reverse transcription‑quantitative polymerase chain reaction and western blotting, respectively. UVB exposure increased MMP expression and MAPK activation; these changes were attenuated by pretreatment with ACT 3302. Treatment with ACT 3302 prior to UVB exposure also attenuated inflammation. These results demonstrate that tyndallized ACT 3302 can mitigate photodamage to the skin induced by UVB radiation through the suppression of MMPs and could therefore be used clinically to prevent wrinkle formation.
