When skin cells are exposed to UVB light, certain inflammation-related genes turn on — but this doesn't happen as much when a specific protein called ZAK is removed.

The ribotoxic stress response drives acute inflammation, cell death, and epidermal thickening in UV-irradiated skin in vivo

Randomized Controlled Trial

The study shows that turning off a protein called ZAKα reduces skin cell inflammation after UVB light, which supports the idea that this protein helps control the body’s early sunburn response.

Similar Assertions

When skin cells are hit by UVB light, they can die and send out inflammation signals — but this happens even if their DNA damage repair system is broken, so that system isn't needed for this response.
