Abstract
Caspase-8 downregulation is observed in the epidermis of wounded skin, whereas permanent epidermal caspase-8 deletion causes chronic skin inflammation, suggesting that caspase-8 is a critical regulator of skin homeostasis and, possibly, the wound response. In this issue, Lee et al. document how epidermal caspase-8 deletion, or cutaneous wounding, results in increased NF-kappaB activation to drive keratinocyte caspase-1 expression and subsequent secretion of the pro-inflammatory cytokines, IL-1beta and IL-1alpha. Consequently, loss of NF-kappaB activity, caspase-1, or the IL-1 receptor delays wound healing. Previous studies have documented how chronic skin inflammation in caspase-8-deficient mice is rescued by RIPK3 co-deletion. Therefore, targeting caspase-1, IL-1, or RIPK3 itself may benefit treatment of chronic inflammatory skin diseases, or where an inappropriate inflammatory response proves detrimental to wound healing, such as in type 2 diabetes.
