Studysummary In this study, IL-6 expression in transgenic mice thickened the stratum corneum without causing increased epidermal proliferation or inflammation, suggesting it may enhance skin protection rather than directly induce inflammation.

The study investigated the role of Interleukin 6 (IL-6) in skin by overexpressing it in transgenic mice using a human keratin 14 promoter. The mice with the K14-IL-6 transgene were smaller and had delayed hair growth. IL-6 expression did not increase epidermal proliferation but resulted in a thicker stratum corneum, suggesting a potential role in enhancing skin protection against injury or infection. The absence of leukocytic infiltration indicated that IL-6 did not have direct proinflammatory effects in the skin. The study suggested that IL-6 might work synergistically with other factors to perform additional roles in the skin.
