Skin macrophage
WebbThese form macrophages. The skin cells communicate by releasing large numbers of biologically active cytokines and chemotactic factors that regulate their function and movement. These are too small to see on light microscopy. C. Subcutis. The subcutis is the fat layer immediately below the dermis and epidermis. WebbThe causes of immune dysregulation in atopic dermatitis (AD) remain poorly understood. Distinct clinical endotypes of AD are known, but an in vivo model of the Th2-dominant AD endotype is not well established. Macrophages have long been described in AD skin, and CCL18, a highly induced biomarker that correlates with disease activity, is derived from …
