Endothelial cells are highly heterogeneous at the level of cytokine-induced insulin resistance.

The endothelial wall plays a crucial role in various diseases as it serves as the barrier between circulatory system and organ tissue. Inflammation-driven insulin resistance and subsequent endothelial dysfunction represent a pathomechanism in cardiovascular diseases such as atherosclerosis and myocardial infarction. It was recently suggested that insulin resistance also contributes to the pathogenesis of psoriasis, a chronic inflammatory disease of the skin.

Interleukin-1β interferes with epidermal homeostasis through induction of insulin resistance: implications for psoriasis pathogenesis.

Response pathways of the metabolic and the immune system have been evolutionary conserved, resulting in a high degree of integrated regulation. Insulin is a central player in the metabolic system and potentially also in the homeostasis of the skin. Psoriasis is a frequent and often severe autoimmune skin disease, clinically characterized by altered epidermal homeostasis, of which the molecular pathomechanisms are only little understood.
