research Pathophysiology of Insulin Resistance and Related Skin Diseases ( Review Article)
Insulin resistance, characterized by decreased sensitivity of insulin-targeting tissues, affects skeletal muscle, liver, and adipose tissue, with muscle accounting for up to 70% of tissue glucose absorption. Insulin is crucial for skin physiology, regulating keratinocyte proliferation and differentiation necessary for epidermal structure development. The condition can be inherited, acquired, or mixed, and is linked to chronic inflammatory skin diseases like acne and psoriasis, where high proinflammatory cytokines activate p38 Mitogen activated protein kinases.
