Peripheral Insulin Sensitivity Pathway

The peripheral insulin sensitivity pathway refers to the molecular and cellular mechanisms by which insulin regulates glucose uptake and metabolism in peripheral tissues, primarily skeletal muscle, adipose tissue, and liver. This pathway involves a cascade of events starting with insulin binding to its receptor, leading to downstream signaling through IRS proteins, PI3K, Akt, and ultimately, GLUT4 translocation to the cell membrane for glucose uptake. Impairment of this pathway contributes to peripheral insulin resistance, a hallmark of metabolic disorders like type 2 diabetes and obesity.

Various, depending on the specific target within the pathway. Examples: Metformin enhances insulin sensitivity; Thiazolidinediones activate PPARγ, improving insulin sensitivity.
