An aging-related pathological process (that of mitochondrial degeneration) is present in these specific hypothalamic astrocytes. This mitochondrial degeneration can be accelerated by access to a high-fat diet, which also induces hypothalamic resistance to leptin, generalized insulin resistance, and an abnormal glucose homeostasis. An impaired astrocyte-neuron signaling, caused by this pathological mitochondrial degeneration, may underlie an abnormal hypothalamic function that leads to the development of type II diabetes. Pharmacological agents that protect astrocytes from mitochondrial degeneration may have a place in the treatment of type II diabetes.
