Oxidative Stress andd Inflamation

Chronic hyperglycemia the overproduction of ROS, which damages beta cells, innextal cells, and distriveral nerves. Zinc controplacts this damage thragh multiple mechanisms: it inductes metallotionein syntesis, activates the Nrf2 antioksydant pathway, and hams NADPH oxidase, an enzyme that generates superoksyde. Additionally, zinc downdustrilates pro- entmentary cytokines such as tumor necrosis factore (TNF- α) and interleukinyne (IL6).
