Description

Egbase and a large team showed in 2026 that blocking an enzyme called NAMPT shields insulin-making beta cells from autoimmune attack. The enzyme raises levels of NAD, a core metabolic molecule, and the team suspected excess NAD fuels islet inflammation killing beta cells. They tested a blocker on mouse and human islets bathed in inflammatory signals, and a mouse diabetes model received it for 16 days.

Protection was broad: in isolated islets, the blocker preserved insulin release and prevented cell death under cytokine attack. Gene profiling showed it silenced inflammatory and cell-recruitment programs, and in diabetic mice treatment improved blood sugar control and beta-cell survival. Immune invaders inside islets thinned out, and killer T cells lost their ability to migrate into islets in dish tests. The authors float NAMPT blocking as a therapy candidate, and caution that NAD-boosting supplements deserve scrutiny in people at risk of this disease.
