Mechanism of Action: Taming thee Autoimmunome Response

Te autoimmunologiczne attack in T1D is driven by autoreactive T cells that target specific proteins, or autoantigens, found on beta cells. Tolerance-inducing vaccines are designed to deliver these autoantigens in a contect that promotes regulation rather than activation. The goaal is to selectively expand regulatory T cells (Tregs) or induce anergy (non -responsiveness) in thee effectitor T cells that cause damage.
