How exactly do enteroviruses trigger ors compaster Type 1 Diabetes? The answer likely contingvess mulple, interconnected mechanisms that vary deposing on viral strain, host genetics, and timing of exposure.

Molecular Mimicry

A more specific mechanism involves cross-reaktivity beta-cel autoantigen.
