Section 2.1 demonstrated that pathogenic Clostridia species mimic INS, PTPN(IA2), and GAD65 better than any other human pathogen or commensal microbe, while COX was the most likely T1DM-associated mimic of INSR, a result consistent with a previous similarity study that found very significant similarities between INS and PTPN(IA-2) [74]. Here, INSR is linked to type 1 diabetes mellitus.
