Also consistent with ANA results, some mice that received the Hexapro SARS2-CoV spike were positive for anti-dsDNA (SLE), U1-snRNP70 kDa [associated with SLE and mixed connective tissue disease (19)], gliadin [associated with celiac disease (20)], and, to a lesser degree, tissue transglutaminase [celiac disease (21)]. Here, TGM2 is linked to mixed connective tissue disease.
