Connection between Covid-19 and Celiac Disease?

 I was talking with one of my professors this morning and she mentioned how her husband developed Celiac Disease after contracting Covid-19. I decided to do more research on it because it seemed so interesting and weird how these two different conditions coincide with each other. Recent research suggests COVID-19 may help trigger celiac disease in genetically susceptible people, because apparently SARS-CoV-2 couldn’t resist adding “autoimmunity starter kit” to its résumé. The virus can bind to ACE2 receptors in the small intestine, disrupt tight junction proteins, scramble the gut microbiome, and crank up cytokines like IL-6 and IFN-Y, creating the physiological equivalent of a messy group project where no one communicates. In individuals with HLA-DQ2 or HLA-DQ8 genes, this inflammatory chaos may accidentally target tissue transglutaminase, the enzyme that becomes the main character in celiac disease, leading the immune system to declare gluten as Public Enemy #1. To be clear, COVID doesn’t just hand out celiac disease like party favors, but if you already had the genetic setup, the viral gut drama might be the final nudge your immune system needed to overreact in spectacular fashion. I truly feel bad for anyone with celiac disease because I love bread and anything with gluten and I would be DEVASTATED if I couldn't have bread anymore in my life.
