Molecular mimicry is a possible cause of some forms of autoimmunity due to bacterial infection..Do fungal/viral infections ever cause autoimmunity?
Molecular mimicry: Why yes viral infections certainly do display molecular mimicry. Most commonly are the herpesvirus family (herpes simplex, varicella, cmv, ebv...16 in all). That is why these viruses remain latent within us and if the immune system is disrupted by acquired immunodeficiencies (age, chemotherapy, HIV or other viral infections) these viruses then reactivate. ...Read more

I suffer from granuloma annulare, erythema annulare centrifugum, erythema nodosum, and low IgM. Are these related or might they have a common cause?
Unlikely: These 3 conditions have 3 different auto-sensitivity targets, in the skin. Biopsy appearance is different under the microscope, and treatments are different. The first 2 conditions usually respond poorly to any cream, but are not serious. E. Nodosum can be a sign of a more serious underlying disease, and stronger meds are needed. Please see a Dermatologist for treatment. ...Read more

Drugs and toxins can also directly cause atn. ...Read more
