Human leukocyte antigen (HLA) genes are associated with more diseases than any other region of the genome. Highly polymorphic HLA produce variable haplotypes that specifically correlated pathogenically different autoimmunities. Despite differing etiologies, however, many autoimmune disorders share same risk-associated often resulting in comorbidity. This shared risk remains an unanswered question field. Yet, several groups have revealed links between gut microbial community composition and diseases. Autoimmunity is frequently dysbiosis, loss barrier function permeability tight junctions, which increases class II expression levels thus further influences microbiome. However, autoimmune-risk-associated connected to dysbiosis long before autoimmunity even begins. review evaluates current research on HLA-microbiome-autoimmunity triplex proposes pre-autoimmune bacterial important determinant comorbidities systemic inflammation as a common denominator.

Background: Thyroid-associated ophthalmopathy (TAO, aka thyroid eye disease [TED], Graves' orbitopathy) remains poorly understood and inadequately treated since its initial description. It is disfiguring, can threaten vision, represents an autoimmune process closely associated with disease. Unambiguous connections linking TAO to the glandular maladies of (GD) remain incompletely clarified. Detecting thyrotropin receptor (TSHR) in periocular tissues suggests that this cell-surface protein a shared autoantigen gland, but we now know expression ubiquitous. Most patients have relatively high circulating levels activating anti-TSHR autoantibodies. Emerging more recently importance insulin-like growth factor I (IGF-IR) pathogenesis TAO. The TSHR/IGF-IR signaling complex apparently drives fibrocytes unique phenotypes fibroblasts inhabiting orbit (GD-OF).
