The gut-thyroid axis describes the bidirectional communication between the gut microbiome and the thyroid gland. The thyroid regulates metabolism, energy homeostasis, and immune function -- and the microbiome influences thyroid physiology at every level: mineral absorpt…
Molecular mimicry occurs when microbial antigens share structural similarity with host proteins, triggering cross-reactive immune responses that attack host tissue. It is a primary mechanism linking infections and dysbiosis to autoimmune disease — the immune system corr…
Autoimmune thyroid diseases (AITDs) -- hashimotos thyroiditis and graves disease -- are the most common organ-specific autoimmune conditions, affecting 5-10% of the global population. The thyroid gland sits at a remarkable intersection of metal biology and immune regula…
Vitamin B12 (cobalamin) is an essential cobalt-containing cofactor required for homocysteine metabolism, methylation reactions, and neurological function. Its core corrin ring chelates a cobalt ion, placing B12 at the intersection of metallomics and microbial ecology. C…
Vitamin D (calciferol; active form: calcitriol/1,25(OH)₂D₃) is a secosteroid hormone with profound immunomodulatory effects. The vitamin D receptor (VDR) is expressed on virtually all immune cells, and vitamin D deficiency is epidemiologically linked to autoimmune disea…
