      research Genome-Wide Association Study in Alopecia Areata Implicates Both Innate and Adaptive Immunity

      717 citations, June 2010 in “Nature”
      A genome-wide association study conducted on 1,054 cases and 3,278 controls identified several susceptibility loci for alopecia areata, suggesting the involvement of both innate and adaptive immunity in the disease. The study highlighted significant associations with genes related to regulatory T cells, CTLA4, IL-2/IL-21, IL-2RA, and the HLA region, as well as genes expressed in the hair follicle like PRDX5 and STX17. Notably, the ULBP gene cluster on chromosome 6q25.1, encoding ligands for the natural killer cell receptor NKG2D, was implicated for the first time in autoimmune disease, with ULBP3 expression upregulated in the hair follicle during active disease. This research provided insights into the genetic basis of alopecia areata and suggested a novel mechanism involving ULBP ligand upregulation in autoimmunity.

      community Hair loss and ethnicity - Caucasian men the most likely to experience hair loss

      in Chat  17 upvotes 1 year ago
      The conversation discusses how Caucasian men are more likely to experience hair loss due to genetic predisposition, with factors like the androgen receptor on the X chromosome playing a significant role. The user also expresses confusion about the evolutionary reasons for hair loss, especially in colder climates where it would seem beneficial to retain hair for warmth.

      community Female, 30, PCOS diagnosis, MPB Norwood 2. Endo refuses to give anything other than Spironolactone. Feel like I’m at my wit’s end here.

      in Female  57 upvotes 10 months ago
      A 30-year-old female with PCOS and male pattern baldness is frustrated with her endocrinologist's recommendation of only Spironolactone and minoxidil, feeling that dutasteride, finasteride, and progesterone would be more effective. Other users suggest various online sources for treatments, warn against self-medicating due to potential risks, and recommend seeking a specialized endocrinologist or considering additional treatments like Inositol, Berberine, and dermaneedling.
