alopecia areata immune-related biomarkers T cell subtypes CXCL9 CXCL10 MIR155HG TSPOAP1-AS1 CCL13 IL21R chemokines

The study analyzed immune-related biomarkers in alopecia areata (AA) by examining expression data from 60 individuals with AA and 36 controls, identifying 1,708 IncRNAs and 17,326 mRNAs, with 427 differentially expressed regions. It highlighted the autoimmune nature of AA, noting significant differences in T cell subtypes and identifying CXCL9 and CXCL10 as key prognostic factors with high diagnostic potential (AUC values of 0.87 and 0.836). The research also pointed to other biomarkers like IncRNAs MIR155HG and TSPOAP1-AS1, and genes CCL13 and IL21R, suggesting their roles in AA progression. These findings underscore the importance of T cell subsets and specific chemokines in AA, proposing potential targets for new therapies and emphasizing the need for further validation in larger cohorts.

community DHEA, the culprit behind DUPA ? Read this!

in Research/Science 19 upvotes 2 years ago

High DHEA levels may contribute to hair loss by increasing DHT in hair follicles, potentially explaining why finasteride is ineffective for some. Treatments like high-dose dutasteride and RU58841 are suggested, but the underlying cause, such as adrenal issues, should be investigated.
