Identification of Differentially Expressed miRNAs in Alopecia Areata That Target Immune-Regulatory Pathways

miR-205, a tiny RNA, can stimulate hair growth by softening aging hair follicle stem cells in mice. Future tests aim to see if this can work in humans.

Balding scalps have more androgen receptors, leading to increased TGF-beta, which causes blood vessel loss and hair follicle miniaturization. Blocking androgen signaling and TGF-beta may help prevent hair loss.

Hair loss treatments like Minoxidil, finasteride, and potential mRNA therapies are discussed. There is skepticism about targeting specific genes due to the complex genetic nature of hair loss.

IGFBP‐rP1 shows potential for treating androgenic alopecia by influencing hair cycle transitions. Increasing IGF-1 levels may have similar effects to Minoxidil and 5-AR inhibitors in reducing hair loss.

Pilose antler extracts may promote hair growth in androgenetic alopecia by activating hair follicle stem cells through the AKT and Wnt pathways. However, results in mice may not directly apply to humans due to differences in genetic and biochemical conditions.

DHT may inhibit hair growth by affecting mitochondrial function, leading to hair follicle miniaturization. Treatments like minoxidil and PP405 may promote hair growth by altering metabolic pathways, potentially counteracting DHT's effects.
