Targeting Phosphodiesterase 8A (PDE8A) to Boost Adipogenesis and Hair Regeneration

Adipose-derived stem cells with ATP improved hair regrowth in male and female mice with androgenetic alopecia. The most effective treatments were low dose stem cells with ATP for males and medium dose stem cells with non-liposomal ATP for females.

GT20029 is a new hair loss treatment in Phase 3 trials in China, using PROTAC technology to target androgen receptors, potentially with fewer side effects than finasteride and minoxidil. VDPHL01, a second-generation minoxidil, is also mentioned as potentially more effective.

Androgenic alopecia (AGA) might have evolved to reduce prostate cancer risk by increasing UV exposure to the scalp, but this theory is debated. Treatments like minoxidil and finasteride are used for AGA, though the exact causes and evolutionary reasons for hair loss are unclear.

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.

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.

Hair loss may be linked to the TRPS1 gene and protein, not just DHT. Amplifica's AMP-303 targets mesenchymal stem cells and shows promise in treating hair loss, unlike Pelage's PP405.
