TLDR VEGF and its receptor might cause hair loss.
This article suggests that vascular endothelial growth factor (VEGF) and its receptor may be a molecular mechanism for androgenetic alopecia (AGA). Dihydrotestosterone (DHT) binds to androgen receptors in hair follicles, down-regulating the expression of VEGF in dermal papilla cells (DPC), which leads to hair loss. The document also briefly mentions the role of serotonin in viral hepatitis and proposes a modification to the rapid tryptophan depletion (RTD) procedure to potentially reduce virus persistence and immunopathology.
