August 2017 in “Seoul National University Open Repository (Seoul National University)” The study investigated the role of Aminoacyl-tRNA synthetase interacting multifunctional protein 1 (AIMP1) in hair follicle stem cell proliferation and its potential as a treatment for alopecia. AIMP1, when dissociated from the multi-tRNA synthetase complex, was found to be secreted by dermal papilla cells in a sonic hedgehog (Shh) signal-dependent manner. This secretion increased the proliferation of CD34+ hair follicle stem cells by promoting the wnt signaling pathway through inhibition of sFRP1, a known wnt antagonist. The research demonstrated that the N-terminal fragment of AIMP1 could be developed into a therapeutic peptide for hair loss. When applied topically to depilated mice, this peptide significantly accelerated hair growth, especially when formulated with carbomer. The findings highlighted a novel mechanism of AIMP1 action and its potential application in alopecia treatment.
