Studies have demonstrated that neuronal senescence is a prevalent pathological characteristic of various neurodegenerative diseases, with ferroptosis playing a significant role. This study aims to investigate the role of ErbB4 receptor activation in preventing D-Galactose (D-gal)-induced neuronal senescence. Utilizing a small molecule ErbB4 receptor agonist (E4A) identified through virtual screening, it was observed that activation of the ErbB4 receptor significantly ameliorated the behavioral deficits induced by D-gal in mice. This effect is comparable to that of melatonin, a natural inhibitor of in vivo senescence and ferroptosis. Subsequent research demonstrated that both the ErbB4 receptor agonist and melatonin (MLT) ameliorate Dgal-induced aging in hippocampal neurons of mice. This is evidenced by the upregulation of Lamin B1 and the downregulation of P53, P21, P16, GFAP, and Iba-1 expression levels. Moreover, D-gal treatment markedly decreased the protein expression of the ferroptosis inhibitor Nrf2 while augmenting the expression of the ferroptosis promoter TFRC. These alterations were partially reversed by the individual administration of the E4A and MLT. In vitro studies further corroborated that D-gal treatment significantly and concurrently induced the expression of senescence markers and ferroptosis promoters. However, both E4A and MLT were able to significantly reverse these changes. Additionally, E4A markedly ameliorated Erastin-induced ferroptosis in mouse hippocampal neuronal cells. Collectively, our data suggest that targeted activation of the ErbB4 receptor may be a viable strategy for treating neuronal senescence by inhibiting ferroptosis, thereby offering a potential therapeutic avenue for senescence-associated neurodegenerative diseases.
