Retinoic acid, a metabolite of vitamin A, plays a critical role in neural development and differentiation. It regulates gene expression by activating nuclear retinoic acid receptors (RARs), which influence neuronal patterning, synaptic plasticity, and neurogenesis. In neurodegenerative disease research, retinoic acid has been studied for its ability to promote neuronal survival and regeneration. It is also involved in modulating inflammatory responses and oxidative stress, making it a candidate for therapeutic intervention in conditions such as Alzheimer's and Parkinson's disease.
