My study is focusing on the formation and plasticity of dendritic spines. Dendritic spines are tiny actin-enriched protrusions emanating from dendritic shafts that constitute the major compartments of excitatory post-synapses. Activity-dependent spine enlargement underlying the process of learning and memory in the brain. Elucidating the molecular mechanism of spine enlargement can provide new targets for therapeutics of several mental disorders or neurodegenerative diseases.
