In a groundbreaking achievement, researchers have successfully combined genetics and chemistry to create a “chemogenetic” approach for enhancing memory functions. By genetically modifying the LIMK1 protein, which plays a crucial role in memory formation, to be activated by the drug rapamycin, scientists have demonstrated significant memory improvement in animal models with age-related cognitive decline. This innovative technique opens new avenues for treating memory-related neurodegenerative diseases like dementia.
Scientists at the University of Colorado Anschutz Medical Campus found that learning and memory require structural functions of CaMKII rather than enzymatic actions, opening the door to therapeutic use of inhibitors targeting only the enzymatic activity of CaMKII.
