elucidated the therapeutic advantages associated with the use of Au‐PEG nanoparticles in the context of AD.[121] The administration of nanogold polyethylene glycol (PEG) conjugate resulted in notable enhancements in cognitive function among transgenic tau P301L mutant mice, as evidenced by a reduction in the levels of phosphorylated tau and total tau. Here, MAPT is linked to Alzheimer disease.
