Beyond cancer and vaccines, Langer’s lipid nanoparticles conquer new tissues. In a co-led study led with Li-Huei Tsai, a faculty member in the Department of Brain and Cognitive Sciences, researchers tested Langer's lipid nanoparticles in multiple mouse models and cultured human cells for their ability to deliver mRNA to the brain’s microglia immune cells and suppress expression of a protein linked to excessive inflammation in Alzheimer’s disease.
