In 2 papers, researchers describe potential new neurodegenerative disease treatment approach

William McEwan, Ph.D., spent years unraveling how an antiviral protein, tripartite motif-containing 21 (TRIM21), protects our cells from infection. Working in the lab of Leo James, Ph.D., McEwan and collaborators realized that TRIM21 marks viruses to be destroyed by the cell’s waste disposal system—but only activates when enough of the proteins cluster together.
