When it comes to infecting humans and animals, bacteria need a helping hand.
Kansas State University biochemists have found the helping hand: groups of tiny protein loops on the surface of cells. These loops are similar to the fingers of a hand, and by observing seven individual loops on the ... Read More
Vincent travels to Albert Einstein College of Medicine where he speaks with Kartik, Ganjam, and Margaret about their work on Ebolavirus entry, a tumor suppressor that binds the HIV-1 integrase, and the entry of togaviruses and flaviviruses into cells.
