Epithelial cells lining our airways are chiefly seen arsenic a structural barrier, but compartment biologist Jody Rosenblatt, who runs a laboratory astatine the Crick and King's College London, believes their evolutionary past suggests they play a overmuch much progressive relation successful infections.
