2. Any of a group of synthetic glycoproteins that are structurally similar to these compounds and are used therapeutically, especially as antivirals.
(Biochemistry) biochem any of a family of proteins made by cells in response to virus infection that prevent the growth of the virus. Some interferons can prevent cell growth and have been tested for use in cancer therapy
