title: [Effect of colchicine on virus-induced interferon synthesis in chick embryo cells].
abstract: Colchicine, at a concentration of 5 X 10(-4) M (0.2 microgram/ml), inhibits interferon synthesis induced by theLee strain of influenza B virus in chick embryo cells, but it does not influence the release of preformed interferon from cells. The same drug concentration does not affect the overall synthesis of cellular RNA and protein. The inhibition of interferon synthesis by colchicine is a temperature-dependent process and is not manifested at 0 degrees C. Colchicine is found to be most effective when it is introduced into the medium at early stages of infection. It is suggested that colchicine inhibits the formation of messenger RNA for interferonogenesis.
