|+||[[Virus]] coded [[cell]] surface antigens that appear soon after the [[infection]] of a cell by virus, but before virus replication has begun. |
|+||See: early [[gene]]. Any substance (as a toxin or [[enzyme]]) that stimulates the production of [[antibodies]].Antigens are considered to be foreign agents within an [[organism]], and therefore must be removed so that the body can continue with its normal cellular processes without hindrance. These antigens produce an [[immune response]] by the organism in response to their presence. |
