Abstract:
:Viral infections often result in long-term immunological memory. This article reviews the phenotypic changes seen in memory T cells and suggests a re-evaluation of the current dogma that T cell memory is maintained by persistence of antigen.

杂志文章,评审abstract::Metazoan parasites typically induce a type 2 immune response, characterized by T helper 2 (Th2) cells that produce the cytokines IL-4, IL-5 and IL-13 among others. The type 2 response is host protective, reducing the number of parasites either through direct killing in the tissues, or expulsion from the intestine. Typ...
