Studies on lmmunoregulation of Cytokine of Chickens after Inoculation with Marek‘s Disease Vaccines

摘要

The spleenic and thymus T lymphocyte proliferaitive reactions(TLPR) were enhanced,the interleukin 2(IL-2)inductive activity was raised,and the IL-2 receptor (IL-2R)iductive expression was increased significantly in chickens after inoculation with trivalent Marek's discase vaccine in comparison with control chickens and those after vaccination with herpesvirus of turkey (HVT) vaccine.In chickens after inoculation with HVT vaccine,in contrast with control chickens,the spleenic TLPR was strengthened and IL-2R inductive expression was hoisted significantly,the thymus TLPR,spleeinc and thymus T lymphocyte IL-2 inductive activity,the thymus T lymphocyte IL-2R inductive expression were not significantly increased.
