Amphibians are undergoing a world-wide decline; certain species are becoming extinct. It is known that die-offs of some species are associated with certain viral pathogens, but it is not known why their immune systems are not protecting them. If amphibian die-offs partially reflect natural or man-made environmental changes that are immunosuppressive, awareness of these environmental factors are necessary to re-establish ecological balance for the health of man and frogs, alike. This project, uses the frog Xenopus as a laboratory model to investigate the mechanisms of viral immunity and how these organisms mount up their defenses. There are two aims: the first is to define the cellular components of viral immunity in adult frogs; and the second is to determine if the tadpoles are more susceptible due to a generalized immaturity of their immune system. This project will contribute to a better understanding of the causes of amphibian decline, which is of public interest. In addition, it will provide opportunity for minority graduate and undergraduate students to study fundamental immunology in the context of viral diseases, particularly in amphibians.

两栖动物正在经历世界范围内的下降;某些物种正在灭绝。 众所周知，某些物种的死亡与某些病毒病原体有关，但不知道为什么它们的免疫系统没有保护它们。 如果两栖动物的死亡部分反映了自然或人为的免疫抑制环境变化，那么对这些环境因素的认识对于重建人类和青蛙健康的生态平衡是必要的。这个项目，使用蛙爪蟾作为实验室模型来研究病毒免疫的机制以及这些生物体如何建立它们的防御。有两个目标：第一个是确定成年青蛙中病毒免疫的细胞成分;第二个是确定蝌蚪是否由于其免疫系统的普遍不成熟而更容易受到感染。这个项目将有助于更好地了解两栖动物减少的原因，这是公众利益。此外，它将为少数民族研究生和本科生提供机会，在病毒性疾病，特别是两栖动物的背景下学习基础免疫学。
