MCB 9509105 Catherine Walsh This proposal is designed to provide valuable preliminary data contributing to the long-term goal of characterizing thymic function in cartilaginous fish, the most primitive groups of jawed vertebrates to possess a distinct thymus. The work focuses on the preliminary characterization of possible phylogenetic equivalents of specialized cells identified in mammalian thymi as thymic nurse cells. The thymic nurse cells are suspected to have roles in interthymic T-cell maturation and/or removal of nonfunctional or self reactive thymocytes. The research planning grant will be used to develop a full research proposal to characterize the functional role and evolutionary significance of elasmobranch thymic cells. %%% This project will investigate the evolution of the thymus and the interrelation of cells in the thymus. It will provide evidence to explain how cells acquire different functions in the body of an organism. ***

MCB 9509105凯瑟琳·沃尔什（Catherine Walsh）该提案旨在提供有价值的初步数据，这有助于表征软骨鱼中胸腺功能的长期目标，这是最原始的颌脊椎动物群体具有独特的胸腺。 这项工作的重点是在哺乳动物胸腺中鉴定为胸腺护士细胞的特殊细胞的系统发育等效物的初步表征。 怀疑胸腺护士细胞在心理学T细胞成熟和/或去除非功能或自反应性胸腺细胞中具有作用。 研究计划赠款将用于制定一项完整的研究建议，以表征弹性细胞的功能作用和进化意义。 %% %%该项目将研究胸腺中胸腺的演变和胸腺中细胞的相互关系。 它将提供证据来解释细胞如何在生物体体内获得不同的功能。 ***
