在从鲨鱼到哺乳动物的有颚脊椎动物中,胸腺是T细胞发育和成熟的主要(或中央)淋巴组织。胸腺中特定的基质细胞类型、细胞因子环境和组织结构对于V(D)J重组、主要组织相容性复合物识别的阳性选择和针对大多数αβ T细胞的自身肽识别的阴性选择至关重要。这里描述的爪蟾蝌蚪幼虫的胸腺切除术创造了一个适合许多免疫学研究的T细胞缺陷模型。
In jawed vertebrates from sharks to mammals, the thymus is the primary (or central) lymphoid tissue where T cells develop and mature. The particular stromal cell types, cytokine environment, and tissue organization in the thymus are essential for V (D) J recombination, positive selection for major histocompatibility complex recognition, and negative selection against self-peptide recognition of most αβ T cells. The thymectomy operation on Xenopus tadpole larva described here creates a T-cell–deficient model suitable for many immunology studies.
