T 细胞在胸腺中发育成熟后,它们可以在血液或淋巴系统中游走或迁移到体内不同器官。接收到特定的抗原刺激后,辅助 T 细胞会产生化学物质。有些化学物质触发 B 细胞发育成浆细胞,而另一些化学物质刺激杀伤性 T 细胞靶向杀死可能被感染或癌变的细胞。调节性 T 细胞有助于控制免疫反应,防止其失控。自然杀伤 T 细胞也...

T cells in skin lesions exhibit oligoclonality that persists over time, which indicates an antigen-driven T cell activation, but the antigen(s) responsible are not known. There are known environmental factors that can elicit an immune response and cause a SSc-like disease. T cells also provide...
It is commonly believed that only T lymphocytes and B lymphocytes expressing recombination-dependent antigen-specific receptors mediate contact hypersensitivity responses to haptens. Here we found that mice devoid of T cells and B cells demonstrated subs

The last case was diagnosed as a ja:math T-cell lymphoma. Differences in morphology proliferative characteristics were recognized between B- and T-cell type lymphomas. The tumor cells in B-cell type lymphoma were characterized as follows: medium or large in size, round or polymorphic nucleus ...

Functional analysis of the role of different T-cell subsets identified the Th1 responses as proatherogenic, whereas regulatory T-cell responses exert antiatherogenic activities. The effect of Th2 and Th17 responses is still debated. Atherosclerosis is also associated with B-cell activation. Recent ...

The target cells for infection and transformation by Theileria parva were investigated. Peripheral blood mononuclear cells were reacted with monoclonal antibodies specific for bovine leukocyte differentiation antigens, sorted into subpopulations with a f
