2022年4月10日 · Thymus-derived lymphocytes or T cells are cells of the immune system that are an essential part of the adaptive immune system. These are blood cells (leukocytes) that act by attacking invading pathogens and host cells based on the type of T cell activated.
T淋巴细胞 - 百度百科
T淋巴细胞（T lymphocyte）简称T细胞，是由来源于骨髓的淋巴干细胞，在胸腺中分化、发育成熟后，通过淋巴和血液循环而分布到全身的免疫器官和组织中发挥免疫功能 [1]。 多能干细胞 转变为淋巴样前体细胞（Lymphoid precursor）迁移至胸腺，在胸腺素的诱导下，经历一系列有序的分化过程，逐渐在胸腺发育成熟为识别各种抗原的T细胞库。
T cell - Wikipedia
T cells are one of the important types of white blood cells of the immune system and play a central role in the adaptive immune response. T cells can be distinguished from other lymphocytes by the presence of a T-cell receptor (TCR) on their cell surface. T cells are born from hematopoietic stem cells, [1] found in the bone marrow.

What are T cells (T lymphocytes)? T cells are a type of white blood cell called lymphocytes. They’re also called T lymphocytes. Lymphocytes play an essential role in your immune system. Your immune system fights infection-causing pathogens (viruses, bacteria, fungi and parasites) and harmful cells, like cancer cells.

2024年10月15日 · T Cell Production and Maturation. T cells, like all other white blood cells involved in innate and adaptive immunity, are formed from multipotent hematopoietic stem cells (HSCs) in the bone marrow (see Figure 17.3.1).However, unlike the white blood cells of innate immunity, eventual T cells differentiate first into lymphoid stem cells that then become small, immature lymphocytes, sometimes ...
