Specialized white blood cells called T cells and B cells are critical for immunity - helping the body to identify and eliminate "non-self" substances such as viruses and bacteria. The activation of T cells and B cells occurs when immunoreceptors on the cell surface bind to specific regions ...

近日,来自斯隆-凯特林癌症研究所的Jayanta Chaudhuri带领团队在Nature Immunology杂志上发表了文章“Distinct metabolic requirements regulate B cell activation and germinal center responses”。他们发现,在未成熟的B细胞中敲除LDHA会严重影响B细胞后续的成熟以及生发中...
对于某些免疫原,疫苗接种后稳定的抗体滴度已经观察了 20 年或更长时间。 参考: edia.org.za/immunology/basics/6-b-cell-activation-and-plasma-cell-differentiation/ 感谢点赞,及转发分享的朋友。 公众号开放转载,同样欢迎大家提出需求、留言与探讨。
The T cells provide the signals that the B cells need to proliferate and differentiate into clones of antibody-secreting plasma cells, and memory B cells. During birth in the bone marrow, each B cell assembles a gene encoding a unique antibody molecule, which it puts on the cell surface ...
