这一研究成果于2024年1月15日在线发表在的国际学术期刊《免疫》上, 附:英文原文 Title: Lack of affinity signature for germinal center cells that have initiated plasma cell differentiation Author: Henry J. Sutton,这些细胞对恶性疟原虫环孢子虫蛋白(PfCSP)具有特异性, 研究人员表示,提供持续的抗感染免疫力, we identified 3 populations of cells in the GC light zone (LZ). OneLZ population expressed a gene signature associated with the initiation of PC differentiationand readily formed PCs in vitro. The estimated affinity of these pre-PC B cells was indistinguishable from that ofLZ cells that remained in the GC. This remained true when high- or low-avidity recombinantPfCSP proteins were used as immunogens. These findings suggest that the initiation ofPC development occurs via an affinity-independent process.
