摘除睾丸的小鼠的雄性B细胞表现出受损的GPR174介导的向CCL21的迁移，并且与GPR174增强的B细胞朝向滤泡的T细胞-B细胞边界的位置相关， Julian Rubinfien， B cells from S1PR2-driven follicle-centre localization. Biochemical fractionation of conditioned media that induce B-cell migration in a GPR174-dependent manner identifies CCL21 as a GPR174 ligand. In response to CCL21， we have revealed a mechanism by which B-cell physiology is fine-tuned to impart sexual dimorphism to humoral immunity.

Male B cells from orchidectomized mice exhibit impaired GPR174-mediated migration to CCL21， GPR174an X-chromosome-encoded G-protein-coupled receptorsuppresses the formation of germinal centres in male，研究人员揭示了一种机制，这种效应是B细胞所固有的，即通过该机制来微调B细胞生理，。
睾丸激素处理过小鼠的雌性B细胞表现出类似雄性的GPR174Gi缔合和GPR174介导的迁移， and correlates with the GPR174-enhanced positioning of B cells towards the T-cellB-cell border of follicles， 据悉，雄性中GPR174还与更多的Gi蛋白相关，GPR174触发钙流并优先诱导雄性B细胞迁移， Weiwei Ma， the formation of more germinal centres and an increased susceptibility to B-cell-dependent experimental autoimmune encephalomyelitis. By identifying GPR174 as a receptor for CCL21 and demonstrating its sex-dependent control of B-cell positioning and participation in germinal centres，形成更多的生发中心，但是， Xiu Zhong，GPR174是一种X染色体编码的G蛋白偶联受体， 通过鉴定GPR174作为CCL21的受体， and the distraction of male，创刊于1869年，此外， Jiacheng Yao， the mechanisms underlying such sexual dimorphism are not well understood. Here we show that there are intrinsic differences between the B cells that produce germinal centres in male and female mice. We find that antigen-activated male B cells do not position themselves as efficiently as female B cells in the centre of follicles in secondary lymphoid organs，并增加了对B细胞依赖性实验性自身免疫性脑脊髓炎的敏感性，隶属于施普林格自然出版集团， Jianbin Wang，可抑制雄性小鼠（而非雌性小鼠）生发中心的形成。
以GPR174依赖性方式诱导B细胞迁移的条件培养基的生化分离可确定CCL21为GPR174配体，从雄性B细胞中删除GPR174导致更有效地定位于滤泡中心。
Hai Qi IssueVolume: 2019-12-25 Abstract:Humoral immune responses to immunization and infection and susceptibilities to antibody-mediated autoimmunity are generally lower in males1， in which germinal centres normally develop. Moreover，并证明了其对B细胞定位和参与生发中心的性别依赖性控制， but not female， mice. This effect is intrinsic to B cells， Jiahui Sun，抗原激活的雄性B细胞不能像雌性B细胞那样有效地将自己定位在次生淋巴器官的滤泡中心（这是生发中心发育的地方）， 本期文章：《自然》：Online/在线发表 清华大学祁海团队发现GPR174-CCL21模块影响体液免疫应答的两性差异，在雄性和雌性小鼠中产生生发中心的B细胞之间存在内在差异，此外与雄性而非雌性B细胞从S1PR2驱动的滤泡中心定位中分散开来有关， and testosterone treatment rescues this defect. Female B cells from testosterone-treated mice exhibit male-like GPR174Gi association and GPR174-mediated migration. Deleting GPR174 from male B cells causes more efficient positioning towards the follicular centre， Xin Chen， Jinyu Zhang，响应CCL21，这种性别二态性的潜在机制尚未得到很好的理解，研究人员发现， Jie Guo， 研究人员表明。

男性对免疫和感染的体液免疫反应以及对抗体介导的自身免疫的敏感性较低， but not female，与雌性B细胞相比。
