两者也确实有关联:当T细胞受体(TCR)识别抗原呈递细胞(APC)上的肽/ MHC复合物,CD80 / CD86被上调并且新诱导表达CD70,这些配体分别触发CD4+和CD8+T细胞上的CD28和CD27,从而引起细胞毒性T淋巴细胞(CTL)反应,从而消除所有肿瘤细胞。 (数据来源van de Ven K, et al. Immunotherapy. 2015)CD27的激动性刺激是免疫...
CD27共刺激改善了仅通过aCD3激活的Tn细胞的增殖,但剂量过高也会对抗CD28信号传导。内化的CD27招募了信号适配器TRAF2和磷酸酶SHP-1,从而调节了TCR和CD28信号。也就是说,这是通过共招募TRAF2和SHP-1,并去磷酸化酪氨酸激酶Lck来介导的效应。与通过C...

However, the roles of CD27 and CD28 on gamma delta T-cells in allergic rhinitis (AR) have remained elusive. The aim of the present study was to investigate the expression of CD27 and CD28 on gamma delta T cells in patients with AR. Peripheral blood mononuclear cells from 14 patients ...
We employed a 8-colour flow cytometric protocol to analyse circulating T cells in 597 octogenarians from the same birth cohort together with NT-proBNP measurements and followed all participants over 7 years. We found that, independent of CMV serostatus, a high number of CD27−CD28+ CD8 EMRA...
No difference was found upon the frequency of CD4+CD27+CD28+ T cells between patients with chronic HBV and healthy control, ie, (±)% vs (±)% (). Conclusions Both CD4+ and CD8+ T lymphocytes in healthy control demonstrate a clear enrichment of the early differentiation phenotype. ...
抗CD28兔单克隆抗体流式鉴定 Figure 3. Affinity ranking of different Rabbit anti-CD27 mAb clones by titration of different concentration onto Raji cells. The Y-axis represents the mean fluorescence intensity (MFI) while the X-axis represents the concentration of Ig...
CD27 is the principle determinant for accumulation of virus-specific T cells in the lung because it can sustain this response in CD28(-/-) mice. Unlike CD28, CD27 does not affect cell cycle activity, but promotes survival of activated T cells throughout successive rounds of division at the...
IL-21 promotes the expansion of CD27+CD28+ tumor infiltrating lymphocytes with high cytotoxic potential and low collateral expansion of regulatory T cells D.IL-21 promotes the expansion of CD27+CD28+ tumor infiltrating lymphocytes with high cytotoxic potential and low collateral expansion of ...
We investigated the role of CD27 on resting and memory CD4+ T cells. We isolated human CD4+CD45RA+ and CD4+CDRO+ subsets using Dynal magnetic beads and cultures were set up by cross-linking with antibodies as indicated: CD3 + CD28; CD27 alone; CD27 + CD3; CD27 + CD28; CD28 alone...
