Dong Wei, Yingying Chen, Xiaoqi Yu, Yang-dian Lai, Wenxin Xu, Ping Ji, Zhitao Yang, Erzhen Chen, Xinxin Zhang & Ying Wang
BBIBP-CorV exerts efficient protection against SARS-CoV-2 infection. However, waning vaccine-induced humoral immune responses after two-dose vaccination has significantly undermined durable immuno-protection. In this study, we have demonstrated that although anti-spike (S) antibody responses in BBIBP-CorV vaccinees exhibited three serotypes after 6 months including de novo sero-negative, sero-positive and sero-decay features, S-specific interferon-γ release as well as Th1 cytokine production in CD4+ and CD8+ T cells were comparable, especially in vaccinees without detectable neutralizing antibodies. Notably,...

Adjunctive Zoledronate+IL-2 administrations enhance anti-tuberculosis Vγ2Vδ2 T-effector populations, and improve treatment outcome of multidrug-resistant tuberculosis.

Hongbo Shen, Enzhuo Yang, Ming Guo, Rui Yang, Guixian Huang, Ying Peng, Wei Sha, Feifei Wang & Ling Shen
Multidrug-resistant tuberculosis(MDR-TB) is a refractory disease with high mortality rate due to no or few choices of antibiotics. Adjunctive immunotherapy may help improve treatment outcome of MDR-TB. Our decade-long studies demonstrated that phosphoantigen-specific Vγ2Vδ2 T cells play protective roles in immunity against TB. Here, we hypothesized that enhancing protective Vγ2Vδ2 T-effector cells could improve treatment outcome of MDR-TB. To address this, we employed clinically-approved drugs Zoledronate(ZOL) and IL-2 to induce anti-TB Vγ2Vδ2 T-effector cells as...
