| 1 | Single-shot AAV-vectored vaccine against SARS-CoV-2 with fast and long-lasting immunity显示文摘Due to the insufficient long-term protection and significant efficacy reduction to new variants of current COVID-19 vaccines,the epidemic prevention and control are still challenging.Here,we employ a capsid and antigen structure engineering(CASE)strategy to manufacture an adenoassociated viral serotype 6-based vaccine(S663V-RBD),which expresses trimeric receptor binding domain(RBD)of spike protein fused with a biological adjuvant RS09.Impressively,the engineered S663V-RBD could rapidly induce a satisfactory RBD-specific IgG titer within 2 weeks and maintain the titer for more than 4 months.Compared to the licensed BBIBP-CorV(Sinopharm,China),a single-dose S663V-RBD induced more endurable and robust immune responses in mice and elicited superior neutralizing antibodies against three typical SARS-CoV-2 pseudoviruses including wild type,C.37(Lambda)and B.1.617.2(Delta).More interestingly,the intramuscular injection of S663V-RBD could overcome pre-existing immunity against the capsid.Given its effectiveness,the CASE-based S663VRBD may provide a new solution for the current and next pandemic. | Fuhua Wu Shuang Luo Yongshun Zhang Yangsen Ou Hairui Wang Zhaofei Guo Chunting He Shuting Bai Penghui He Min Jiang Xiaoyan Chen Guangsheng Du Xun Sun | 2023 | Acta Pharmaceutica Sinica B2023，13，5： | 2 |
| 2 | Field-effect at electrical contacts to two-dimensional materials显示文摘The inferior electrical contact to two-dimensional(2D)materials is a critical challenge for their application in post-silicon very large-scale integrated circuits.Electrical contacts were generally related to their resistive effect,quantified as contact resistance.With a systematic investigation,this work demonstrates a capacitive metal-insulator-semiconductor(MIS)field-effect at the electrical contacts to 2D materials:The field-effect depletes or accumulates charge carriers,redistributes the voltage potential,and gives rise to abnormal current saturation and nonlinearity.On one hand,the current saturation hinders the devices’driving ability,which can be eliminated with carefully engineered contact configurations.On the other hand,by introducing the nonlinearity to monolithic analog artificial neural network circuits,the circuits’perception ability can be significantly enhanced,as evidenced using a coronavirus disease 2019(COVID-19)critical illness prediction model.This work provides a comprehension of the field-effect at the electrical contacts to 2D materials,which is fundamental to the design,simulation,and fabrication of electronics based on 2D materials. | Yao Guo Yan Sun Alvin Tang Ching-Hua Wang Yanqing Zhao Mengmeng Bai Shuting Xu Zheqi Xu Tao Tang Sheng Wang Chenguang Qiu Kang Xu Xubiao Peng Junfeng Han Eric Pop Yang Chai | 2021 | Nano Research2021，14，12： | 0 |
| 3 | Nanoparticles with rough surface improve the therapeutic effect of photothermal immunotherapy against melanoma显示文摘Photothermal therapy has been intensively investigated for treating cancer in recent years.However,the long-term therapeutic outcome remains unsatisfying due to the frequently occurred metastasis and recurrence.To address this challenge,immunotherapy has been combined with photothermal therapy to activate anti-tumor immunity and relieve the immunosuppressive microenvironment within tumor sites.Here,we engineered silica-based core-shell nanoparticles(JQ-1@PSNs-R),in which silica cores were coated with the photothermal agent polydopamine,and a bromodomain-containing protein 4(BRD4) inhibitor JQ-1 was loaded in the polydopamine layer to combine photo thermal and immune therapy for tumor elimination.Importantly,to improve the therapeutic effect,we increased the surface roughness of the nanoparticles by hydrofluoric acid(HF) etching during the fabrication process,and found that the internalization of JQ-1@PSNs-R was significantly improved,leading to a strengthened photothermal killing effect as well as the increased intracellular delivery of JQ-1.In the animal studies,the multifunctional nanoparticles with rough surfaces effectively eradicated melanoma via photothermal therapy,successfully activated tumor-specific immune responses against residual tumor cells,and further prevented tumor metastasis and recurrence.Our results indicated that JQ-1@PSNs-R could serve as an innovative and effective strategy for combined cancer therapy. | Jiao Xue Yining Zhu Shuting Bai Chunting He Guangsheng Du Yuandong Zhang Yao Zhong Wenfei Chen Hairui Wang Xun Sun | 2022 | Acta Pharmaceutica Sinica B2022，12，6： | 0 |
