AbstractRespiratory syncytial virus (RSV) poses a critical threat to infants, yet vaccine and antibody development remains challenged by safety risks and antigenic variability. Here, we present a prophylactic strategy leveraging two human neutralizing antibodies, 1A2 and 1B6, which target distinct, conserved epitopes on the RSV prefusion F (pre-F) protein. Cryo–electron microscopy (cryo-EM) structural ...
AbstractThe global prevalence and disease burden of alphaherpesviruses infections, including human-infecting viruses such as HSV-1, HSV-2, and VZV, as well as animal-infecting viruses like PRV, BHV, CHV, and FHV, highlight the unmet need for more effective and universal antiviral strategies. However, there has been no significant progress in developing broad-spectrum interventions against herpesvirus....
AbstractThe durability and protective effect of naturally acquired antibodies against hepatitis E virus (HEV) reinfection and clinical progression remain unclear in humans. In a 103-month longitudinal analysis of 7032 adult placebo recipients (aged 16 to 65 years) from a phase 3 HEV vaccine trial in China, we demonstrated that baseline anti-HEV IgG seropositivity (n = 3194) conferred over 50% higher ...
AbstractBackground Globally, an estimated 296 million individuals live with chronic hepatitis B virus (HBV) infection, carrying substantial risks of liver fibrosis, cirrhosis and hepatocellular carcinoma. Fewer than 20% of patients receiving nucleos(t)ide analogues or interferons achieve a functional cure, underscoring the urgent need for novel therapeutic strategies to improve clinical outcomes in ...
SummaryBackgroundThe measles-mumps-rubella (MMR) trivalent vaccine constitutes a cornerstone in controlling mumps incidence. However, variations in vaccination timing coupled with the gradual waning of vaccine-induced immunity have contributed to an increase in mumps cases among adolescents, alongside dynamic shifts in age distribution. This study aims to elucidate the optimal vaccination strategies ...
AbstractCombination vaccines promise to simplify immunization schedules and improve coverage, but remain technically challenging owing to antigen compatibility, immunogenic balance and formulation complexity. Here we report a modular strategy that uses a single-component nanobody binder to noncovalently attach diverse antigens to intact particles from the licensed hepatitis E vaccine. To identify a ...
AbstractBackground: Nasopharyngeal carcinoma (NPC) is notably prevalent in southern China and Southeast Asia, highlighting the need for effective screening strategies. Methods: In Zhongshan, Guangdong, a screening program involving 24,852 healthy Cantonese individuals aged 30-69 compared the Anti-BNLF2b total antibody (P85-Ab) with the EBNA1-IgA and VCA-IgA testing (two-antibody method). We examined ...
