Mucosal immunity is crucial for preventing the infection and transmission of respiratory viruses. Nasal antibody inversely correlated with a lower risk However, current reference standard nasal assessment serum-based, mainly consisting monomeric IgG IgA. The applicability serum-derived standards assessing antibodies, mostly dimeric or polymeric secretory IgA (sIgA), remains unvalidated. Herein, we first proved that sera-derived was not applicable antibodies. Using non-homologous as...

HIV-1 transmembrane protein gp41 plays a crucial role by forming stable six-helix bundle during HIV entry. Due to highly conserved sequence of gp41, the development an effective and safe small-molecule compound targeting is good choice. Currently, natural polyanionic ingredients with anti-HIV activities have aroused concern. Here, we first discovered that glycosylated dihydrochalcone, trilobatin, exhibited broad anti-HIV-1 activity low cytotoxicity in vitro. Site-directed mutagenesis...

Background/Objectives: Enterovirus 71 (EV71) and coxsackieviruses A16 (CA16), A10 (CA10), A6 (CA6) are the primary pathogens that cause hand, foot, mouth disease (HFMD). Currently, many manufacturers developing bivalent, trivalent, tetravalent vaccines target these antigens. Cell-based neutralization assay (CBNA), gold standard for detecting neutralizing antibodies (NtAbs), which used as indicators of HFMD vaccine efficacy, has several limitations. We aimed to develop a novel NtAbs against...

Background: The three commercial Enterovirus 71 (EV71) inactivated vaccines which have effectively controlled the EV71 pandemic currently rely on inherent variable in vivo potency methods for batch release. To align with 3R (Replacement, Reduction, Refinement) principles and enhance quality control, this study referred to WHO guidelines European Pharmacopoeia develop vitro relative (IVRP) methods. Methods: Working standards tracing phase 3 clinical were established. Manufacture-specific IVRP...
