The discovery of broadly protective antibodies to the influenza virus neuraminidase (NA) has raised interest in NA as a vaccine target. However, recombinant, solubilized tetrameric NA ectodomains are often challenging to express and isolate, hindering the study of anti-NA humoral responses. To address this obstacle, we established a panel of 22 non-adherent cell lines stably expressing native, historical N1, N2, N3, N9, and NB NAs anchored on the cell surface.

Despite its potential, the pharmacokinetics and safety profile of intravenous (IV) fosfomycin, particularly its penetration into the lower respiratory tract, are unknown. To address this gap, we conducted a Phase 1, open-label trial to assess the safety and pulmonary pharmacokinetics of IV fosfomycin in healthy participants.

Objective: To compare the proportions of hospitalized preterm infants with apnea and other adverse events in the 48 hours after 2-month vaccinations vs after no vaccinations.
Article Synopsis
- Pandemic influenza vaccine development emphasizes the importance of hemagglutinin (HA) and neuraminidase (NA) antibodies for effective immune responses.
- Clinical trials show that NA inhibition antibody responses increase with higher doses and extended intervals between vaccine doses, indicating a potential strategy for enhancing immunity.
- The study indicates that while neuraminidase responses can be improved for better pandemic preparedness, the antibody responses to the HA stalk were minimal and not long-lasting.
