Sustained Vaccine Exposure Elicits More Rapid, Consistent, and Broad Humoral Immune Responses to Multivalent Influenza Vaccines

Advanced Science, EarlyView.
This work presents an injectable polymer‐nanoparticle hydrogel depot platform for delivering multivalent influenza vaccines which induces stronger and more durable immune responses. The technology provides broader protection, including against heterologous and potential pandemic strains (H5N1, H7N9, H9N2), and enhances the effectiveness of commercial ...

Modelling the drivers of the spread of Plasmodium falciparum hrp2 gene deletions in sub-Saharan Africa

eLife, 2017
Rapid diagnostic tests (RDTs) have transformed malaria diagnosis. The most prevalent P. falciparum RDTs detect histidine-rich protein 2 (PfHRP2). However, pfhrp2 gene deletions yielding false-negative RDTs, first reported in South America in 2010, have ...

Shrimp Virus Regulates ROS Dynamics via the Nrf2 Pathway to Facilitate Viral Replication

Advanced Science, EarlyView.
Viruses manipulate host ROS as a strategy to achieve successful infection. WSSV exploits Nrf2 pathway to maintain ROS homeostasis and establishes a positive feedback loop to facilitate WSSV replication. Wsv220 competitively binds to Keap1 to activate Nrf2. Nrf2 up‐regulates LvG6PDH to produce more NADPH and GSH to eliminate excessive ROS.

Advancing the Identification of Bioactive Molecules and the Construction of a Synergistic Drug Delivery System in Combating Lung Injury

Advanced Science, EarlyView.
Traditional Chinese Medicine (TCM), while holistic and historically esteemed, faces challenges in “miracle cures” due to slow onset, long cycles, and difficulty controlling quality. This study obtains the active ingredients, glabridin (GLA) and puerarin (PUE), from Ge‐Gen Decoction (GGD), developing a safe and effective drug delivery system, GLA‐PUE ...

Immunity Debt for Seasonal Influenza After the COVID‐19 Pandemic and as a Result of Nonpharmaceutical Interventions: An Ecological Analysis and Cohort Study

Advanced Science, EarlyView.
This study provides support for the immunity debt hypothesis, revealing a 131.72% increase in influenza rates during winter and a 161.23% rise in summer, 1 year following the global easing of COVID‐19 restrictions. This study offers empirical evidence of immunity debt on a global level, highlighting the importance of incorporating this concept into the
