P2X7 is an extracellular adenosine 5′-triphopshate (ATP)-gated cation channel present on leukocytes, where its activation induces pro-inflammatory cytokine release and ectodomain shedding of cell surface molecules. Human P2X7 can be partially inhibited by amiloride and its derivatives at micromolar concentrations. This study aimed to screen a library of compounds derived from amiloride or its derivative 5-(N,N-hexamethylene) amiloride (HMA) to identify a potential P2X7 antagonist. 6-Furopyridine HMA (6-FPHMA) was identified as a novel P2X7 antagonist and was characterized further. 6-FPHMA im...

In a recent study posted to the bioRxiv* preprint server, researchers explored the cross-reactivity, avidity, and kinetics of memory B-cells and serum antibodies in vaccinated and severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infected individuals.

In this interview, News-Medical talks to Dr. Amy Sheng and Dr. Lurong Pan about how AI computing can be used in combination with high throughput production and screening to enhance the development process for potential universal vaccines.

Researchers investigated whether the time of booster vaccination relative to SARS-CoV-2 infection is a crucial determinant of the elicited immune response; in particular, the antibody and B-cell responses.

In a recent study posted to bioRxiv*, researchers at Washington University School of Medicine, St. Louis, demonstrated that severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) vaccine booster elicits robust germinal center (GC) B cell responses.
