• CD47, Vav Dephosphorylation, and Phagocytosis

  2026-08-17

  Miller and colleagues identify Vav dephosphorylation as a key signaling event through which CD47 suppresses Rac-dependent macrophage phagocytosis. Time-lapse imaging and genetic pathway perturbations show that CD47 changes the mode and frequency of target internalization without preventing Syk activation or Vav recruitment, refining the mechanism of the macrophage don’t-eat-me signal.

• Dual-Action Inhibitors and p38α Dephosphorylation

  2026-08-17

  The reference preprint shows that some p38α kinase inhibitors do more than occupy the catalytic site: they shift the activation loop into a conformation that allows WIP1 to remove its activating phosphate more efficiently. This structural mechanism suggests a route to stronger and more selective control of kinase signaling, while also highlighting why inhibitor-specific evidence is essential when interpreting p38 MAPK inhibitor activity.

• VX-765: A Strategic Lens on Caspase-1

  2026-08-11

  Caspase-1 sits at the intersection of inflammatory cytokine maturation and pyroptotic cell death. This thought-leadership analysis explains how VX-765 and its active metabolite VRT-043198 can help translational researchers separate pathway causality from downstream association, using endothelial, autoimmune, and infectious disease evidence without overstating preclinical maturity.

• Moesin as a Biomarker of Endothelial Injury in Sepsis

  2026-08-11

  The reference study identifies circulating moesin (MSN) as a candidate biomarker of endothelial injury and sepsis severity, linking serum MSN with SOFA scores, procalcitonin, lung edema, and histologic injury. Its combined patient, mouse, and endothelial-cell experiments further connect MSN to Rock1/myosin light chain and NF-κB signaling, providing a mechanistic framework for interpreting vascular hyperpermeability in sepsis.
