• BMS 309403: From FABP4 Biology to Translation

  2026-08-13

  FABP4 is increasingly understood as a signaling node linking fatty acid handling, macrophage inflammation, foam cell formation, and metabolic dysfunction. This thought-leadership article interprets recent SERCA2–calcineurin–FoxO1–FABP4 findings through a translational lens and positions BMS 309403 as a selective pharmacological tool for testing pathway causality. It also outlines experimental controls, workflow parameters, model-selection logic, and the limitations researchers should address before connecting mechanistic observations to therapeutic hypotheses.

• Structural Insights into CD38 CAR Affinity Tuning

  2026-08-13

  The iScience study dissects how the CD38 CAR binders RP02 and 028 recognize distinct antigen surfaces and alter CD38 enzymatic function. Its combination of structural analysis, alanine scanning, and CAR-T testing shows how affinity attenuation can reduce fratricide while preserving antitumor cytotoxicity.

• O-propargyl-puromycin (OPP) in B-Cell Assays

  2026-08-12

  O-propargyl-puromycin (OPP) converts a short translation pulse into a measurable signal for comparing protein synthesis across B-cell states, mitochondrial perturbations, and immune responses.
