Aging metabolism reduces effectiveness of CAR-T cell therapy

A Ludwig Cancer Research study has discovered that the metabolic decline that accompanies aging impairs the efficacy of CAR-T cell therapy, an immunotherapy in which T cells of the immune system are taken from patients, engineered to target cancer cells and reinfused into the same patients for treatment.

Air pollution’s chemical punch alters immune markers in pregnant women, study finds

Personal exposure to nitrogen dioxide and the oxidative potential of fine particulate matter (PM2.5), but not PM2.5 mass, influenced immune biomarker levels in pregnant women. These findings suggest that the chemical reactivity of air pollutants may play a key role in maternal and fetal immune health.
