In vitro study demonstrates that modulating lipid droplet catabolism enhances cytotoxicity in developing neutrophils, highlighting metabolic strategies for cell therapy.

Key Points

To profile lipid droplet dynamics during neutrophil development using stimulated Raman scattering microscopy and determine how modulating lipid droplet metabolism influences mature neutrophil immune functions.
Quantified label-free lipid droplet accumulation across murine Hoxb8 myeloid progenitors and human pluripotent stem cell-derived neutrophils using stimulated Raman scattering microscopy.
Pharmacologically targeted lipid droplet biosynthesis and catabolism, including inhibition of adipose triglyceride lipase (ATGL), across stage-specific differentiation.
Assessed differentiation efficiency, lineage commitment, reactive oxygen species (ROS) generation, and anti-tumor cytotoxicity against GL261 and U87MG glioma cells.
Perturbation of lipid droplet metabolism altered mature neutrophil functional output without impairing differentiation efficiency, lineage commitment, or cell yield.
Inhibition of ATGL-mediated lipid breakdown selectively increased intracellular lipid droplet accumulation and elevated reactive oxygen species production in both murine and human neutrophils.
ATGL inhibition enhanced anti-tumor cytotoxicity against murine GL261 glioma cells, with a less pronounced cytotoxic increase against human U87MG glioblastoma cells.
