Neutrophil influx to sites of mycobacterial infections is one of the first events of tuberculosis pathogenesis. However, the role of early neutrophil recruitment in mycobacterial infection is not completely understood. We investigated the rate of neutrophil apoptosis and the role of macrophage uptake of apoptotic neutrophils in a pleural tuberculosis model induced by BCG. Recruited neutrophils were shown to phagocyte BCG and a large number of neutrophils undergo apoptosis within 24 h. Notably, the great majority of apoptotic neutrophils were infected by BCG. Increased lipid body (lipid droplets) formation, accompanied by prostaglandin E₂ (PGE₂) and TGF‐β1 synthesis, occurred in parallel to macrophage uptake of apoptotic cells. Lipid body and PGE₂ formation was observed after macrophage exposure to apoptotic, but not necrotic or live neutrophils. Blockage of BCG‐induced lipid body formation significantly inhibited PGE₂ synthesis. Pre‐treatment with the pan‐caspase inhibitor zVAD inhibited BCG‐induced neutrophil apoptosis and lipid body formation, indicating a role for apoptotic neutrophils in macrophage lipid body biogenesis in infected mice. In conclusion, BCG infection induced activation and apoptosis of infected neutrophils at the inflammatory site. The uptake of apoptotic neutrophils by macrophages leads to TGF‐β1 generation and PGE₂‐derived lipid body formation, and may have modulator roles in mycobacterial pathogenesis.
