The inflammasome is one of the few innate pathways that destroys the cell it activates. A macrophage that assembles NLRP3 has committed to a decision it cannot reverse: a priming signal through TLR4

In most solid tumours the largest immune population is not a T cell. It is a myeloid cell that has been recruited, expanded and re-educated by the tumour itself. Tumour-associated macrophages and mye

A macrophage does not decide to eat; it counts votes. Every particle it touches carries a mixture of pro-phagocytic and inhibitory ligands, and engulfment follows only when the activating tally clear
