title: Macrophages in immunobiology.
abstract: Macrophages are now known to be important not only in resistance to infection but also in immunoregulation, in resistance to tumours and as secretory cells. Among problems requiring further investigation are the ways in which they destroy intracellular organisms, the ways in which they recognize and destroy tumour cells and the extent of their heterogeneity.
