Habitat fragmentation can have a high impact on parasitoid–ant interactions. Phorid flies are among the most important groups of natural enemies of leaf-cutting ants. We studied the effects of loss in forest cover upon phorids of the leaf-cutting a

Binding of N-formylated chemotactic peptides to specific cell surface receptors on polymorphonuclear leukocytes initiates a wide range of biological responses including migration of inflammatory cells, superoxide release, lysosomal enzyme secretion,

The co-carcinogenic compound phorbol 12-myristate 13-acetate but not its inactive analogue 4 alpha-phorbol 12,13-didecanoate causes the phosphorylation of several rabbit neutrophil polypeptides whose molecular weights and isoelectric points (pI) are

Intact rabbit neutrophils were found to express phospholipase A2 activity against [14C]oleate-labeled autoclaved Escherichia coli. Cells obtained 12–14 h rather than 4h after intraperitoneal injection of glycogen had approximately threefold higher

The addition of 1 mM ATP to rabbit peritoneal polymorphonuclear leukocytes suspended in a solution of glycerol causes a decrease in their volume by 4–17% within 3 min. The suspending medium must not only contain glycerol but be of low ionic strengt

Groups of rabbits were exposed to 1000, 5000, or 25,000 Schistosoma mansoni cercariae. Flocculating antibodies were detected by the use of somatic antigens from eggs and cercariae, and by metabolic antigens from adult worms. Flocculating antibodies a
