Immunity of animals correlated with the destructive ability of their macrophages. Intraperitoneal inoculation of T. gondii led to a very limited infection of macrophages from immune mice. This infection was next rapidly and completely inhibited. Conversely, macrophages from mice immunized with killed toxoplasma were massively invaded and evolved like(More)
The M2 form of pyruvate kinase (M2-PK) was purified from human leucocytes by a new method involving a succession of two different Dyematrex agarose chromatographies. The main step consisted of an orange dye affinity column with elution by fructose-1,6-diphosphate. This purification procedure allowed us to obtain M2-PK with a specific activity of 433 I.U./mg(More)
