Haptoglobin and malaria.
Haptoglobin gene knockout mice and wild-type controls were infected with Plasmodium berghei ANKA or Plasmodium chabaudi. The peak parasitaemia and parasite burden were higher in Hp-/- mice than in Hp+/+ mice. The increase in spleen weight following malaria infection was smaller in Hp-/- mice than in Hp+/+ animals. The occurrence of cerebral malaria in P. berghei ANKA infection was not different in Hp gene knockout mice and their controls.
