M. Eckwalanga et al., MURINE AIDS PROTECTS MICE AGAINST EXPERIMENTAL CEREBRAL MALARIA - DOWN-REGULATION BY INTERLEUKIN-10 OF A T-HELPER TYPE-1 CD4-MEDIATED PATHOLOGY( CELL), Proceedings of the National Academy of Sciences of the United Statesof America, 91(17), 1994, pp. 8097-8101
The retrovirus LP-BM5 murine leukemia virus induces murine AIDS in C57
BL/6 mice that has many similarities with human AIDS; Plasmodium bergh
ei ANKA causes experimental cerebral malaria in the same strain of mir
e. The outcome of malaria infection was studied in mice concurrently i
nfected with the two pathogens. The retrovirus significantly reduced t
he gravity of the neurological manifestations associated with Plasmodi
um berghei ANKA infection. The protection against experimental cerebra
l malaria induced by murine AIDS increased with duration of viral infe
ction and, hence, with the severity of the immunodeficiency. Interleuk
in 10, principally from splenic T cells, was shown to play a crucial r
ole in this protection.
