Abstract:  Objective] To investigate the role of TNF α and ICAM 1 in the pathogenesis of cerebral malaria. [Methods] Immunohistochemical method and ELISA were employed to examine the expression of ICAM 1 on the brain microvessel endothelium and to detect the production of serum TNF α in P berghei ANKA strain infected CBA/J mice. [Results] Serum TNF αlevels of mice were apparently higher and the ICAM 1 expression was more evident in P berghei ANKA infected CBA/J mice than in control groups. rTNF α ip injection could enhance the development of CM and the expression of ICAM 1 on brain endothelial cells(EC). [Conclusion] Excessive production of TNF α may mediate the expression of ICAM 1 on brain EC and hence cause the development of CM.

Key words: Cerebral malaria(CM), ICAM-1, TNF-α, Plasmodium berghei.
