Invariant surface proteins in bloodstream forms of Trypanosoma brucei.
Antigenic variation of the glycoprotein forming the coat of African trypanosomes has been a dominant field of investigation for many years. The extravagant potential of these parasites to change their surface coat has destroyed hopes for a vaccine based on the variant surface glycoprotein. Recently, there has been a rising interest in the characterization of surface proteins that are not subject to antigenic variation. In this review, Peter Overath, Maliha Chaudhri, Dietmar Steverding and Karl Ziegelbauer summarize the present evidence for the occurrence, cellular localization and function of invariant surface proteins in Trypanosoma brucei.
