Antigenic Variation in Trypanosoma Brucei: Facts, Challenges and Mysteries

Curr Opin Microbiol. 2004 Aug;7(4):369-74. doi: 10.1016/j.mib.2004.05.001.

Abstract

Antigenic variation allows African trypanosomes to develop chronic infections in mammalian hosts. This process results from the alternative occurrence of transcriptional switching and DNA recombination targeted to a telomeric locus that contains the gene of the variant antigen and is subjected to mono-allelic expression control. So far, the identification of mechanisms and factors involved still resists technological developments and genome sequencing.
