The parasite Trypanosoma brucei can exploit antigenic variation of its VSG coat proteins to avoid detection by the mammalian host. In the December 13 Nature, Miguel Navarro and Keith Gull from the University of Manchester, UK, provide a mechanism for mono-allelic VSG expression (Nature 2001, 409:759-763).
