Transmitted by the tsetse fly, Trypanosoma brucei is a protozoan parasite that causes sleeping sickness in human and nagana in cattle. While infecting the bloodstream and central nervous system, T. brucei evades the immune system by altering its major surface antigen, Variant Surface Glycoproteins (VSGs), which forms a thick coat on its cell membrane. The expression sites for VSGs are at the sub-telomeric regions of T. brucei chromosomes. Telomeres, DNA-protein complexes located at the end of chromosomes, provide chromosome stability by preventing degradation of the chromosome ends. The telomere complex also regulates the sub-telomeric VSG expression and switching in T. …
