Triple punch against trypanosomes
Fat cooperation keeps sleeping sickness at bay, say Molina-Portela et al. (page 1721). The authors find that all three components of a human high density cholesterol complex are needed to kill disease-causing trypanosomes. Trypanosomes cannot synthesize their own fats, so they feed on the host's portion, which in humans and some other primates includes a cholesterol complex known as the trypano...
متن کاملBiodiversity of avian trypanosomes.
We have studied the biodiversity of trypanosomes from birds and bloodsucking Diptera on a large number of isolates. We used two molecular approaches, random amplification of polymorphic DNA (RAPD) method, and sequence analysis of the small subunit ribosomal RNA (SSU rRNA) gene. RAPD method divided the isolates into 11 separate lineages. Phylogenetic analysis of the SSU rRNA gene was congruent w...
متن کاملTrypanosomes show their commitment
Pek et al. describe how a stable, intron-derived RNA regulates the expression of its host gene during Drosophila embryogenesis. Once they are spliced out of nascent mRNAs, noncoding intron sequences are usually degraded rapidly. At least in Xenopus eggs and human cell lines, however, some intronic RNAs persist for long periods, although the function of these stable intronic sequence (sis) RNAs ...
متن کاملElectrophoretic Behaviour of Trypanosomes
Prothidium caused gross loss of motility and clumping of all trypanosomes. Comparison of the findings for trypanosomes with those for other cells previously studied shows that T. Iewi8i iS very similar electrophoretically to freely circulating cells such as lymphocytes and tumour cells. On the other hand, the surface properties of the blood-stream form of T. rhodesiense are different electropho...
متن کاملTrypanosomes at the gates.
L ike many colleagues, I sometimes thought I'd never see the day when three small parasites would be so celebrated. After all, why should people outside of the small cohort of dedicated scientists and sponsors pay any attention to these " Tritryps " —Trypanosoma brucei, Trypanosoma cruzi, and Leishmania major— whose genomes appear in this issue of Science? These three motile, unicellular, nucle...
