Intraflagellar transport is required for the maintenance of the trypanosome flagellum composition but not its length.
Intraflagellar transport (IFT) is required for construction of most cilia and flagella. Here, we used electron microscopy, immunofluorescence and live video microscopy to show that IFT is absent or arrested in the mature flagellum of Trypanosoma brucei upon RNA interference (RNAi)-mediated knockdown of IFT88 and IFT140, respectively. Flagella assembled prior to RNAi did not shorten, showing tha...
متن کاملIntraflagellar transport proteins cycle between the flagellum and its base.
Intraflagellar transport (IFT) is necessary for the construction of cilia and flagella. IFT proteins are concentrated at the base of the flagellum but little is known about the actual role of this pool of proteins. Here, IFT was investigated in Trypanosoma brucei, an attractive model for flagellum studies, using GFP fusions with IFT52 or the IFT dynein heavy chain DHC2.1. Tracking analysis by a...
متن کاملReflective Practice: How the World Bank Explored Its Own Biases?
While many international organisations have independent evaluations, including the International Monetary Fund (IMF) and World Health organization (WHO), uniquely the World Bank in its 2015 World Development Report sought to ascertain the potential biases that influence how its staff interpret evidence and influence policy. Here, we describe the World Bank’s study design, including experiments ...
متن کاملExtremal Length of Vector Measures
We define the extremal length of vector measures. We show the reciprocal relation between extremal distance and extremal width of vector measures.
متن کاملThe trypanosome flagellum.
Introduction African Trypanosomes are flagellated protozoan parasites that cause sleeping sickness in humans and Nagana in cattle. During its life cycle, Trypanosoma brucei alternates between an insect vector (tsetse fly) and a mammalian host. Within each of these, the parasite proliferates and undergoes separate periods of differentiation in preparation for each new host/vector environment. Th...
