		The trypanosomes or kinetoplastid protozoa comprise a large group of parasitic flagellated cells that are the causal agents for a variety of human and animal diseases.
		Kinetoplastid protozoa have a single mitochondrion that extends throughout the cell.
		All mitochondrial tRNAs in kinetoplastid protozoa are encoded in the nucleus and imported from the cytosol.

	Kinetoplastid Biology and Human Disease
		Kinetoplastid DNA is relatively abundant and consists of mini-circles and maxi-circles.
		However, the kinetoplastids exhibit several morphological forms which are defined by the position of the kinetoplast in relation to the nucleus and the length of the undulating membrane (see morphological forms).
		The different forms are distinguished by the position of the kinetoplastid in relation to the nucleus and the presence or absence of an undulating membrane.

	Kinetoplastid - Wikipedia, the free encyclopedia
		The kinetoplastids are a group of flagellate protozoa, including a number of parasites responsible for serious diseases in humans and other animals, as well as various forms found in soil and aquatic environments.
		There is also one family of kinetoplastids, the trypanosomes, which only have a single emergent flagellum, including several genera which are exclusively parasitic.
		The kinetoplastids were first defined by Honigberg in 1963 as the flagellate order Kinetoplastida.

	Kinetoplastid Molecular Cell Biology Meeting (Site not responding. Last check: 2007-10-12)
		Kinetoplastids are very appealing models for the study of flagellar function, particularly given the availability of extensive genome information.
		The best characterized of these is the kinetoplastid PFR which is composed of two major proteins, PFR1 and PFR2, and several minor ones, most of which are uncharacterised.
		The PFR is necessary for full motility in the kinetoplastids and provides support for metabolic regulators that may influence flagellar beating.

	New drug targets for kinetoplastid drug discovery
		Of these, only three were for treatment of diseases caused by kinetoplastid organisms: eflornithine for African trypanosomiasis, and benznidazole and nifurtimox, both for Chagas disease.
		Participants at the meeting presented work on several promising target molecules or metabolic pathways of kinetoplastids: trypanothione reductase and polyamine metabolism, farnesyl transferase and protein prenylation, sterol metabolism, topo-isomerases, proteases, and cAMP signalling pathways.
		Scientists who believe they have projects that are relevant to drug discovery for any of the kinetoplastid diseases, and for which molecular targets and/or lead molecules have been identified, are urged to contact Richard Pink for advice and information on TDR’s potential ability to advance the project.

		Analysis of kinetoplastid research literature from the last 35 years shows that 25,000 articles were published, however, during this period there has been little success in developing therapeutics, prophylactics or even cheap effective diagnostics.
		The result of this fragmentation of the research literature is that each discipline is largely ignorant of advances of the others, progress is impeded, and similar studies are often reproduced.
		Kinetoplastid Biology and Disease aims to become a focus for the whole kinetoplastid research community.

		The kinetoplastid protozoa infect hosts ranging from invertebrates to plants and mammals, causing diseases of medical and economic importance.
		Protein trafficking in kinetoplastids is in many respects similar to that in higher eucaryotes, including mammals and yeasts.
		Some components of the normal array of trafficking mechanisms may be missing in most (if not all) kinetoplastids: examples are clathrin-coated vesicles, recycling receptors, and mannose 6-phosphate-mediated lysosomal targeting.

	Genome Biology \| Full text \| A computational investigation of kinetoplastid trans-splicing
		Kinetoplastid 5' UTRs are fairly short, ranging in length from 40 to 200 nucleotides (based on a survey of GenBank entries).
		One of the challenges with gene prediction in the kinetoplastids is that the longest open reading frame present in a genomic segment does not necessarily correlate with the true open reading frame in the mRNA.
		We propose that our method might be applied to refine gene prediction in kinetoplastid genomes by assisting in the identification of the true starts of coding regions.

		The kinetoplastid protozoa comprise a large group of flagellated organisms that are thought to have had a common ancestor with the Euglenoid protozoa early in evolution of eukaryotic cells.
		There is some evidence that the common ancestor contained a plastid derived from endosymbiosis of an algae, which was secondarily lost in the kinetoplastid lineage but some of the genes of which were transferred to the nucleus.
		There are two major groups of kinetoplastid protists - the bodonids and the trypanomatids.

		Using related (kinetoplastid) protozoan parasites, Leishmania major and Trypanosoma cruzi, as models, we have demonstrated that heterologous expression of GPI-PLC can lead to a GPI deficiency, resulting in replication defects in both Leishmania and T.
		We are studying the biochemical mechanism(s) for rejection of kinetoplastid signal peptides by the mammalian translocation machinery.
		We are also cloning trypanosome homologs of the mammalian protein that displayed defective interactions with the kinetoplastid signal sequences.

		Members of the family kinetoplastidae include organisms that cause a variety of deadly parasitic diseases: (i) the African trypanosome causes sleeping sickness in humans and a corresponding disease in cattle called nagana; (ii) Chagas’ disease of Latin America caused by T.
		One of the main research goals in this laboratory is to understand how the trypanosome is able to escape the host immune system allowing the parasite to proliferate in the mammalian bloodstream and eventually cause disease.
		Our hypothesis is that the novel thymine base modification represents an epigenetic factor involved in the regulation of kinetoplastid transcription and recombination.

		Deep-sea vent samples were both cultured to select for kinetoplastid flagellates and analyzed without culturing by denaturing gradient gel electrophoresis (DGGE) using PCR primers specific to the kinetoplastid clade.
