The pathogenicity and growth of the parasite are intimately linked to its shape and form. This is in turn derived from a highly ordered microtubule cytoskeleton that forms a tightly arrayed cage directly beneath the pellicular membrane and numerous other cytoskeletal structures such as the flagellum. The parasite undergoes extreme changes in cellular morphology during its life cycle and cell cycles which require a high level of integration and coordination of cytoskeletal processes. -

Communicating Biochemistry: Meetings and Events
© The Authors. Volume compilation © 2011 Portland Press Limited Chapter 3 Communicating Biochemistry: Meetings and Events Ian Dransfield and Brian Beechey Scientific conferences organized by the Biochemical Society represent a key facet of activity throughout the Society’s history and remain central to the present mission of promoting the advancement of molecular biosciences. Importantly, scientific conferences are an important means of communicating research findings, establishing collaborations and, critically, a means of cementing the community of biochemical scientists together. However, in the past 25 years, we have seen major changes to the way in which science is communicated and also in the way that scientists interact and establish collabo- rations. For example, the ability to show videos, “fly through” molecular structures or show time-lapse or real-time movies of molecular events within cells has had a very positive impact on conveying difficult concepts in presentations. However, increased pressures on researchers to obtain/maintain funding can mean that there is a general reluctance to present novel, unpublished data. In addition, the development of email and electronic access to scientific journals has dramatically altered the potential for communi- cation and accessibility of information, perhaps reducing the necessity of attending meetings to make new contacts and to hear exciting new science. The Biochemical Society has responded to these challenges by progressive development of the meetings format to better match the -
An Essential Role for the Leishmania Major Metacaspase in Cell Cycle Progression
Cell Death and Differentiation (2008) 15, 113–122 & 2008 Nature Publishing Group All rights reserved 1350-9047/08 $30.00 www.nature.com/cdd An essential role for the Leishmania major metacaspase in cell cycle progression A Ambit1, N Fasel3, GH Coombs1,2,4 and JC Mottram*,1,2 Metacaspases (MCAs) are distant orthologues of caspases and have been proposed to play a role in programmed cell death in yeast and plants, but little is known about their function in parasitic protozoa. The MCA gene of Leishmania major (LmjMCA)is expressed in actively replicating amastigotes and procyclic promastigotes, but at a lower level in metacyclic promastigotes. LmjMCA has a punctate distribution throughout the cell in interphase cells, but becomes concentrated in the kinetoplast (mitochondrial DNA) at the time of the organelle’s segregation. LmjMCA also translocates to the nucleus during mitosis, where it associates with the mitotic spindle. Overexpression of LmjMCA in promastigotes leads to a severe growth retardation and changes in ploidy, due to defects in kinetoplast segregation and nuclear division and an impairment of cytokinesis. LmjMCA null mutants could not be generated and following genetic manipulation to express LmjMCA from an episome, the only mutants that were viable were those expressing LmjMCA at physiological levels. Together these data suggest that in L. major active LmjMCA is essential for the correct segregation of the nucleus and kinetoplast, functions that could be independent of programmed cell death, and that the amount of LmjMCA is crucial. The absence of MCAs from mammals makes the enzyme a potential drug target against protozoan parasites. -
