Drosophila morphogenesis: Orchestrating cell rearrangements
Changes in shape of individual cells need to be coordinated to generate the movements of cell groups and sheets that are so important in morphogenesis. Recent results have shown that, during Drosophila gastrulation, multiple signalling pathways act to orchestrate the complex cell rearrangements.
متن کاملPhysics of bacterial morphogenesis.
Bacterial cells utilize three-dimensional (3D) protein assemblies to perform important cellular functions such as growth, division, chemoreception, and motility. These assemblies are composed of mechanoproteins that can mechanically deform and exert force. Sometimes, small-nucleotide hydrolysis is coupled to mechanical deformations. In this review, we describe the general principle for an under...
متن کاملBacterial Cell Morphogenesis Does Not Require a Preexisting Template Structure
Morphogenesis, the development of shape or form in cells or organisms, is a fundamental but poorly understood process throughout biology. In the bacterial domain, cells have a wide range of characteristic shapes, including rods, cocci, and spirals. The cell wall, composed of a simple meshwork of long glycan strands crosslinked by short peptides (peptidoglycan, PG) and anionic cell wall polymers...
متن کاملRodZ, a new player in bacterial cell morphogenesis
Three different laboratories have now identified a new morphogenetic factor widely conserved in bacteria. The protein, RodZ, is required for assembly of the actin cytoskeleton MreB that controls cell wall synthesis and cell shape. It is not yet understood how bacteria determine their shape. Almost all bacteria are surrounded by a giant cell wall polymer called peptidoglycan that gives shape to ...
متن کاملMitochondrial shape changes: orchestrating cell pathophysiology.
Mitochondria are highly dynamic organelles, the location, size and distribution of which are controlled by a family of proteins that modulate mitochondrial fusion and fission. Recent evidence indicates that mitochondrial morphology is crucial for cell physiology, as changes in mitochondrial shape have been linked to neurodegeneration, calcium signalling, lifespan and cell death. Because immune ...
