Biochemical Pharmacology, 2008
Apoptosis is a genetically programmed and physiological mode of cell death that leads to the removal of unwanted or abnormal cells. Cysteine-proteases called caspases are responsible for the apoptotic execution phase which is characterized by specific biochemical events as well as morphological changes.

Comprehensive Physiology, 2012
Abstract Cilia and flagella are surface‐exposed, finger‐like organelles whose core consists of a microtubule (MT)‐based axoneme that grows from a modified centriole, the basal body. Cilia are found on the surface of many eukaryotic cells and play important roles in cell motility and in coordinating a variety of ...

Experientia, 1995
New avenues of cytoskeleton research in Dictyostelium discoideum have opened up with the cloning of the alpha- and beta-tubulin genes and the characterization of kinesins and cytoplasmic dynein. Much research, however, continues to focus on the actin cytoskeleton and its dynamics during chemotaxis, morphogenesis, and other motile processes.

Thrombosis and Haemostasis, 1993
SummaryThe platelet cytoskeleton contains two actin filament-based components. One is the cytoplasmic actin filaments which fill the cytoplasm and mediate contractile events. The other is the membrane skeleton, which coats the plasma membrane and regulates properties of the membrane such as its contours and stability. In the unstimulated platelet, only

Publisher Summary This chapter summarizes the results obtained in capping/cytoskeleton research. There are two types of capping phenomena: ligand-dependent and ligand-independent processes. A number of different reagents, such as colchicine and hypertonic media, can cause the formation of cap structures in the absence of any externally added ligand ...

Annual Review of Genetics, 2010
Bacteria, like eukaryotes, employ cytoskeletal elements to perform many functions, including cell morphogenesis, cell division, DNA partitioning, and cell motility. They not only possess counterparts of eukaryotic actin, tubulin, and intermediate filament proteins, but they also have cytoskeletal elements of their own.

The Cytoskeleton of trypanosomes
Parasitology Today, 1990From the concept of cells as mere bags full of enzymes, cell biology has come a long way towards understanding the highly complex structural organization of eukaryotic cells. The cytoskeleton, ie. the complex of fibrous elements that are crucial for cell shape, motility and the structural organization of cytoplasm and cell membranes, is now recognized ...

Current Opinion in Cell Biology, 2008
Bacteria contain a complex cytoskeleton that is more diverse than previously thought. Recent research provides insight into how bacterial actins, tubulins, and ParA proteins participate in a variety of cellular processes.

Current Opinion in Cell Biology, 1991
Significant progress has been made in four areas: in appreciating the speed with which cortical microtubules reorient in response to environmental signals; in a consolidated understanding of the cytoskeletal nature of the phragmosome--the device that predicts and structures the division plane in vacuolated cells; in the description of new cytoskeletal ...

Current Opinion in Cell Biology, 1994
Particles that can nucleate microtubules in vitro have been isolated from higher plant cells. Observations of living cells injected with fluorescent probes have improved our understanding of plant cytoskeleton dynamics. Despite growing recognition of the need for biochemical studies on cytoskeleton-associated proteins, little progress has been made in ...
