Abstract:
Radiation damages many cellular components and disrupts cellular functions, and was previously reported to impair locomotion in the model organism Caenorhabditis elegans. However, the response to even higher doses is not clear. First, to investigate the effects of high-dose radiation on the locomotion of C. elegans, we investigated the dose range that reduces whole-body locomotion or leads to death. Irradiation was performed in the range of 0–6 kGy. In the crawling analysis, motility decreased after irradiation in a dose-dependent manner. Exposure to 6 kGy of radiation affected crawling on aga

Abstract:
The release of free cytosolic calcium is a secondary messenger for many cell functions. Here we study the coupling between the release of intracellular calcium and motility responses of the human neutrophil. Two groups of motility responses are studied: motility responses in the presence of adhesion, such as cell crawling and phagocytosis, and motility responses ‘in suspension’, such as pseudopod formation. The motility responses are stimulated by the chemoattractant N-formyl-methionyl-leucyl-phenylalanine (fMLP) and the release of calcium is monitored by measuring the fluorescence from fluo-3

Abstract:
In this work, we quantitatively compare computer simulations and existing cell tracking data of P. aeruginosa surface motility in order to analyse the underlying motility mechanism. We present a three dimensional twitching motility model, that simulates the extension, retraction and surface association of individual Type IV Pili (TFP), and is informed by recent experimental observations of TFP. Sensitivity analysis is implemented to minimise the number of model parameters, and quantitative estimates for the remaining parameters are inferred from tracking data by approximate Bayesian computatio

Abstract:
Sperm of the nematode, Ascaris suum, crawl using lamellipodial protrusion, adhesion and retraction, a process analogous to the amoeboid motility of other eukaryotic cells. However, rather than employing an actin cytoskeleton to generate locomotion, nematode sperm use the major sperm protein (MSP). Moreover, nematode sperm lack detectable molecular motors or the battery of actin-binding proteins that characterize actin-based motility. The Ascaris system provides a simple ‘stripped down’ version of a crawling cell in which to examine the basic mechanism of cell locomotion independently of other

Abstract Although it is well established that stromal intercellular adhesion molecule-1 (ICAM-1), ICAM-2, and vascular cell adhesion molecule-1 (VCAM-1) mediate lymphocyte recruitment into peripheral lymph nodes (PLNs), their precise contributions to the individual steps of the lymphocyte homing cascade are not known. Here, we provide in vivo evidence for a selective function for ICAM-1 > ICAM-2 > VCAM-1 in lymphocyte arrest within noninflamed PLN microvessels. Blocking all 3 CAMs completely inhibited lymphocyte adhesion within PLN high endothelial venules (HEVs). Postarrest extravasatio

Abstract:
The locomotion of many soft-bodied animals is driven by the propagation of rhythmic waves of contraction and extension along the body. These waves are classically attributed to globally synchronized periodic patterns in the nervous system embodied in a central pattern generator (CPG). However, in many primitive organisms such as earthworms and insect larvae, the evidence for a CPG is weak, or even non-existent. We propose a neuromechanical model for rhythmically coordinated crawling that obviates the need for a CPG, by locally coupling the local neuro-muscular dynamics in the body to the mecha

Abstract:
If a bacterium has motility, it will use the ability to survive and thrive. For many pathogenic species, their motilities are a crucial virulence factor. The form of motility varies among the species. Some use flagella for swimming in liquid, and others use the cell-surface machinery to move over solid surfaces. Spirochetes are distinguished from other bacterial species by their helical or flat wave morphology and periplasmic flagella (PFs). It is believed that the rotation of PFs beneath the outer membrane causes transformation or rolling of the cell body, propelling the spirochetes. Interest

Abstract:
Three different models of motile systems are studied: a vibrating legged robot, a snake-like locomotor, and two kinds of agellar microswimmers. The vibrating robot crawls by modulating the friction with the substrate. This also leads to the ability to switch direction of motion by varying the vibration frequency. A detailed account of this phenomenon is given through a fully analytical treatment of the model. The analysis delivers formulas for the average velocity of the robot and for the frequency at which the direction switch takes place. A quantitative description of the mech

Abstract:
Abstract Cellular locomotion takes on many forms—from macrophage tracking and capturing a bacterium during infection to platelet spreading during blood clotting to tumour cell crawling during metastasis to cells dividing during mitosis or meiosis, but the common element is exquisitely choreographed directed movement. There are literally hundreds of proteins and enzymes involved in cell motility, and many of these proteins have multiple and often redundant roles in promoting specific types of motility (e.g. lamellipodial versus filipodial extension). The challenge then for cell biologists is to

Abstract:
Abstract The crawling of the neutrophil is essential for its physiological and pathological activity. The neutrophil crawls by projecting pseudopods in the direction of a higher chemoattractant concentration in a process known as chemotaxis. In this process, the cell initially adheres tightly to the present substrate and then rearranges its cytoskeleton. Finally, the ceil body contracts, which results in cell movement. The rearrangement of the cytoskeleton is believed to be a crucial component of cell motility (Cunningham et al., 1992) which determines the overall rate of crawling (Zigmond, 19
