Dictyostelium amoebae and neutrophils can swim.
Animal cells migrating over a substratum crawl in amoeboid fashion; how the force against the substratum is achieved remains uncertain. We find that amoebae and neutrophils, cells traditionally used to study cell migration on a solid surface, move toward a chemotactic source while suspended in solution. They can swim and do so with speeds similar to those on a solid substrate. Based on the surp...
متن کاملAscorbate recycling in human neutrophils: induction by bacteria.
Ascorbate (vitamin C) recycling occurs when extracellular ascorbate is oxidized, transported as dehydroascorbic acid, and reduced intracellularly to ascorbate. We investigated microorganism induction of ascorbate recycling in human neutrophils and in microorganisms themselves. Ascorbate recycling was determined by measuring intracellular ascorbate accumulation. Ascorbate recycling in neutrophil...
متن کاملThe effect of olive extract on human neutrophils
The neutrophil respiratory burst, which is essential for the host's ability to kill microorganisms, can be stimulated by some natural agents. Olea europaea (Oleaceae) is used as anti hypertensive, hyperglycemia, and hypercholestremia in traditional medicine. Here in this study, we evaluate the stimulatory effect of olive oil extract on oxidative burst in human neutrophils in vitro. Buffy coat w...

متن کاملDo cyanobacteria swim using traveling surface waves ? ( bacteria / motility ) KURT
Bacteria that swim without the benefit of flagella might do so by generating longitudinal or transverse surface waves. For example, swimming speeds of order 25 ,um/s are expected for a spherical cell propagating longitudinal waves of 0.2 ,um length, 0.02 ,um amplitude, and 160 ,im/s speed. This problem was solved earlier by mathematicians who were interested in the locomotion of ciliates and wh...
