The directional migration of cells within multicellular organisms is governed by gradients of both chemical attractants and… Expand Large proton fluxes accompany cell migration, but their precise role remains unclear. We studied pH regulation during the course… Expand Swimming cells of Sinorhizobium meliloti are driven by flagella that rotate only clockwise. They can modulate rotary speed… Expand BACKGROUND
Chemotaxis is defined as directional cell movement of cells towards concentration gradients of solubilized attractants… Expand Eosinophils play an important role in the pathogenesis of allergic diseases such as allergic asthma. Eosinophil migration in… Expand The swimming behaviour of laboratory-reared newly hatched cod larvae (Gadus morhua L.) was observed in a control solution of… Expand Observations of free-swimming and antibody-tethered Azospirillum brasilense cells showed that their polar flagella could rotate… Expand A 48 well chemotaxis microchamber, originally designed for use with polycarbonate filters, was used with nitrocellulose filters… Expand Neutrophil locomotion was evaluated in three groups of periodontal patients, localized juvenile periodontitis (LJP), post… Expand Intracellular recordings show that (i) paramecia hyperpolarize slightly in attractants and depolarize in repellents that depend… Expand
