Dictyostelium Chemotaxis: Fascism Through the Back Door?
Dictyostelium discoideum cells undergo a major lifestyle change when they get hungry. They grow as unicellular amoebas, but when food starts to get short they aggregate into masses of up to a million cells, which in turn differentiate and sort out into mushroomshaped fruiting bodies. Aggregation and differentiation are rigorously controlled by a multitude of signalling pathways, which together ...
متن کاملSneaking in through the back door
Over recent decades, the numerous coronary revascularisation procedures performed either by percutaneous coronary intervention (PCI), or coronary bypass surgery has led to an increasing number of patients who are no longer eligible for additional revascularisation procedures. This number of patients is expected to rise even further in view of an increase in life expectancy in patients with coro...
متن کاملLeucine biosynthesis in fungi: entering metabolism through the back door.
After exploring evolutionary aspects of branched-chain amino acid biosynthesis, the review focuses on the extended leucine biosynthetic pathway as it operates in Saccharomyces cerevisiae. First, the genes and enzymes specific for the leucine pathway are considered: LEU4 and LEU9 (encoding the alpha-isopropylmalate synthase isoenzymes), LEU1 (isopropylmalate isomerase), and LEU2 (beta-isopropylm...
متن کاملAdenovirus takes the back door
The real role of reelin ttractants and repellents shunt neurons into their correct final location. But now Iris Hack, Harold Cremer (Université Mediterranée, Marseille, France), and colleagues have found evidence that reelin fits into neither of these categories. They propose, instead, that reelin converts cells that are migrating in association with each other into individual cells that can st...
متن کاملCa2+ chemotaxis in Dictyostelium discoideum.
Using a newly developed microfluidic chamber, we have demonstrated in vitro that Ca(2+) functions as a chemoattractant of aggregation-competent Dictyostelium discoideum amoebae, that parallel spatial gradients of cAMP and Ca(2+) are more effective than either alone, and that cAMP functions as a stronger chemoattractant than Ca(2+). Effective Ca(2+) gradients are extremely steep compared with ef...
