Activation of presynaptic receptors for a variety of neurotransmitters and neuromodulators
inhibits transmitter release at many synapses. Such presynaptic inhibition might serve as a …

Neurotransmitters acting through G-protein-coupled receptors change the electrical
excitability of neurons. Activation of receptors can affect the voltage dependence, the speed …

THE mixed-lineage leukaemia gene (MLL/HRX/ALL-1) is disrupted by chromosomal
translocation in human acute leukaemias that often display mixed lymphoid–myeloid …

Innate social behaviours emerge from neuronal circuits that interpret sensory information on
the basis of an individual's own genotype, sex and experience. The regulated aggregation …

Abstract NEUROPEPTIDE Y (NPY), a 36-amino-acid transmitter distributed throughout the
nervous system1, 2, is thought to function as a central stimulator of feeding behaviour1–4 …

Energy stores are held relatively constant in many mammals. The circuitry necessary for
maintaining energy homeostasis should (1) sense the amount of energy stored in adipose …

From the secretion of neurotransmitters via synaptic vesicles to the expulsion of cellular
waste via contractile vacuoles, exocytosis and its sequel, endocytosis, are being explored …

A method was designed for in vivo observation of sieve element/companion complexes by
using confocal laser scanning microscopy. A leaf attached to an intact fava bean plant was …

Calcium influx into any cell requires fine tuning to guarantee the correct balance between
activation of calcium-dependent processes, such as muscle contraction and …

▪ Abstract Activation of different types of G-protein-linked and ionotropic presynaptic
receptors has been shown to regulate neurotransmitter release throughout the central and …
