Radiotelemetric and genetic studies of peripheral tissue response show that a peripheral tissue can dynamically alter cardiovascular adaptation to changes in environmental oxygen.
The hepatic endocannabinoid/CB1R system controls the soluble leptin receptor’s expression and/or subsequent release by Trib3-induced regulation of C/EBP homologous protein levels in hepatocytes to affect leptin signaling in the liver.
Molecular labeling, electrophysiology and calcium imaging have revealed a novel switching of neurotransmitter at the frog neuromuscular junction where motoneurons transiently release glutamate before acetylcholine at synapses on developing hindlimb muscles at the onset of metamorphosis.
Genetic mouse models identify a critical mechanism of myogenic vasoconstriction and reveal the in vivo function of myogenic autoregulation in protecting from organ overperfusion and in maintaining vascular resistance.
Primary cilia on endothelial cells are required for VEGF-A/ VEGFR2-dependent signaling, islet vascularization and, consequently, nutrient delivery and insulin disposal.
Under conditions where the force of HIV infection per cell is high, partial attenuation of infection with inhibitors can increase the number of live infected cells and may paradoxically be beneficial for viral spread.
Experiments reveal mechanisms through which Caenorhabditis elegans zygotes depleted of Aurora A or lacking centrosomes spontaneously establish two posterior PAR-2 domains, one at each pole, in a curvature-dependent manner.
No single molecular change is uniquely necessary to cause neuropathic changes in primary afferent excitability; multiple different changes are sufficient.
