The nutrients available in some tumors and the factors that influence tumor nutrient availability are characterized, which provides insight into the metabolic constraints of the tumor microenvironment.
Although central nervous system (CNS) regeneration has been considered to be controlled by CNS microenvironment, CNS injury causes leading to leakage of circulating factors into CNS, which promotes CNS regeneration.
A characterization of LGN-V1 synaptic transmission properties demonstrates thalamocortical synapses in vivo are weak and unreliable, but biologically constrained models show they efficiently drive cortex.
Expression of a Dravet syndrome-associated mutation in inhibitory neurons disrupts activity of brainstem respiratory neurons and diminishes respiratory behavior in conjunction with seizures and premature death.
Discs large homologue 1 (Dlg1) activates beta-catenin (i.e., canonical Wnt) signaling in CNS endothelial cells to regulate retinal angiogenesis and the development and maintenance of the blood-brain and blood-retina barriers.
