Expression of nestin has been suggested to be a characteristic of pancreatic islet stem cells. To determine whether nestin is indeed expressed in such putative cells during embryonic development, or in the adult pancreas after injury, we performed a cell l ...
Glial cell line-derived neurotrophic factor (GDNF), a potent neurotrophic factor with restorative effects in a variety of rodent and primate models of Parkinson's disease (PD), could be of therapeutic value to PD. In this study, we show that intraventricul ...
Regulation of the expression of MCT1 and MCT2, two isoforms of the monocarboxylate transporter (MCT) family, was investigated in primary cultures of mouse cortical neurons. Under basal conditions, both MCT immunoreactivities (IR) were found in the cell som ...
Glutamate-evoked Na+ increase in astrocytes has been identified as a signal coupling synaptic activity to glucose consumption. Astrocytes participate in multicellular signaling by transmitting intercellular Ca2+ waves. Here we show that intercellular Na+ w ...
The Notch and fibroblast growth factor (FGF) pathways both regulate cell fate specification during mammalian neural development. We have shown previously that Notch1 activation in the murine forebrain promotes radial glial identity. This result, together w ...
Evidence suggests that lactate could be a preferential energy substrate transferred from astrocytes to neurons. Such a process implies the presence of specific monocarboxylate transporters on both cell types. Expression of MCT1 and MCT2, two isoforms of th ...
Increasing evidence suggests that glutamate activates the generation of lactate from glucose in astrocytes; this lactate is shuttled to neurons that use it as a preferential energy source. We explore this multicellular "lactate shuttle" with a novel dual-c ...
The mammalian circadian timing system is composed of a central pacemaker in the suprachiasmatic nucleus (SCN) of the brain and subsidiary oscillators in most peripheral cell types. While oscillators in SCN neurons are known to function in a self-sustained ...
Synaptically released glutamate has been identified as a signal coupling excitatory neuronal activity to increased glucose utilization. The proposed mechanism of this coupling involves glutamate uptake into astrocytes resulting in increased intracellular N ...
Huntington's disease (HD) is a monogenic neurodegenerative disease that affects the efferent neurons of the striatum. The protracted evolution of the pathology over 15 to 20 years, after clinical onset in adulthood, underscores the potential of therapeutic ...
