Zeng was chosen for her contributions to understanding the cells and connections of the brain. (alleninstitute.org)
We're defining and analyzing the different cells that make up the mammalian brain to better understand how our brains work, how they develop, and what goes wrong in disease. (alleninstitute.org)
Exploring the diversity of cell types in the brain using a variety of microscopy and image processing techniq ues. (alleninstitute.org)
Investigating the neuroanatomical architecture of the brain at the population and single cell level. (alleninstitute.org)
Some compounds can serve as biochemical precursors of neuromediators, others may prevent oxidative damage to brain cells or provide them with a source of energy. (brainblogger.com)

Neuronal loss in the hippocampus, regarded as one of the basic pathological mechanisms underlying cognitive impairment, can result from Focal cerebral ischemia-reperfusion. (medindia.net)

In addition, we determined an optimum dose of injected mouse MGE cells in rodent. (ca.gov)

Cellular morphology, time-lapse imaging, and nuclear staining demonstrated that this activity occurred in mitotically active cells. (jneurosci.org)

It remains controversial as to whether CN arises from cells committed to neuronal phenotype or from bipotential cells in the periventricular matrix. (medscape.com)

Others, such as amendment/prevention of neuronal damage, manifest themselves only after prolonged use of the drug, thus making any changes in cognitive functions not so fast and not so obvious (although they can still be substantial). (brainblogger.com)

Modulation of intracellular free calcium concentration ([Ca 2+ ] i ) may be part of the signaling pathway by which both local environmental factors and cell autonomous developmental programs influence corticogenesis. (jneurosci.org)
BAG-1L Protects SH-SY5Y Neuroblastoma Cells Against Hypoxia/Re-oxygenation Through Up-Regulating HSP70 and Activating PI3K/AKT Signaling Pathway. (nih.gov)

When cells pass from S to G 2 , the nuclei migrate toward the VZ surface where mitosis occurs. (jneurosci.org)
Instead, it is a site where axons project from neuronal cell bodies in the supraoptic and paraventricular nuclei of the hypothalamus. (medscape.com)

Cell-type specific and multiscale dynamics of human focal seizures in limbic structures. (medscape.com)

Ascertaining cells' synaptic connections and RNA expression simultaneously with barcoded rabies virus libraries. (ohsu.edu)
Cerebral organoids showed high variability in neuronal content and tau expression. (researchsquare.com)
Here we describe how microRNA-regulated lentiviral vectors can be used to visualize specific cell populations by exploiting endogenous microRNA expression patterns. (lu.se)
When a microRNA is present in the cell, it binds to the target sites and downregulates GFP expression, while in cells that do not express the microRNA GFP, it is expressed. (lu.se)
These cells can be characterized in their developmental progression by changes in expression of 3 cell surface markers: CD4, CD8, and the T-cell receptor (TCR)-CD3 complex. (medscape.com)

The research changed the then dogma of biology, which suggested that all cells in the body shared the same genome. (wikipedia.org)

Cancerous cells undergo major changes in lipid metabolism, meaning that lipids play a major role in the proliferation of cancerous tumours. (sanbio.nl)

Indeed, granule cells from the rostral region of perinatal Gpr56 −/− cerebella show loss of adhesion to extracellular matrix molecules of the pial basement membrane. (jneurosci.org)
Interference RNA-mediated knockdown of GPR56 recapitulates the loss of adhesion seen in knock-outs, and reexpression of GPR56 rescues the adhesion defect in knock-out granule cells. (jneurosci.org)
