Rab22B is expressed in the CNS astroglia lineage and plays a role in epidermal growth factor receptor trafficking in A431 cells.

29 Nov 2009 The expression profile and functions of the brain-enriched Rab22B/Rab31 small GTPase had remained uncharacterized. Using specific antibodies against Rab22B, we found the protein to be exceptionally enriched in nestin and RC2-positive radial glia of ... Read more...

Expression and role of CXCL10 during the encephalitic stage of experimental and clinical African trypanosomiasis.

13 Nov 2009 BACKGROUND: Human African trypanosomiasis, caused by Trypanosoma brucei, involves an early hemolymphatic stage followed by a late encephalitic stage. METHODS: We studied the expression of chemokines with use of microarray and enzyme-linked ... Read more...

Localization of zip1 and zip4 mRNA in the adult rat brain.

30 Oct 2009 The localization of two members of the Slc39a (zip1 and zip4) family of zinc transporters was examined in the brains of adult mice. Zip1 was highly enriched in brain regions with high densities of neuronal cell bodies, including the hippocampus, ... Read more...

Technical information about 'Astrocytes'

Definition: A class of large neuroglial (macroglial) cells in the central nervous system - the largest and most numerous neuroglial cells in the brain and spinal cord. Astrocytes (from "star" cells) are irregularly shaped with many long processes, including those with "end feet" which form the glial (limiting) membrane and directly and indirectly contribute to the BLOOD-BRAIN BARRIER. They regulate the extracellular ionic and chemical environment, and "reactive astrocytes" (along with MICROGLIA) respond to injury.
