Figure Legend Snippet: In vivo AMD3100 administration increases NR2B protein levels in the rat cortex. ( a ) AMD3100 treatment decreases CXCR4 phosphorylation in brain slices of treated animals as detected through immunohistochemistry, using phospho-specific antibodies against ligand-activated CXCR4. Three animals per group were analyzed and no changes were observed in total levels of CXCR4.

Figure Legend Snippet: CXCL12 treatment reduces levels of NR2B protein and mRNA but does not alter other NMDA subunits.

Figure Legend Snippet: CXCL12 reduces global histone H3 acetylation in neurons, and histone deacetylase (HDAC) inhibitors prevent the effects of CXCL12 on the NR2B. ( a ) Global H3 acetylation levels were measured through a colorimetric acetylation assay as indicated in the ‘Materials and methods' section. Reduced levels of histone acetylation were found in CXCL12-treated (20 nM) neurons compared with control; this effect is blocked by cotreatment with TSA (100 nM) ( * P
