Fig 1. Cx43 and drebrin colocalization analysis in brain and cellular models.

(A) Rat brain transversal slice mosaic shown after multiple immunolabeling with antibodies anti-Cx43 (red), anti-drebrin (green), and anti-GFAP (blue) as astrocytes marker. White boxes localize the area enlarged in insets 1, 2, and 3 (six fold enlargement). Colocalization of drebrin and Cx43 (yellow) is especially noticeable around the blood vessels (inset 2) and in regions rich of astrocytes (insets 1 and 3). The different regions of the brain were labeled. Cultured astrocytes (B and C) and Vero cells (D and E) were immunolabeled with anti-Cx43 (red), anti-drebrin (green), and anti-actin (blue). White arrows indicate zones of colocalization of Cx43, drebrin and actin that were enlarged in the insets (white boxes, three fold enlargement).
