Fig. 3. Glutamate-induced translocation of cPLA2
to the somatic and dendritic Golgi compartments. (A) A whole Purkinje cell co-expressing RFP-cPLA2
and GFP-GalT (a marker of the Golgi complex). Scale bar: 20 µm. Boxed areas are magnified in B. (B) The target sites of RFP-cPLA2
in response to 30 µM glutamate identified by subtraction analysis (left, the fluorescence image after glutamate addition was subtracted by the image before addition) colocalized with the Golgi marker GFP-GalT (middle) in the dendrites (upper panels) and soma (lower panels). Colocalization is apparent as a yellow in the merged image (right). Scale bars: 5 µm.
