positive-negative: subcellular expression differences Explanation: Protein has been detected in dendrites, but not soma.

"Fig. 8. Distribution of the GABA A receptor subunit immunoreactivities (a1-a6, b1-b3, c1, c2 and d) in the dorsal hippocampus (coronal sections of
the mouse brain approximately Bregma 1.82 mm, according to Franklin and Paxinos, 2007). Immunohistochemical labeling was predominantly
found in the respective dendritic fields, the strata oriens (so) and radiatum (sr) of CA1 to CA3 and in the molecular layer (ml) of the dentate gyrus.
Note the faint labeling of the a3-subunit restricted to the CA1 region. A strong expression of a2- and a5-subunits occurred throughout the
hippocampus proper with highest intensity in the CA3 area. Note the co-distribution of a4- and d-subunit protein in the dentate gyrus, but not in the
CA1-CA3 region."
