Tissue expression of CSF1R. (A) Relative CSF1R and GAPDH expression assessed by RT-PCR in postmortem brain RNA from normal control and AD individuals. (B) Expression of CSF1R transcripts and the house-keeping gene GAPDH in the EC and BA9 preassociation cortex (BA9) from patient H (c.2603T>G, p.L868R). RT-PCR for CSF1R exon 11 to 20, exon 11 to 19, exon 17 to 20, and exon 17 to 22 as indicated. Abbreviations: EC, entorhinal cortex; BA, Brodmann area; AD, Alzheimer’s disease; C, normal control; RT-PCR, Real Time PCR.
