Figure 4From: Role of spinal cord alpha-amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid receptors in complete Freund's adjuvant-induced inflammatory painThe relative levels of GluR2 (A and B) and GluR1 (C and D) in the crude cytosolic (A and C) and plasma membrane fractions (B and D) from the ipsilateral L 4–5 dorsal horn at 2 and 24 h following saline or CFA injection. Naïve rats (n = 4–8) were used as a control group. Data are presented as mean ± SEM. n = 4–8 rats/treatment. * p < 0.05, ** p < 0.01 vs the corresponding naïve group. E: The specificity of the fractionation procedure. Top: representative Western blots showing the expression of N-cadherin, PSD-95, and β-actin in total soluble fraction, plasma membrane fraction, and cytosolic fraction from L4–5 dorsal horns of naïve rats (n = 3). Bottom: statistical summary of the densitometric analysis expressed relative to the corresponding protein levels in the total soluble fraction.Back to article page
