Quantification of Iba-1, CX3CL1, and CX3CR1 protein expression in MSA. (A) Representative Western immunoblots in control [C] and MSA [M] frontal cortex. (B) No significant alteration was detected in the expression of Iba-1 in MSA compared with control. CX3CL1 was detected at the predicted molecular weight of ∼100 kDa (A), which showed a trend toward upregulation without significance (C). The lower molecular weight band representing the soluble form of the protein was detected at 60 kDa (A) and was significantly decreased in MSA when normalized to βIII-tubulin (C, p = 0.03). CX3CR1 was detected at the predicted molecular weight of 47 kDa (A) and showed a highly significant increase in expression in MSA brain compared with control when normalized to Iba-1, determined by Student t test of MSA compared with control (C, p = 0.0002).
