Myelin Basic Protein and Cardiac Sympathetic Neurodegeneration in Nonhuman Primates
Figure 4
A subset of sympathetic axons in myocardial nerve bundles are myelinated. Photomicrographs of immunofluorescent labeling of MBP, TH, and PGP9.5 in myocardial nerve bundles in the base (a) and apex (b) levels of a control animal. Scale = 50 μm. White arrows point to sympathetic axons (green TH-immunoreactivity (-ir) and red PGP9.5-ir; yellow color) that are myelinated (surrounded by pink MBP-ir). MBP, myelin basic protein; TH, tyrosine hydroxylase; PGP9.5, protein gene product 9.5.
