The presence of naturally occurring anti-sperm antibodies (ASA) is a well-known cause of infertility in men and women, but the antigens for these antibodies are poorly characterized. We have previously shown that prostasomes adhere to sperm cells and that prostasomes are major targets for ASA associated with infertility. These autoantigens have not been characterized. We used 2-dimensional electrophoresis, immunoblotting, and mass-spectrometry to identify the prostasome antigens for these autoantibodies. By these techniques, we revealed that prolactin-inducible protein (PIP) and clusterin were dominant prostasome immunogens for sperm-agglutinating autoantibodies of 20 patients with immunological infertility. PIP was identified by 19 of 20 (95%) patient sera and clusterin by 17 of 20 (85%). In addition, 10 sporadically occurring prostasomal antigens were identified in this context, viz alcohol dehydrogenase [NADP+], annexin I, annexin III, BRCA1-associated ring domain protein 1, heat shock 27-kd protein, isocitrate dehydrogenase, lactoylglutathione lyase, NG,NG-dimethylarginine dimethylaminohydrolase 1, peroxiredoxin 2, and syntenin 1.

Central post-stroke pain (CPSP) is one of the complications of cerebral ischemia and neuropathic pain syndrome. At present, there are few studies of pain in regions such as the spinal cord or sciatic nerve in cerebral ischemic animal models. To identify proteomic changes in the spinal cord and sciatic nerve in global cerebral ischemic model mice, in the present study we performed an investigation using proteomic methods. In a comparison between the intensity of protein spots obtained from a sham and that from a bilateral carotid artery occulusion (BCAO) in spinal cord and sciatic nerve, the levels of 10 (spinal cord) and 7 (sciatic nerve) protein spots were altered. The protein levels in the spinal cord were significantly increased in N(G),N(G)-dimethylarginine dimethylaminohydrolase 1 (DDAH1), 6-phosphogluconolactonase isoform 1, and precursor apoprotein A-I and decreased in dihydropyrimidinase-related protein 2 (CRMP-2), enolase 1B, rab guanosine 5'-diphosphate (GDP) dissociation inhibitor beta, septin-2 isoform a, isocitrate dehydrogenase subunit alpha, cytosolic malate dehydrogenase, and adenosine triphosphate synthase. The protein levels in the sciatic nerve were significantly increased in a mimecan precursor, myosin light chain 1/3, and myosin regulatory light chain 2 (MLC2), and decreased in dihydropyrimidinase-related protein 3 (CRMP-4), protein disulfide-isomerase A3, 3-hydroxy-3-methylglutaryl-coenzyme A synthase 1, and B-type creatine kinase. In addition, CRMP-2 and CRMP-4 protein levels were decreased, and DDAH1 and MLC2 protein levels were increased on day 1 after BCAO using Western blotting. These results suggested that changes in these proteins may be involved in the regulation of CPSP.
