Abstract The functional Val158Met polymorphism (rs4680) located at the gene that codes for catechol‐ O ‐methyltransferase ( COMT ) has been extensively investigated in schizophrenia although current data are still controversial. Since activity is sexually dimorphic, we carried out two independent studies homogeneous samples of male and female Spanish schizophrenic patients. In males, found an association between homozygous Val genotype disorder, which resembled a recessive model P = 0.022;...

Little is known about the role of lipoprotein receptor-related protein-2 (LRP2)/megalin in central nervous system (CNS). Previous studies have indicated that megalin, an endocytic receptor binds multiple ligands, expressed ventricular ependymal cells, choroid plexus epithelium, and endothelial but absent from neurons adult brain. It likely structures where megalin has been detected it participates endocytosis transport amyloid β-peptide (Aβ) complex across vascular membranes, including...
