Brain-derived neurotrophic factor (BDNF) is the most widely distributed neurotrophin in the central nervous system (CNS), and performs many biological functions such as neural survival, differentiation, and plasticity. Previous studies have suggested that variants in the BDNF gene increase the risk of schizophrenia. In this study, we genotyped one (GT)n(More)
Investigation of possible mechanisms to describe the hyporesponsiveness of pulmonary leukocytes has led to the study of pulmonary surfactant and its constituents as immune suppressive agents. Pulmonary surfactant is a phospholipid-protein mixture that reduces surface tension in the lung and prevents collapse of the alveoli. The most abundant protein in this(More)
Results of gene expression microarray and quantitative PCR studies have suggested abnormalities in the expression of myelin-related genes including myelin-associated glycoprotein (MAG) in schizophrenic patients. Research provides strong evidence for oligodendrocyte dysfunction in schizophrenics. In order to further assess the role of MAG in schizophrenia,(More)
The S100B gene locates in 21q22.3 and produces neurotrophin mainly in astrocytes of CNS which can act as an extensive marker of glial cell integrity. The synaptic destabilization hypothesis (GGF/SD) suggests that the functional deficiency of growth factors like S100B is involved in the etiology of schizophrenia and the S100B serum concentration is reported(More)
Recently, a second pathway for the generation of potential oxidants with the reactivity of the hydroxyl radical without the need for metal catalysis has been described. In response to various inflammatory stimuli, lung endothelial, alveolar, and airway epithelial cells, as well as activated alveolar macrophages, produce both nitric oxide (.NO) and(More)
The PIK3C3 gene has been implicated as a candidate gene for schizophrenia by functional evidence and genetic association studies. A series of previous studies have found susceptibility SNPs in promoter region. To further verify its susceptibility to schizophrenia in the Chinese population and the function of the polymorphisms, we performed a case control(More)
We investigated whether nitration of surfactant apoprotein (SP) A alters its ability to bind to mannose-containing saccharides on Pneumocystis carinii and its potential role in the mediation of P. carinii adherence to alveolar macrophages. Human SP-A was nitrated by incubation with tetranitromethane at pH 8.0 or synthetic peroxynitrite (ONOO-) at pH 7.4,(More)
We investigated the presence of Ca(2+)-activated Cl-channels in adult rat alveolar type II (ATII) using patch-clamp techniques. Only one active channel each, with a single channel conductance of 50 pS and an opening probability (Po) of 0.76 was found among 130 successful cell-attached and 5 inside-out patches. Addition of CPT-cAMP into the bath (500 microM)(More)
