Early stages of T cell development are thought to include a series of coordinated interactions between thymocytes and other cells of the thymus. A monoclonal antibody specific for mouse CD81 was identified that blocked the appearance of alpha beta but not gamma delta T cells in fetal organ cultures initiated with day 14.5 thymus lobes. In reaggregation(More)
The neurotrophic growth factor brain derived neurotrophic factor (BDNF) was linked to the risk of alcohol relapse in clinical studies. In this study we investigated alterations in the methylation of the BDNF gene during alcohol withdrawal (day 1, 7 and 14) in 99 male alcohol-dependent patients compared to age matched healthy males (n=33). In particular, we(More)
Neurotrophins (NTs) and their receptors play a key role in neurogenesis and survival. The TRK (tropomyosin-related kinase) receptor protein tyrosine kinases (TRKA, TRKB, TRKC) are high-affinity NT receptors that are expressed in a variety of human tissues. Their role in normal and malignant hematopoiesis is poorly understood. In a prospective study(More)
Major questions of neurological and psychiatric mechanisms involve the brain functions on a molecular level and cannot be easily addressed due to limitations in access to tissue samples. Post mortem studies are able to partly bridge the gap between brain tissue research retrieved from animal trials and the information derived from peripheral analysis (e.g.,(More)
Outbred rat lines such as Wistar rats are commonly used for models of depressive disorders. Such rats arise from random mating schedules. Hence, genetic drift occurs in outbred populations which could lead to genotypic and phenotypic heterogeneity between rats from different vendors. Additionally, vendor specific rearing conditions could contribute to(More)
Low prepulse inhibition (PPI) of startle is associated with reduced sensorimotor gating found in schizophrenia. In rats with breeding-induced low PPI neuregulin (NRG1) methylation was significantly decreased in brain regions associated with this phenotype and with schizophrenia, i.e., the medial prefrontal cortex, the nucleus accumbens, and the ventral(More)
Asymmetric di-methylarginine, an endogenous inhibitor of nitric oxide synthase, is increasingly recognized as vascular risk factor. Elevated ADMA levels have been described not only in 'typical' vascular diseases like congestive heart failure, artherosclerosis and diabetes but also for major depression and Alzheimer's disease. As homocysteine increases ADMA(More)
The expression pattern of important transduction molecules in nociceptive sensory neurons is likely to dictate pain sensitivity. While this notion is well established for increased pain sensitivities under conditions like inflammation and neuropathy, less is known as to which molecules are defining interindividual differences in pain sensitivity in healthy(More)
Common ethanol detection methods are not applicable to cell culture media and microdialysates due to interference with medium constituents including amino acids and pH indicators. We present a novel GC-MS method for the accurate and precise analysis of ethanol in cell cultures and microdialysates. The method is based on the carbonate-catalyzed extractive(More)
