Brain derived neurotrophic factor (BDNF) is crucial for the formation of appropriate synaptic connections during development and for learning and memory in adults. Secretion of this neurotrophin is under activity-dependent control. Understanding which patterns of physiological activity regulate BDNF secretion is therefore an important step in the comprehension of its role. We have recently show...

A funder is incorrectly omitted from the Funding statement. The correct Funding statement is as follows: This work was supported by a Polish-German cooperation grant (S007/P-N/2007/01); National Science Center grant N N401 324739; EMBO Short-Term Fellowship to E. Z. (ASTF 211.00.2007); GA No 264173 (Bio-Imagine) and statutory funds for the Nencki Institute. The funders had no role in study desi...

The secretion of BDNF from neurons is under activity-dependent control: this is crucial for the formation of appropriate synaptic connections during development and for learning and memory in adults. New evidence shows that interaction between a motif in the tertiary structure of BDNF and the sorting receptor carboxypeptidase E directs this neurotrophin to the regulated secretory pathway.

Several findings have suggested that the neurotrophin BDNF could contribute to clinical efficacy of antidepressant treatments. The purpose of this study was to analyse if ECT operates a modulation of serum BDNF levels in a sample of drug resistant depressed patients. The results obtained show significantly higher serum levels of BDNF following ECT. More specifically, while no change occurred in...

The neurotrophin gene family comprises four structurally related basic proteins, NGF, BDNF, NT-3 and NT-4/5. Despite high structural homology, these neurotrophins operate via different high-affinity membrane receptors, differ in target specificity, patterns of spatial and temporal distribution and responses to injury of the neuronal tissue. Based on the recent data, some aspects of BDNF and NT-...

Disturbed neural development has been postulated as a crucial factor in the pathophysiology of schizophrenic psychoses. The neurobiochemical basis for such changes of cytoarchitecture and changed neural plasticity could involve an alteration in the regulation of neurotrophic factors. In order to test this hypothesis, BDNF and NT-3 levels in post-mortem brain tissue from schizophrenic patients w...

Neurotrophins are important proteins that regulate survival, development and function of neurons. They are produced by a variety of cells and exert their effects upon binding to specific tyrosine kinase receptors. The first neurotrophin to be identified was Nerve Growth Factor (NGF). From the pioneer studies performed by Rita-Levi Montalcini, awarded with the Nobel Prize, other neurotrophins ha...
