Brain‐derived Neurotrophic Factor is a Survival Factor for Cultured Rat Cerebellar Granule Neurons and Protects them Against Glutamate‐induced Neurotoxicity
Abstract
We have studied the effects of different neurotrophins on the survival and proliferation of rat cerebellar granule cells in culture. These neurons express trkB and trkC, the putative neuronal receptors for brain‐derived neurotrophic factor (BDNF) and neurotrophin‐3 (NT‐3) respectively. Binding studies using iodinated BDNF and NT‐3 demonstrated that both BDNF and NT‐3 bind to the cerebellar granule neurons with a similar affinity of ˜ 2x10‐9 M. The number of receptors per granule cell was surprisingly high, ∼30x10‐4 and 2x 10 5 for BDNF and NT‐3, respectively. Both NT‐3 and BDNF elevated c‐fos mRNA in the granule neurons, but only BDNF up‐regulated the mRNA encoding the low‐affinity neurotrophin receptor (p75). In contrast to NT‐3, BDNF acted as a survival factor for the granule neurons. BDNF also induced sprouting of the granule neurons and significantly protected them against neurotoxicity induced by high (1 mM) glutamate concentrations. Cultured granule neurons also expressed low levels of BDNF mRNA which were increased by kainic acid, a glutamate receptor agonist. Thus, BDNF, but not NT‐3, is a survival factor for cultured cerebellar granule neurons and activation of glutamate receptor(s) up‐regulates BDNF expression in these cells.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
