Abstract

NMDA receptor (NMDAR) channels allow Ca(2+) influx only during correlated activation of both pre- and postsynaptic cells; a Mg(2+) block mechanism suppresses NMDAR activity when the postsynaptic cell is inactive. Although the importance of NMDARs in associative learning and long-term memory (LTM) formation has been demonstrated, the role of Mg(2+) block in these processes remains unclear. Using transgenic flies expressing NMDARs defective for Mg(2+) block, we found that Mg(2+) block mutants are defective for LTM formation but not associative learning. We demonstrate that LTM-dependent increases in expression of synaptic genes, including homer, staufen, and activin, are abolished in flies expressing Mg(2+) block defective NMDARs. Furthermore, we show that genetic and pharmacological reduction of Mg(2+) block significantly increases expression of a CREB repressor isoform. Our results suggest that Mg(2+) block of NMDARs functions to suppress basal expression of a CREB repressor, thus permitting CREB-dependent gene expression upon LTM induction.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • rs668387, rs2070045, rs11218343 and rs3781834 appear protective, whereas other variants such as rs143571823 aggravate AD pathogenesis.

    “For instance, rs668387, rs2070045, rs11218343 and rs3781834 appear to be protective [474, 482], whereas other variants of SORL1, such as rs143571823, aggravate AD pathogenesis [483].”
  • Reduced Mg2+ levels decrease Ca2+ influx mediated by NMDAR and damage-associated learning and long-term memory deficits in Drosophila.

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.
