Key Event Components

The KE, as defined by a set structured ontology terms consisting of a biological process, object, and action with each term originating from one of 14 biological ontologies (Ives, et al., 2017; https://aopwiki.org/info_pages/2/info_linked_pages/7#List). Biological process describes dynamics of the underlying biological system (e.g., receptor signalling).Biological process describes dynamics of the underlying biological system (e.g., receptor signaling).  The biological object is the subject of the perturbation (e.g., a specific biological receptor that is activated or inhibited). Action represents the direction of perturbation of this system (generally increased or decreased; e.g., ‘decreased’ in the case of a receptor that is inhibited to indicate a decrease in the signaling by that receptor).  Note that when editing Event Components, clicking an existing Event Component from the Suggestions menu will autopopulate these fields, along with their source ID and description.  To clear any fields before submitting the event component, use the 'Clear process,' 'Clear object,' or 'Clear action' buttons.  If a desired term does not exist, a new term request may be made via Term Requests.  Event components may not be edited; to edit an event component, remove the existing event component and create a new one using the terms that you wish to add.  Further information on Event Components and Biological Context may be viewed on the attached pdf.

Glutamate induces the translocation of drebrin from dendritic spines to dendritic shafts, as reported in mature cultured rodent neurons and human iPS-derived neurons (Sekino et al. 2006; Mizui et al.2014; Lin et al. 2023). This "drebrin exodus" is a physiological process occurring at the initiation of synaptic plasticity, observed immediately after excitatory postsynapses receive electrical or chemical stimulation that induces long-term potentiation (LTP) or long-term depression (LTD) .

NMDA-induced excitotoxicity leads to the degradation of drebrin in mature cultured neurons from rodent hippocampus and cortex. This process is triggered by calcium influx and mediated by calpain activity.

Drebrin is an evolutionarily conserved actin-binding protein localized in dendritic spines. Overexpression of drebrin A in neurons enlarges dendritic spines and reduces spine motility, whereas down-regulation of drebrin A decreases the density and width of dendritic spines and inhibits the synaptic clustering of NMDA receptors (NMDARs).

Drebrin stabilizes actin filaments and plays a pivotal role in dendritic spine morphogenesis (Hayashi and Shirao, 1999; Takahashi et al., 2003; Takahashi et al., 2006).

During the initial stages of synaptic plasticity (either LTP or LTD), Ca²⁺ influx through NMDA receptors triggers the translocation of drebrin from dendritic spines (Sekino et al., 2006).

Moreover, prolonged NMDA-induced excitotoxicity results in calpain-mediated degradation of drebrin both in vitro and in vivo.

How It Is Measured or Detected

A description of the type(s) of measurements that can be employed to evaluate the KE and the relative level of scientific confidence in those measurements.These can range from citation of specific validated test guidelines, citation of specific methods published in the peer reviewed literature, or outlines of a general protocol or approach (e.g., a protein may be measured by ELISA). Do not provide detailed protocols. More help

Loss of drebrin from dendritic spines can be detected by immunocytochemistry, ELISA or or Western blotting  in cultured human and rodent neurons and brain tissues (Counts et al., 2006; Ishizuka et al., 2014).

The twenty-one-day primary cultured neurons were prepared using frozen stock of dissociated hippocampal neurons (Koganezawa et al, 2023; Hanamura et al 2019). In brief, cells were cultured in multi well microplates with defined medium. Using cryopreservednhippocampal neurons reduces animal use.

For enzyme-linked immunoassay, after the incubation of chemicals the extracts of neurons were quantified using ELISA kit for drebrin (ALzMEd, Inc.),

For immunocytochemistry, the cultured neurons were incubated with chemicals for 1 hour. After fixation, cultured neurons were immunostained with anti-drebrin and anti-MAP2 antibodies. The cluster density of drebrin along the dendrites was automatically quantified using high content analysis instruments (Hanamura et al, 2019, Mitsuoka et al, 2019).
