Background.
Calreticulin (CRT) can bind to Fas ligand (FasL) and inhibit Fas/FasL-mediated apoptosis of Jurkat T cells.
However, its effect on neuronal cell apoptosis has not been investigated.
Purpose.
We aimed to evaluate the neuroprotective effect of CRT following ischemia-reperfusion injury (IRI).
Methods.
Mice underwent middle cerebral artery occlusion (MCAO) and SH-SY5Y cells subjected to oxygen glucose deprivation (OGD) were used as models for IRI.
The CRT protein level was detected by Western blotting, and mRNA expression of CRT, caspase-3, and caspase-8 was measured by real-time PCR.
Immunofluorescence was used to assess the localization of CRT and FasL.
The interaction of CRT with FasL was verified by coimmunoprecipitation.
SH-SY5Y cell viability was determined by MTT assay, and cell apoptosis was assessed by flow cytometry.
The measurement of caspase-8 and caspase-3 activity was carried out using caspase activity assay kits.
Results.
After IRI, CRT was upregulated on the neuron surface and bound to FasL, leading to increased viability of OGD-exposed SH-SY5Y cells and decreased activity of caspase-8 and caspase-3.
Conclusions.
This study for the first time revealed that increased CRT inhibited Fas/FasL-mediated neuronal cell apoptosis during the early stage of ischemic stroke, suggesting it to be a potential protector activated soon after IRI.
