ABSTRACT
Objective To investigate the expression changes of astrocytic syntrophin in hippocampus from human mesial temporal lobe epilepsy (MTLE). Methods From April, 2015 to July, 2016, 17 cases of hippocampus, collected from temporal lobectomy, were divided into MTLE group (n=13) and non-MTLE group (n=4) according to hematoxylin and eosin staining, glial fibrillary acidic protein and neuronal nu-clei immunohistochemical staining. Immunofluorescence double labeling and immunofluorescence histochemistry were used to observe the expression of syntrophin. Results The proliferation of astrocytes increased and neurons reduced in the hippocampus of MTLE group. Syntro-phin was found in the membrane and foot processes of astrocyte, that was enriched along perivascular astrocyte end-feet domain in non-MTLE group, but lost in MTLE group. While the whole expression of syntrophin was more in MTLE group than in non-MTLE group (t=5.421, P<0.001). Conclusion The distribution of syntrophin in hippocampus astrocytes may be related to the development of MTLE.
