Dose-dependent protective effect of connexin43 mimetic peptide against neurodegeneration in an ex vivo model of epileptiform lesion

JJ Yoon, CR Green, SJ O'Carroll, LFB Nicholson - Epilepsy research, 2010 - Elsevier
Epileptic seizures typically result in delayed neuronal loss secondary to the initial damage
and an up-regulation in connexin43 (Cx43). This study investigated the role of Cx43 gap …

Connexin36 Gap Junction Blockade Is Ineffective at Reducing Seizure‐Like Event Activity in Neocortical Mouse Slices

LJ Voss, N Mutsaerts, JW Sleigh - Epilepsy Research and …, 2010 - Wiley Online Library
Despite much research, there remains controversy over the role of gap junctions in seizure

Curious and contradictory roles of glial connexins and pannexins in epilepsy

PL Carlen - Brain research, 2012 - Elsevier
Glia play an under-recognized role in epilepsy. This review examines the involvement of
glial connexins (Cxs) and pannexins (Panxs), proteins which form gap junctions and …

Connexin 43 mRNA expression in two experimental models of epilepsy

K Elisevich, SA Rempel, B Smith, N Allar - Molecular and chemical …, 1997 - Springer
The expression of mRNA for connexin 43, a gap junction protein putatively found in
astrocytes, is studied in two experimental models of epilepsy: the electrically kindled rat and …

Upregulation in astrocytic connexin 43 gap junction levels may exacerbate generalized seizures in mesial temporal lobe epilepsy

CG Fonseca, CR Green, LFB Nicholson - Brain research, 2002 - Elsevier
Following brain injury, and during the process of neurodegeneration, a reactive astrocytic
proliferation occurs. This is accompanied by an increase in the synthesis of neuropeptides …
