 Differen(al  expression  of  genes  in  the  CA2  area  of  hippocampus  of  mouse  brain  

 

 Nicholas  Mitsios                      Department  of  Neuroscience,  Karolinska  Ins(tute,  Stockholm,  Sweden  

 

Looking  for  genes  highly  enriched  in  CA2  area  that  could  poten8ally  contribute  to  the  unique  CA2  characteris8cs  (lack  of  plas8city  and  resistance  to  neuronal  injury)  using  “Fine  Structure  Search”,  “Differen/al  Search”  and  “AGEA”  

Amigo2  and  Rgs14  show  selec8ve  enrichment  in  adult  mouse  CA2  

 Unlike  Amigo2,  Rgs14  is  highly  expressed  in  the  adult  human  CA2  

DG   CA1   CA2  

0  months  CA2  

 Rgs14  highly  expressed  in  the  CA2  from  developing  macaque  brain  

•  RGS14,  known  to  suppress  object  recogni8on  memory  and  synap8c  plas8city  in  CA2,  is  highly  enriched  in  CA2  in  adult  mouse,  human  and  non-­‐human  primate  

•  RGS14  inhibi8on  may  serve  as  aLrac8ve  therapeu8c  target  for  future  cogni8ve  enhancers  with  possibly  direct  effect  for  human
