isaga EAAT2 glutamate transporter, wuxuu xisaabiyaa> 90% qaadashada glutamate ee hippocampal.Inkasta oo EAAT2 inta badan lagu muujiyo astrocytes, ~ 10% ee EAAT2 molecules waxaa laga helaa terminaalka axon.In kasta oo heerka hoose ee muujinta EAAT2 ee marinnada glutamatergic, marka jeexjeexyada hippocampal lagu daro feejignaanta hoose ee d-aspartate ( substrate EAAT2), terminaalka axon waxay u ururiyaan d-aspartate sida ugu dhakhsaha badan sida astroglia.Tani waxay tusinaysaa ismaandhaaf aan la garanayn oo u dhexeeya qaybinta borotiinka EAAT2 iyo dhaqdhaqaaqa gaadiidka dhexdhexaadka ah ee EAAT2.Hal mala awaal ayaa ah in (1) heteroexchange of substrate gudaha leh substrate dibadda ayaa aad uga dhaqso badan qaadashada saafiga ah iyo (2) terminalku waxay jecel yihiin heteroexchange sababtoo ah heerarka sare ee glutamate gudaha.Si kastaba ha ahaatee, hadda lama garanayo in heteroexchange iyo kor u qaadista ay leeyihiin heerar isku mid ah ama kala duwan.Si arrintan wax looga qabto, waxaan isticmaalnay nidaam dib loo habeeyay si aan is barbar dhigno heerarka isbarbardhigga ee labada habraac ee jiirka iyo jiirka.Qaadashada saafiga ah waxay dareen u ahayd isbeddellada awoodda xuubka waxaana kiciyay anions dibadda ka bixi kara iyadoo lagu heshiiyey jiritaanka anion conduction aan la wada socon.Isticmaalka kan dambe, waxaan sidoo kale muujineynaa in heerka heteroexchange uu sidoo kale ku xiran yahay awoodda xuubka.Intaa waxaa dheer, xogtayadu waxay si dheeraad ah u soo jeedinaysaa joogitaanka soodhiyamka ee EAAT2.Marka lagu daro natiijooyinka cusub ee qaabkeenii hore ee qaadashada glutamate ee EAAT2, waxaan saadaalineynaa in dareenka korantada ee sarrifka ay sababto ku-tiirsanaanta seddexaad ee Na (+) ku xiran.Dheeraad ah, labadaba tijaabooyinkayaga iyo jilitaannadayadu waxay soo jeedinayaan in heerarka qaraabada ee qaadashada saafiga ah iyo heteroexchange ay la mid yihiin EAAT2.
