Tilmaamaha Alaabta

Muuqashada budo cad

 

Sigma reseptor 1 (σR1) waa borotiinka transmembrane non-opioid kaas oo u dhaqmi kara sida chaperone molecular ee xuubka endoplasmic reticulum-mitochondrial.Ligands ee σR1, sida (+) -pentazocine [(+) -PTZ], waxay siisaa difaaca neerfaha isha ee calaamadsan gudaha vivo iyo in vitro.Dhawaan waxaan falanqeynay nooca xuubka isha ee jiirarka oo ka maqan σR1 (σR1 KO) waxaanan aragnay qaab-dhismeedka indhaha ee caadiga ah iyo shaqada jiirarka da'da yar (5-30 toddobaad) laakiin waxay yareeyeen jawaabaha scotopic threshold jawaabaha (nSTRs), unugyada ganglion ee retinal (RGC) luminta, iyo carqaladeynta Dareemaha indhaha ee axon oo la jaan qaadaya cilladda isha ee gudaha 1 sano.Xogtaasi waxay noo horseeday inaan tijaabino mala-awaalka ah in σR1 laga yaabo inay muhiim u tahay ka hortagga diiqada daba-dheeraada ee isha;Si loo go'aamiyo in σR1 looga baahan yahay (+) -PTZ saamaynta neuroprotective, RGC-yada aasaasiga ah ee ka go'doonsan nooca duurjoogta ah (WT) iyo σR1 KO jiirarka ayaa la kulmay xanthine-xanthine oxidase (10 µM: 2 mU / ml) si loo kiciyo cadaadiska oksaydhka ee joogitaanka ama maqnaanshaha (+) -PTZ.Dhimashada unugga waxaa lagu qiimeeyay terminal deoxynucleotidyl transferase dUTP calaamadaynta dhamaadka nick (TUNEL).Si loo qiimeeyo saameynta diiqada daba dheeraatay ee shaqada RGC, sonkorowga waxaa lagu soo bandhigay 3-usbuuc C57BL/6 (WT) iyo σR1 KO jiirarka, iyadoo la adeegsanayo streptozotocin si ay u soo saarto afar kooxood: WT nondiabetic (WT non-DB), WT diabetes (WT-DB) ), σR1 KO non-DB, iyo σR1 KO-DB.Ka dib 12 toddobaad oo sonkorowga ah, markii jiirarka ay ahaayeen 15-usbuuc, cadaadiska intraocular (IOP) ayaa la duubay, baarista elektiroonigga ah ayaa la sameeyay (oo ay ku jiraan ogaanshaha nSTRs), tirada RGC-yada waxaa lagu tiriyaa qaybaha histological retinal. Daraasadaha In vitro ayaa muujiyay in (+)-PTZ kama hortegi karto dhimasha oksaydhative-ka ay keentay dhimashada RGC-yada laga soo goostay jiirarka σR1 KO laakiin waxay siisay difaac adag oo ka dhan ah dhimashada RGC-yada laga soo goostay jiirarka WT.Daraasadaha diiqada daba-dheeraada ee uu keeno sonkorowga, IOP-ga lagu qiyaasay afarta kooxood ee jiirka ayaa ku dhex jiray heerka caadiga ah;si kastaba ha ahaatee, waxaa jiray koror weyn oo ku yimid IOP ee jiirarka σR1 KO-DB (16 ± 0.5 mmH g) marka loo eego kooxaha kale ee la tijaabiyay (σR1 KO non-DB, WT non-DB, WT-DB: ~ 12 ± 0.6 mmHg ).Marka laga hadlayo tijaabinta korantada fiisigiska, nSTR-yada σR1 KO jiirarka aan DB ahayn waxay la mid yihiin jiirarka WT ee aan DB ahayn toddobaadyada 15;si kastaba ha ahaatee, waxay aad uga hooseeyaan jiirarka σR1 KO-DB (5 ± 1 µV) marka loo eego kooxaha kale, oo ay ku jiraan, gaar ahaan, σR1 KO-nonDB (12 ± 2 µV).Sida la filayo, tirada RGCs ee jiirarka σR1 KO non-DB waxay la mid ahaayeen jiirarka WT ee aan DB ahayn toddobaadyadii 15, laakiin diiqada daba dheeraatay ee sonkorowga waxaa jiray RGC-yada retina ee jiirka σR1 KO-DB. Tani waa warbixintii ugu horreysay. muujinaya si aan leexleexad lahayn in saamaynta neuroprotective ee (+) -PTZ ay u baahan tahay σR1.σR1 KO jiirarka ayaa muujinaya qaab dhismeedka isha ee caadiga ah iyo shaqada da'da yar;si kastaba ha ahaatee, marka ay la kulmaan walaaca dabadheeraad ah ee sonkorowga, waxaa jira dardargelinta cilladaha shaqeynta retinal ee σR1 KO jiirarka sida cilladda unugyada ganglion waxaa lagu arkay da' aad uga horraysa kuwa aan sonkorowga ahayn σR1 KO jiirarka.Xogtu waxay taageertaa mala-awaalka ah in σR1 ay door muhiim ah ka ciyaarto modu lating stress stress waxaana laga yaabaa inay bartilmaameed muhiim ah u tahay cudurka retina.
