Test main material:Sprague-Dawley (SD) rat(Male and each 20 of female), body weight 200g 250g, purchased from Jiangsu Province's Experimental Animal Center.1. stereotaxic technique is used, by osmotic pump (osmotic minipump: Alzet 2002;Alze, CA) connection implantation catheter(Cannula), and be fixed on one side telocoele (0.3mm, right side lmm, deep 2.5mm after bregma).By Α β( 1_ 42) continuous 2 weeks(100pM/day) it is fed into telocoele.By observing Α β deposition, spatial memory function and Cholinergic, to verify whether AD models succeed.
Experimental implementation: Αβ( 1_ 42) irrigate after proceed by within the 2nd day continuous 14 days ABG-001 (0.5-1.0mg/kg) intraperitoneal injection.In Α β α -42 )Carry out water maze test within the 7th day after perfusion, check spatial memory function.The movement locus of rat is recorded, calculating is gone up on the stage incubation period.In Α βα_42)15 days after perfusion, fixed brain tissue is irrigated through left ventricle with 4% paraformaldehyde. After FFPE, hippocampus serial section is done.After 1% Toluidine blue staining, the density of measurement hippocampus CA1 area survival cones (pyramidal cell layer per mm length in granular cell number).
Experimental result Fig. 9: Αβα_42)Perfusion causes about 60% hippocampus CA1 area neuronal death to be lost, and causes escape latency to extend, and points out the reduction of spatial cognition function.ABG-001 treatments can significantly reduce Α βα_42)Dementia rats hippocampal neurons are dead, improve the Spatial memory function of Α β rats.
ABG-001 treatments can improve the brain endogenous nerve regneration obstacle of Alzheimer disease (AD)
The NSC of Adult Mammals hippocampal dentate can be divided into nerve cell referred to as nerve to occur.The nerve to occur of adult is considered to replace and repaired due to the neuron loss that natural aging or lesion are caused, and the 26S Proteasome Structure and Function of brain is safeguarded to greatest extent.Alzheimer disease (Alzheimer's disease, AD) is a kind of nervous system degenerative disease being characterized with progressive cognition dysfunction.Whether newborn neuron can substitute the neuron of lesion, improve AD cognition dysfunction and turned into the novel targets that AD is studied.Research finds that the neuronotropic differentiation ratio of precursor of AD cerebral hippocampals is significantly reduced, and the survival rate of synkaingenesis neuron is significantly reduced, and the enation of newborn neuron is abnormal.These researchs have confirmed that the nerve regeneration of AD brains is by serious infringement, and it is probably one of important pathomechanism of AD cognitive functions progressive decline to point out nerve regneration obstacle.
Test main material:APP/PS1 transgenosis AD mouse(10 monthly age male and female mouse)(It is purchased from Nanjing University's zootype center).Experimental implementation:With BrdU (5- bromodeoxyuridine nucleosides)The cell of m period is marked, ABG-001 administrations are carried out within continuous 14 days after B U injections(0.5mg/kg/ days).Then 28 days methods with SABC detect that the BrdU in hippocampus DG areas is positive after BrdU first administrations respectively(BrdU+) cell.Pass through neuronal specificity nucleoprotein() and Deiter's cells NeuN(GFAP immunostaining), influences of the observation ABG-001 to newborn Neural Differentiation.Doublecortin (DCX) in the growth course of central nervous system neural precursor transition process particular expression, DCX as neuronal precursor mark can for study neuronal precursor propagation and migration.The growth of newborn Neuronal processes can be observed by being dyed by DCX.Mouse was put to death in the 2nd day after last dose, hippocampus is taken out and determines acetylcholinesterase(AChE it is) active.
