Her beskriver vi en kombineret tilgang, for at studere cellulære og molekylære aspekter af amylopathies hjælp C. elegans. Fordelene ved denne fremgangsmåde omfatter: 1). Lave omkostninger C.elegans opretholdes i normal petriskål podet med bakterier, ved stuetemperatur. 2) Stærke genetik. Transgene dyr kan opnås i nogle måneder, og en bred vifte af promotorsekvenser er tilgængelig til at drive ekspression af det ønskede gen i bestemte neuroner. 3) Enkle, velkarakteriseret, nervesystem. C. ...

Amyloid p (Ap) er et peptid på 36-43 aminosyrer, der dannes efter sekventiel spaltning af amyloidprecursorprotein (APP) ved β og γ sekretaser 1.. Den γ sekretase behandler den C-terminale ende af Ap-peptidet og er ansvarlig for dens variable længder 5. De mest almindelige former for Ap er Ap 40 og Ap 42, idet sidstnævnte mere almindeligt i forbindelse med patologiske tilstande, såsom AD 5. Ved høje koncentrationer Ap danner β-sheets, som aggregerer at danne amyloid fibriller 6.. Fibriller indskud er den vigtigste bestanddel af senile plaques omkringliggende neuroner. Både plaques og diffunderbare, ikke-plak Ap oligomerer, menes at udgøre de underliggende patogene former for Ap. Laboratorieundersøgelse af neuronale amylopathies kompliceres af den kendsgerning, at disse betingelser fremskridt med tiden. Derfor er det important til at udvikle genetisk medgørlig dyremodeller-supplement til mus-med kort levetid. Disse modeller kan anvendes til at belyse specifikke aspekter af amylopathies-typisk cellulær og molekylær-og i kraft af deres enkelhed, hjælper til at fange essensen af ​​problemet. Ormen Caenorhabditis elegans falls er denne kategori. Den har en kort levetid, ~ 20 dage og derudover grundlæggende cellulære processer, herunder regulering af genekspression, protein menneskehandel, neuronal tilslutningsmuligheder, synaptogenesis, cellesignalering og død ligner pattedyr 7.. Unikke funktioner i ormen omfatter kraftige genetik og mangel på et fartøj system, som gør det muligt at studere nerveskader uafhængigt af vaskulær skade. På den anden side begrænser manglen på en hjerne brugen af C. elegans til at studere mange aspekter af neurodegeneration. Derudover kan reproduktion og identifikation af anatomiske fordelinger af læsioner ikke udføres i denne organisme. Anden begrænsningtioner omfatter det er vanskeligt at vurdere både forskelle i genekspression profiler og nedskrivninger af komplekse adfærd og memory funktion. Her beskriver vi metoder til at generere C. elegans modeller amylopathies.

a caenorhabditis elegans model system for amylopathy study

Amylopathy er et begreb, der beskriver unormal syntese og akkumulering af amyloid beta (Ap) i væv med tiden. Ap er kendetegnende for Alzheimers sygdom (AD) og findes i Lewy body demens, inklusion krop myositis og cerebral amyloidangiopati 1-4. Amylopathies gradvist udvikle sig med tiden. Af denne grund simple organismer med kort levetid kan bidrage til at belyse molekylære aspekter af disse betingelser. Her beskriver vi forsøgsprotokoller at studere Ap-medieret neurodegeneration ved hjælp af ormen Caenorhabditis elegans. Således har vi konstruere transgene orme ved at indsprøjte DNA kodende human Ap 42 ind i de syncytial gonaderne af voksne hermafroditter. Transformant linjer stabiliseres ved en mutagenese-induceret integration. Nematoder er alder synkroniseres ved at indsamle og såning deres æg. Funktionen af neuroner udtrykker Ap 42 testes i opportunt adfærdsmæssige assays (kemotaxi-assayr). Primære neuronale kulturer opnået fra embryoner anvendes som et supplement adfærdsmæssige data og teste de neurobeskyttende virkninger af anti-apoptotiske forbindelser.

Med vores protokoller vi studerer virkningerne af human Ap 42 oligomer på neuronal funktion 8.. Et fragment koder for human Ap 42 og den kunstige signalpeptidkodende sekvens af Fire vektor pPD50.52 blev amplificeret fra konstrukt PCL12 9 anvendelse af primere, som indførte en Smal 1 restriktionsendonukleasested ved enderne. Fragmentet blev derefter indsat i en konstruktion indeholdende en 2.481 bp FLP-6 promotorsekvens i pPD95.75 Fire vektor mellem det unikke Sma 1-...
