Claims (12)

1. Konformationssensitivt antistof, der kan tilvejebringes ved hjælp af et anti-genkonstrukt omfattende et antigenpeptid, som har aminosyresekvensen β-amyloid udvalgt fra gruppen bestående af SEQ ID NO: 1, SEQ ID NO: 2, SEQ ID NO: 3, SEQ ID NO: 4 and SEQ ID NO: 5, eller et aktivt fragment deraf, hvor antigenpeptidet eller det aktive fragment deraf er modificeret til at have en polyethylenglycol kovalent tilknyttet, en ved hver terminus, og er rekonstitueret i en liposom, hvilket antistof har bindingsspecifitet for antigenpeptidet og (a) udviser en konformationsfølsomhed og en affinitet for antigenet, hvilken er forbedret sammenlignet med et antistof frembragt af det palmitoylerede antigenpeptid; og (b) forårsager en overgang fra β-blad til a-helix af amyloidpeptid.
2. Antistof ifølge krav 1, hvor antistoffet er af isotypen lgG1.
3. Antistof ifølge krav 1, hvilket efter en inkubation med amyloidfibre fører til fibre med en størrelse på < 800 nm i 40-60 % af alle forekommende fibre.
4. Antistof ifølge krav 1 frembragt af et antigenkonstrukt omfattende et antigenpeptid med aminosyresekvensen ifølge SEQ ID NO: 1 modificeret til at indeholde en lysin kovalent knyttet ved hver terminus af amyloidsekvensen FRHDSGY og en polyethylenglycol (PEG) kovalent bundet til lysin ved en ende og dioleyl-phosphatidylcholinethanolamin ved den anden ende af PEG-molekylet, hvilket antistof (a) effektivt opløser Αβι_4ο- og Αβι-42-fibre; og (b) beskytter in vitro PC12-celler mod apoptose og metabolsk inhibition forårsaget af Αβι.40- og Αβι-42-fibre.
5. Antistof ifølge et af de foregående krav, hvor antistoffet er et polyklonalt antistof eller et monoklonalt antistof.
6. Antistof ifølge krav 4, hvilket efter indgivelse til en patient, som er et dyr eller et menneske, fører til væsentlige niveauer af genetablering af hukommelsen og vækkelse af nysgerrigheden uden at forårsage blødning i hjernen hos den immuniserede patient, som er et dyr eller et menneske.
7. Antistof ifølge krav 1, hvilket binder til opløselige Αβι-40-oligomerer.
8. Anvendelse af en epitop udvalgt fra gruppen bestående af SEQ ID NO: 2, SEQ ID NO: 3 og SEQ ID NO: 4, eller et aktivt fragment deraf, indlejret i et antigenkonstrukt omfattende et antigenpeptid eller et aktivt fragment deraf, som er modificeret til at have en polyethylenglycol kovalent tilknyttet, en ved hver terminus, og er rekonstitueret i en liposom til generering af et antistof ifølge et af kravene 1-7.
9. Antistof ifølge et af kravene 1-7 til passiv immunisering af individer mod neurologiske sygdomme og forstyrrelser.
10. Antistof ifølge krav 9, hvor sygdommen eller lidelsen er Alzheimers sygdom.
11. Fremgangsmåde til fremstilling af et konformationssensitivt antistof til passiv immunisering af individer mod neurologiske sygdomme og forstyrrelser, hvilken fremgangsmåde omfatter at rekonstituere et antigenkonstrukt i liposomer, hvor antigenkonstruktet omfatter et peptid med aminosyresekven-sen β-amyloid eller et aktivt fragment deraf, udvalgt fra gruppen bestående af SEQ ID NO: 1, SEQ ID NO: 2, SEQ ID NO: 3, SEQ ID NO: 4 og SEQ ID NO: 5, eller et aktivt fragment deraf, hvor antigenpeptidet eller det aktive fragment deraf er modificeret til at have en polyethylenglycol kovalent tilknyttet, en ved hver terminus, og rejser et antistof, som er rettet mod antigenkonstruktet.
12. Fremgangsmåde ifølge krav 11, hvor den neurologiske sygdom er Alzheimers sygdom.
