Title：Establishmentofamulti-epitoperecombinantAβvaccineandstudyonitsimmuneresponseeffect

Introduction：

Alzheimersdisease(AD)isachronic,neurodegenerativedisorderthataffectsmillionsofpeopleworldwide.OneofthepathologicalfeaturesofADistheaccumulationofamyloid-β(Aβ)peptidesinbraintissue.RecentstudiessuggestthatvaccinationagainstAβmaybeapotentialtherapyforAD.However,previousclinicaltrialsusingfull-lengthAβastheantigenhavenotshownsatisfactorytherapeuticbenefits.Toaddressthisissue,weproposetodevelopamulti-epitoperecombinantAβvaccinethattargetsmultipleAβepitopestoelicitamoreeffectiveimmuneresponse.

Objectives:

1.TocloneandexpressmultipleepitopesofAβasrecombinantfusionproteins

2.Topurifyandassembletherecombinantfusionproteinsintoamulti-epitopevaccine

3.Toevaluatetheimmunogenicityofthemulti-epitopevaccineinvitroandinvivo

Methods:

1.BioinformaticsanalysisofAβepitopestoselectcandidateepitopesforthevaccine

2.Codinggenesfortheselectedepitopeswillbesynthesizedandclonedintoexpressionvectors

3.Expressionandpurificationoftheepitope-fusionrecombinantproteins

4.Purificationandassemblyoftherecombinantproteinsintoamultimericvaccine

5.Immunizationofmicewiththemulti-epitopevaccine,measuringtheirantibodyresponseandTcellresponse

Expectedoutcomes:

Weanticipatethatthemulti-epitopeAβvaccinewillelicitastrongerimmuneresponsecomparedtofull-lengthAβvaccination.OurstudymayofferanewapproachfordevelopinganeffectivetherapeuticstrategyforAD.

Conclusion:

Theestablishmentofamulti-epitoperecombinantAβvaccineandtheevaluationofitsimmunogenicitywillprovideinsightintothedevelopmentofamoreefficaciousvaccineforAD.
