Description:TLR3,Human,mAbTLR3.7,functionalstudyantibody,lowendotoxin
ThemonoclonalantibodyTLR3.7recognizesthe116kDahumanToll-likereceptor3(TLR3,CD283).Toll-likereceptors(TLRs)arehighlyconservedfromDrosophilatohumansandsharestructuralandfunctionalsimilarities.TLRsconstituteofafamilyofpatternrecognitionreceptors(PRRs)thatmediatecellularresponsestoalargevarietyofpathogens(viruses,bacteria,andparasites)byspecificrecognitionofso-called‘pathogen-associatedmolecularpatterns’.ActivationofTLRs,afamilyofatleast11differentmembersthatfunctioneitherashomo-orheterodimers,leadstoactivationofNFκBDependentandIFN-regulatoryfactor-dependentsignalingpathways.TLRshaveacentralroleininnateimmunityandarealsorequiredforthedevelopmentofanadaptiveimmuneresponse.TLRsareexpressedbyvariouscellsoftheimmunesystem,suchasmacrophagesanddendriticcells.TLRsareclassIreceptors,withasingleα-helixthatspansthecellmembrane.Theyrecognizeandrespondtomoleculesderivedfrombacterial,viralandfungalpathogens,suchaslipopolysaccharide(LPS)fromtheoutermembraneofGramnegativebacteria,peptidoglycanfragmentsfrombacterialcellwallsandsingle-strandedanddouble-strandedRNAfromviruses.
