主　　题：porcine epidemic diarrhea virus(PEDV) next-generation sequencing(NGS) single-cell RT-PCR antibody repertoire 

摘      要：Porcine epidemic diarrhea virus(PEDV)is the most common diarrhea-causing pathogen in newborn *** clarifications of the overall antibody repertoire and antigen-specific antibody repertoire are essential to provide important insights into the B-cell response and reshape new ***,we applied next-generation sequencing(NGS)technology to investigate immunoglobulin(Ig)variable(V)gene segment usage of swine B-cells from peripheral blood lymphocytes(PBL)and mesenteric lymph node(MLN)cells following PEDV *** identified the transcripts of all functional Ig V-genes in antibody ***1 S2,IgKV1-11,and IgLV3-4 were the most prevalent gene segments for heavy,kappa,and lambda chains,respectively,in PBL and *** previous studies,IgKV1,instead of IgKV2,and IgLV3,instead of IgLV8,were the prevalent Ig V-gene families for kappa and lambda light chains,*** further examined the antibody repertoire of PEDV spike-specific B cells by single-cell *** contrast to the overall antibody repertoire,Ig V-gene segments of PEDV spike-specific B cells preferentially adopted IgHV1-4 and IgHV1-14 for heavy chain,IgKV1-11 for kappa chain,and IgLV3-3 for lambda *** results represent a comprehensive analysis to characterize the Ig V-gene segment usage in the overall and PEDV spike-specific antibody repertoire in PBL and MLN.
