In our research, we aimed at verifying the role of DnaK (the bacterial HSP70 homologue) as an immune activator in specific-pathogen-free (SPF) <i>Litopenaeus vannamei</i> either by injecting them with recombinant full length DnaK or a chemically synthetic 50 amino acid fragment peptide which is part of the peptide binding domain of DnaK (DnaK<sub>442–491</sub>). The expressions of two types of immune-related genes (transglutaminases and prophenoloxidases) were monitored via quantitative real time PCR (qPCR). The results showed that DnaK and DnaK<sub>442–491</sub> are able to significantly up-regulate transglutaminase-1 (TGase-1) and prophenoloxidase-2 (proPO-2) expressions within 12 h post injection. The synthetic peptide DnaK<sub>442–491</sub> is free of lipopolysaccharide (LPS) or any other bacterial components potentially contaminating a recombinant DnaK preparation. Hence the data suggested that DnaK, as such, stimulates the immune system of <i>L. vannamei</i> in a specific way (proPO-2, TGase-1). These findings indicate that DnaK is an efficient immune stimulator in <i>L. vannamei</i> immunity. It could be explored to modulate the expression of immune-related genes of <i>L. vannamei</i> potentially involved in mounting a response against infectious disease.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"Bacterial HSP70 (DnaK) is an efficient immune stimulator in <i>Litopenaeus vannamei</i>","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2024-12-10 01:33:01.897972","timezone_type":1,"timezone":"+01:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":"Recombinant DnaK; Chemically synthetic DnaK(442-491); Gene expression;Transglutaminase; Prophenoloxidase; Litopenaeus vannamei","OtherDescriptors":null,"Notes":null,"AnaPub":2014,"MonPub":null,"DateUpdate":"2018-08-17","DateCreate":"2014-05-18","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:000326978300013","VABBcode":null,"OpenAcc":0,"DOI":"10.1016/j.aquaculture.2013.10.008"},"refs":null,"anarec":{"AnaID":238105,"PubliDate":2014,"Pagination":"87-93","XtraPublOfAnaID":null,"ISBN":null,"Volume":"418-419","Issue":null,"BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":42190,"SerRR":"Aquaculture.
