简介:Objectiwe:InordertodetecttheroleofmonocytesinHSV-2infection,westudiedtheeffectofherpessim-plexVirus-2infectionontheproductionoftumorne-crosisfactor(TNF-α),interleukin-6(IL-6)secretedbymonocytes.Methods:MonocyteswereinfectedbyHSV-2(333Strain).Culturesupernatantswerecollectedat1,3,5,7dayspost-infection.ThelevelsofTNF-α,IL-6weremeasuredbyenzyme-linkedimmunosorbentas-say(ELISA).Results:ThelevelsofTNF-αsecretionbymono-cytessignificantlydecreasedonfirstdaypost-infection.ThelevelsofIL-6significantlydecreasedonfirstandthirddayspost-infection,andthengradu-allyincreasedtothecontrolonseventhdaypost-infection.Conclusions:TNF-αandIL-6productionbymono-cyteswasinhibitedduringHSV-2infection.Thepro-ductionofcytokinesmayplayanimportantroleinherpessimplexviurs-2pathogenicityandimmunity.
