Inhibition of entry of Toxoplasma gonldii into MDCK cells by fetal bovine serum
Tomplasma gondii의 숙주세포 침투를 억제하는 우태아혈청 성분
Abstract
We experienced the partial Inhibition of entry of Taxoplasma gondii Into MDCK cells when the FBS was depleted from media. MDCK cells and Toxoplasma (RH strains) were co-cultured, the penetration was inhibited up to 60-80% with concentration-dependence of FBS. Inhibitory effect was clear when the conc. of FBS was over 1% (v/v) with 50% inhibition comic. of 5%. When ToxopLosma was pre-incubated with FBS and then applied to MDCK cells, there were no inhibitory effect, but when FBS was added to Toxoplasma- MDCK co-culture, the time of adding was c10cal with rapid inhibition. And when FBS was further treated with heat (
우태아혈청의 성분이 Toxoplasma의 숙주세포 침투를 억제하는 현상을 보여 이를 보고하고자 한다. MDCK세포를 숙주로 하여 Toxoplasma의 RH주를 첨가하였을 때, 우태아혈청 농도 1%(v/v) 에서 억제 효과가 나타나기 시작하여 5%일때 침투능을 반감시켰다. 우태아절청의 비동화 여부는 억제 효과에 영향을 미치지 못하였으며, 우태아혈청을
