Abstract:
:In the present investigations we aimed to study the effect of Shigella sonnei lipopolysaccharide (LPS) on delayed type hypersensitivity (DTH) to non-bacterial antigen in CBA mice. These experiments showed that intraperitoneal injection of phenol-water extracted LPS and avirulent S. sonnei did not affect the level of DTH. However, an injection of avirulent bacteria and LPS treated with 2-mercaptoethanol reduced significantly the levels of DTH. Gel filtration of redox-reactivated LPS through Sephadex G-200 shows that LPS contains three immunosuppressive components: approximately 800 kDa and higher, 150-200 and 50-70 kDa. These components differed by their specificity and heat-sensitivity.
