  ABSTRACT: To explore the feasibility of oral immune tolerance of systemic lupus erythematosus (SLE)-like model induced by nucleosomal Th cell epitope via the attenuated Salmonella typhimurium. SLE-like murine model was established by immunization with apoptotic syngeneic lymphocytes. The recombinant strains were orally administrated to induce immune tolerance. The levels of serum autoantibodies, such as anti-ANA, ds-DNA, and antinucleosome antibody, leukopenia, proteinuria and kidney injuries were evaluated. SLE-like murine model was successfully established. Compared with controls, it was shown that CTLA4-Ig-H2B group could dramatically reduce the levels of serum autoantibodies, such as anti-ANA, ds-DNA and antinucleosome antibody and ameliorate leukopenia and proteinuria (all P < 0.05). Immune complex deposits of IgG in glomeruli were lower in CTLA4-Ig-H2B (1.35 +/- 0.16) than in CTLA4-Ig (1.66 +/- 0.23) and H2B (1.69 +/- 0.24) (both P < 0.05). The score of glomeruli lesion of CTLA4-Ig-H2B (1.26 +/- 0.14) was significantly lower than those of CTLA4-Ig (1.73 +/- 0.25) and H2B (1.71 +/- 0.20) (both P < 0.05). Combined with CTLA4-Ig, it is feasible to induce oral immune tolerance of SLE models with nucleosomal Th cell epitope via the attenuated Salmonella typhimurium. This may provide a novel way to prevent and treat SLE by oral immune tolerance.

  ABSTRACT: To investigate the possibility of hair follicle reformation induced by dermal papilla cells in vivo and in vitro. Dermal papilla cells, dermal sheath cells obtained from human scalp skin by enzyme digestion were mixed with collagen to form mesenchymal cell-populated collagen gels. Superior and inferior epithelial cells and bulb matrical cells were then cultured on these gels by organotypic culture to recombine bilayer artificial skins. Dermal papilla cells and outer root sheath keratinocytes were mingled together and transplanted under subcutaneous tissue of the dorsal skin of nude mice. The results of histologic examination was observed with HE stain. These recombinants by organotypic culture all reformed bilayer structure like nature skin. Hair follicle-like structure reformation was found in dermal sheath cell-populated collagen gel when combined with superior or inferior epithelial cells. Dermal papilla cells also induced superior and inferior epithelial cells to form hair follicle on nude mice. Low passage dermal papilla cells mixed with hair follicle epithelial cells reformed many typical hair follicle structures and produced hair fibres after transplantation on nude mice. The dermal part of hair follicle, such as dermal papilla cells and dermal sheath cells, has the ability to induce hair follicle formation by interaction with the epithelial cells of hair follicle.
