Lupus nephritis is one of most severe complications systemic erythematosus lupus (SLE) and current approaches are not curative for nephritis. Although CD4+Foxp3+ regulatory T cells crucial prevention autoimmunity, the therapeutic effect these on satisfactory. We previously reported that CD8+CD103+ induced ex vivo with TGF-β1 IL-2 (CD8+CD103+ iTreg), regardless Foxp3 expression, displayed potent immunosuppressive Th cell response had cell-mediated colitis. Here, we tested whether iTreg can...

The age-specific seroclearance pattern of hepatitis B surface antigen (HBsAg) in chronic virus (HBV) infections China remains unclear. In this study, based on three national serosurvey data China, we propose an age- and time-dependent discrete model use the method non-linear least squares to estimate annual rate HBsAg seroclearance. We found that HBV aged 1-59 years occurred at average 1.80% (95% CI, 1.54-2.06%) from 1993 2006. predominantly early childhood, 20-24 35-39 year age groups....
