Langerhans cells are precommitted to immune tolerance induction

Langerhans cells are precommitted to immune tolerance induction.

Antigen-dependent interactions between T lymphocytes and dendritic cells (DCs) can produce two distinct outcomes: tolerance and immunity. It is generally considered that all DC subsets are capable of supporting both tolerogenic and immunogenic responses, depending on their exposure to activating signals. Here, we tested whether epidermal Langerhans cells (LCs) can support immunogenic responses ...

Cd4+Cd25+ Immune Regulatory Cells Are Required for Induction of Tolerance to Alloantigen via Costimulatory Blockade

Immune regulatory CD4(+)CD25(+) cells play a vital role in the induction and maintenance of self-tolerance and are essential for T cell homeostasis and the prevention of autoimmunity. Induction of tolerance to allogeneic donor grafts is a clinically desirable goal in bone marrow and solid organ transplantation. To determine whether CD4(+)CD25(+) cells regulate T cell responses to alloantigen an...

Immune tolerance induction in hemophilia

2015 The development of inhibitors is the main complication of hemophilia therapy. Inhibitors occur in 25–30% and in 2–5% of patients with severe hemophilia A and B, respectively. They render treatment and prevention of bleeds difficult. The only known therapeutic strategy able to eliminate inhibitors is immune tolerance induction (ITI) that consists in regular high-dose FVIII/FIX infusions. IT...

Induction by RelB-Silenced Dendritic Cells Immune Modulation and Tolerance

Low-Dose Immune Tolerance Induction in Hemophilia

In patients with hemophilia A and inhibitory alloantibodies against factor VIII, various dosage schedules are used to obtain immune tolerance. In this study, we have evaluated the results of 13 years of low-dose immune tolerance induction and factors that are predictive of a positive result. The effect of immune tolerance induction in relation to age at inhibitor development, number of exposure...
