Non-depleting anti-CD4 monoclonal antibody induces immune tolerance to ERT in a murine model of Pompe disease
نویسندگان
چکیده
Approximately 35-40% of patients with classic infantile Pompe disease treated with enzyme replacement therapy (ERT) develop high, sustained antibody titers against the therapeutic enzyme alglucosidase alfa, which abrogates the treatment efficacy. Induction of antigen-specific immune tolerance would greatly enhance ERT for these patients. Here we show that a short-course treatment with non-depleting anti-CD4 monoclonal antibody successfully induced long-term ERT-specific immune tolerance in Pompe disease mice. Our data suggest an effective adjuvant therapy to ERT.

Immune modulation in Pompe disease treated with enzyme replacement therapy.
Pompe disease is a lysosomal storage disease characterized by massive glycogen deposition in skeletal, cardiac and smooth muscle secondary to the deficiency of acid α-glucosidase (GAA) [1]. Once rapidly fatal, it has become a treatable condition since the development of enzyme replacement therapy (ERT) with alglucosidase α (recombinant human GAA [rhGAA], Myozyme/Lumizyme Genzyme Corp. Cambridge...
متن کاملLow-Dose Liver-Targeted Gene Therapy for Pompe Disease Enhances Therapeutic Efficacy of ERT via Immune Tolerance Induction
Pompe disease results from acid α-glucosidase (GAA) deficiency, and enzyme replacement therapy (ERT) with recombinant human (rh) GAA has clinical benefits, although its limitations include the short half-life of GAA and the formation of antibody responses. The present study compared the efficacy of ERT against gene transfer with an adeno-associated viral (AAV) vector containing a liver-specific...
متن کاملOral tolerance for delayed type hypersensitivity contribution of local and peripheral mechanisms
Oral tolerance is a physiological immune mechanism, which controls the outcome of deleterious hypersensitivity reactions to environmental antigens absorbed through the gastrointestinal tract, and maintains homeostasis. Using a mouse model of oral tolerance of delayed type hypersensitivity to contact allergens, i.e. haptens, we have examined the mechanisms involved in the induction of oral toler...

Regulatory T cells (Tregs) represent a subpopulation of CD4(+) T cells, which are essential for the maintenance of immunological tolerance. The absence or dysfunction of Tregs can lead to autoimmunity and allergies. The restoration of functional Tregs and/or Treg cell numbers represents a novel and attractive approach for the treatment of autoimmune diseases, e.g., rheumatoid arthritis (RA). Th...

BACKGROUND Rheumatoid Arthritis (RA) is a chronic immune mediated disease associated with deregulation of many cell types. It has been reported that different T cell subsets have opposite effects in disease pathogenesis, in particular Th17 and Treg cells. METHODOLOGY AND FINDINGS We investigated whether non-depleting anti-CD4 monoclonal antibodies, which have been reported as pro-tolerogenic,...
