Erratum: How self-tolerance and the immunosuppressive drug FK506 prevent B-cell mitogenesis

Generation of Epstein-Barr virus-specific cytotoxic T lymphocytes resistant to the immunosuppressive drug tacrolimus (FK506).

Adoptive transfer of autologous Epstein-Barr virus-specific cytotoxic T lymphocytes (EBV-CTLs) to solid organ transplant (SOT) recipients has been shown safe and effective for the treatment of EBV-associated posttransplantation lymphoproliferative disorders (PTLDs). SOT recipients, however, require the continuous administration of immunosuppressive drugs to prevent graft rejection, and these ag...

Involvement of NFAT1 in B cell self-tolerance.

B cells from anti-lysozyme Ig/soluble lysozyme double-transgenic mice are chronically exposed to self-Ag in the periphery, resulting in an anergic phenotype. Chronic exposure to self-Ag leads to nuclear translocation of NFAT1 and NFAT2, suggesting that they are involved in anergy. To directly test a role for NFAT1 in B cell anergy, NFAT1-deficient mice were crossed with anti-lysozyme Ig transge...

B cell tolerance to self in systemic autoimmunity.

After a century of research and despite intensive scrutiny, the origin of autoantibody production remains an enigma. Recently, the essential role of B cells in promoting systemic autoimmunity in mice seems more important than previously thought: self-reactive B cells can be subject to positive selection and a deficiency in serum IgM predisposes to the development of IgG antibodies to autoantige...

B-cell tolerance and autoimmunity

Self-reactive B cells are tolerized at various stages of B-cell development and differentiation, including the immature B-cell stage (central tolerance) and the germinal center (GC) B-cell stage, and B-cell tolerance involves various mechanisms such as deletion, anergy, and receptor editing. Self-reactive B cells generated by random immunoglobulin variable gene rearrangements are tolerized by c...
