A specific CD4 epitope bound by tregalizumab mediates activation of regulatory T cells by a unique signaling pathway
CD4(+)CD25(+) regulatory T cells (Tregs) represent a specialized subpopulation of T cells, which are essential for maintaining peripheral tolerance and preventing autoimmunity. The immunomodulatory effects of Tregs depend on their activation status. Here we show that, in contrast to conventional anti-CD4 monoclonal antibodies (mAbs), the humanized CD4-specific monoclonal antibody tregalizumab (...
متن کاملTregalizumab – A Monoclonal Antibody to Target Regulatory T Cells
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...
متن کاملHigh thioredoxin-1 levels in rheumatoid arthritis patients diminish binding and signalling of the monoclonal antibody Tregalizumab
The humanized non-depleting anti-CD4 monoclonal antibody Tregalizumab (BT-061) is able to selectively activate the suppressive function of regulatory T cells and has been investigated up to phase IIb in clinical trials in patients suffering from rheumatoid arthritis (RA). A pharmacokinetic-pharmacodynamic model based on clinical data from RA and healthy volunteers, which used the cell surface C...
متن کاملAntibody induced CD4 down-modulation of T cells is site-specifically mediated by CD64+ cells
Treatment of PBMC with the CD4-specific mAb BT-061 induces CD4 down-modulation of T cells. Here we report that addition of BT-061 to purified T cells did not confer this effect, whereas incubation of T cells in BT-061 coated wells restored CD4 down-modulation. These results implied that Fcγ receptor mediated cell-cell interactions played a role. In consistence with this hypothesis PBMC depleted...
متن کاملAltered Suppressor Function of Regulatory T Cells in Type 1 Diabetes
Background: Type 1 diabetes (T1D) is a T cell mediated autoimmune disease targeting the insulin-producing β cells within pancreatic islets. Autoimmune diseases may develop as a consequence of altered balance between regulatory (Tregs) and autoreactive T cells. Objectives: To evaluate Treg cells frequency and suppressive function in the peripheral blood of newly diagnosed T1D patients in compari...
