摘要:
Methods for inducing T-cell non-responsiveness to donor T-cells comprised in transplantation tissues are provided. The methods involve ex vivo treatment of donor T-cells with gp39 antagonists.
摘要:
The present disclosure features, inter alia, receptor-targeting reagents (e.g., immunotoxic receptor-targeting reagents), which are useful in, e.g., methods of binding a receptor-targeting reagent to a cell and methods for treating a variety of disorders such as, but not limited to, cancers and inflammatory disorders. Also featured are methods, compositions, and kits useful for selecting an appropriate treatment modality for a subject (e.g., a subject with a cancer or inflammatory disorder) and/or treating a variety of disorders such as cell proliferative disorders.

Disclosed herein are a monoclonal antibody that specifically binds to human CD 133 and single-chain variable fragments thereof. Also disclosed herein is a hybridoma that produces the monoclonal antibody that specifically binds to human CD133.
摘要:
Methods for inhibiting antigen-specific T cell responses by use of an agent which inhibits a costimulatory signal in T cells are disclosed. Preferably, both a first agent which inhibits a costimulatory signal in the T cell (e.g., a CTLA4Ig fusion protein) and a second agent which inhibits another T cell function, such as adhesion of the T cell to a cell presenting antigen to the T cell, are used to inhibit antigen-specific T cell responses. For example, to inhibit adhesion of a T cell to a cell presenting antigen, an anti-LFA-1 antibody can be used in conjunction with a CTLA4Ig fusion protein. Alternatively, another agent which inhibits a costimulatory signal in T cells, such as an anti-B7-1 antibody or an anti-B7-2 antibody can be used with a second agent which inhibits a proliferative signal in the T cell e.g., an anti-IL-2 receptor antibody. The methods of the invention are particularly useful for inhibiting graft versus host disease and for inhibiting rejection of a transplanted tissue or organ.
