CD154, also called CD40 ligand or CD40L, is a protein that is primarily expressed on activated T cells and is a member of the TNF superfamily of molecules. It binds to CD40 (protein) on antigen-presenting cells (APC), which leads to many effects depending on the target cell type. In total CD40L has three binding partners: CD40, α5β1 integrin and αIIbβ3. CD154 acts as a costimulatory molecule and is particularly important on a subset of T cells called T follicular helper cells (TFH cells). On TFH cells, CD154 promotes B cell maturation and function by engaging CD40 on the B cell surface and therefore facilitating cell-cell communication. A defect in this gene results in an inability to undergo immunoglobulin class switching and is associated with hyper IgM syndrome. Absence of CD154 also stops the formation of germinal centers and therefore prohibiting antibody affinity maturation, an important process in the adaptive immune system.
CD154 peptides and methods of reducing inflammation
ActiveUS12649775B2Peptide/protein ingredientsNGF/TNF-superfamilyImmunologic disordersDiabetes mellitus
The present invention provides methods and materials for treating and preventing autoimmune diseases. In particular, the present invention relates to the discovery that small peptides are capable of interacting with CD40, thereby interfering with the ability of CD40 to interact with CD154, which is important in inflammation. The present invention also relate to the use of such peptides in reducing the inflammatory response, and in particular, the autoimmune inflammatory response. The present invention also relates to the use of such short peptides to prevent or reverse autoimmune disease, and particular, diabetes, in individuals suffering from such disease. It also relates to methods and materials for detecting T-cells that express CD40 (Th40 cells). Also provided are kits for reducing inflammation, treating autoimmune diseases, or detecting Th40 cells.

The present disclosure relates to methods of treating or reducing the risk of transplant rejection or increasing a duration of time before transplant rejection occurs in a subject in need thereof (e.g., a human) by administering an antagonist that targets CD40 or CD154, such as an anti-CD40 antibody or an antigen-binding fragment thereof (e.g., a humanized anti-CD40 antibody or antigen-binding fragment thereof. The transplant may be an allogeneic or xenogeneic transplant (e.g., a cell, tissue, or organ or portion thereof).

The present disclosure relates to anti-CD40 antibodies, such as humanized anti-CD40 antibodies, that may be used in various therapeutic, prophylactic and diagnostic methods. The antibodies generally block the ability of CD40 to bind CD154 and do so without activating the cell expressing CD40 (e.g., a B cell). The present antibodies or fragments thereof may be used to reduce complications associated with organ or tissue transplantation.
