Target Information
Chicken T-Cell-Specific Surface Glycoprotein CD28 Homolog (CD28) is a crucial protein involved in T-cell activation and immune response regulation. It is a cell adhesion molecule of the immunoglobulin superfamily, expressed on most peripheral blood T lymphocytes. CD28 provides a critical second activation signal for T cells by binding to CD80 and CD86, which are expressed by antigen-presenting cells. This interaction is essential for T-cell proliferation, cytokine production, and preventing T cells from entering an anergic state or undergoing premature apoptosis. In chickens, CD28 plays a key role in maintaining immune system function and has been implicated in various immune-related diseases.
