Anti-CD83 Antibody is a humanized monoclonal antibody targeting CD83, a marker for mature dendritic cells (DCs). It interferes with immunomodulatory functions by specifically binding to the extracellular domain of CD83. The antibody works by depleting CD83+ cells or blocking costimulatory signals, serving as an advanced compound tool for studying immune tolerance induction, graft-versus-host disease (GvHD) suppression, and autoimmune disease treatment.
