[email protected] Antibody-mediated rejection (AMR) in allograft transplantation APRIL (a proliferation-inducing ligand). These co-activation signals can be defined with a rapid increase in the levels of specific are required for B-cell differentiation into plasma cell and enhancing serological parameters after organ transplantation, presence of donor their posterior survival and are a key determinant of whether specific antibodies (DSAs) against human leukocyte antigen (HLA) developing B-cells will survive or die during the establishment molecules, blood group (ABO) antigens and/or endothelial cell of immuno-tolerance [5,6]. Important used agents commercially antigens (e.g. MICA, ECA, Vimentin, or ETAR) and also particular available are Tocilizumab (anti-IL6R) and Belimumab (BAFF). histological parameters [1,2]. If the AMR persists or progresses, the The receptors of BAFF and APRIL could also be important as treatment to eliminate the humoral component of acute rejection eventual targets, for example BAFF-R, TACI (transmembrane include three sequential steps: (a) steroid pulses, antibody removal activator and calcium modulator and cyclophyllin ligand interactor) (plasma exchange or immuno-adsorption) and high doses of and BCMA (B-cell maturation antigen).
