Histopathology and immunophenotype of the spleen during acute antibody-mediated rejection.

Splenectomy has been reported to have a beneficial effect in treating Acute antibody-mediated rejection (ABMR). This reason for this often rapid and profound beneficial effect is not readily apparent from what is known about normal splenic immunoarchitecture. While the spleen is rich in mature B cells, it has not been noted to be a repository for direct antibody-secreting cells.
