✦ Synopsis

The humoral immune response constitutes an efficient system to protect the organism against diseases caused by invading pathogens. To guarantee a highly efficient defence, the humoral immune system has to be tightly regulated. Two cell subsets in particular, T cells and follicular dendritic cells (FDCs), contribute to the success of these regulation processes. Whereas the particular role of T cells is the elimination of autoreactive clones, the main role of FDCs is to present unprocessed antigen and check B-cell clones for higher affinity. B-cell clones unsuited for improved humoral immune response will be specifically killed. Involvement of Fas-mediated apoptosis might be an additional tool not only in T-cell-mediated regulation, but also in FDC-B cell interaction in the germinal centre.

## Background: In the chicken, circulating antigens enter the splenic white pulp via the schweigger-seidel sheaths (ellipsoids), where they are bound by cells, the ellipsoid associated cells (eac), which are located on the periphery of the ellipsoid. there is an increasing body of evidence that the
