The elimination of autoreactive T cells in the thymus involves the process of programmed cell death. Animal model studies, using the lpr and gld strains of mice, have identified FAS receptor (FAS) and FAS ligand (FAS-L) as important components of this mechanism. Whether FAS and FAS-L are also implic

โฆ Synopsis
Autoimmune diseases reflect the confluence of genetic, environmental and stochastic events. Recent studies have implicated apoptotic cell death pathways in initiating and propagating autoimmune diseases, as well as in rendering individuals susceptible to such diseases. Similar to autoimmunity, apoptosis is a multistep process, affecting immune and target cells, integrating numerous intrinsic and extrinsic signals, and requiring the actions of multiple gene products. Particularly relevant to the complexity of autoimmunity are the recent observations that apoptotic death might provide a primary source of tolerogen to shape the immune repertoire, or be the target of the immune response in autoimmunity, and that apoptosis is both required for lymphocyte selection and immunoregulation, and is a prominent outcome of immune and inflammatory effector pathways.

Recent neuropathological studies of experimental autoimmune encephalomyelitis have focused attention on the high number of cells in the lesions that show typical morphological features of apoptosis. Surprisingly, it has turned out that the vast majority of apoptotic cells are T lymphocytes and that
The relationship between Fas-mediated apoptosis and Type 1 diabetes is currently under investigation. Fas/Fas ligand interaction could be involved both in the insulitis process and in beta-cell death. Nevertheless, different mechanisms appear to be involved in human Type 1 diabetes and in NOD mice.
Combining in situ tailing and immunocytochemical staining, we demonstrated that the infiltrating macrophages in muscle tissue sections during early phase of experimental autoimmune myasthenia gravis (EAMG) in Lewis rats were eliminated by apoptosis at high frequency. These apoptotic macrophages were
