RIPK3 and thymus lymphoma: Necroptosis has also been shown to contribute to the maintenance of T cell homeostasis.[15] For example, the elimination of excessive and abnormally proliferating T lymphocytes in the absence of caspase‐8 occurs via necroptosis.[16] Along these lines, it has been reported that abnormal proliferation of cells present in the thymus leads to lymphoblastic thymic lymphoma.[17] This suggests the possibility that a deficiency in the RIPK3‐mediated necroptosis pathway may contribute to the pathogenesis of thymic lymphoma.
