Mycosis fungoides. Activated CD4+ T lymphocytes stimulate monocytes, macrophages and synovial fibroblasts to elaborate the cytokines interleukin-1, interleukin-6 and tumour necrosis factor alpha (TNFa), and to secrete metalloproteinases. For example, cytotoxic T cells have been shown to become activated when targeted by other CD8 T cells leading to tolerization of the latter.[12].
