Olsson T, 1995, Cytokine-producing cells in experimental autoimmune encephalomyelitis and multiple sclerosis., Neurology, Vol: 45, Pages: S11-S15, ISSN: 0028-3878

In both multiple sclerosis (MS) and experimental autoimmune encephalomyelitis, the regulation of the cytokine spectrum and production is likely to have a decisive influence on disease outcome. Studies of cytokines, however, are hampered by the autocrine or paracrine nature of cytokines. Studies of cellular production by messenger RNA detection or cellular secretion are therefore necessary. Collective data suggest that certain cytokines associated with the TH1 phenotype or lymphocytes, such as tumor necrosis factor alpha, lymphotoxin, interleukin-12, and interferon gamma, may promote disease, while cytokines produced by the TH2 subset, such as interleukin-10, may limit disease. In addition, transforming growth factor beta is a putative disease downregulator. Increased knowledge in this field will likely lead to improved therapy for MS patients.

We used an ovalbumin (OVA)-specific alpha beta-TCR transgenic mouse system to examine the cellular basis of CD4+ T helper (Th) phenotype development in vitro. Heat-killed Listeria monocytogenes (HKLM) strongly promotes the in vitro development of a Th1 phenotype in OVA-specific transgenic T cells. Listeria monocytogenes effects to promote the Th1 phenotype are antigen presenting cell (APC) dependent and occur when splenic APCs, but not the B cell hybridoma TA3, are present during T cell activation. However, addition of FACS-sorted macrophages to TA3 activated cultures restores the ability of Listeria to induce Th1 development. This effect on T cell development does not require MHC-restricted antigen presentation by macrophages, but may act through soluble factors. Although the presence of interferon gamma is necessary for Listeria induction of Th1 development, IFN-gamma alone is insufficient to induce Th1 development. Furthermore, Listeria induction of the Th1 phenotype does not require several known products of activated macrophages, including interleukin-1 (IL-1), tumor necrosis factor (TNF-alpha), IL-6, or nitric oxide. Although transforming growth factor-beta (TGF-beta) may mediate some Listeria effects, it does not fully reconstitute Listeria effects to promote Th1 development. In summary, host interactions with bacterial pathogens can affect the development of specific Th subsets, allowing innate immune cells to direct development of specific immune phenotype. For Listeria monocytogenes, the induction of the Th1 phenotype may involve a novel cytokine distinct from several known factors produced by activated macrophages.

In the three years since its discovery, the pleiotropic cytokine interleukin-10 (IL-10) has been implicated as an important regulator of the functions of lymphoid and myeloid cells. IL-10's ability to block activation of cytokine synthesis and several accessory cell functions of macrophage renders this cytokine a potent suppressor of the effector functions of macrophages, T cells, and NK cells. In addition, IL-10 likely contributes to regulating proliferation and differentiation of B cells, mast cells, and thymocytes. The Epstein-Barr virus genome encodes a homolog of IL-10 (BCFR1, viral IL-10, vIL-10) which shares many of the cellular cytokine's biological activities and may therefore play a role in the host-virus interaction. This article reviews current studies of IL-10's biological activities and discusses its possible roles in regulation of immune responses.
