Abstract

In experimental autoimmune encephalomyelitis, the acute phase of the disease is produced by T‐helper lymphocyte type 1 (T H 1), which produces mainly TNFα and IFNγ. Recovery from the disease is mediated by T‐helper lymphocyte types 2 and 3 (T H 2/T H 3), which, among other cytokines, produce transforming growth factor β (TGFβ). To address the influence of TGFβ on T H 1‐induced gene expression, microarray technology was used on murine primary microglial cells stimulated with IFNγ and TNFα in the absence or presence of TGFβ. The resulting data from an investigation of up to 5,500 genes provided the notion that TGFβ prevents the induction of a proinflammatory gene program within microglia exposed to a T H 1 milieu. T H 1 cytokines upregulated 175 genes comprising cytokine, chemokine, and genes involved in host response to infection and the TNFα/IFNγ intracellular signaling pathway. It is observed that TGFβ inhibits expression of 25% of the TNFα/IFNγ‐induced genes and a further 66 TNFα/IFNγ‐independent genes. The focus of TGFβ inhibition is observed to be directed in genes involved in chemotaxis (IL‐15, CXCL1, CXCL2, CCL3, CCL4, CCL5, CCL9), chemokine receptors (CCR5, CCR9), LIF receptor, and FPR2, and on genes mediating cell migration (MMP9, MMP13, MacMARCKS, endothelin receptor B, Ena/VASP, Gas7), apoptosis (FAS, TNF, TNF receptor, caspase‐1 and ‐11), and host response to infection (toll‐like receptor 6, Mx‐1, and MARCO). Taken collectively, the data strongly suggest that one of the main effects of TGFβ is to impair cell entry into the CNS and to hinder migration of microglia in the CNS parenchyma. © 2003 Wiley‐Liss, Inc.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
