Effects of inflammatory cytokines IFN-γ, TNF-α and IL-6 on the viability and functionality of human pluripotent stem cell-derived neural cells
Abstract
Multiple Sclerosis (MS) is an inflammatory neurodegenerative disease, where neural progenitor cell (NPC) transplantation has been suggested as a potential neuroprotective therapeutic strategy. Since the effect of inflammation on NPCs is poorly known, their effect on the survival and functionality of human NPCs were studied. Treatment with interleukin (IL)-6, tumor necrosis factor (TNF)-α and interferon (IFN)-γ did not induced cytotoxicity, but IFN-γ treatment showed decreased proliferation and neuronal migration. By contrast, increased proliferation and inhibition of electrical activity were detected after TNF-α treatment. Treatments induced secretion of inflammatory factors. Inflammatory cytokines appear to modulate proliferation as well as the cellular and functional properties of human NPCs.

•NO inhibits the expression of the inflammatory cytokines IL-1β, TNF-α, IL-6, and IFN-γ in lymphocytes, eosinophils, and monocytes, in an effect mediated by nitrosylation of the transcription factors JAK/STAT and NF-κβ.
“Also, •NO inhibits the expression of the inflammatory cytokines IL-1β, TNF-α, IL-6, IFN-γ [116] in lymphocytes, eosinophils, and monocytes, in an effect mediated by nitrosylation of the transcription factors JAK/STAT (Janus Kinase/Signal Transducer and Activator of Transcription) and NF-κβ [117].”

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.
