Effects of Interleukin-1 and Tumor Necrosis Factor-α on Astrocytes, Microglia, Oligodendrocytes, and Glial Precursors in vitro

Merrill, J.E.·1991·Developmental Neuroscience

Abstract

Microglia and astrocytes undergo proliferative and differentiative changes in vivo after trauma or diseases such as multiple sclerosis (MS). Oligodendrocytes are destroyed in lesions in MS. Interleukin-1 (IL1) and tumor necrosis factor-alpha (TNF alpha) are involved in inflammation of the central nervous system and are elevated in MS. We have investigated the changes in cell morphology and cell number induced by IL1 and TNF alpha in purified and mixed populations of primary rat brain microglia, astrocytes, oligodendrocytes, and glial precursors. Depending on the target population, proliferation, differentiation, or inhibition of cultured cells was observed. The data also suggest that interactions among cell populations occur and support the hypothesis that IL1 and TNF alpha effects may be indirect, possibly through induction of other factors.

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.
