Abstract

The type beta transforming growth factors (TGF) are potent regulators of the growth and functions of lymphocytes and macrophages. Recently the human glioblastoma cell line 308 was shown to produce TGF-beta 2. The relevance of this finding was evaluated further by comparing human glioblastoma cells with their nontransformed animal counterpart, astrocytes, with regard to the production of the three TGF-beta isoforms observed so far in mammals. In this report astrocytes are demonstrated to secrete also TGF-beta 2 and to express TGF-beta 1, -beta 2, and -beta 3 mRNA in vitro. In contrast, cultured murine brain macrophages release TGF-beta 1 and are positive for TGF-beta 1 mRNA only. Glia cell-derived TGF-beta 1 and -beta 2 are detected in latent form whereas both latent and active TGF-beta are identified in the supernatant of three human glioblastoma cell lines tested. These cell lines, however, show heterogeneity in regard to the isoform of TGF-beta expressed but share with astrocytes the inability to release TGF-beta 3. Provided production and activation of latent TGF-beta occur in vivo, astrocytes and microglia may then be expected to exert regulatory influences on immune mediated diseases of the central nervous system.

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.
