Biologic activities of the murine beta -chemokine TCA3.

Abstract

The murine beta-chemokine TCA3 was purified to homogeneity. The biologic activities of the purified glycoprotein were evaluated in vivo and in vitro. Mice injected i.p. with 1- to 100-ng purified rTCA3 exhibited a rapid influx of neutrophils and macrophages. Increased numbers of neutrophils and monocytes were observed in peripheral blood within 15 min and peak at 45 min. After 45 min neutrophil and macrophage levels were increased in the peritoneal exudate with peak levels occurring at 2 h, followed by a subsequent decline by 24 h. Inflammatory responses were induced in a dose-dependent fashion. The in vivo inflammatory responses were mirrored by the pattern of TCA3-induced chemotaxis in vitro. Neutrophils and macrophages responded to similar concentrations of TCA3 (3 x 10(-9) to 10(-8) M). Lymph node cells responded to other chemokines but did not migrate to TCA3. We also demonstrated that rTCA3 stimulates a transient increase in cytoplasmic free calcium in monocytic cells through a PTX-sensitive pathway. Cross-desensitization studies indicate that TCA3 acts independently of other beta-chemokines (MIP-1 alpha and RANTES) and the alpha-chemokine IL-8. Furthermore, TCA3 does not induce a Ca2+ flux in cells transfected with cDNA for the C-C CKR-1 chemokine receptor, supporting the conclusion that there are distinct receptors for TCA3.

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.
