Abstract

The chemokine beta family is comprised of at least six distinct cytokines that regulate trafficking of phagocytes and lymphocytes in mammalian species; at least one of these, macrophage inflammatory protein 1 alpha (MIP-1 alpha), also regulates the growth of hematopoietic stem cells. We now show that MIP-1 alpha and the related beta chemokine, RANTES, induce transient alterations in intracellular Ca2+ concentration in polymorphonuclear leukocytes that can be reciprocally and specifically desensitized, suggesting a common receptor. Moreover, we have now cloned both the cDNA and the gene for this receptor, functionally expressed the receptor in Xenopus oocytes, and mapped the gene to human chromosome 3p21. Transcripts for the receptor were found in mature and immature myeloid cells as well as B cells. The receptor is a member of the G protein-coupled receptor superfamily. It has approximately 33% amino acid identity with receptors for the alpha chemokine, interleukin 8, and may be the human homologue of the product of US28, an open reading frame of human cytomegalovirus.

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.
