Abstract

The effects of low concentrations of extracellular ATP on cytosolic Ca 2+ , membrane potential, and transcription of IL-6 were studied in monocyte-derived human macrophages. During inflammation or infection many cells secrete ATP. We show here that application of 10 μM ATP or 10 μM UTP induces oscillations in cytosolic Ca 2+ with a frequency of ≈12 min -1 and oscillations in membrane potential. RT-PCR analysis showed expression of P2Y 1 , P2Y 2 , P2Y 11 , P2X 1 , P2X 4 , and P2X 7 receptors, large-conductance ( KCNMA1 and KCNMB1–4 ), and intermediate-conductance ( KCNN4 ) Ca 2+ -activated K + channels. The Ca 2+ oscillations were unchanged after removal of extracellular Ca 2+ , indicating that they were mainly due to movements of Ca 2+ between intracellular compartments. Comparison of the effects of different nucleotides suggests that the Ca 2+ oscillations were elicited by activation of P2Y 2 receptors coupled to phospholipase C. Patch–clamp experiments showed that ATP induced a transient depolarization, probably mediated by activation of P2X 4 receptors, followed by membrane potential oscillations due to opening of Ca 2+ -activated K + channels. We also found that 10 μM ATPγS increased transcription of IL-6 ≈40-fold within 2 h. This effect was abolished by blockade of P2Y receptors with 100 μM suramin. Our results suggest that ATP released from inflamed, damaged, or metabolically impaired cells represents a “danger signal” that plays a major role in activating the innate immune 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.
