Abstract

Arachidonic acid (AA) can trigger activation of the phagocyte NADPH oxidase in a cell-free assay. However, a role for AA in activation of the oxidase in intact cells has not been established, nor has the AA generating enzyme critical to this process been identified. The human myeloid cell line PLB-985 was transfected to express p85 cytosolic phospholipase A2 (cPLA2) antisense mRNA and stable clones were selected that lack detectable cPLA2. cPLA2-deficient PLB-985 cells differentiate similarly to control PLB-985 cells in response to retinoic acid or 1,25-dihydroxyvitamin D3, indicating that cPLA2 is not involved in the differentiation process. Neither cPLA2 nor stimulated [3H]AA release were detectable in differentiated cPLA2-deficient PLB-985 cells, demonstrating that cPLA2 is the major type of PLA2 activated in phagocytic-like cells. Despite the normal synthesis of NADPH oxidase subunits during differentiation of cPLA2-deficient PLB-985 cells, these cells fail to activate NADPH oxidase in response to a variety of soluble and particulate stimuli, but the addition of exogenous AA fully restores oxidase activity. This establishes an essential requirement of cPLA2-generated AA for activation of phagocyte NADPH oxidase.

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.
