  • MAGL is the main enzyme in the brain responsible for the hydrolysis of >85% 2-AG into AA, a precursor of bioactive oxylipins.

    “MAGL is the main enzyme in the brain responsible for the hydrolysis of >85% 2-AG into AA, a precursor of bioactive oxylipins63,75.”

    From Foamy microglia link oxylipins to disease progression in multiple sclerosis (2026) · cites this paper as [63]

    The indexed passage labeled Abstract (page unavailable) identifies MAGL as hydrolyzing brain 2-AG and reports that disrupting it raises 2-AG while lowering AA and downstream eicosanoids. This supports the pathway and MAGL’s major role, but our copy does not give the claimed >85% share of 2-AG hydrolysis. (LLM, conf=0.88)

  • Oxidized signaling lipids act as chemoattractants for adaptive immune cells, potentially driving T cell and B cell infiltration, enhancing TH17 cell and plasma cell differentiation, and increasing immunoglobulin production, collectively contributing to neuroinflammation and a sustained demyelinating milieu.

    “These oxidized signaling lipids act as chemoattractants for adaptive immune cells, potentially driving T cell and B cell infiltration33, enhancing TH17 cell76 and plasma cell differentiation, and increasing immunoglobulin production, collectively contributing to neuroinflammation and a sustained demyelinating milieu63,77–81.”

  • MAGL catalyzes the conversion of 2-arachidonoylglycerol into arachidonic acid in the brain, which is a precursor for oxylipins.

    “MAGL catalyzes the conversion of the endocannabinoid (eCB) 2-arachidonoylglycerol (2-AG) into arachidonic acid (AA) in the brain, which is a precursor for oxylipins33,63”
  • MAGL is the primary hydrolytic enzyme for 2-AG and a rate-limiting enzyme in the production of free arachidonic acid in brain, liver, and lung, but not in the gastrointestinal tract or other organs.

    “In addition to being the primary hydrolytic enzyme for 2-AG (Dinh et al, 2002), MAGL is a rate-limiting enzyme in the production of free arachidonic acid in brain, liver, and lung, but not in the gastrointestinal tract or other organs (Nomura et al, 2011).”

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.
