The Claim
Human CD56Dim natural killer cells take up exogenous pyruvate and convert it to lactate in the cytosol to regenerate NAD+, thereby sustaining glycolytic flux and supporting mitochondrial energy production via the citrate–malate shuttle.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
Human CD56Dim natural killer cells import pyruvate from outside the cell, convert it to lactate inside the cytoplasm to restore NAD+ levels, maintain glycolysis, and enable mitochondrial energy production through the citrate–malate shuttle.
See the scientific wording
Human CD56Dim natural killer cells take up exogenous pyruvate and convert it to lactate in the cytosol to regenerate NAD+, thereby sustaining glycolytic flux and supporting mitochondrial energy production via the citrate–malate shuttle.
CD56Dim natural killer cells take in pyruvate from their surroundings, turn it into lactate inside the cell to recycle a key energy molecule called NAD+, which keeps sugar breakdown going; at the same time, parts of that pyruvate enter the mitochondria and are used to produce energy through a shuttle system that moves carbon between the cytoplasm and mitochondria.
What the research says
1 studyStudy: Natural killer loops: pyruvate in, lactate out
This study shows that a type of immune cell uses pyruvate from its surroundings to make lactate, which helps the cell keep breaking down sugar for energy and keeps its power plants (mitochondria) running. It’s like recycling a key tool to keep the energy factory going.
