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.

Source: Natural killer loops: pyruvate in, lactate out

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.

How it works
1 study reviewed
In plain English

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.

Why this might work

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.

  1. Study: 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.
