The Claim

In non-human primates treated with interferon-alpha, gene expression changes in the putamen are strongly correlated with reduced dopamine levels, involving upregulation of synaptic signaling, glutamate receptor pathways, and PI3K/AKT and MAPK inflammatory cascades, and downregulation of oxidative phosphorylation and dopamine receptor signaling genes.

In plain English

In non-human primates given interferon-alpha, specific changes in gene activity in the putamen region of the brain occur alongside lower dopamine levels, including increased activity in inflammatory and synaptic signaling pathways and decreased activity in energy production and dopamine receptor pathways.

See the scientific wording

In non-human primates treated with interferon-alpha, gene expression changes in the putamen are strongly correlated with reduced dopamine levels, particularly involving upregulation of synaptic signaling, glutamate receptor pathways, and PI3K/AKT and MAPK inflammatory cascades, and downregulation of oxidative phosphorylation and dopamine receptor signaling genes.

Why this might work

Inflammation triggered by interferon-alpha shuts down the energy factories in brain cells, reduces the ability of dopamine receptors to respond, and overstimulates nerve signals with a toxic chemical, which together cause dopamine levels to drop without killing brain cells.

    When monkeys were given a drug that triggers inflammation, their brains showed changes in genes that control energy use and cell communication in a region linked to motivation—and these changes matched exactly how much their dopamine levels dropped. This means the inflammation directly messed with brain chemistry in a way that explains why they felt less motivated.
