Comparing 2 hypotheses side-by-side
Pathogenic gut bacteria prime peripheral macrophages through NLRP3 inflammasome activation, creating a systemic pro-inflammatory state that enhances neuroinflammation and dopaminergic neuron vulnerability. Selective inflammasome inhibitors combined with microbiome restoration could break this inflammatory cycle.
Specific commensal bacteria activate vagal afferent neurons through GLP-1 receptor signaling, promoting neuroprotective pathways in the brainstem and substantia nigra. Targeted vagal stimulation combined with GLP-1 receptor agonists could enhance endogenous neuroprotection.
This summary checks where the selected hypotheses point toward the same target or mechanism, and where they pull in opposite directions.
