Interest of Measuring P2X4 Receptors on Blood Monocytes as a Diagnostic Marker in Amyotrophic Lateral Sclerosis: P2X4 as a Diagnostic Biomarker for ALS

Amyotrophic lateral sclerosis (ALS) is the most common form of motor neuron disease and is characterized by the degeneration of motor neurons leading to progressive paralysis and death within 3 to 5 years after diagnosis. To date, no key mechanism had been identified. Our associated laboratory has identified the P2X4 purinergic pathway that appears to be involved in the pathogenesis of ALS. Our goal is to verify these results at the human level in order to have a proof of concept of P2X4's role as a biomarker of the disease.

Amyotrophic Lateral Sclerosis: A Multicenter Retrospective Observational Registry

This retrospective observational study will analyze de-identified clinical data from patients with amyotrophic lateral sclerosis (ALS) collected at multiple centers over 7 years. The primary objective is to describe disease progression using the ALS Functional Rating Scale-Revised (ALSFRS-R). Secondary objectives include evaluating survival, ventilatory decline, and correlations between available biomarkers (e.g., neurofilament light chain, cytokines) and disease trajectory. No new interventions or patient contact will occur.
