Si un análisis de sangre permitiera separar pacientes por su causa biológica, los ensayos de medicamentos podrían dirigirse a quienes realmente se beneficiarían. Para alguien de acá que convive con la enfermedad, esto abre la puerta a terapias más personalizadas en el futuro. Pero todavía es un estudio previo a la aplicación clínica y necesita validación en otras poblaciones.","quienFirma":"Investigadores del proyecto ORIGIN-PD (institución no especificada en el resumen)","confianza":"preprint","consulta":null},"sello":{"hash":"8dc94331a9ee36a9a95d2bd4b97072edec15ce96f89c30c77fe699980d34549a","sello":"2938b7dd2121ceff135c37782c7c0310a1b0a7d77c51c1f2064582678a723747","beacon":{"drand":{"cadena":"8990e7a9aaed2ffed73dbd7092123d6f289930540d7651336225dc172e51b2ce","ronda":6569549,"aleatorio":"40f90a7c24002ff2f2230484261fe0762689a5f23536372bd9ca78a1043380ae","tiempo":"2026-10-20T17:31:30.000Z"},"nist":{"cadena":2,"pulso":1991980,"salida":"69E07DFEE11EFF4D62E2205CD9F3F399D52FEF236584C85A7AE96BEA74AB3905C910288488E7107D6A6068B76293A18CD91AD3E13518452A6064E4922DB00D59","tiempo":"2026-10-20T17:31:00.000Z"},"noAntes":"2026-10-20T17:31:30.000Z"},"verificacion":{"drand":true,"nist":true},"tsa":{"time":"Oct 20 17:31:39 2026 GMT","provider":"freetsa.org","sobre":"sello"},"original":{"titulo":"An interpretable whole-blood transcriptomic model for Parkinson disease identification and molecular profiling","descripcion":"Background Sporadic Parkinson disease (PD) lacks a molecular taxonomy that stratifies patients by dominant molecular drivers, limiting enrollment for disease-modifying trials, especially anti-inflammatory agents targeting NLRP3/NF-{kappa}B. Methods We developed ORIGIN-PD, an interpretable whole-blood transcriptomic classifier comprising 34 gene-level features and a composite low-expression score, with gene-level contributions organized into eight prespecified functional modules: midbrain dopaminergic (mDA) neuron identity/development, pathway-related, oxidative/mitochondrial, proteostasis, inflammation/ immunity, microglia, ncRNA, and other.
