A new study found that combining two treatments—one that fixes the faulty SMN2 gene and another that blocks an enzyme called HDAC6—greatly improved muscle strength and survival in a mouse model of spinal muscular atrophy (SMA). This is important because it offers a potential way to help SMA patients who still face muscle weakness even after receiving newer gene therapies.

Key Highlights

•

 

Un estudio ha desarrollado una nanopartícula dirigida al riñón que administra formoterol, mitigando la enfermedad renal diabética en modelos animales sin provocar los efectos cardíacos adversos típicos de los beta-agonistas sistémicos. Este hallazgo es importante porque ofrece una nueva estrategia farmacológica para tratar la nefropatía diabética, una complicación grave de la diabetes, separando la eficacia renal de la toxicidad cardiovascular.

Un nuevo estudio advierte que las herramientas estándar para evaluar modelos farmacocinéticos, como la “visual predictive check” (VPC), pueden ser engañosas al aplicarse a datos del mundo real, mostrando errores aparentes incluso cuando el modelo es correcto debido a prácticas clínicas como el ajuste de dosis. Esto es significativo porque subraya la necesidad de desarrollar nuevos diagnósticos más robustos para el análisis de datos farmacológicos complejos provenientes de la práctica clínica rutinaria.

Una revisión publicada en Alzheimer’s & Dementia explora el acoplamiento entre los ritmos circadianos y el metabolismo del NAD+ en la demencia, detallando cómo las vías moleculares que involucran al NAD+ y las sirtuinas se deterioran en enfermedades neurodegenerativas. Este trabajo es relevante porque propone que restaurar los niveles de NAD+ mediante estrategias farmacológicas (como el uso de precursores) o cambios en el estilo de vida podría ser una diana terapéutica para mejorar el sueño y la cognición en la demencia.
