Estimated Vaccine Effectiveness for Respiratory Syncytial Virus-Related Lower Respiratory Tract Disease.

Importance: Clinical trials have demonstrated high vaccine efficacy (VE) against lower respiratory tract disease (LRTD) but enrolled a smaller proportion of persons aged 75 years or older and those with comorbidities than seen in highest-risk populations in clinical practice settings. Additionally, VE against respiratory syncytial virus (RSV)-related hospitalizations and emergency department (ED) visits is not yet fully described.

Objective: To estimate Respiratory Syncytial Virus Prefusion F (RSVpreF) effectiveness in older adults.

The AMPK inhibitor overcomes the paradoxical effect of RAF inhibitors through blocking phospho-Ser-621 in the C terminus of CRAF.

The dimerization-driven paradoxical activation of RAF proto-oncogene Ser/Thr kinase (RAF) is the predominant cause of drug resistance and toxicity in cancer therapies with RAF inhibitors. The scaffold protein 14-3-3, which binds to the RAF C terminus, is essential for RAF activation under physiological conditions, but the molecular basis is unclear. Here we investigated whether and how 14-3-3 regulates the dimerization-driven transactivation of the RAF isoform CRAF by RAF inhibitors and affects drug resistance and toxicity by virtue of the dominant role of CRAF in these processes.
