Ng regimens for drugsensitive TB, the combined inductive effects of RMP and EFV would need to be evaluated before enrolling participants taking EFV-based ART. Higher doses of bedaquiline in this setting could only be used if metabolite concentrations were in an acceptable range. Lastly, given that the PKI studies to date were conducted in healthy volunteers receiving single doses of bedaquiline an

We preincubated HIV-EBOZ GP virion-like particles (12,000 pg/ml) with PNGase F or endo H (10,000 U/ml each) diluted in DMEM or with DMEM alone for 1 hour at 37uC. Viruses then underwent gel electrophoresis;

Particles mixed withFigure 8. Proposed model of MBL-mediated macropinocytosis of EBOV. MBL carbohydrate recognition domains (CRD) bind to highly glycosylated mucin-rich regions of EBOV GP and the MBL-virion complex is presented to the cell surface. Then MBL binds to cognate cellular receptors, such as C1QBP or calreticulin [6] via MBL collagenous stalks. In this manner, MBL concentrates virus at t
