CAT and tuberculosis: Hu and colleagues explored a strategy targeting hypoxia to enhance TB treatment using ultrasound‐driven PLGA nanoparticles loaded with levofloxacin (LEV) and catalase (CAT).[104] These nanoparticles, created through double emulsification, demonstrated oxygen production, biocompatibility, and safety in a mouse model of subcutaneous TB granulomas induced by Bacille Calmette‐Guérin (BCG) (Figure7a,b).
