Drug Design and Delivery for Intracellular Bacteria: Emerging Paradigms

Drug Development Research, Volume 86, Issue 8, December 2025.
ABSTRACT Intracellular bacteria exploit host cell niches, such as lysosomes, phagosomes, cytosol, entire cells, and even erythrocytes, to evade immune clearance and escape conventional antibiotics. These environments pose numerous therapeutic challenges, including crossing host cell membranes, navigating endosomal trafficking, tolerating acidic and ...
