Neutralizing these toxins offers a promising therapeutic avenue to mitigate infection symptoms and slow disease progression. Recent research highlights the potential of host-inspired strategies targeting toxin-membrane interactions. Statins and oxysterols disrupt intracellular cholesterol synthesis and trafficking to reduce its abundance in cell membranes, mimicking natural cellular defenses against PFTs. Aminosterols alter membrane properties to hinder toxin binding and pore formation. Nanoparticle-based decoys, such as artificial liposomes composed of the lipids cholesterol and sphingomyelin or recycled cell membranes, act as toxin traps, sequestering PFTs to protect host tissues. These nanoparticles demonstrate broad-spectrum efficacy across many bacterial species and offer additional functions, such as scavenging inflammatory cytokines. This review evaluates the clinical potential of these emerging treatment strategies and discusses the advantages of leveraging host factors to mitigate bacterial virulence rather than directly targeting toxins. Such host-inspired approaches represent a novel and complementary addition to the arsenal against antibiotic-resistant bacterial pathogens.enPore-forming toxinscholesterolhost-directed therapynanoparticlesstatins600 - Technology::610 - Medicine & healtharticle10.48620/934704144733910.1080/1040841X.2025.2605546
