Traditional transfection agents including cationic lipids and polymers have high efficiency but cause cytotoxicity. While cell penetrating peptide based transfection agents exhibit improved cytotoxicity profiles, they do not have the efficiency of existing lipidic agents due to endosomal trapping. As

We investigated whether cytolytic melittin peptides could inhibit HIV-1 infectivity when carried in a nanoparticle construct that might be used as a topical vaginal virucide. Free melittin and melittin-loaded nanoparticles were prepared and compared for cytotoxicity and their ability to

Systemic bacterial infections are associated with high mortality. The access of bacteria or constituents thereof to systemic circulation induces the massive release of immunomodulatory mediators, ultimately causing tissue hypoperfusion and multiple-organ failure despite adequate antibiotic treatment.
