WebApr 9, 2024 · Type II toxins are typically phospholipases or pore-forming cytotoxins that disrupt the integrity of eukaryotic cell membranes. Damages host cells release danger-associated molecular patterns (DAMPs) that bind to pattern-recognition receptors (PRRs) causing the release of inflammatory cytokines. WebStudies using multilamellar liposomes (10, 22) and planar lipid bilayers (24) have demonstrated that the cytolytic action of Cyt1A is mediated by the toxin-lipid interaction. This is in clear contrast with the receptor-mediated insecticidal action …
