1.MECHANISM OF ACTION
The primary mechanism of CRAMP (mouse) involves a dual-action strategy combining direct microbial membrane disruption with complex immunomodulatory signaling through specific G-protein-coupled receptors. Initially, the cationic peptide is electrostatically attracted to the negatively charged phospholipids of microbial membranes, where it adopts an amphipathic alpha-helical conformation and inserts into the lipid bilayer to form toroidal pores or a carpet-like structure, leading to rapid depolarization, uncontrolled ion flux, and osmotic lysis of target bacteria, fungi, or enveloped viruses. Concurrently, CRAMP interacts with host cell receptors such as Fpr2 (Formyl Peptide Receptor 2) on immune and epithelial cells, triggering intracellular calcium mobilization, MAPK pathway activation, and the subsequent chemotaxis of neutrophils, monocytes, and macrophages to sites of infection or injury. This receptor-mediated activity also enables the peptide to neutralize bacterial endotoxins like LPS, modulate cytokine production (including TNF-α and IL-6), and promote downstream processes such as angiogenesis and re-epithelialization during tissue repair.
2.PRODUCT INDICATIONS
This product is specifically indicated for in vitro laboratory research, preclinical animal model studies, and analytical applications within immunological, microbiological, and dermatological research settings. It serves as a critical reagent for evaluating broad-spectrum antimicrobial potency against multidrug-resistant bacterial pathogens and biofilm-forming strains using standardized MIC and radial diffusion assays, as well as for investigating peptide-lipid membrane interactions via biophysical techniques like NMR and circular dichroism. Researchers utilize CRAMP (mouse) to explore its role in maintaining gut mucosal homeostasis, suppressing intestinal inflammation (such as in DSS-induced colitis models), and regulating the gut microbiota balance in murine systems. Additionally, it is indicated for cell-based assays examining its chemotactic properties, wound-healing potential, and its function as a mechanistic proxy for human LL-37 in studies related to innate immunity, sepsis, chronic inflammatory diseases, and the development of engineered peptide antibiotics.
3.CLINICAL EFFICACY OF PRODUCT
Although CRAMP (mouse) is strictly designated for research use and is not a clinical therapeutic agent, extensive in vitro and murine in vivo studies have demonstrated its significant efficacy in modeling host defense and resolving inflammatory pathologies. Laboratory assays confirm its potent, rapid bactericidal activity against a wide array of clinically relevant pathogens, including Escherichia coli, Pseudomonas aeruginosa, Staphylococcus aureus, and various fungi, often at low micromolar concentrations without facilitating classic resistance development. In murine models of Gram-negative bacterial pneumonia and septic shock, the administration or endogenous expression of CRAMP has proven effective in reducing lung bacterial burdens, lowering endotoxin levels, improving survival rates, and attenuating excessive pro-inflammatory cytokine storms. Furthermore, studies utilizing CRAMP-deficient (Cnlp-/-) mice highlight its crucial efficacy in protecting against DSS-induced ulcerative colitis by supporting colon crypt development, enhancing mucus production, and preventing inflammation-associated carcinogenesis, thereby providing a robust preclinical framework for understanding cathelicidin-based protection in mucosal immunity and tissue homeostasis.
