CAMP (cathelicidin antimicrobial peptide) recombinant protein is derived from the CAMP gene, which encodes a critical component of the innate immune system in humans and other vertebrates. This gene produces a precursor protein, hCAP18. that is proteolytically cleaved to release the active peptide LL-37. a 37-amino-acid-long cationic antimicrobial peptide. LL-37 exhibits broad-spectrum antimicrobial activity against bacteria, viruses, and fungi, while also modulating immune responses by promoting chemotaxis, wound healing, and cytokine release. Its multifunctional nature makes it a focal point in studying host-pathogen interactions and therapeutic development.
Recombinant CAMP proteins are typically produced using biotechnological platforms, such as Escherichia coli or mammalian expression systems, to ensure high purity and scalability. These systems enable precise control over protein folding and post-translational modifications, critical for maintaining biological activity. The demand for recombinant CAMP arises from challenges in isolating sufficient quantities of natural LL-37 from biological sources and the need for standardized materials for research and clinical applications.
Research on CAMP recombinant protein spans infectious diseases, chronic inflammation, and cancer. It is investigated as a potential antimicrobial agent to combat antibiotic-resistant pathogens, a immunomodulator in autoimmune disorders, and a promoter of epithelial repair in conditions like cystic fibrosis. Additionally, engineered variants of CAMP are being explored to enhance stability, reduce toxicity, or target specific pathogens. Despite its promise, challenges remain in optimizing delivery mechanisms and minimizing off-target effects, underscoring the importance of continued structural and functional studies.
