From Innate Immunity to Therapeutic Potential: Evaluating Recombinant LL-37 Against Resistant Pathogens

The rapid escalation of antimicrobial resistance (AMR) continues to undermine the effectiveness of conventional antibiotics, particularly against pathogens belonging to the ESKAPE group. Despite decades of antibiotic discovery, the clinical pipeline for new antibacterial agents remains limited, while resistance mechanisms evolve at an accelerat…

Engineering Esc(1-21): Isopeptide Bond Positioning for Optimized Antimicrobial Performance

Antimicrobial peptides (AMPs) are promising candidates for combating multidrug-resistant pathogens, yet their therapeutic potential is often limited by host cytotoxicity and proteolytic instability. This study focuses on Esculentin-1a(1–21)NH₂ [Esc(1-21)], a frog-skin–derived AMP with potent Gram-negative activity, and explores a novel optimiza…

Peptide Cancer Vaccines Revisited: Overcoming Biological Limitations Through Rational Design

Peptide-based cancer vaccines were once regarded as a promising yet ultimately unsuccessful immunotherapeutic strategy, largely due to limited clinical efficacy in early trials. However, these outcomes reflected fundamental biological and design limitations rather than intrinsic shortcomings of peptide antigens. Advances in cancer immunology ha…

Latex-Derived Peptides and Enzymes: Nature’s Answer to Antibiotic Resistance

The rapid rise of antimicrobial resistance has intensified the global search for alternatives to conventional antibiotics. Among the most promising candidates are antimicrobial peptides (AMPs), naturally occurring molecules with broad-spectrum activity and unique mechanisms that limit resistance development. Recent research highlights latex fro…
