Abstract:
This review aims to systematically synthesize recent research advances on the antimicrobial peptides (AMPs) derived from the black soldier fly (Hermetia illucens). Against the backdrop of the escalating global crisis of antimicrobial resistance (AMR), AMPs have emerged as pivotal candidates to replace conventional antibiotics. As a unique saprophagous insect, H. illucens has evolved a robust and efficient innate immune system to thrive in its pathogen-rich environment. The AMPs it produces demonstrate remarkable broad-spectrum activity, high stability, and a low propensity for inducing resistance. Based on cutting-edge research available up to 2025, this article will provide an in-depth exploration of the astounding molecular diversity of H. illucens AMPs, their key structure-function relationships, and their multifaceted mechanisms of action, ranging from membrane disruption to immunomodulation. It will also highlight engineering strategies driven by artificial intelligence (AI). Finally, the review will assess the significant translational potential of these AMPs in combating multidrug-resistant bacteria, analyzing the current status of research in animal models, the challenges for industrial production, and viable future development pathways. The goal is to provide a solid theoretical foundation and forward-looking perspective to facilitate the translation of this valuable biological resource from basic research to clinical and agricultural applications.

01:23Propagation of Action Potentials
Neurons (nerve cells) have a resting membrane potential, with a slightly negative charge inside compared to outside. This is maintained by ion channels, such as sodium (Na+) and potassium (K+) channels, which control the flow of ions. When a stimulus, like a touch or a signal from another neuron, triggers the neuron, sodium channels open, allowing sodium ions to...
