Antimicrobial peptidesastherapeutic agentsclinical applications & challenges Antimicrobial peptides (AMPs) are rapidly gaining recognition as an emerging category of therapeutic agents. These naturally occurring molecules, also known as host defense peptides, are short, generally positively charged peptides found across a wide variety of life formsAn Emerging Category of Therapeutic Agents. Their potent antimicrobial activity and diverse mechanisms of action make them promising candidates for combating infectious diseases, particularly in an era of escalating antibiotic resistance. AMPs represent a multifaceted response to these challenges, offering a potential pathway toward next-generation antibiotics and novel treatments for various conditions.
Antimicrobial peptides are evolutionarily conserved components of the immune system, playing a crucial protective role against a broad spectrum of bacterial and fungal pathogens. They are bioactive macromolecules that exhibit antibacterial, antiviral, and often immunomodulatory functions. Their effectiveness stems from their unique antimicrobial mechanisms, which differ from those of traditional antibiotics and can make it more difficult for microbes to develop resistance.作者：M Mahlapuu·2016·被引用次数：2225—Antimicrobial peptides (AMPs), also known as host defense peptides,are short and generally positively charged peptidesfound in a wide variety of life forms ...
Key characteristics of AMPs include:
* Structure: They are typically short peptides, often cationic and amphiphilic, meaning they have both hydrophilic (water-loving) and hydrophobic (water-repelling) regions. This structure is crucial for their interaction with microbial cell membranes.
* Origin: Found in virtually all organisms, from bacteria and fungi to plants and animals, AMPs are a fundamental part of innate immunity.
* Mechanism of Action: While the exact mechanisms vary, many AMPs target and disrupt the integrity of microbial cell membranes. Some can also penetrate cells to interfere with intracellular processes or modulate the host immune response.
The growing concern over multidrug-resistant pathogens has propelled AMPs into the spotlight as potential alternatives to conventional antibioticsurn:nbn:se:ri:diva-27767 : Antimicrobial peptides. Their broad-spectrum efficacy against a wide range of microorganisms, coupled with a low propensity for resistance development, makes them highly attractive for therapeutic applications.
