Summary
Structure- or size-transformable peptide-based antibacterial biomaterials (SSTPABs) offer a promising alternative to traditional antibiotics. These adaptable biomaterials can be engineered to respond to infection environments, enhancing treatment efficacy and overcoming current limitations.
Area of Science:
- Biomaterials Science
- Infectious Diseases
- Nanotechnology
Background:
- Traditional antibiotics face challenges like side effects, poor targeting, and resistance.
- There is an urgent need for novel strategies to combat bacterial infections.
- Structure- or size-transformable peptide-based antibacterial biomaterials (SSTPABs) are emerging as a potential solution.
Purpose of the Study:
- To review various types of SSTPABs and their design strategies.
- To elaborate on the key functions of SSTPABs in bacterial infection treatment.
- To discuss challenges and future directions for SSTPABs in clinical translation.
Main Methods:
- Comprehensive literature review of SSTPABs from 2020 to present.
- Analysis of SSTPAB transformation mechanisms (monomer-nanostructure, nanostructure-nanostructure).
- Examination of design strategies and functional applications in infection models.
Main Results:
- SSTPABs can transform between monomers and various nanostructures (nanoparticles, nanofibers, nanosheets, nanorods).
- Key functions include enhanced biofilm penetration, improved site accumulation, controlled drug release, and bacteria-specific capture.
- Design strategies leverage responsiveness to microenvironment stimuli (pH, enzymes, ROS) and external triggers (light, ultrasound).
Conclusions:
- SSTPABs offer versatile properties through tunable size and structure transformations.
- Their ability to respond to stimuli and perform specific functions shows great potential for infection treatment.
- Addressing clinical translation challenges is crucial for advancing SSTPABs in animal husbandry, materials science, and biomedicine.

13.0K
Antimicrobial proteins are important components of the immune system. They aid the body in combating pathogens by either killing them directly or hindering their replication processes. Four main types of antimicrobial substances are interferons, the complement system, iron-binding proteins, and antimicrobial proteins.
Interferons
Interferons (IFNs) are proteins produced by lymphocytes, macrophages, and fibroblasts infected with viruses. While IFNs cannot prevent viruses from entering and...

01:30Bacterial Signaling
40.1K
Bacterial signaling can occur within bacteria (intracellular) or between bacteria (intercellular). At times, a group of bacteria behaves like a community. To achieve this, they engage in quorum sensing, the perception of higher cell density that causes changes in gene expression. Quorum sensing involves both extracellular and intracellular signaling. The signaling cascade starts with a molecule called an autoinducer (AI). Individual bacteria produce AIs that move out of the bacterial cell...
