MetabolomicsProteolytic-Resistant Self-Assembling Peptide Nanofibers Combat Specific Bacterial Infections via Trap-and-Kill

The rise in global antibiotic resistance highlights the urgent need for effective antimicrobial agents. Antimicrobial peptides (AMPs) offer a potential solution to combat bacterial resistance. However, key challenges remain in addressing the limitations of current peptide drugs and biomaterials, ...

TranscriptomicsThe antimicrobial peptide-sensing system aps of Staphylococcus aureus
Staphylococcus aureus is a leading cause of hospital-associated infections. In addition, highly virulent strains of methicillin-resistant S. aureus (MRSA) are currently spreading outside health care settings. Survival in the human host is largely defined by the ability of S. aureus to resist mechani...

TranscriptomicsQuantitative Different Analysis of antimicrobial peptide LL37 expressed in E.coli Top 10 under aerobic and anaerobic condition.
We reported the transcriptional profiles of E.coli expressing antimicrobial peptide LL37 under stress response condition. 4 samples, two groups, one group is under aerobic condition, the other group is under anaerobic condition. One of samples is E.coli which expressed LL37 as induction in each gro...

ProteomicsProteomic adaptation of Streptococcus pneumoniae to the human antimicrobial peptide LL-37
Secreted antimicrobial peptides (AMPs) are an important part of the human innate immune system and prevent local and systemic infections by inhibiting bacterial growth in a concentration dependent manner. In the respiratory tract, the cationic peptide LL-37 is one of the most abundant AMPs and capab...

TranscriptomicsAnti-microbial peptides increase tolerance to oxidant stress in Drosophila melanogaster
It is well appreciated that reactive oxygen species (ROS) are deleterious to mammals, including humans, especially when generated in abnormally large quantities from cellular metabolism. Whereas the mechanisms leading to the production of ROS are rather well delineated, the mechanisms underlying tis...

ProteomicsIdentification of antimicrobial peptides isolated from the skin mucus of African Catfish, Clarias gariepinus (Burchell, 1822)
Antimicrobial peptides (AMPs) constitute a broad range of bioactive compounds in diverse organisms, including fish. They are effector molecules for the innate immune response, against pathogens, tissue damage and infections. Still, AMPs from African Catfish, Clarias gariepinus skin mucus are largely...

ProteomicsMass spectrometric identification of antimicrobial peptides from medicinal seeds
Traditional medicinal plants contain a variety of bioactive natural products including cysteine-rich (Cys-rich) antimicrobial peptides (AMPs). Cys-rich AMPs are often crosslinked by multiple disulfide bonds which increase their resistance to chemical and enzymatic degradation. However, this class of...

TranscriptomicsA genomic approach highlights common and diverse effects and determinants of susceptibility on the yeast Saccharomyces cerevisiae exposed to distinct antimicrobial peptides
The mechanism of action of antimicrobial peptides (AMPs) was initially correlated with peptide membrane permeation properties. However, recent evidences indicate that action of a number of AMPs is more complex and involves specific interactions at cell envelopes or with intracellular targets. In thi...
