A rapid absorption and retention of antimicrobial peptides by dead Escherichia coli cells can increase the survivability of the cell population in a "cooperative" fashion.
Inhibition of bacterial protein synthesis by an antimicrobial peptide apidaecin triggers translation arrest at the stop codons, ribosome queuing and pervasive stop codon readthrough.
The attempt to manipulate a microbiome in planta to study the ecological consequences under field conditions leaves plants and their microbes surprisingly unimpressed.
While antimicrobial cocktails are highly effective for defence against pathogenic microbes, the innate immune response may instead employ highly specific peptidic antibiotics to combat certain natural enemies.
Proline/glycine kink in the helical peptides affects the peptide ability to form membrane pores by stabilising toroidal pore structures but disrupting barrel-stave pore structures.
A novel innate defense mechanism of cell lysis involves the coordinated oligomerization of a defensin by interaction with the membrane lipid, phosphatidylinositol 4,5-bisphosphate.
Targeting the differentiation regulators and/or AMPs of keratinocytes, rather than targeting immune cells, may be an alternative approach for topical anti-psoriatic treatment, an area with high need for new drugs.
The immune effector Drosomycin buffers stress signaling in hypertrophic salivary glands to inhibit their disintegration, detection by the cellular immune response, and promotes further overgrowth.
