Background:

Defensins are cationic antibiotic peptides characterized by six cysteines in disulfide linkage.
These peptides are abundant in mammalian phagocytes and intestinal mucosa, as well as insect hemolymph.

Purpose of the Study:

To review the role of defensins in host defense mechanisms.
To explore the potential of bioengineered defensins in combating infections.

Main Methods:

Literature review of defensin structure and function.
Analysis of defensin involvement in inflammation and endocrine regulation.
Evaluation of bioengineered defensin applications.

Main Results:

Defensins play a significant role in host defense against microbial pathogens.
