Abstract
Primitive innate defense mechanisms in the form of gene-encoded antimicrobial peptides are now considered as potential candidates for the development of new therapeutics. They are well known for their function as the first protective barrier of all organisms against microbial infections. In addition, emerging studies reveal that they assist in modulating the host immune system. The biological properties of these host-defense peptides, their role in human health, their cell selectivity and related molecular mechanisms are discussed in this multi-author review along with the strategies to transform them or their peptidomimetics into clinically usable drugs.
