Abstract: Antimicrobial peptoids with improved selectivity to bacteria and a use thereof are described. Specifically, the antimicrobial peptoids have high antimicrobial activity and greatly decreased toxicity to animal cells. The antimicrobial peptoids show excellent antimicrobial activity against bacteria and exhibit low cytotoxicity to animal cells due to altered degree of folding in helical structure or altered charge characteristics. Therefore, the antimicrobial peptoids have improved selectivity to bacteria, and thus can be usefully used as antimicrobial compositions.

Abstract: The invention relates to the finding that virus like particles (VLPs) can be loaded with immunostimulatory substances, in particular with DNA oligonucleotides containing non-methylated C and G (CpGs). Such CpG-VLPs are dramatically more immunogenic than their CpG-free counterparts and induce enhanced B and T cell responses. The immune response against antigens optionally coupled, fused or attached otherwise to the VLPs is similarly enhanced as the immune response against the VLP itself. In addition, the T cell responses against both the VLPs and antigens are especially directed to the Th1 type. Antigens attached to CpG-loaded VLPs may therefore be ideal vaccines for prophylactic or therapeutic vaccination against allergies, tumors and other self-molecules and chronic viral diseases.

MMP-9 is an extracellular acting endopeptidase implicated in both physiological and pathological processes. A genetically encoded FRET biosensor anchored in the cellular membrane allows studying the proteolytic activity of MMP-9 with high spatiotemporal resolution at the exact region of MMP-9 action on the cell. Applicability of the biosensor, both in vitro and in vivo in living cells, has been demonstrated by ratiometric analysis of cleavage of the biosensor by a purified auto-activating mutant of MMP-9.
