Abstract:

The increasing costs of treatment of chronic wounds has urged the scientific community to look for more efficient wound-dressings. When addressing a chronic wound one should consider the diverse microbial environment that needs to be targeted, but also supporting wound healing. Biocompatible materials support the healing of the wound while antimicrobial agents (i.e., iodine, honey and silver, etc) can be easily incorporated if needed. Due to the rise of antibiotic resistance treatment of chronic wounds has become extremely complicated because of the lack of adequate dressing systems. Recently there is a growing interest towards the use of natural products with antimicrobial features, such as antimicrobial peptides (AMPs). Therefore, we plan to design AuBPs-based flexible PDMS patches functionalized with antimicrobial peptides used as a new alternative for chronic wounds treatment. We plan to combine the effect of photo-thermal disinfection generated by gold nanobipyramids activated with white light (e.g. smartphone torch light) with the one obtained by AMP release. To our knowledge, this is the first study that envisages flexible wound dressing with synergistic photo-thermal and antimicrobial capabilities.

Abstract:

Antimicrobial peptides are a type of host defense peptides that present both high therapeutic potential and high selectivity of interaction with bacterial cells over mammalian cells. However, the possibility of bacterial resistance occurring against natural AMPs activity, combined with the already picked low-hanging fruits of obvious natural peptide targets, suggests the need for novel AMP design approaches. The main challenge is increasing efficacy of the novel drugs in safety conditions, since previous individual design methods had only limited success thus far.

The main objective of this application is the development of a new approach on identifying potential novel antimicrobial drugs. The ground-breaking nature of the proposed approach is that it combines the predicting power of several complementary computer-aided design methods with experimental validation of the proposed AMPs. We will computationally design new AMPs whose purpose would be to disrupt or pass through membrane models, and experimentally validate their efficiency against several bacterial strains. This new approach, can, in principle, be applied to find novel AMPs and rank them by their computationally predicted relative antimicrobial activity and cytotoxicity.

Abstract:

Ras proteins mediate a wide variety of signal transduction pathways that regulate cell growth,proliferation and differentiation.These proteins are small GTPases acting as binary switches between the GDP-bound “off” and the GTP-bound “on” states.Oncogenic mutations of Ras renders them constitutively active and are associated with ~15% of all human cancers and up to 90% in specific tumors.Current strategies for developing drugs targeting Ras mutants had little success.Experiments and computer simulations alike showed that membrane-bound Ras proteins form nonoverlapping dynamic nano-sized subdomains (nanoclusters) in an activation state-/isoform-dependent manner.Nanoclusters are protein-lipid assemblies serving as exclusive sites for effector recruiting and signal activation.The main objective of this application is the development of a new approach on finding potential drugs against oncogene Ras.The ground-breaking nature of this approach is that it exploits the dynamic nature of Ras nanoclusters and the key role of their stability in signal transduction.We will computationally determine Ras self-association binding sites and their binding strengths.The results will be used to design new lipid-modified peptides(LMPs) which,due to their designed features,would disrupt Ras nanoclusters.Since Ras nanoclusters are highly dynamic in nature,the peptide-Ras interaction should disrupt nanocluster’s stability and hence the signal output.

Abstract:

Development of nanostructures capable of detecting and separating individual molecules and ions has become an important field of research. Particularly, protein-based nanostructures are attractive due to their ability for tunable molecular recognition and ease of chemical modification, which are extremely important factors on various applications. In this project, self-assembly functionalization will be approached, aimed at providing an efficient design for molecular recognition, ion sensing and separation, through new host-guest chemical methodologies, bio-nanofabrication and physicochemical manipulations methods. New crown ether type macrocycles, functionalized cyclodextrins and cyclic peptides will be engineered to work as specific molecular adaptors for the -hemolysin protein, giving rise to hybrid molecular superstructures possessing ion sensing and selectivity properties. The size and functionality of the macrocycles are targeted to ensure the anchorage in the pores and the selectivity of specific host-guest complexation processes. A surface detector array device suitable for use with a biosensor is envisioned, through ink printing nanotechnologies. The device architecture will be formed of a substrate having a surface defining a plurality of distinct bilayer-compatible surface regions separated by one or more bilayer barrier regions. Custom designed nanoscale bilayers containing selected receptors through cyclodextrins derivatives and macrocyclic peptides, self-assembled on different micro-nano arrays surfaces (polymers, Au or Si) will be fabricated. Further engineering of such functionalized nanomaterials based on molecular recognition and host-guest methodologies, in conjunction with flexible and mechanically robust enough substrate platforms, have the great potential for applications such as separation of nanoparticles, sensors, drug delivery, removal of heavy metals from aqueous solutions and chiral separation.
