Special Issue Information

Dear Colleagues,

The last two decades have witnessed great achievements in the design and self-assembly of peptides to generate functional materials. Peptides, as the molecular building blocks, can be either de novo designed or engineered, based on naturally derived sequences that self-assemble into highly ordered nanostructures and nanostructured networks. From a fundamental viewpoint, the self-assembly strategy, in combination with new peptide design principles and chemistry has provided powerful tools to fabricate a wide range of thermodynamically stable and kinetically trapped nanostructures, as well as dynamic and smart nanostructures and materials in response to specific triggers. Comprehensive structural characterization of these hierarchical structures and fundamental analysis and understanding of their thermodynamics and kinetics are crucial to develop self-assembled, well-regulatedpeptides. From the viewpoint of practical applications, the main focus is to develop optimal functionality of self-assembled peptides. Pre-functionalization of the molecular building blocks and post-modification of the self-assembly are both effective methods to endow functions on self-assembled peptides and both are being extensively explored with regard to a variety of nanotechnological and biotechnological applications.

The main aim of this Special Issue is to create an open forum where researchers can share their new methods, results, perspectives and insights, and work together to address emerging issues of both fundamental and practical significance in peptide self-assembly. Contributions to this issue, both in the form of original research or review articles, may cover all aspects of peptide self-assembly and multidisplinnary studies offering new principles, methodologies/strategies and insights are particularly welcome.

Peptide amphiphile micelles (PAMs) are a nanoparticle platform that have gained popularity for their targeting versatility in a wide range of disease models. An important aspect of micelle design is considering the type of hydrophobic moiety used to synthesize the PAM, which can act as a contributing factor regarding their morphology and targeting capabilities. To delineate and compare the characteristics of spherical and cylindrical micelles, we incorporated the monocyte-targeting chemokine, monocyte chemoattractant protein-1 (MCP-1), into our micelles (MCP-1 PAMs). We report that both shapes of nanoparticles were biocompatible with monocytes and enhanced the secondary structure of the MCP-1 peptide, thereby improving the ability of the micelles to mimic the native MCP-1 protein structure. As a result, both shapes of MCP-1 PAMs effectively targeted monocytes in an in vitro binding assay with murine monocytes. Interestingly, cylindrical PAMs showed a greater ability to attract monocytes compared to spherical PAMs in a chemotaxis assay. However, the surface area, the multivalent display of peptides, and the zeta potential of PAMs may also influence their biomimetic properties. Herein, we introduce variations in the methods of PAM synthesis and discuss the differences in PAM characteristics that can impact the recruitment of monocytes, a process associated with disease and cancer progression.

Abstract: Fused in sarcoma (FUS) is a DNA / RNA binding protein, which is involved in RNA metabolism and DNA repair. Numerous reports have demonstrated that FUS is associated with a variety of neurodegenerative diseases by pathological and genetic analysis, including amyotrophic lateral sclerosis(ALS), frontotemporal lobar degeneration (FTLD) and polyglutamine diseases. Traditionally it was considered that the fabric aggregation of FUS caused those diseases, especially via its prion-like domains(PrLDs), rich in glutamine and asparagine resides. Lately, a non-fabric self-assembling phenomenon, liquid-liquid phase separation (LLPS) was observed in FUS and the studies of its functions, mechanism and mutual transformation with pathogenic amyloid were emerging. This review summarizes recent studies on FUS self-assembling, including both aggregation and LLPS, and their relationship with the pathology of ALS, FTLD and other neurodegenerative diseases.
