Abstract
Peptide self-assembly, due to its diverse supramolecular nanostructures, excellent biocompatibility, and bright application prospects, has received wide interest from researchers in the fields of biomedicine and green life technology and the food industry. Driven by thermodynamics and regulated by dynamics, peptides spontaneously assemble into supramolecular structures with different functional properties. According to the functional properties derived from peptide self-assembly, applications and development directions in foods can be found and explored. Therefore, in this review, the regulatory mechanism is elucidated from the perspective of self-assembly thermodynamics and dynamics, and the functional properties and application progress of peptide self-assembly in foods are summarized, with a view to more adaptive application scenarios of peptide self-assembly in the food industry.

Abstract
The understanding on how short peptide assemblies transit from disorder to order remains limited due to the lack of atomistic structures. Here we report cryo-EM structure of the nanofibers short intrinsically disordered peptides (IDPs). Upon lowering pH or adding calcium ions, the IDP transitions from individual nanoparticles to nanofibers containing an aromatic core and a disordered periphery comprised of 2 to 5 amino acids. Protonating the phosphate or adding more metal ions further assembles the nanofibers into filament bundles. The assemblies of the IDP analogs with controlled chemistry, such as phosphorylation site, hydrophobic interactions, and sequences indicate that metal ions interact with the flexible periphery of the nanoparticles of the IDPs to form fibrils and enhance the interfibrillar interactions to form filament bundles. Illustrating that an IDP self-assembles from disorder to order, this work offers atomistic molecular insights to understand assemblies of short peptides driven by noncovalent interactions.

Abstract
Selectively targeting the membrane-perturbing potential of peptides towards a distinct cellular phenotype allows one to target distinct populations of cells. We report the de novo design of a new class of peptide whose ability to perturb cellular membranes is coupled to an enzyme-mediated shift in the folding potential of the peptide into its bioactive conformation. Cells rich in negatively charged surface components that also highly express alkaline phosphatase, for example many cancers, are susceptible to the action of the peptide. The unfolded, inactive peptide is dephosphorylated, shifting its conformational bias towards cell-surface-induced folding to form a facially amphiphilic membrane-active conformer. The fate of the peptide can be further tuned by peptide concentration to affect either lytic or cell-penetrating properties, which are useful for selective drug delivery. This is a new design strategy to afford peptides that are selective in their membrane-perturbing activity.

Abstract
Endosome/lysosome, as the potential risk of therapeutic inactivation resulting from physical obstruction and a number of acid hydrolases, is a bottleneck in effective intracellular delivery which needs to be overcome. One promising strategy to avoid this barrier is to deliver therapeutic agents directly into the cytoplasm. In this study, CLIP6 peptide (KVRVRVRVDPPTRVRERVK-NH2) which can facilitate non-endosomal cell entry and anticancer drug doxorubicin (DOX) were covalently grafted to N-(2-hydroxypropyl)methacrylamide (HPMA) backbone (P-DOX-CLIP6). As a result, CLIP6 peptide modification increased the cellular uptake of DOX-loaded HPMA copolymers. Importantly, it effectively reduced lysosomal accumulation, leading to stronger proliferation inhibition and superior growth inhibition effect on three-dimensional tumor spheroids, compared to unmodified HPMA copolymer conjugates. Furthermore, P-CLIP6-DOX induced the highest therapeutic efficacy in HeLa tumor-bearing nude mice. Meanwhile, no significant systemic toxicity was observed during the treatment. In conclusion, this study provided a promising strategy to efficiently deliver drug candidates which were limited by endo/lysosomal trapping.

Abstract
The internalisation and delivery of active substances into cells is a field of growing interest for chemical biology and therapeutics. As we move from small-molecule-based drugs towards bigger cargos, such as antibodies, enzymes, nucleases or nucleic acids, the development of efficient delivery systems becomes critical for their practical application. Different strategies and synthetic carriers have been developed; these include cationic lipids, gold nanoparticles, polymers, cell-penetrating peptides (CPPs), protein surface modification etc. However, all of these methodologies still present limitations relating to the precise targeting of the different intracellular compartments and, in particular, difficulties in access to the cellular cytosol. Additionally, the precise quantification of the cellular uptake of a compound is not enough to demonstrate delivery and/or functional activity. Therefore, methods to determine cellular distributions of cargos and carriers are of critical importance for identifying the barriers that are blocking the activity. Herein we survey the different techniques that can currently be used to track and to monitor the subcellular localisation of the synthetic compounds that we deliver inside cells.
