The development of methods able to modulate the binding affinity between proteins and peptides is paramount biotechnological interest in view a vast range applications that imply designed polypeptides capable impair or favour Protein-Protein Interactions. Here, we applied peptide design algorithm based on shape complementarity optimization electrostatic compatibility provided first experimental vitro proof efficacy algorithm. Focusing interaction SARS-CoV-2 Spike Receptor-Binding Domain (RBD) human angiotensin-converting enzyme 2 (ACE2) receptor, extracted 23-residues long structurally mimics major interacting portion ACE2 receptor silico five mutants such with modulated affinity. Remarkably, KD measurements, conducted using biolayer interferometry, matched predictions. Moreover, investigated molecular determinants govern variation through dynamics simulation, by identifying mechanisms driving different values at single residue level. Finally, sequence highest affinity, comparison wild type peptide, was expressed as fusion protein H ferritin (HFt) 24-mer. Solution measurements performed latter constructs confirmed still exhibited expected trend, thereby enhancing their RBD binding. Altogether, these results indicate high potentiality this general method developing potent high-affinity vectors for hindering/enhancing protein-protein associations.

Ferritins are spherical iron storage proteins within cells that composed of a combination 24 subunits two types, heavy-chain ferritin (HFn) and light-chain (LFn). They autoassemble naturally into hollow nanocage with an outer diameter 12 nm interior cavity is 8 in diameter. In recent years, the constantly emerging safety issues concerns about unfavorable uniformity indefinite vivo behavior traditional nanomedicines, characteristics native nanocages, such as unique structure, excellent profile, definite behavior, make ferritin-based formulations uniquely attractive for nanomedicine development. To date, variety cargo molecules, including therapeutic drugs (e.g., cisplatin, carboplatin, paclitaxel, curcumin, atropine, quercetin, gefitinib, daunomycin, epirubicin, doxorubicin, etc.), imaging agents fluorescence dyes, radioisotopes, MRI contrast agents), nucleic acids siRNA miRNA), metal nanoparticles Fe3O4, CeO2, AuPd, CuS, CoPt, FeCo, Ag, etc.) have been loaded nanocages broad range biomedical applications from vitro biosensing to targeted delivery molecules living systems aid modified targeting ligands either genetically or chemically.

Proteins and enzymes are versatile biomaterials for a wide range of medical applications due to their high specificity receptors substrates, degradability, low toxicity, overall good biocompatibility. Protein nanoparticles formed by the arrangement several native or modified proteins into nanometer-sized assemblies. In this review, we will focus on artificial nanoparticle systems, where main structural element not just an encapsulated payload. While under natural conditions, only certain form defined aggregates nanoparticles, chemical modifications change in physical environment can further extend pool available building blocks. This allows assembly many globular even enzymes. These advances preparation methods led emergence new generations nanosystems that beyond transport vehicles diverse applications, from multifunctional drug delivery imaging, nanocatalysis protein therapy.

Nanocarrier drug delivery systems (NDDS) have gained momentum in the field of anticancer or nucleic acid due to their capacity aggrandize targeting efficacy and therapeutic outcomes encapsulated drugs. A disadvantage NDDS is that repeated administrations often encounter an obstacle known as "accelerated blood clearance (ABC) phenomenon". This phenomenon results rapid secondary dose from bloodstream markedly augmented liver accumulation, which substantially undermines accurate drugs effect NDDS. Nevertheless, underlying mechanism this has not been elucidated there currently no effective method for its eradication. In light above, aim review provide a comprehensive summary potential countermeasures ABC phenomenon, with view rejuvenating both slow-release property expectation clinic. paper, we innovatively introduce pharmacokinetic further elucidate occurrence after discussing immunological mechanism, provides new direction expanding mechanistic study phenomenon.
