The effects of polypeptide complex from the kidney and short peptides AED, EDL, and AEDG on renal functions were studied in rats with cisplatin-induced acute renal failure. AED peptide decreased protein excretion and electrolyte concentration in the urine. Polypeptide complex from the kidney and peptides EDL and AEDG normalized diuresis, creatinine concentration in the urine and its excretion, glomerular filtration rate, and absolute resorption of sodium ions and reduced protein concentration in the urine and its excretion, the concentrations of sodium and potassium ions in the urine, and other parameters. EDL peptide produced was potent nephroprotective effect. It is known that the polypeptide complex of the kidney and short peptides restore the expression of signal molecules (marker of functional state of the kidneys), so these peptide substances can have nephroprotective effect during various renal pathologies.

Bacterial proteome microarrays are high-throughput, adaptable tools that allow the simultaneous investigation of thousands of proteins from various bacterial species. These arrays are used to explore bacterial pathogenicity, pathogen-host interactions, and clinical diseases. Recent advancements have expanded their application to profiling human antibodies, identifying biomarkers for infectious and autoimmune diseases, and studying antimicrobial peptides (AMPs).

Complex wound closure scenarios necessitate the development of advanced wound dressings that can effectively address the challenges of filling irregularly shaped wounds and managing fatigue failures encountered in daily patient activities. To tackle these issues, we develop a multifunctional hydrogel from natural polysaccharides and polypeptides with injectability and self-healing properties for promoting full-time and multipurpose wound healing. Synthesized through dynamic Schiff base linkages between oxidized hyaluronic acid (OHA), ε-polylysine (ε-PL), and quaternized chitosan (QCS), the OHA/ε-PL/QCS hydrogel can gel rapidly within 50 s.

Ovalbumin (OVA) is a high-risk allergen with complex tertiary structure in food samples. Here, we developed an accurate UPLC-MS/MS-based assay to improve OVA quantitative performance in processed foods. Full-length isotope-labeled OVA proteins (OVA-I) were synthesized using stable isotope labeling by amino acids in cell culture (SILAC) technique and employed as functional internal standards to ensure similar cleavage sites between internal standards and analytes.

Rather than being contained in a single polypeptide, and unlike receptor tyrosine kinases, the T cell receptor (TCR) divides its signaling functions among its subunits: TCRα/β bind the extracellular ligand, an antigenic peptide-MHC complex (pMHC), and the CD3 subunits (CD3γ, CD3δ, CD3ε, and CD3ζ) transmit this information to the cytoplasm. How information about the quality of pMHC binding outside is transmitted to the cytoplasm remains a matter of debate. In this review, we compile data generated using a wide variety of experimental systems indicating that TCR engagement by an appropriate pMHC triggers allosteric changes transmitted from the ligand-binding loops in the TCRα and TCRβ subunits to the cytoplasmic tails of the CD3 subunits.

Short-length peptides are used as therapeutics due to their high target specificity and low toxicity; for example, peptides are designed for targeting the interaction between oncogenic protein p53 and E3 ubiquitin ligase MDM2. These peptide therapeutics form a class of successful inhibitors. To design such peptide-based inhibitors, stapling is one of the methods in which amino acid side chains are stitched together to get conformationally rigid peptides, ensuring effective binding to their partners.
