Recent observations have suggested that SARS-CoV-2 damages the central nervous system of patients in a manner similar to amyloid-associated neurodegenerative diseases such as Alzheimer's and Parkinson's. Neurodegenerative diseases are believed to be associated with the self-assembly of amyloid proteins and peptides. On the other hand, whole proteins or parts of them encoded by SARS-CoV-2 can form amyloid fibrils, which may play an important role in amyloid-related diseases. Motivated by this evidence, this mini-review discusses experimental and computational studies of SARS-CoV-2 proteins that can form amyloid aggregates. Liquid-Liquid Phase Separation (LLPS) is a dynamic and reversible process leading to the creation of membrane-less organelles within the cytoplasm, which is not bound by a membrane that concentrates specific types of biomolecules. These organelles play pivotal roles in cellular signaling, stress response, and the regulation of biomolecular condensates. Recently, LLPS of the Nucleocapsid (N) protein and SARS-CoV-2 RNA has been disclosed, but many questions about the phase separation mechanism and the formation of the virion core are still unclear. We summarize the results of this phenomenon and suggest potentially intriguing issues for future research.</p>","PeriodicalId":10859,"journal":{"name":"Current protein & peptide science","volume":" ","pages":""},"PeriodicalIF":1.9,"publicationDate":"2025-05-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143967691","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Given the importance of COVID-19 worldwide, since its spread, many research groups have been seeking blood markers that could help to understand the disease establishment and prognosis. Usually, those markers are proteins with a differential accumulation only during infection. Based on that, proteomic studies have played a crucial role in elucidating diseases. Mass spectrometry (MS) is a promising technique in COVID-19 studies, allowing the identification and quantification of proteins present in the plasma or serum of affected patients. It helps us to understand pathological mechanisms, predict clinical outcomes, and develop specific therapies. MS proteomics revealed biomarkers associated with infection, disease severity, and immune response. Plasma or blood serum is easy to collect and store; however, its composition and the higher concentration of proteins (e.g., albumins) shadow the identification of less abundant proteins, which usually are essential markers. So, clean-up approaches such as depletion strategies and fractionating are often required to analyze blood samples, allowing the identification of low-abundant proteins. This review will discuss many proteomic approaches to discovering new plasma biomarkers of COVID-19 employed in recently published studies. The challenges inherent to blood samples will also be discussed, such as sample preparation, data processing, and identifying reliable biomarkers.</p>","PeriodicalId":10859,"journal":{"name":"Current protein & peptide science","volume":" ","pages":""},"PeriodicalIF":1.9,"publicationDate":"2025-05-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143978498","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It is derived from a specific allelic composition on chromosome 6. The only difference between A1 and A2 milk results from the polymorphism at the 67 amino acid chain. In this position, A2 milk has a proline amino acid, while A1 milk has a histidine amino acid. Proteins are one of the most important components of milk, especially casein, and have received significant attention as they are the source of bioactive opioid peptides called beta-casomorphin-7. Peptides are released through enzymatic digestion of casein and whey proteins. More precisely, this bioactive peptide is produced by sequential gastrointestinal digestion of bovine A1 variants proteins, while this phenomenon is not present in variant A2. Studies have reported that A1 milk can be harmful to health not only for adults but also for infants and that β-casein A2 becomes a safer choice following the relationship between disease risk and consumption of the beta-casomorphin-7 peptide. Indeed, epidemiological studies suggest that the released beta-casomorphin-7 peptide is a risk factor for the development of diseases in humans, but this has not yet been validated by other studies. In contrast, A2 milk has been suggested as an appropriate substitute for A1 milk since populations consuming milk containing high levels of the A2 beta-casein variant have lower rates of diseases, such as diabetes, coronary heart disease, autism, and schizophrenia.</p>","PeriodicalId":10859,"journal":{"name":"Current protein & peptide science","volume":" ","pages":""},"PeriodicalIF":1.9,"publicationDate":"2025-04-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143985030","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
