Natural polymer is biocompatible and biodegradable, which enables safety, improves storage, and physiological stability, it is utilized as drug delivery vehicles and has made great strides in recent years. Chitosan, alginate, pectin, guar gum, dextran, hyaluronic acid, and arabinoxylan are examples of natural polysaccharides that are utilized to create nanoparticles. Natural gums serve two purposes: first, they shield the medicine from stomach and intestinal conditions, allowing it to only be released in the colon.

Using mAbs, researchers can identify and target specific molecules in the body involved in the disease process. This has allowed for a more targeted treatment approach, which has resulted in improved outcomes for many patients. This hypothesis has been the basis for the development of mAbs that can target an array of illnesses. In the past two decades, therapeutic mAbs have been developed to treat cancer, autoimmune diseases, cardiovascular diseases, and metabolic diseases. For instance, using mAbs has improved outcomes in treating rheumatoid arthritis, multiple sclerosis, and Crohn's disease. However, delivering mAbs in biological systems remains a significant challenge in drug delivery. This is due to their large size, low stability in circulation, and difficulties in achieving their desired action in the target cells. Monoclonal antibodies (mAbs) are an essential tool in biological systems, as they can be used to deliver drugs to specific cell types or tissues. Cloning methods of monoclonal antibody production have been developed to produce mAbs with therapeutic potential. Hence, the present review focused on the development and drug delivery of Monoclonal antibodies (mAbs) in biological systems, which includes cloning methods, various drug delivery technologies, formulation production technology, and its applications in multiple diseases were focused for this review.</p>","PeriodicalId":94352,"journal":{"name":"Recent advances in drug delivery and formulation","volume":" ","pages":"264-285"},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"71430782","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
