Abstract
Pancreatic ductal adenocarcinoma (PDAC) is an aggressive malignancy characterized by a dense extracellular matrix (ECM) and a uniquely immunosuppressive tumor microenvironment (TME), which together form a formidable barrier that hinders deep drug penetration, limiting the efficacy of conventional therapies and leading to poor patient outcomes. Nanocarrier technology emerges as a promising strategy to improve treatment efficacy in PDAC. Nanocarriers can not only improve drug penetration through their adjustable physicochemical properties but also effectively regulate immune cell function in pancreatic cancer TME and promote anti-tumor immune response. This mini-review discusses the effects of nanocarriers on the immune microenvironment of PDAC, analyzing their mechanisms in modulating immune cells, overcoming ECM barriers, and reshaping the TME.
期刊介绍：
Essays in Biochemistry publishes short, digestible reviews from experts highlighting recent key topics in biochemistry and the molecular biosciences. Written to be accessible for those not yet immersed in the subject, each article is an up-to-date, self-contained summary of the topic.
Bridging the gap between the latest research and established textbooks, Essays in Biochemistry will tell you what you need to know to begin exploring the field, as each article includes the top take-home messages as summary points.
Each issue of the journal is guest edited by a key opinion leader in the area, and whether you are continuing your studies or moving into a new research area, the Journal gives a complete picture in one place.
Essays in Biochemistry is proud to publish Understanding Biochemistry, an essential online resource for post-16 students, teachers and undergraduates. Providing up-to-date overviews of key concepts in biochemistry and the molecular biosciences, the Understanding Biochemistry issues of Essays in Biochemistry are published annually in October.
