Abstract:

Exosome is a nanoscale extracellular vesicle produced by fusion of intracellular multivesicular bodies with cell membranes.They are widely distributed in serum,urine,saliva and other biological fluids.As an important transfer vector for intercellular communication and genetic material,exosomes can directly stimulate target cells through receptor-mediated interactions or through the transfer of various biologically active molecules such as cell membrane receptors,proteins,mRNAs and miRNAs,thereby exerts its biological functions.The article mainly reviews the functions of proteins and miRNAs in exosomes and the clinical application of exosomes.The functions of proteins and miRNAs in exosomes include inducing immunity,presenting antigens,and participating in intercellular signaling under physiological conditions;Changing the tumor microenvironment under pathological conditions,promoting cancer cell proliferation,invasion,accelerating angiogenesis,and promoting cancer development;Certain viruses can package and integrate their components into exosomes to achieve intercellular transmission,or hijack exosomes for immune evasion.Exosome in the clinical should mainly introduce its biological markers for early diagnosis of various cancers such as lung cancer,breast cancer,pancreatic cancer and colorectal cancer,as well as high stability,high transport efficiency and strong targeting drug carrier is used for treatment.

Key words: exosome; protein; miRNA; disease diagnosis; drug carrier
