课程概况

This course aims to provide current understanding about extracellular vesicles (EVs) and their role in health and diseases. The EVs are known to be involved in cell to cell communication. Apart from maintaining normal cell physiology, EVs deliver messages that can drive or influence the progression of a disease. This course discusses recent advances made in the field to give an introduction on their function in health as well as in disease.This course includes four modules. Module 1 is an introduction to the course, and provides an overview of the previous MOOC on EVs “Basics of Extracellular Vesicles”. Module 2 focuses on the role of EVs in physiological conditions and gives various examples on their role in metabolism, inflammation, immunity and pregnancy and coagulation. This module also briefly covers the topic of microorganism-derived EVs such as vesicles from bacteria and discusses EVs from apoptotic and senescent cells. In Module 3, we focus on the role of EVs in cancer: how EVs can mediate communication between the tumour and its microenvironment, the functional role of immune cell-derived EVs in development of cancer, as well as the role of EVs in cancer cell proliferation, survival, metastasis and drug resistance. In Module 4, the role of EVs in diseases of the cardiovascular, haematopoietic, nervous, respiratory and urinary systems, and infectious diseases will be presented.This course is recommended for intermediate learners or anyone who is interested in the field of extracellular vesicles and their role in a particular disease including scientists, clinicians, or cell and molecular biologists who look to broaden their understanding of the field.

课程大纲

Physiological Function of EVs

In this module, we will discuss the role of extracellular vesicles in maintaining cellular homeostasis, why they are important for this process. How microorganism such as in gram positive and negative bacteria can secrete EVs, will be discussed. Altered EV secretion as a response to inflammation, stress and apoptosis or senescence will be highlighted. Furthermore, some examples will be provided on how EV cargo can influence cellular metabolism and the function of EVs in maintaining physiology of cells in pregnancy and coagulation.

Pathophysiology of EVs in Cancer

This module will highlight the role of EVs in the progression of cancer and how the cargo delivered via EVs can directly influence cancer cell proliferation or metastatic properties. The communication between tumour and immune cells, stromal, and endothelial cells will be discussed. We will cover some of the considerations and guidelines that are important in utilising EVs as cancer biomarkers. Techniques that are commonly used to detect EVs, selection of biofluid for tumour EV biomarker analysis, model used in studying EVs, selection of specific EV cargo as biomarker and examples for studies on EVs as cancer biomarkers will be highlighted.

Pathophysiology of EVs in Various Diseases

We will discuss the reported role of EVs in mediating the development of various diseases such as cardiovascular diseases, hematological disorders, neurological diseases, urological, respiratory diseases and infectious diseases. This module will also highlight some of the proposed EV associated biomarkers and some therapeutic strategies by utilizing EVs to deliver inhibitory molecule.
