Learn about your body's defenses against disease: how it can identify threats and coordinate counterattacks.
When you're sick, you may wonder, "Why me?" But the real question should be, "Why am I not sick all the time?" You might even ask, "Why does my body respond with a fever, and is it really a good idea to lower it?" This course explores immunology, how the body defends itself from constant assault by parasites and pathogens. This course will present the fundamentals of both innate and adaptive immunity, emphasizing functional interactions among cells and organs. We will cover signaling, pathogen recognition and the division of labor among myeloid, lymphoid and supporting cells. The subject matter will also supply health professionals and biomedical researchers with the basic vocabulary and concepts necessary to understand both clinical press releases and primary literature. The course materials also provide support to other immunology instructors by presenting difficult concepts in creative ways using analogies and models.
What you'll learn:
- The importance of disease defense
- The difference between innate and adaptive immunity
This course introduces learners to a variety of infectious diseases using a patient-centered, story-based approach. Through illustrated, short videos, learners will follow the course of each patient’s illness, from initial presentation to resolution. Integrating the relevant microbiology, pathophysiology and immunology, this course aims to engage and entice the learner towards future studies in microbiology, immunology and infectious diseases.
More than a century ago, Elie Metchnikoff established the bases of cellular innate immunity when he discovered the mechanism of phagocytosis. However, during most of the XXth century, adaptive immunity (also known as specific immunity) focused most of the interest of the researchers, until Charles Janeway and Polly Matzinger revisited the definition of immunology. What was called “non-specific immunity” was renamed “innate immunity”, and the understanding of the sensing of the exogenous or endogenous dangers signals, and their identification revolutionized our understanding of the early mechanism aimed to defend the integrity of the host against any type of attacks including pathogens.
MOOCs – Massive Open Online Courses – enable students around the world to take university courses online. This guide, by the instructors of edX’s most successful MOOC in 2013-2014, Principles of Written English (based on both enrollments and rate of completion), advises current and future students how to get the most out of their online study, covering areas such as what types of courses are offered and who offers them, what resources students need, how to register, how to work effectively with other students, how to interact with professors and staff, and how to handle assignments. This second edition offers a new chapter on how to stay motivated. This book is suitable for both native and non-native speakers of English, and is applicable to MOOC classes on any subject (and indeed, for just about any type of online study).
