HMX Immunology

Get an in-depth look at how the body fights disease – and how new therapies can help.


Microbial life forms are an ever-present, extremely dangerous threat to our survival, against which the immune system must constantly defend.

In HMX Immunology, you’ll learn about the processes that enable our immune systems to respond to evolving threats, and learn about new, immunology-based disease treatments.

Why do you think it’s important for aspiring health care professionals to learn immunology?

Over the past several decades, there has been an enormous increase in the scientific evidence for a central role of the immune system in a wide range of common human diseases, including those that cause the most morbidity and mortality worldwide. Many of these disorders had traditionally not been viewed through the immunology lens, such as cancer and cardiovascular disease, but that is all changing now.  Therefore, a basic understanding of the components, functions, and mechanisms of the immune system is really an essential foundation for anyone planning to train for a career in healthcare.

What do you want students to take away from this course?

On completion of the course, students should understand the fundamental ways the immune system protects us, and appreciate how deficiencies, excesses, or mistargeting of immune responses contribute to disease. Furthermore, students should be aware of the many ways the science of immunology has already been successfully translated into clinical medicine. The basic knowledge gained from this course should facilitate students’ continued course-based and self-learning of immunology.

Why do you think it’s important for aspiring health care professionals to learn immunology?

The immune system protects us from infections and cancer in a very exquisitely precise way. Most human diseases result from some loss of this precision. Sometimes the immune system is overwhelmed by an infection or a tumor. On other occasions the immune system aberrantly or over-exuberantly responds to innocuous environmental molecules or microbes – or to self-structures – and this results in a loss of immune regulation that results in disease. Understanding immunology has allowed the prevention of infections by the use of vaccines, has helped the medical world develop the ability to transfuse blood making modern surgery possible, has allowed transplantation to become a reality, and has led to rational treatments for allergies and autoimmune diseases, and what are likely the first real cures for cancer. Many of the therapies of the future will likely be derived from an even better understanding of immunology and how the loss of immune regulation leads to specific diseases. No other field of basic science is so intimately connected to the pathogenesis of disease or to treatment.

What do you want students to take away from this course?

Students should understand the underlying concepts of how the immune system works and how knowledge of immunology has already impacted the understanding and treatment of a range of human disorders.
