Our immune system relies on an innate and an adaptive arm that communicate and collaborate to provide us with an optimal response against pathogens. This course focuses on our innate immunity which provides us our first, fast and inherited defence against infections.

What you'll learn
You will identify key innate immunity cells, molecules, and direct defence mechanisms.
You will also learn how our microbiota, the overall micro-organisms found in our body, influences our innate immune response.
Finally, you will understand how our innate immune cells inform our adaptive system of the presence of a threat.

There are 5 modules in this course
In module one, we will explore the main component of the innate immune system. We will start by looking at the surfaces that are first exposed to potential pathogens and how they prevent most pathogens from entering our body. We will then learn about our main innate protective mechanisms and discuss how this inherited system is able to recognise and combat infection. By the end of this module, learners will be able to describe these actors and mechanisms in detail.

In module two, we will explore a key soluble component of our innate immune system: the complement. We will learn about its main components, how it gets activated by pathogens and how the outcome leads to pathogens destruction. We will also explore how the complement system contributes to other innate immune activities, such as phagocytosis, that is the uptake of microorganisms by immune cell for destruction.

In module three, we will investigate how our microbiota plays a protective role in our health. We will first define the human microbiome in more details and explore its influence on various common pathologies such as asthma, diabetes or cancer. The module ends on an opportunity for learners to reflect and share with others on the effects of pro-biotics on our health.

In module four, we will understand how the innate system communicates with the adaptive immune cells. We will explore which cells oversee this essential function and how they capture, digest and present pathogenic molecules to the adaptive immune cells to for their activation. Importantly, we will also investigate how the innate immune response helps this second phase of response to ‘adapt’ to the nature of the infection.

In module five, we will look at one example of innate cells, called Natural Killers, that are directly able to destroy infected and tumour cells. We will explore how they interact with other immune cells, how they recognise their target cells and the mechanisms they use to lead to their death. Importantly, we will also discover the mechanisms that prevent their mis-activation to prevent the disastrous destruction of health host cells.

Frequently asked questions
Access to lectures and assignments depends on your type of enrollment. If you take a course in audit mode, you will be able to see most course materials for free. To access graded assignments and to earn a Certificate, you will need to purchase the Certificate experience, during or after your audit. If you don't see the audit option:
The course may not offer an audit option. You can try a Free Trial instead, or apply for Financial Aid.
The course may offer 'Full Course, No Certificate' instead. This option lets you see all course materials, submit required assessments, and get a final grade. This also means that you will not be able to purchase a Certificate experience.
When you enroll in the course, you get access to all of the courses in the Specialization, and you earn a certificate when you complete the work. Your electronic Certificate will be added to your Accomplishments page - from there, you can print your Certificate or add it to your LinkedIn profile. If you only want to read and view the course content, you can audit the course for free.
If you subscribed, you get a 7-day free trial during which you can cancel at no penalty. After that, we don’t give refunds, but you can cancel your subscription at any time. See our full refund policy.
