Immunology: Innate Immune System

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.
