This episode is about mutations especially types of mutations and their effects on proteins, genetic variation and viral antigenic drift and also answers some great questions asked by listeners about a range of things that often confuse students, such as why we are not still immune to a virus that has undergone antigenic shift, or why we have both NK cells and Tc cells (CTLs) when they both seem to do the same thing ... and more.

The whole of this episode is devoted to answering student questions, most of them about the immune system. If you only want a basic understanding of the immune system, you might want to skip this episode. It is intended for those students who want to go a little deeper and see how the puzzle pieces fit together. 

In this episode we apply what we know about the immune system to our everyday experience of disease and pathogens - and explores some of the ways that we use technology to fight the war against pathogens.  Ask your questions for discussion on the upcoming podcast: - Email to [email protected]   © 2022 Andrew Douch This work is copyright.
