One important aspect of the innate immune system that I forgot to mention previously are a group of biological molecules known as interferon. So the question that we're going to briefly address in this lecture is how exactly does our innate nonspecific immune system deal with pathogens that ultimately end up making their way into the cells of our body such as viruses and other intracellular parasites. So let's take a look at the following diagram. Let's suppose some type of virus infects our cell and this is the infected cell shown in red. So the virus injects some type of RNA or DNA into that cell infecting that cell. Now, how exactly does our innate non specific immune system deal with these types of viral and parasitic infections?
