Question How does the human immune system fight a viral infection(immune elements involved?)



Good afternoon people,

I am currently having an issue in my microbiology class. I am trying to create a power point presentation on how our immune system fights a viral infection and the immune elements involved. My issue is that the teacher does not use the book and her power points cover this topic in an extremely scattered manner. In addition, I am having issues following the book on the processes the body undergoes from the innate immune response to the adaptive immune response (humoral and cell mediated).

For instance, what triggers the adaptive immune response? Is it the AMP's that are produced when viral proteins attach to TLR's on macrophages and neutrophils, which summons Dendritic cells to the site of infection or is it fever induced when phagocytes ingest viral antigens and secrete interleukin I (increasing phagocyte production) and TNF-A causing the hypothalamus to increase body temperature.

I am pretty much lost when it comes to cell interactions and what steps are required for chemicals to be released to cause effector cells to be created and the whole process.

If someone would be so kind as to break this down for me step by step from innate immunity to adaptive immunity response to viral infections (with chemical interactions: MHC,cytokine, etc..) so i can understand it i would extremely grateful.
