Why is it used as a model for neuroinflammation? Describe microglia: where are they found, what role do they play, why can't that role be carried out the same way it is in the rest of the body? Mitofusin2 (Mfn2) is a mitochondrial protein. What is its apparent role? Can you think of a reason why overexpression could be protective against a stress? Is it reasonable that overexpression of this gene could also cause problems (if so, how)? How did the authors arrange that Mfn2 was only upregulated in the brain and spinal cord of TMFN mice, and not in other tissues of the mice? How do they demonstrate this? Briefly describe the roles of these molecules in immunity/inflammation:IL-1βIL-6IL-10TNFα They all belong to a class of molecules; what is that class called?
