Neurons and the immune system are deeply linked. They found that anxiety is caused by a weak immune system and strengthening the immune system will lower anxiety. They have been injecting viruses into animal brains and doing gain of function edits on viruses for understanding fear responses in mammals and making them more infectious to mice and apes to study their brains after viral infection. https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4568141/ https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4568141/ >The use of viral vector technology to deliver short hairpin RNAs (shRNAs) to cells of the nervous system of many model organisms has been widely utilized by neuroscientists to study the influence of genes on behavior. However, there have been numerous reports that delivering shRNAs to the nervous system can lead to neurotoxicity. Here we report the results of a series of experiments where adeno-associated viruses (AAV), that were engineered to express shRNAs designed to target known plasticity associated genes (i.e. Arc, Egr1 and GluN2A) or control shRNAs that were designed not to target any rat gene product for depletion, were delivered to the rat basal and lateral nuclei of the amygdala (BLA), and auditory Pavlovian fear conditioning was examined. If anyone doubts the effects of infection on the brain and just says its just a mouse experiment consider the effect of mental effects of untreated syphilis. Its been observed throughout history. They only do experiments on rodents but many have been "humanized" like giving them genetic diseases like making rats that are genetically prone to depression, obesity or having fatty liver disease. They have even used human stem cells to transplant human livers into rats. https://www.upmcphysicianresources.com/news/060220-mini-liver-in-rats https://www.upmcphysicianresources.com/news/060220-mini-live...
