The results shown in Figure 3 are essentially unrelated to the rest of the paper. It's an experiment that they've included to claim some relevance to humans, and head off the criticism that this is a paper about mice. At best, you can argue that they show a different inflammatory marker in a group of people who were already unwell. Here's the paper describing the people from whom the 9 samples were chosen: https://www.nejm.org/doi/full/10.1056/NEJMc2033369 > We performed conventional histopathological examination of the brains of 18 patients. Fourteen patients had chronic illnesses, including diabetes and hypertension, and 11 had been found dead or had died suddenly and unexpectedly. Of the 16 patients with available medical histories, 1 had delirium, 5 had mild respiratory symptoms, 4 had acute respiratory distress syndrome, 2 had pulmonary embolism, and the symptoms were not known in 3 I can't tell which of these patients were used in this study, but...there's a lot going on with these samples. One of the patients was a meth addict, and another was a heroin addict, yet another was an alcoholic, and two others had recurrent seizures from prior head injuries! https://www.nejm.org/doi/suppl/10.1056/NEJMc2033369/suppl_fi... |
