Elevated levels of IL-6 is associated with neuroinflammation/neurodegenerative diseases such as Alzheimer’s (AD) [1–4], Multiple Sclerosis (MS) [5, 6], Parkinson’s Disease (PD) [7, 8], Huntington’s Disease (HD) [9, 10], and HIV-Associated Neurocognitive Disorders (HAND) [11–13] as well as psychiatric disorders such as major depression [14–16] and schizophrenia [17–19]. Here, IL6 is linked to neurodegenerative disease.
