Systemic immune and neuroinflammatory milieu

The systemic immune and neuroinflammatory milieu refers to the integrated environment of signaling molecules, such as cytokines and chemokines, and immune cells that circulate systemically and within the central nervous system (Source: PubMed, PMID: 30214618). It is not a single molecular target but a complex physiological state representing the crosstalk between peripheral immunity and the brain's internal immune environment, primarily mediated by microglia and astrocytes (Source: Nature Reviews Neurology, 2020). This milieu is often dysregulated in chronic conditions, where systemic inflammation can drive or exacerbate neuroinflammatory processes, contributing to the progression of neurodegenerative diseases like Alzheimer's and Parkinson's (Source: StatPearls, Neuroinflammation). Therapeutic strategies do not target the milieu as a whole but instead focus on modulating specific components, such as Interleukin-6 (IL-6) or Tumor Necrosis Factor-alpha (TNF-alpha), to shift the environment toward a pro-resolving state (Source: PubChem, Tocilizumab). Consequently, while the milieu is a critical concept for understanding disease mechanisms and monitoring treatment efficacy, it lacks the specificity required to be classified as a discrete therapeutic target (Source: NIH, National Institute of Neurological Disorders and Stroke).
