Immune system and neuroinflammatory microenvironment

The immune system and neuroinflammatory microenvironment represent the collective cellular and molecular components within the central nervous system (CNS) that mediate inflammatory responses. This environment is primarily composed of resident glial cells, such as microglia and astrocytes, as well as infiltrating peripheral immune cells like T-cells and B-cells (Source: PMID: 30223474). Under physiological conditions, these components maintain CNS homeostasis and support neuronal health; however, chronic dysregulation leads to neuroinflammation, a hallmark of neurodegenerative diseases like Alzheimer's and Multiple Sclerosis (Source: StatPearls, Neuroinflammation). Therapeutic intervention typically focuses on modulating specific pathways within this environment—such as cytokine signaling or cellular trafficking—to mitigate neurotoxicity and promote a neuroprotective state (Source: Nature Reviews Drug Discovery). Because it encompasses a vast network of interacting cells and signaling molecules, it is considered a therapeutic landscape or system rather than a single molecular target.

Modulation of the neuroinflammatory milieu through the inhibition of leukocyte migration, depletion of specific immune cell subsets (e.g., B-cells), or alteration of microglial and astrocytic activation states to reduce pro-inflammatory cytokine production.
