Article Abstract
Microglia represent the main immunocompetent cell type in the parenchyma of the brain and the spinal cord, with roles extending way beyond their immune functions. While emerging data show the pivotal role of microglia in brain development, brain health and brain diseases, the exact mechanisms through which microglia contribute to complex neuroimmune interactions are still largely unclear. Understanding the communication between microglia and other cells represents an important cornerstone of these interactions, which may provide novel opportunities for therapeutic interventions in neurological or psychiatric disorders. As such, in line with studying the effects of the numerous soluble mediators that influence neuroimmune processes, attention on physical interactions between microglia and other cells in the CNS has increased substantially in recent years. In this chapter, we briefly summarize the latest literature on "microglial contactomics" and its functional implications in health and disease.

Neuroinflammation has emerged as a central and dynamic component of the pathophysiology underlying a wide range of neurodegenerative disorders, including Alzheimer's disease, Parkinson's disease, amyotrophic lateral sclerosis, Huntington's disease, and multiple sclerosis. Far from being a secondary consequence of neuronal damage, inflammatory processes (mediated by microglia, astrocytes, peripheral immune cells, and associated molecular mediators) actively shape disease onset, progression, and symptomatology. This review synthesizes current knowledge on the cellular and molecular mechanisms that govern neuroinflammatory responses, emphasizing both shared and disease-specific pathways.

Aging is a major risk factor for various neurological disorders, including Alzheimer's disease, and is associated with the accumulation of senescent cells, which can themselves propagate the senescence process through paracrine signaling. Migrasomes are organelles that form during cellular migration, detach from parent cells and mediate intercellular communication. Here we demonstrate that border-associated macrophages (BAMs) acquire senescence-associated properties during early brain aging, possibly due to prolonged exposure to amyloid beta.

Gut-mitochondria is an emerging paradigm in understanding the pathophysiology of complex neuropsychiatric disorders such as Schizophrenia (SCZ). This bidirectional communication network connects the gastrointestinal microbiota with mitochondrial function and brain health, offering novel insights into disease onset and progression. SCZ, characterized by hallucinations, delusions, cognitive impairments, and social withdrawal, has traditionally been attributed to genetic and neurochemical imbalances.

Microglia regulate neuronal circuit plasticity. Disrupting their homeostatic function has detrimental effects on neuronal circuit health. Neuroinflammation contributes to the onset and progression of neurodegenerative diseases, including Alzheimer's disease (AD), with several microglial activation genes linked to increased risk for these conditions.

Stroke is one of the leading causes of death and disability worldwide, with ischemic stroke accounting for the majority of cases. Intercellular communication is critical to its prognostic impact, and extracellular vesicles (EVs) are an emerging important mechanism. EVs are increasingly recognized as key mediators of crosstalk between neurons and glial cells, affecting processes such as neuroinflammation, oxidative stress and tissue repair.
