Microglia are the resident immune cells of central nervous system contributing substantially to health and disease. There is increasing evidence that inflammatory microglia may induce or accelerate brain aging, by interfering with physiological repair remodeling processes. Many viral infections affect interfere functions, including human deficiency virus, flaviviruses, SARS-CoV-2, influenza, herpes viruses. Especially chronic causing low-grade neuroinflammation contribute aging.

Abstract Microglia are the resident phagocytes of brain, where they primarily function in clearance dead cells and removal un‐ or misfolded proteins. The impaired activity receptors proteins involved phagocytosis can result enhanced inflammation neurodegeneration. RNA‐seq genome‐wide association studies have linked multiple phagocytosis‐related genes to neurodegenerative diseases, while knockout such has been demonstrated exert protective effects against neurodegeneration animal models. failure microglial influences AD‐linked pathologies, including amyloid β accumulation, tau propagation, neuroinflammation, infection. However, a precise understanding microglia‐mediated Alzheimer's disease (AD) is still lacking. In this review, we summarize current knowledge molecular mechanisms AD across wide range pre‐clinical, post‐mortem , ex vivo, clinical review limitations regarding detection microglia AD. Finally, discuss rationale targeting as therapeutic strategy for preventing slowing its progression.

Toll-like receptors (TLRs), a class of pattern recognition proteins, play an integral role in the modulation systemic inflammatory responses. Cerebrovascular diseases (CVDs) are group pathological conditions that temporarily or permanently affect brain tissue mostly via decrease oxygen and glucose supply. TLRs have critical activation cascades following hypoxic-ischemic events subsequently contribute to neuroprotective detrimental effects CVD-induced neuroinflammation. The TLR signaling pathway downstream trigger immune responses production release various mediators. present review describes modulatory developed CVDs discusses potential benefits different improvement functional outcomes after ischemia.

Innate immunity is the first line of defense against invading pathogens. immune cells can recognize pathogens through recognizing pathogen-associated molecular patterns (PAMPs) via pattern recognition receptors (PRRs). The PAMPs by PRRs triggers mechanisms and secretion pro-inflammatory cytokines such as TNF-α, IL-1β, IL-6. However, sustained overwhelming activation system may disrupt homeostasis contribute to inflammatory disorders. Immunomodulators targeting be beneficial treat infectious diseases their associated complications. therapeutic performances immunomodulators negatively affected (1) high immune-mediated toxicity, (2) poor solubility (3) bioactivity loss after long circulation. Recently, nanocarriers have emerged a very promising tool overcome these obstacles owning unique properties circulation, desired bio-distribution, preferred pharmacokinetic pharmacodynamic profiles.
