Neuroinflammation, characterized by microglial activation and the subsequent secretion of inflammatory cytokines, plays a pivotal role in neurodegenerative diseases brain injuries, often leading to neuronal damage death. Alleviating neuroinflammation has thus emerged as promising strategy protect neurons ameliorate disorders. While peroxisome proliferator-activated receptor gamma (PPARγ) agonists have demonstrated potential therapeutic actions on neuroinflammation, their prolonged use, such with rosiglitazone, can lead cardiac risks lipid differentiation In this study, we investigated effects newly synthesized PPARγ agonist, VSP-2, cytokines BV2 cells. Treatment VSP-2 significantly reduced mRNA protein levels proinflammatory interleukin-1β (IL-1β), IL-6, tumor necrosis factor-α (TNF-α). Furthermore, attenuated phosphorylation nuclear factor kappa B (NF-κB) (65 kD) IκBα, well translocation NF-κB kD).

Microglia, the unique and motile immune cells of central nervous system (CNS), function as a security guard in maintaining CNS homeostasis, primarily through calcium signaling. The dynamics microglia control important functions such phagocytosis, cytokine release, migration. Calcium dysregulation has been linked to several disorders, like Alzheimer’s disease (AD), Parkinson’s (PD), multiple sclerosis (MS), ischemic stroke (IS). entering channels voltage-gated (VGCCs), store-operated entry (SOCE), transient receptor potential (TRP) is essential for microglial activation pro-inflammatory responses. Under pathological conditions, formation amyloid-β plaques AD, aggregation α-synuclein PD, oxidative stress MS, exacerbates neuroinflammation, mitochondrial dysfunction, neurodegeneration. Therapeutic strategies targeting signaling pathways, using channel blockers antioxidant interventions, show promise alleviating slowing down progression.
