Abstract Selective neuron death or loss, which induced by specific pathogen- and damage-associated molecular patterns (PAMPs DAMPs), was the main reason results in high morbidity, disability, mortality of transient ischemic attack (TIA) man postmenopausal women. Shank3, a key postsynaptic density, is correlated with synaptic dysfunction, oxidative stress, inflammatory, apoptosis poor outcomes stroke, although its role menopausal women TIA remains elusive. Here we discovered that Shank3 direct binds Gal-3, positive regulator aging inflammation, then regulates innate immune sensors ZBP-1, to drive inflammatory signaling cell death, PANoptosis, during TIA. Base on defeminization models (a stable female mouse OVX + model first established as well an vitro cultured primary desexualization tOGD/R model), blockade amplify stress arouse persistent behavioral deficits infarction formation, does not appear de-estrogen combination damage mice.

In addition, administration natural inhibitor, D-allose, used for food sweetener, produces anti-PANoptosis effects via activating but inhibiting ZBP-1.

Regulated cell death (RCD) triggered by innate immune activation is an important strategy for host survival during pathogen invasion and perturbations of cellular homeostasis. There are two main categories RCD, including nonlytic lytic pathways. Apoptosis the most well-characterized inflammatory pyroptosis necroptosis pathways among best known forms. While these were historically viewed as independent RCD pathways, extensive evidence cross-talk their molecular components created a knowledge gap in our mechanistic understanding pathway components, which led to identification PANoptosis. PANoptosis unique that regulated PANoptosome complexes upon sensing pathogens, pathogen-associated patterns (PAMPs), damage-associated (DAMPs) or cytokines produced downstream. Cytosolic sensors regulators, such ZBP1, AIM2 RIPK1, promote assembly PANoptosomes drive In this review, we discuss highlight mechanisms assembly, regulation identified date. We also how mutations linked diseases. Given impact specifically, across disease spectrum, improved will be critical identifying new therapeutic targets strategies.

Pyroptosis, apoptosis, necroptosis, and ferroptosis, which are the most well-studied regulated cell death (RCD) pathways, contribute to clearance of infected or potentially neoplastic cells, highlighting their importance in homeostasis, host defense against pathogens, cancer, a wide range other pathologies. Although these four RCD pathways employ distinct molecular cellular processes, emerging genetic biochemical studies have suggested remarkable flexibility crosstalk among them. The pyroptosis, apoptosis necroptosis is more evident responses infection, has led conceptualization PANoptosis.

Abstract Idiopathic Pulmonary Fibrosis (IPF) is a severe, rapidly advancing disease that drastically diminishes life expectancy. Without treatment, it can progress to lung cancer. The precise etiology of IPF remains unknown, but inflammation and damage the alveolar epithelium are widely thought be pivotal in its development. Research has indicated activating NLRP3 inflammasome crucial mechanism pathogenesis, as triggers release pro-inflammatory cytokines such IL-1β, IL-18, TGF-β. These contribute myofibroblast differentiation extracellular matrix (ECM) accumulation. Currently, treatment options for limited. Only two FDA-approved medications, pirfenidone nintedanib, available. While these drugs decelerate progression, they come with range side effects do not cure disease. Additional strategies primarily involve supportive care therapy. Emerging research highlighted numerous flavonoids derived from traditional medicines inhibit critical regulators responsible inflammasome. show promise potential therapeutic agents managing IPF, offering new avenue targets core inflammatory processes this debilitating condition.
