Tumor-associated macrophages’ (TAMs) origin, polarization, and dynamic interaction in the tumor microenvironment (TME) influence cancer development. They are essential for homeostasis, monitoring, immune protection.

Acute pancreatitis (AP) is a severe inflammatory disorder of the pancreas, characterized by high morbidity and mortality rates. Despite significant advancements in understanding pathophysiological mechanisms AP, current treatment options still face considerable limitations. Recent studies have underscored therapeutic potential quercetin, natural flavonoid, due to its potent antioxidant, anti-inflammatory, immunomodulatory properties, positioning it as promising candidate for AP. This review explores effects quercetin on highlighting antioxidant activities, role immune modulation, protective pancreatic tissue. Furthermore, examines quercetin's multi-target advantages over conventional therapies, such N-acetylcysteine corticosteroids. Although preliminary suggest that can alleviate inflammation oxidative stress clinical evidence remains limited. One main challenges application low bioavailability. Future research should focus strategies enhance bioavailability conducting large-scale randomized controlled trials more comprehensively assess efficacy safety

To explore the mechanism of Huashi Jiedu Decoction (HJD) synergizing with 5-fluorouracil (5-Fu) in gastric cancer (GC) therapy. MicroRNAs (miRNAs) and genes involved HJD-mediated GC treatment were identified using ultra-high-performance liquid chromatography coupled quadrupole-Orbitrap mass spectrometry, network pharmacology, Gene Ontology, Kyoto Encyclopedia Genes Genomes, molecular docking. The effects HJD on 5-Fu sensitivity BGC-823 cells evaluated 3-(4,5-Dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide assays, reverse transcription quantitative polymerase chain reaction (RT-qPCR), Western blotting.

Tumor-derived extracellular vesicles (TDEVs) represent a heterogeneous population of (EVs), including exosomes, microvesicles, and apoptotic bodies, which are essential for tumor growth. EVs function as natural carriers bioactive molecules, lipids, proteins, nucleic acids, enabling them to influence regulate complex cellular interactions within the microenvironment (TME). The TDEVs mainly have immunosuppressive functions result inhibitory signals disrupting immune cell anti-tumor activity. They enhance progression evasion by inhibiting effector cells altering critical processes recruitment, polarization, functional suppression different signaling pathways. In this sense, modulate NF-κB pathway, promoting inflammation inducing evasion. Janus kinase (JAK)-signal transducer activator transcription (STAT) is required TDEV-mediated manifestation tumor-supporting features. phosphoinositide 3-kinase (PI3K)/protein B (Akt)/mammalian target rapamycin (mTOR) signaling, necessary metabolic reprogramming, orchestrated TDEV abrogate response drive cancer proliferation. Finally, exosomal cargo can NOD-, LRR-, pyrin domain-containing protein 3 (NLRP3) inflammasome, activating pro-inflammatory responses that development immunomodulation. review, we take deep dive into how affect key We also examine emerging therapeutic approaches aimed at EV-mediated pathways, offering promising avenues novel EV-based immunotherapy.
