Gastric cancer (GC) is a malignant neoplasm originating from the epithelial cells of gastric mucosa. The pathogenesis GC intricately linked to tumor microenvironment within which reside. Tumor-associated macrophages (TAMs) primarily differentiate peripheral blood monocytes and can be broadly categorized into M1 M2 subtypes. M2-type TAMs have been shown promote growth, tissue remodeling, angiogenesis. Furthermore, they actively suppress acquired immunity, leading poorer prognosis reduced tolerance chemotherapy. Exosomes, contain myriad biologically active molecules including lipids, proteins, mRNA, noncoding RNAs, emerged as key mediators communication between TAMs. exchange these via exosomes markedly influence consequently impact progression. Recent studies elucidated correlation various clinicopathological parameters GC, such size, differentiation, infiltration depth, lymph node metastasis, TNM staging, highlighting pivotal role in development metastasis. In this review, we aim comprehensively examine bidirectional TAMs, implications alterations on immune escape, invasion, metastasis targeted therapeutic approaches for efficacy potential drug resistance strategies.

Methicillin-resistant Staphylococcus aureus (MRSA) infection, a major cause of hospital- and community-acquired pneumonia, still has high mortality rate. Extracellular vesicles (EVs), as crucial mediators intercellular communication, have significant impact on infectious diseases. However, the role EVs from alveolar macrophages (AMs) in MRSA pneumonia remains unclear. We report that AMs phagocytose release more mice with pneumonia. harboring phagocytosed exhibit proinflammatory effects induce necroptosis by delivering tumor necrosis factor α (TNF-α) miR-146a-5p. Mechanically, upregulated miR-146a-5p these enhances phosphorylation RIPK1, RIPK3, MLKL targeting TNF receptor-associated 6 (TRAF6), thereby promoting TNF-α-induced necroptosis. The combination TNF-α antagonist an antagomir effectively improves outcomes Overall, we reveal pronecrotic effect MRSA-infected provide promising target for prevention treatment

Idiopathic Pulmonary Fibrosis (IPF) is a progressive interstitial lung disease characterized by unknown etiology and limited therapeutic options. Recent studies implicate exosomal non-coding RNAs (ncRNAs) as crucial regulators in IPF. These ncRNAs, including long (lncRNAs), microRNAs (miRNAs), circular (circRNAs), are involved cellular processes through various mechanisms of selective packaging, intercellular communication, signaling pathway integration. LncRNAs such LINC00470 PVT1 exhibit pro-fibrotic effects, while others like lnc-DC THRIL show inhibitory roles; some, UCA1 MALAT1, demonstrate bidirectional regulation. In miRNAs, agents (e.g., miR-486, miR-223) contrast with miRNAs miR-34a, miR-126), miR-21 miR-155 display dual functions. Similarly, circRNAs circ_0000479 circ_0026344 promote fibrosis, whereas circ_0000072 circ_0000410 act inhibitors, certain circ_002178 circ_0001246) exhibiting complex regulatory effects. Exosomal ncRNAs modulate key pathways, TGF-β Wnt/β-catenin, influencing IPF progression. Despite their potential, challenges remain exosome isolation, functional characterization clinical translation. Addressing these barriers innovative research strategies essential to leverage the management treatment This review comprehensively examines roles IPF, elucidates interactions, discusses future perspectives enhance understanding for this disease.

Extracellular vesicles (EVs) are cell-derived lipid-bound divided into apoptotic bodies, microvesicles (MVs), and exosomes based on their biogenesis, release pathway, size, content, functions. EVs intercellular mediators that significantly affect muscle diseases such as Duchenne muscular dystrophy (DMD). DMD is a fatal X-linked disorder caused by mutations in the dystrophin gene, leading to degeneration. Mdx mice most commonly used model study disease, this study, we phenotypically characterized plasma MVs from mdx flow cytometry. Furthermore, assessed ability of modulate inflammation, damage, and/or regeneration intramuscular injection or DBA/2 control. In both mouse lineages, platelets erythrocytes were primary sources MVs, CD3+ CD4+ observed only mice. We also induced damage but not mice, while did induce either lineage. These results indicate potentially pathogenic. However, condition depends tissue status, which must be responsive due active inflammatory regenerative responses.

The physiological origins and functions of extracellular vesicles (EVs) lipoproteins (LPs) propel advancements in precision medicine by offering non-invasive diagnostic therapeutic prospects for cancers, cardiovascular, neurodegenerative diseases. However, EV/LP diagnostics (ExoLP-Dx) face considerable challenges. Their intrinsic heterogeneity, spanning biogenesis pathways, surface protein composition, concentration metrics complicate traditional approaches. Commonly used methods such as nanoparticle tracking analysis, enzyme-linked immunosorbent assay, nuclear magnetic resonance do not provide any information about their proteomic subfractions, including active proteins/enzymes involved essential pathways/functions. Size constraints limit the efficacy flow cytometry small EVs LPs, while ultracentrifugation isolation is hampered co-elution with non-target entities. In this perspective, we propose a charge-based electrokinetic membrane sensor, silica reporters providing salient features, that can overcome interference, long incubation time, sensitivity, normalization issues ExoLP-Dx from raw plasma without needing sample pretreatment/isolation. A universal standard curve obtained despite heterogeneities.
