Abstract The tuberculosis (TB) epidemic continues to be one of the largest public health challenges affecting people globally, especially due to late diagnosis, disease monitoring, and prognosis. Currently used diagnostic tools have variable sensitivity and accessibility, and many have limited ability to differentiate between latent and active TB. In case of TB, exosomes from cells infected with Mycobacterium tuberculosis (M. tuberculosis) have disease-specific antigens, microRNAs, and other molecular components, which make them potential diagnostic and prognostic biomarkers. This review focuses on previously published literature regarding the role of exosomes and exosomal antigens in TB screening and prognostication. It… More >

Abstract Background: Tumor-driven vascular remodeling is crucial for breast cancer metastasis; yet, the role of tumor-derived exosomal miRNAs in this process remains underexplored. This study aimed to investigate the clinical relevance and the underlying mechanism of breast cancer-derived exosomal miR-92b-3p in endothelial reprogramming. Methods: miR-92b-3p expression was evaluated in the TCGA cohort and clinical patient samples. The effects of exosomal miR-92b-3p from breast cancer cells on recipient human microvascular endothelial cells (HMVECs) were assessed using in vitro angiogenesis, migration, and permeability assays, alongside in vivo murine xenograft models. Mechanistic targets were validated via dual-luciferase and rescue experiments. Results: miR-92b-3p was… More >

Abstract Gut microbiota-derived exosomes (MDEs) have emerged as a novel class of drug delivery and are secreted by bacteria, fungi, and archaea in the human microbiota within the human intestinal ecosystem and possess inherent biocompatibility and lower immunogenicity, enabling seamless integration within host intestinal and systemic bioenvironments. This review elucidates the cellular and molecular mechanisms governing MDE function, explaining how their unique lipid bilayer composition facilitates cellular entry via receptor-mediated endocytosis and membrane fusion. This review discusses how gut MDEs traverse biological barriers, such as the blood-brain barrier and intestinal mucosa, by modulating tight junction proteins… More > Graphic Abstract

Abstract Acute Myeloid Leukemia (AML) is one of the most complex hematological malignancies associated with the rapid production of immature myeloid cells and poor prognosis, even with the development of therapeutic options. Exosomes, which are extracellular vesicles with sizes ranging from 30 to 150 nm, have drawn a lot of interest because of their capacity to carry molecular cargoes, including DNA, mRNA, and non-coding RNAs. Various cells produce these vesicles, which have been shown to effectively transport their molecular contents to target cells via a variety of bodily fluids. This review comprehensively discusses the importance of More >

Abstract Objective: Cone reconstruction (CR) is the preferred surgical treatment for Ebstein’s anomaly (EA). However, the molecular mechanisms underlying postoperative cardiac repair remain unclear. This study investigated the dynamic changes of plasma exosomal microRNAs (miRNAs) in EA patients before and after CR, exploring their association with postoperative cardiac function recovery and potential molecular mechanisms. Methods: Plasma samples were collected from 10 EA patients undergoing CR preoperatively, 1 day postoperatively, and 7 days postoperatively, along with samples from 10 healthy controls. Plasma exosomes were isolated using size-exclusion chromatography. Exosomal miRNAs were extracted and sequenced, followed by differential expression,… More >

Abstract Objective: Osimertinib can selectively inhibit both epidermal growth factor receptor (EGFR) sensitizing and T790M gatekeeper mutations, and has shown remarkable therapeutic effects in patients with lung adenocarcinoma. However, almost all patients inevitably develop drug resistance. Herein, we sought to clarify the roles of exosomal lncRNA H19 in modulating osimertinib resistance, focusing on the PI3K-PTEN-Akt signaling axis. Methods: Functional assays, including cell viability assay, colony formation, cell apoptosis and xenograft mouse, employed in evaluate the effects of exosomal lncRNA H19 on cell growth and apoptosis. RNA quantitation and western blot were adopted to demonstrate the regulatory roles of… More >

Abstract Long non-coding RNAs (lncRNAs) have emerged as key regulators of drug resistance in human epidermal growth factor receptor 2 (HER2)-positive breast cancer, a subtype in which both intrinsic and acquired resistance to HER2-targeted therapies remain major clinical challenges. Although mechanistic studies have begun to reveal how lncRNAs modulate signaling pathways, interact with microRNAs, and influence the tumor microenvironment, dedicated investigations in HER2-positive disease are still limited. This review synthesizes current evidence across epigenetic, transcriptional, and post-transcriptional mechanisms of resistance, including competing endogenous RNA (ceRNA) networks, RNA-binding protein interactions, and exosome-mediated intercellular communication. Particular emphasis is… More >

Abstract The last research focuses on the role of exosomes in cancer treatment. Exosomes are extracellular vesicles. They can be secreted by cancer cells, and they can modulate chemotherapy sensitivity. Determining exosomal content opens the possibility for guiding treatment strategies for cancer diseases. Exosomal microRNA are considered one of the prime candidates for exosomal biomarkers. Exosomal circular RNAs represent excellent biomarkers for liquid biopsy because of their stability in many types of cancer. Exosomal proteins remain reliable biomarkers also. Exosomes have emerged as promising therapeutic candidates. Their biological properties render them ideal vectors for drug delivery.… More >

Abstract Objectives: Metastatic spread to the lung is one of the leading causes of fatal outcomes in thyroid cancer, but the underlying molecular mechanisms remain unclear. To investigate how exosomal microRNA-17-5p (miR-17-5p) promotes lung metastasis in thyroid cancer within the framework of the “seed and soil” hypothesis. Methods: Serum exosomes from thyroid cancer lung metastasis patients and controls were analyzed for miR-17, which was elevated in metastatic cases. miR-17 was transfected into embryonic lung fibroblasts (MRC-5), and their supernatants were co-cultured with thyroid cancer cells (Cal62). Cell proliferation and migration were evaluated using colony formation, Ki67… More >

Abstract Pancreatic cancer (PC) is an extremely aggressive cancer of the digestive system with insidious onset and the lack of effective biomarkers, resulting in late-stage diagnosis and poor prognosis. Exosomal non-coding RNAs (ncRNAs) are key mediators of intercellular communication that drive PC initiation and advancement. By modulating gene expression, they impact tumor microenvironment (TME) remodeling, proliferation, migration, apoptosis, and immune evasion. Critically, exosomal ncRNAs serve as promising biomarkers for early diagnosis and prognostic assessment. This review summarizes the current research achievements regarding exosomal ncRNAs in PC, systematically elaborating on their roles in tumor occurrence, metastasis, chemoresistance More >
