Abstract
Regenerative effects of sea anemone-derived exosomes on human foreskin fibroblasts (HFFs) were investigated. Water-based extracts from regenerating Aulactinia stella tissue were collected at various time points, and exosomes were extracted after inducing wounds. Both the extract and exosomes were tested on HFF for proliferation and in vitro wound healing. In silico analysis explored protein-protein docking between regenerative exosome proteins and HFF receptors. The MTT (3-(4,5-dimethylthiazol-2yl)-2,5 diphenyltetrazolium bromide proliferation assay and in vitro wound healing test of aquatic extract showed proliferative effects on HFF cell lines, with the 60 μg/mL concentration significantly enhancing cell migration. Exosomes were characterised. Exosomes showed a significantly positive effect on cell proliferation and migration at the 50 µg/mL concentration 48 h post-wound induction. In silico analysis revealed potential binding affinities between exosome proteins and HFF receptors. In conclusion, optimised concentrations of A. stella-derived exosomes exhibited positive effects on HFF regeneration and migration, suggesting their potential in accelerating wound healing.

Isolation and characterization of the morphology, size and particle number of rainbow trout (Oncorhynchus mykiss) and zebrafish (Danio rerio) cell line derived large and small extracellular vesicles.

Abstract
Extracellular vesicles (EVs) are 50-1,000 nm lipid bilayer-bound vesicles, released into the extracellular environment by various cell types for intercellular communication purposes. The quantitative and qualitative characteristics of EVs can be affected by stress and pathological conditions. The majority of extracellular vesicle (EV) studies have been performed on mammalian cell lines or bodily fluids. EVs have been previously described from bodily fluids like plasma, serum or mucus in different fish species, however the available knowledge of fish cell line derived EVs is limited and in the vast majority of studies, the overall focus is on small EVs (< 200 nm). We isolated large and small extracellular vesicles from zebrafish (Danio rerio) liver (ZFL), rainbow trout (Oncorhynchus mykiss) liver (RTL-W1), gill (RTgill-W1) and intestinal epithelial (RTgutGC) cell lines using stepwise centrifugation and characterized the size and morphology of EVs. Here we demonstrated that large and small extracellular vesicles can be successfully isolated using stepwise centrifugation from the serum-free medium of the selected piscine cell lines after a 24-h incubation period. The size distribution of large and small EVs isolated from the piscine cell lines suggest that large and small EV groups show high diversity in size ranges, containing heterogenous subpopulations in sizes, and the results highly depend on the applied method and whether filtration steps were included following the isolation. The spherical morphology of EVs was verified by transmission electron microscopy.

Abstract
High dietary SBM content is known to induce important physiological alterations, hampering its use as a major FM alternative. Rainbow trout (Oncorhynchus mykiss) juveniles were fed two experimental diets during 9 weeks: (i) a FM diet containing 12% FM; and (ii) a vegetable meal (VM) diet totally devoid of FM and based on SBM (26%). Fish fed the VM diet did not show reduced growth performance when compared with fish fed the FM diet. Nevertheless, fish fed the VM diet had an increased viscerosomatic index, lower apparent fat digestibility, higher aminopeptidase enzyme activity and number of villi fusions, and lower α-amylase enzyme activity and brush border integrity. Small RNA-Seq analysis identified six miRs (omy-miR-730a-5p, omy-miR-135c-5p, omy-miR-93a-3p, omy-miR-152-5p, omy-miR-133a-5p, and omy-miR-196a-3p) with higher expression in blood plasma from fish fed the VM diet. Bioinformatic prediction of target mRNAs identified several overrepresented biological processes known to be associated with high dietary SBM content (e.g., lipid metabolism, epithelial integrity disruption, and bile acid status). The present research work increases our understanding of how SBM dietary content has a physiological impact in farmed fish and suggests circulating miRs might be suitable, integrative, and less invasive biomarkers in fish.

Abstract
In recent years, extracellular vesicles (EVs) have emerged as promising biomarkers, cell-free therapeutic agents, and drug delivery carriers. Despite their great clinical potential, poor yield and unscalable production of EVs remain significant challenges. When using 3D culture methods, such as scaffolds and bioreactors, large numbers of cells can be expanded and the cell environment can be manipulated to control the cell phenotype. This has been employed to successfully increase the production of EVs as well as to enhance their therapeutic effects. The physiological relevance of 3D cultures, such as spheroids, has also provided a strategy for understanding the role of EVs in the pathogenesis of several diseases and to evaluate their role as tools to deliver drugs. Additionally, 3D culture methods can encapsulate EVs to achieve more sustained therapeutic effects as well as prevent premature clearance of EVs to enable more localised delivery and concentrated exosome dosage. This review highlights the opportunities and drawbacks of different 3D culture methods and their use in EV research.

Abstract
There is growing demand for novel biomarkers that detect early stage disease as well as monitor clinical management and therapeutic strategies. Exosome analysis could provide the next advance in attaining that goal. Exosomes are membrane encapsulated biologic nanometric-sized particles of endocytic origin which are released by all cell types. Unfortunately, exosomes are exceptionally challenging to characterize with current technologies. Exosomes are between 30 and 200nm in diameter, a size that makes them out of the sensitivity range to most cell-oriented sorting or analysis platforms, i.e., traditional flow cytometers. The most common methods for targeting exosomes to date typically involve purification followed by the characterization and the specific determination of their cargo. The whole procedure is time consuming, requiring thus skilled personnel as well as laboratory facilities and benchtop instrumentation. The most relevant methodology for exosome isolation, characterization and quantification is addressed in this chapter, including the most up-to-date approaches to explore the potential usefulness of exosomes as biomarkers in liquid biopsies and in advanced nanomedicine.

Abstract
Exosomes are small membrane-enclosed vesicles secreted by various types of cells. In mammals, a wide range of physiological and pathological functions have been confirmed and attributed to EVs carrying a variety of molecular cargoes, including miRNAs. However, studies on the biological functions and related molecular mechanisms of serum exosomes isolated from teleost fish are limited. Indeed, the molecular mechanisms underlying the effects of serum exosomes on immune responses and inflammatory processes are unknown. Chinese tongue sole (Cynoglossus semilaevis) is an economically important species used widely in industrial aquaculture. Vibrio harveyi, a common bacterial pathogen that infects C. semilaevis and some other fish, causes excessive inflammatory reactions, which are characterized by skin ulceration. Here, we isolated serum-derived exosomes from C. semilaevis and investigated their effects on inflammatory processes following V. harveyi infection. We found that compared with uninfected fish, exosome abundance in infected fish blood increased with bacterial infection time, while expression of TNF-α increased, and that of IL-10 decreased, significantly. Moreover, artificial infection studies demonstrated that injection of serum exosomes isolated from infected fish increased expression of TNF-α, IL-6, and IL-8, which is consistent with the increase in proinflammatory cytokines induced by V. harveyi infection. To further investigate the mechanisms by which exosomes increase proinflammatory cytokine production, we performed miRNA expression profiling and found that 26 differentially expressed miRNAs were associated with bacterial infection and immune responses; of these, miR-133-3p was considerably more abundant in serum exosomes from infected fish. Bioinformatics analysis suggested that miR-133-3p inhibits NF-κB signaling pathways by targeting PP2A and affecting cytokine release. We also found that miR-133-3p increased expression of TNF-α, IL-6, and IL-8 in fish blood and kidney, whereas an miR-133-3p inhibitor showed the opposite results. Thus, the data suggest that serum exosomes participate in innate immunity in teleost fish by promoting inflammatory responses to bacterial infection. Exosome-mediated transfer of miR-133-3p increases expression of proinflammatory cytokines in C. semilaevis, resulting in excessive inflammatory responses during V. harveyi infection. These data may lead to development of methods and strategies that control skin ulceration in Chinese tongue sole.

Abstract
Exosomes are a class of extracellular vesicles with diameters ranging from ~50 to 150 nm. Incorporating diverse biological substances and being present extensively in biofluids, exosomes are involved in intracellular communication in various physiological and pathological processes and emerging as promising biomarkers for the prognosis and diagnosis of many diseases. Accumulating evidence shows that exosomes also play important roles in the inflammatory and immune responses to bacterial infection. However, the study of exosomes in teleost fish remains scarce. In the present study, we focused on the exosomal microRNAs (miRNAs) in the plasma of Chinese tongue sole (Cynoglossus semilaevis) in response to Vibrio harveyi infection. After bacterial challenge, the plasma was sampled at both the early (6 and 16 h) and late stages. (48, 72, and 96 h) of infection, followed by exosome isolation and exosomal miRNA sequencing. Results showed that the expression profile of 85 exosomal miRNAs was significantly different among the control, early-, and late-infection groups. The predictive genes targeted by exosomal miRNAs were extensively involved in various inflammatory and immune processes by Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) enrichment analyses, suggesting that a series of processes were regulated by exosomal miRNAs in the plasma, including the pathogen invasion and recognition and the activation and regulation of signaling pathways related to cytokine production. Moreover, the spleen was found to be a preference for exosome enrichment and the underlying mechanism of interleukin-6 production regulated by ZC3H12A, ARID5A, and exosomal ssa-miR-146a-5p were probably present in Chinese tongue sole. Additionally, the enhanced levels of ssa-miR-146a-5p and nbr-miR-731 in plasma exosomes and the spleen of the infection groups were identified, indicating their application as biomarkers in favor of the prognosis and diagnosis of V. harveyi infection in Chinese tongue sole. Therefore, the collective results in the present study indicated the pleiotropic roles of exosomal miRNAs in the regulation of inflammatory and immune responses and their potential utilization as biomarkers in teleost fish.

Abstract
Exosomes are important mediators of intercellular communication and modulate many physiological and pathological processes. Knowledge of secretion, content, and biological functions of fish exosomes during pathological infection is still scarce due to lack of suitable standardized isolation techniques. In this study, we aimed to isolate exosomes from the plasma of marine fish, rock bream (Oplegnathus fasciatus), by two isolation methods: differential ultracentrifugation (UC) and a commercial membrane affinity spin column technique (kit). Morphological and physicochemical characteristics of the isolated exosomes were determined by these two methods, and the efficiencies of the two methods were compared. Exosomes isolated by both methods were in the expected size range (30–200 nm) and had a characteristic cup-shape in transmission electron microscopy observation. Moreover, more intact exosomes were identified using the kit-based method than UC. Nanoparticle tracking analysis demonstrated a heterogeneous population of exosomes with a mean particle diameter of 114.6 ± 4.6 and 111.2 ± 2.2 nm by UC and a kit-based method, respectively. The particle concentration obtained by the kit method (1.05 × 1011 ± 1.23 × 1010 particles/mL) was 10-fold higher than that obtained by UC (4.90 × 1010 ± 2.91 × 109 particles/mL). The kit method had a comparatively higher total protein yield (1.86 mg) and exosome protein recovery (0.55 mg/mL plasma). Immunoblotting analysis showed the presence of exosome marker proteins (CD81, CD63, and HSP90) in the exosomes isolated by both methods and suggests the existence of exosomes. However, the absence of cytotoxicity or adverse immune responses to fish and mammalian cells by the exosomes isolated by the UC procedure indicates its suitability for functional studies in vitro. Overall, our basic characterization results indicate that the kit-based method is more suitable for isolating high-purity exosomes from fish plasma, whereas UC has higher safety in terms of yielding exosomes with low toxicity. This study provides evidence for the existence of typical exosomes in rock beam plasma and facilitates the selection of an efficient exosome isolation procedure for future applications in disease diagnosis and exosome therapy as fish medicine.

Evidence for a Novel Antiviral Mechanism of Teleost Fish: Serum-Derived Exosomes Inhibit Virus Replication through Incorporating Mx1 Protein. Int J Mol Sci 2021; 22:ijms221910346.

Abstract
Exosomes are associated with cancer progression, pregnancy, cardiovascular diseases, central nervous system-related diseases, immune responses and viral pathogenicity. However, study on the role of exosomes in the immune response of teleost fish, especially antiviral immunity, is limited. Herein, serum-derived exosomes from mandarin fish were used to investigate the antiviral effect on the exosomes of teleost fish. Exosomes isolated from mandarin fish serum by ultra-centrifugation were internalized by mandarin fish fry cells and were able to inhibit Infectious spleen and kidney necrosis virus (ISKNV) infection. To further investigate the underlying mechanisms of exosomes in inhibiting ISKNV infection, the protein composition of serum-derived exosomes was analyzed by mass spectrometry. It was found that myxovirus resistance 1 (Mx1) was incorporated by exosomes. Furthermore, the mandarin fish Mx1 protein was proven to be transferred into the recipient cells though exosomes. Our results showed that the serum-derived exosomes from mandarin fish could inhibit ISKNV replication, which suggested an underlying mechanism of the exosome antivirus in that it incorporates Mx1 protein and delivery into recipient cells. This study provided evidence for the important antiviral role of exosomes in the immune system of teleost fish.

Abstract
The cargo of exosomes contains proteins with various functions, which might be promising biomarkers for disease diagnosis and prognosis. To explore the impact of the Vibrio harveyi pathogen on Cynoglossus semilaevis from a different perspective and develop promising biomarkers for infection, the exosomes from epidermal mucus of healthy controls(EC)and sick fish(ES)were extracted and identified, coupled with proteomic screening through iTRAQ followed with LC-MS/MS. 1531 credible proteins were obtained relating to structural, metabolic and immunological functions. 359 different expressed proteins (DEPs) (FC > 2 or FC < 0.5) were found, with 161 up-regulated and 198 down-regulated in ES. Based on the database of C. semilaevis on Uniprot, 71 proteins were characterized as concrete names, including 19 up-regulated proteins and 52 down-regulated proteins, and were selected as subjects for further studies. Ferritin, Toll-like receptor 5S protein and Calcium-transporting ATPase were upregulated, while Histone H2B and Eukaryotic translation initiation factor 5A were downregulated, consistent with the expression levels of related mRNAs in skin tissue verified by qRT-PCR. The integrated analysis between miRomics and proteomics also provided possible regulatory relationships mediated by mucous exosomes during infection. The signature proteins in mucosal exosomes could make sense in the explanation of the infection defending mechanism and the development of biomarkers which can differentiate diseased and healthy C. semilaevis individuals.

Abstract
Extracellular vesicles (EVs), such as exosomes, are newly recognized fundamental, universally produced natural nanoparticles of life that are seemingly involved in all biologic processes and clinical diseases. Due to their universal involvements, understanding the nature and also the potential therapeutic uses of these nanovesicles requires innovative experimental approaches in virtually every field. Of the EV group, exosome nanovesicles and larger companion micro vesicles can mediate completely new biologic and clinical processes dependent on the intercellular transfer of proteins and most importantly selected RNAs, particularly miRNAs between donor and targeted cells to elicit epigenetic alterations inducing functional cellular changes. These recipient acceptor cells are nearby (paracrine transfers) or far away after distribution via the circulation (endocrine transfers). The major properties of such vesicles seem to have been conserved over eons, suggesting that they may have ancient evolutionary origins arising perhaps even before cells in the primordial soup from which life evolved. Their potential ancient evolutionary attributes may be responsible for the ability of some modern-day exosomes to withstand unusually harsh conditions, perhaps due to unique membrane lipid compositions. This is exemplified by ability of the maternal milk exosomes to survive passing the neonatal acid/enzyme rich stomach. It is postulated that this resistance also applies to their durable presence in phagolysosomes, thus suggesting a unique intracellular release of their contained miRNAs. A major discussed issue is the generally poorly realized superiority of these naturally evolved nanovesicles for therapies when compared to human-engineered artificial nanoparticles, e.g., for the treatment of diseases like cancers.

Kisspeptin Influences the Reproductive Axis and Circulating Levels of microRNAs in Senegalese Sole. Int J Mol Sci 2020; 21:E9051. [PMID: 33260781 PMCID: PMC7730343 DOI: 10.3390/ijms21239051] [Citation(s) in RCA: 9] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/13/2020] [Revised: 11/25/2020] [Accepted: 11/26/2020] [Indexed: 12/11/2022] Open
Abstract
Kisspeptin regulates puberty and reproduction onset, acting upstream of the brain-pituitary-gonad (HPG) axis. This study aimed to test a kisspeptin-based hormonal therapy on cultured Senegalese sole (G1) breeders, known to have reproductive dysfunctions. A single intramuscular injection of KISS2-10 decapeptide (250 µg/kg) was tested in females and males during the reproductive season, and gonad maturation, sperm motility, plasma levels of gonadotropins (Fsh and Lh) and sex steroids (11-ketotestosterone, testosterone and estradiol), as well as changes in small non-coding RNAs (sncRNAs) in plasma, were investigated. Fsh, Lh, and testosterone levels increased after kisspeptin injection in both sexes, while sperm analysis did not show differences between groups. Let7e, miR-199a-3p and miR-100-5p were differentially expressed in females, while miR-1-3p miRNA was up-regulated in kisspeptin-treated males. In silico prediction of mRNAs targeted by miRNAs revealed that kisspeptin treatment might affect paracellular transporters, regulate structural and functional polarity of cells, neural networks and intracellular trafficking in Senegalese sole females; also, DNA methylation and sphingolipid metabolism might be altered in kisspeptin-treated males. Results demonstrated that kisspeptin stimulated gonadotropin and testosterone secretion in both sexes and induced an unanticipated alteration of plasma miRNAs, opening new research venues to understand how this neuropeptide impacts in fish HPG axis.

Abstract
Exosomes are important mediators of vesicle transportation and contain microRNAs (miRNAs) that mediate transcriptional gene knockout and silencing in biological processes. Moreover, exosomic miRNAs are promising biomarkers for disease diagnosis and physiological status indication in many species, including fish. The impact of the Vibrio harveyi pathogen on Cynoglossus semilaevis aquaculture is becoming more and more serious as the industry expands. To overcome this challenge, miRNAs in mucous exosomes were screened by small RNA sequencing and verified by quantitative real-time PCR to develop biomarkers. This is the first capture of exosomes from flatfish mucus coupled with miRNA profiling. The results revealed significant differences in expression levels of some miRNAs between infected and healthy fish. Three unique miRNAs were identified for V. harveyi infection diagnosis; expression levels of dre-miR-205-5p and dre-miR-205-5p in infected fish were significantly lower than controls, while dre-miR-100-5p expression was higher. These miRNAs in mucous exosomes could be used to differentiate diseased and healthy fish in an early screening method with practical value for breeding disease-resistant C. semilaevis.

Abstract
Cell-derived extracellular vesicles (EVs) participate in cell-cell communication via transfer of molecular cargo including genetic material like miRNAs. In mammals, it has previously been established that EV-mediated transfer of miRNAs can alter the development or function of immune cells, such as macrophages. Our previous research revealed that Atlantic salmon head kidney leukocytes (HKLs) change their morphology, phagocytic ability and miRNA profile from primarily “monocyte-like” at Day 1 to primarily “macrophage-like” at Day 5 of culture. Therefore, we aimed to characterize the miRNA cargo packaged in EVs released from these two cell populations. We successfully isolated EVs from Atlantic salmon HKL culture supernatants using the established Vn96 peptide-based pull-down. Isolation was validated using transmission electron microscopy, nanoparticle tracking analysis, and Western blotting. RNA-sequencing identified 19 differentially enriched (DE) miRNAs packaged in Day 1 versus Day 5 EVs. Several of the highly abundant miRNAs, including those that were DE (e.g. ssa-miR-146a, ssa-miR-155 and ssa-miR-731), were previously identified as DE in HKLs and are associated with macrophage differentiation and immune response in other species. Interestingly, the abundance relative of the miRNAs in EVs, including the most abundant miRNA (ssa-miR-125b), was different than the miRNA abundance in HKLs, indicating selective packaging of miRNAs in EVs. Further study of the miRNA cargo in EVs derived from fish immune cells will be an important next step in identifying EV biomarkers useful for evaluating immune cell function, fish health, or response to disease.

Abstract
The ninth complement component (C9) is a terminal complement component (TCC) that is involved in creating the membrane attack complex (MAC) on the target cell surface. In this study, the CsC9 (C9 of Cynoglossus semilaevis) cDNA sequence was cloned and characterized. The full-length CsC9 cDNA measured 2,150 bp, containing an open reading frame (ORF) of 1,803 bp, a 5'-untranslated region (UTR) of 24 bp and a 3'-UTR of 323 bp. A domain search revealed that the CsC9 protein contains five domains, including two TSP1s, an LDLRA, an EGF, and a MACPF. Quantitative real-time PCR analysis showed that CsC9 at the mRNA level was expressed in all the tested tissues, with the highest expression being observed in the liver. CsC9 expression is significantly upregulated in the tested tissues after challenge with Vibrio anguillarum. To further characterize the role of CsC9, peripheral blood mononuclear cells of C. semilaevis were used for transcriptome analysis after incubation with recombinant CsC9 (rCsC9) protein. A total of 3,775 significant differentially expressed genes (DEGs) were identified between the control and the rCsC9-treated group, including 2,063 upregulated genes and 1,712 downregulated genes. KEGG analyses revealed that the DEGs were enriched in cell adhesion molecules, cytokine-cytokine receptor interactions, T cell receptor signaling pathways, B cell receptor signaling pathways and Toll-like receptor signaling pathways. The results of this study indicate that in addition to participating in MAC formation, CsC9 might play multiple roles in the innate and adaptive immunity of C. semilaevis.

Abstract
BACKGROUND Piwi-interacting RNAs (piRNAs) have been linked to epigenetic and post-transcriptional gene silencing of retrotransposons in germ line cells, particularly in spermatogenesis. Exosomes are important mediators of vesicle transport, and the piRNAs in exosomes might play an important role in cell communication and signal pathway regulation. Moreover, exosomic piRNAs are promising biomarkers for disease diagnosis and physiological status indication. We used Cynoglossus semilaevis because of its commercial value and its sexual dimorphism, particularly the sex reversed "pseudomales" who have a female karyotype, produce sperm, and copulate with normal females to produce viable offspring. RESULTS To determine whether piRNAs from fish germ line cells have similar features, seminal plasma exosomes from half-smooth tongue sole, C. semilaevis, were identified, and their small RNAs were sequenced and analysed. We identified six signature piRNAs as biomarkers in exosomes of seminal plasma from males and pseudomale C. semilaevis. Bioinformatic analysis showed that all six signatures were sex-related, and four were DNA methylation-related and transposition-related piRNAs. Their expression profiles were verified using real-time quantitative PCR. The expression of the signature piRNAs was markedly higher in males than in pseudomales. The signature piRNAs could be exploited as male-specific biomarkers in this fish. CONCLUSIONS These signatures provide an effective tool to explore the regulatory mechanism of sex development in C. semilaevis and may provide guidance for future research on the function of piRNAs in the generative mechanism of sex reversed "pseudomales" in C. semilaevis.

Abstract
In mammals, small RNAs enclosed in exosomes have been identified as appropriate signatures for disease diagnosis. However, there is limited information on exosomes derived from seminal plasma, and few studies have reported analyzed the composition of exosomes and enclosed small RNAs in fish. The half-smooth tongue sole (Cynoglossus semilaevis) is an economically important fish for aquaculture, and it exhibits sexual dimorphism: the female gender show higher growth rates and larger body sizes than males. Standard karyotype analysis and artificial gynogenesis tests have revealed that this species uses heterogametic sex determination (ZW/ZZ), and so-called sex-reversed pseudo-males exist. In this study, we successfully identified exosomes in the seminal plasma of C. semilaevis; to the best of our knowledge, this is the first report of exosomes in fish seminal plasma. Analysis of the nucleotide composition showed that miRNAs were dominant in the exosomes, and the miRNAs were sequenced and compared to identify signature miRNAs as sexual biomarkers. Moreover, target genes of the signature miRNAs were predicted by sequence matching and annotation. Finally, four miRNAs (dre-miR-141-3P, dre-miR-10d-5p, ssa-miR-27b-3p, and ssa-miR-23a-3p) with significant differential expression in the males and pseudo-males were selected from the signature candidate miRNAs as markers for sex identification, and their expression profiles were verified using real-time quantitative PCR. Our findings could provide an effective detection method for sex differentiation in fish.

Abstract
It has been previously shown that inhaled zinc oxide nanoparticles (ZnO-NPs) can modulate inflammation. MicroRNAs (miRNAs) enclosed in exosomes have been identified as an important signature for inflammatory responses. However, the role of exosomal miRNAs during pathogenic inflammation has not been investigated. Healthy rats were exposed to ZnO-NPs (41.7 nm; 2, 4, and 8 mg/kg) or saline (control) via oropharyngeal aspiration. ZnO-NPs induced significant increases in the serum levels of interleukin 8 (IL-8), interleukin-1 beta (IL-1β), and tumor necrosis factor α (TNF-α), and elevated the number of cells and the percentage of neutrophils in the blood. Moreover, exposure to ZnO-NPs increased the levels of lactate dehydrogenase (LDH) activity and total protein in bronchoalveolar lavage fluid (BALF). Differential profiling of miRNAs in isolated serum exosomes revealed that 16 miRNAs were up-regulated and 7 down-regulated in ZnO-NP-treated rats compared with the controls. Functional and pathway analysis indicated that miRNAs may participate in inflammation directly and indirectly through protein and vesicle-mediated transport or regulation of IL-1, oxidative stress, apoptosis, and autophagy. These results suggest that miRNAs in serum exosomes are involved in pulmonary neutrophilic inflammation induced by ZnO-NPs.

Exosome-Mimetic Nanovesicles from Hepatocytes promote hepatocyte proliferation in vitro and liver regeneration in vivo. Sci Rep 2018; 8:2471.

Abstract
The liver has great regenerative capacity after functional mass loss caused by injury or disease. Many studies have shown that primary hepatocyte-derived exosomes, which can deliver biological information between cells, promote the regenerative process of the liver. However, the yield of exosomes is very limited. Recent studies have demonstrated that exosome-mimetic nanovesicles (NVs) can be prepared from cells with almost 100 times the production yield compared with exosomes. Thus, this study investigated the therapeutic capacity of exosome-mimetic NVs from primary hepatocytes in liver regeneration. Exosome-mimetic NVs were prepared by serial extrusions of cells through polycarbonate membranes, and the yield of these NVs was more than 100 times that of exosomes. The data indicated that the NVs could promote hepatocyte proliferation and liver regeneration by significantly enhancing the content of sphingosine kinase 2 in recipient cells. To the best of our knowledge, this is the first time that exosome-mimetic NVs from primary hepatocytes have been prepared, and these NVs have components similar to exosomes from primary hepatocytes and, in some respects, biofunctions similar to exosomes. Strategies inspired by this study may lead to substitution of exosomes with exosome-mimetic NVs for biofunctional purposes, including utilization in tissue repair and regeneration.
