We and others have shown before that export of cytostatic drugs contributes to drug resistance. Now we provide a novel approach to overcome exosome-mediated drug resistance in aggressive B-cell lymphomas. Experimental Design: We used well-established centrifugation protocols to purify exosomes from DLBCL cell lines and detected anthracyclines using FACS and HPLC. We used shRNA knockdown of ABCA3 to determine ABCA3 dependence of chemotherapy susceptibility and monitored ABCA3 expression after indomethacin treatment using qPCR. Finally, we established an in vivo assay using a chorioallantoic membrane (CAM) assay to determine the synergy of anthracycline and indomethacin treatment. Results: We show increased efficacy of the anthracycline doxorubicin and the anthracenedione pixantrone by suppression of exosomal drug resistance with indomethacin. B-cell lymphoma cells in vitro efficiently extruded doxorubicin and pixantrone, in part compacted in exosomes. Exosomal biogenesis was critically dependent on the expression of the ATP-transporter A3 (ABCA3). Genetic or chemical depletion of ABCA3 augmented intracellular retention of both drugs and shifted the subcellular drug accumulation to prolonged nuclear retention. Indomethacin increased the cytostatic efficacy of both drugs against DLBCL cell lines in vitro and in vivo in a CAM assay. Conclusions: We propose pretreatment with indomethacin toward enhanced antitumor efficacy of anthracyclines and anthracenediones.

However, eventual disease progression leads to a fatal outcome in most cases, originating from tumor cells resisting chemotherapy. We here show that the intracellular ATP-binding cassette transporter A3 (ABCA3), previously recognized as critical for the secretion of surfactant components from type 2 pneumocytes, is expressed in non-small-cell lung cancer (NSCLC) cells. With some heterogeneity in a given specimen, expression levels detected immunohistochemically in primary cancer tissue were highest in adenocarcinomas and lowest in small cell lung cancers. Genetic silencing of ABCA3 in the NSCLC cell line models A549, NCI-H1650 and NCI-H1975 significantly increased tumor cell susceptibility to the cytostatic effects of both cisplatin (in all cell lines) and paclitaxel (in two of three cell lines). Taken together, ABCA3 emerges as a modulator of NSCLC cell susceptibility to cytostatic therapy. Copyright (c) 2013 S.

Exosomes, small membrane vesicles of endocytotic origin, have been implicated in intercellular communication processes such as the transfer of tumor cell antigens and the activation of recipient dendritic cells (DC). However, little is known about immunomodulatory functions of keratinocyte-derived exosomes. To address this question, we analysed exosome secretion of the murine keratinocyte cell line MPEK under steady state as well as inflammatory conditions (+/- IFN). These exosomes were readily taken up by bone marrow-derived DC (BMDC) in vitro resulting in a matured phenotype, as evidenced by increased CD40 expression as well as by the production of large amounts of IL-6, IL-10 and IL-12. When the transfer of antigen-specific information through exosomes was investigated, it was found that keratinocytes took up antigen (ovalbumin) and transferred it to their exosomes. However, these antigen-harbouring exosomes failed to induce antigen-specific T cell responses via BMDC. Together, this novel biological function suggests that keratinocytes are able to direct unspecific immune processes but do not elicit specific immune responses."],["dc.identifier.doi","10.1111/exd.12230"],["dc.identifier.isi","000325008600005"],["dc.identifier.pmid","24079734"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/28641"],["dc.notes.status","zu prüfen"],["dc.notes.submitter","Najko"],["dc.publisher","Wiley-blackwell"],["dc.relation.issn","0906-6705"],["dc.title","Immunostimulatory activity of murine keratinocyte-derived exosomes"],["dc.type","journal_article"],["dc.type.internalPublication","yes"],["dc.type.peerReviewed","yes"],["dc.type.status","published"],["dspace.entity.type","Publication"]]
