Exosomes (EXO) are acellular vehicles used for cancer immunotherapy due to their immune inducing properties. To identify whether designed structure based on tumoral EXO have a cytotoxic effect together with a potent immunological property, we synthesized a novel structure based on EXO and staphylococcal entrotoxin B (SEB), two immune inducer substances, and(More)
A new recombinant construct made up of two components, texosomes (TEX) and staphylococcal enterotoxin B (SEB), showed cytostatic properties against several types of tumor cells in vitro. Here, we aimed to assess the construct’s antitumor immunogenicity in a murine tumor model. SEB was anchored onto purified texosomes and was used for immunization of mice(More)
Exosomes, as a mediator of cell-to-cell transfer of genetic information, act an important role in intercommunication between tumor cells and their niche including fibroblasts, endothelial cells, adipocytes and monocytes. Several studies have shown that tumor cells can influence their neighboring cells by releasing exosomes. These exosomes provide signaling(More)
BACKGROUND AND OBJECTIVES Acinetobacter spp. are important causes of nosocomial infections. They possess various antibiotic resistance mechanisms including extended spectrum beta lactamases (ESBLs). The aim of this study was to determine antibiotic resistance profile of Acinetobacter clinical isolates especially among ESBL-producing strains and to(More)
