In this study, exosomes used to encapsulate curcumin (Exo-cur) or a signal transducer and activator of transcription 3 (Stat3) inhibitor, i.e., JSI124 (Exo-JSI124) were delivered noninvasively to microglia cells via an intranasal route. The results generated from three inflammation-mediated disease models, i.e., a lipopolysaccharide (LPS)-induced brain(More)
Exosomal particular size of 30-100 nm matches the size criterion for nanoparticles, and opens up the possibility of using exosomes as a nanoparticle drug carrier. More importantly, exosomes released from different types of host cells have different biological effects and targeting specificities. Therefore, depending on the therapeutic goal, different types(More)
In common with many other cell types, synovial fibroblasts produce exosomes. In this study, we show that the exosomes produced by synovial fibroblasts obtained from individuals with rheumatoid arthritis (RASF), but not exosomes produced by synovial fibroblasts obtained from individuals with osteoarthritis, contain a membrane bound form of TNF-alpha as(More)
In this study, our data show that in young BXD12 mice, the implanted TS/A tumor regressed in 4 weeks after implantation, and this regression was associated with extensive T cell infiltration. In contrast, in old BXD12 mice, it was observed that there was rapid tumor growth by 7 weeks. T cell cytotoxicity against TS/A tumor cells exhibited a significant(More)
OBJECTIVE We sought to determine whether exosome-like vesicles (ELVs) released from adipose tissue play a role in activation of macrophages and subsequent development of insulin resistance in a mouse model. RESEARCH DESIGN AND METHODS ELVs released from adipose tissue were purified by sucrose gradient centrifugation and labeled with green fluorescent dye(More)
Exosomes released from tumor cells having been shown to induce interleukin-6 release from myeloid-derived suppressor cells in a Toll-like receptor 2/Stat3-dependent manner. In this study, we show that exosomes released from tumor cells re-isolated from syngeneic mice are capable of inducing interleukin-6 in a Toll-like receptor 2-independent manner, whereas(More)
Rheumatoid arthritis synovial fibroblasts (RASFs) contribute to arthritic cartilage degradation. Although RASFs are normally resistant to apoptosis, Apo2L/tumor necrosis factor-related apoptosis-inducing ligand (TRAIL)-based gene therapy has been successfully used in a mouse model of arthritis. We investigated this further by treating human RASFs with(More)
Primary meningococcal arthritis (PMA) is a relatively rare diagnosis where the role of early surgical intervention for its treatment is not well defined. We report a case of PMA in a young otherwise healthy patient who developed polyarticular joint pain secondary to Niessieria meningitidis without systemic symptoms of meningitis or meningococcemia. He(More)
