Companies are moving towards quickly providing better customer-centric products and services improve market share and market size with continuously growing revenue. As such, the effective collaboration among customers, developers, suppliers, and manufacturers throughout the entire product lifecycle is becoming much more important for the most advanced(More)
Tumor-associated macrophages (TAM) with an alternatively activated phenotype have been linked to tumor-elicited inflammation, immunosuppression, and resistance to chemotherapies in cancer, thus representing an attractive target for an effective cancer immunotherapy. In this study, we demonstrate that particulate yeast-derived β-glucan, a natural(More)
Dermal IL-17-producing γδT cells have a critical role in skin inflammation. However, their development and peripheral regulation have not been fully elucidated. Here we demonstrate that dermal γδT cells develop from the embryonic thymus and undergo homeostatic proliferation after birth with diversified TCR repertoire. Vγ6T cells are bona fide resident, but(More)
A variant of the integrin-α-M (CD11b) gene has been linked to the pathogenesis of systemic lupus erythematosus. However, how this genotype results in the lupus phenotype is not fully understood. Here we show that autoreactive B cells lacking CD11b exhibit a hyperproliferative response to B cell receptor (BCR) crosslinking and enhanced survival. In vivo(More)
Salmonella are important intracellular pathogens in humans and other animal hosts. IL-24 is a novel tumour suppressor and can mediate induction of Th1-type cytokines from PBMC. However, the immunological consequences of this cytokine during intracellular pathogen infection in vivo remain unclear. In the present study, we used a virulent S. typhimurium C5(More)
There is a need to develop protective vaccines against tuberculosis (TB) that elicit full immune responses including mucosal immunity. Here, a live attenuated Salmonellatyphimurium aroA SL7207 vector TB vaccine, namely SL(E6-85B), harboring the Mycobacterium tuberculosis (M. tb) H37Rv ESAT6-Ag85B fusion gene was developed. The experimental data demonstrated(More)
Promoting complement (C) activation may enhance immunological mechanisms of anti-tumor Abs for tumor destruction. However, C activation components, such as C5a, trigger inflammation, which can promote tumor growth. We addressed the role of C5a on tumor growth by transfecting both human carcinoma and murine lymphoma with mouse C5a. In vitro growth kinetics(More)
Tuberculosis (TB) caused by Mycobacterium tuberculosis (Mtb) remains a major global health problem. Interleukin 24 (IL-24) is a novel tumor suppressor and a unique member of the IL-10 family of cytokines. However, the in vivo immunological consequences of this cytokine's activity during Mtb infection are still unknown. We found that IL-24 concentration was(More)
MicroRNAs (miRNAs) have been reported to have diverse biological roles in regulating many biological processes, including osteogenic differentiation. In the present study, we identified that miR-24 was a critical regulator during osteogenic differentiation. We found that overexpression of miR-24 significantly inhibited osteogenic differentiation, which(More)
Rheumatoid arthritis (RA) is an immune-mediated disease with a pathogenesis that involves CD4 T cell activation. Multiple immune regulatory molecules expressed on CD4(+) T cells were involved in RA pathogenesis. In this study, we investigated the role of T cell immunoglobulin and ITIM (immunoreceptor tyrosine-based inhibition motif) domain (TIGIT) in RA.(More)
