PURPOSE Reovirus is a naturally occurring oncolytic virus in clinical trials. Although tumor infection by reovirus can generate adaptive antitumor immunity, its therapeutic importance versus direct viral oncolysis is undefined. This study addresses the requirement for viral oncolysis and replication, and the relative importance of antitumor immunity and direct oncolysis in therapy. EXPERIMENT...
Photodynamic Alteration of the Surface Receptor Expression Pattern of Murine Splenic Dendritic Cells
During immune responses the initial activation of B cells takes place in T cell zones of periarteriolar lymphoid sheaths (PALS) of the splenic white pulp. After initial activation, B cells migrate into the primary follicles and, in association with follicular dendritic cells (FDCs), undergo clonal expansion and differentiation giving rise to germinal centers (GCs). Peanut agglutinin binding (PN...
Background & Objective: Dendritic cells(DCs) play an important role in directing immune response toward TH1(T-Helper 1) or TH2(T-Helper 2). These cells may induce distinct cytokine patterns in different tissues. So the pattern of cytokine induction by liver and spleen DCs may differ from each other. To investigate the difference between immune responses in the liver(as a non-lymphoid organ ...
Background: Alginate materials have been widely employed for biomedical applications ranging from wound healing to cancer treatment. However, how alginate materials affect the immune system is largely unknown. Objective: To explore the impact of alginate materials on immune system. Methods: The effect of three types of alginate materials, low viscosity, high viscosity and particulate alginate, ...
Dendritic cells (DCs) are a heterogeneous family of professional APCs involved in priming adaptive immune responses. Donor DCs (direct pathway of allorecognition) and recipient DCs presenting processed donor major histocompatibility complex (MHC) as peptides (indirect pathway of allorecognition) participate actively in graft rejection by stimulating recipient T cell responses following organ tr...
IgE, forming an immune complex with small proteins, can enhance the specific antibody and CD4(+) T cell responses in vivo. The effects require the presence of CD23 (Fcε-receptor II)(+) B cells, which capture IgE-complexed antigens (Ag) in the circulation and transport them to splenic B cell follicles. In addition, also CD11c(+) cells, which do not express CD23, are required for IgE-mediated enh...
