Cationic Immune Stimulating Complexes Containing Soluble Leishmania Antigens: Preparation, Characterization and in Vivo Immune Response Evaluation
Background: Cationic immune stimulating complexes (PLUSCOMs) are particulate antigen delivery systems. PLUSCOMs consist of cationic immunostimulatory complexes (ISCOMs) derivatives and are able to elicit in vivo T cell responses against an antigen. Objective: To evaluate the effects of PLUSCOMs containing Leishmaniamajor antigens (SLA) on the type of immune response generated in the murine mod...
متن کاملThe Nature of Antigen-antibody Complexes Formed in Rabbits during an Immune Response to Bovine Serum Albumin
The immune elimination of soluble BSA, following an intravenous injection, is accompanied by the appearance of circulating antigen-antibody complexes. The pattern of the appearance of circulating antigen-antibody complexes and the immune elimination of antigen probably depends on the amount of antigen injected, the rate of antibody synthesis, and perhaps, the quality of antibody produced. There...
متن کاملInhibition of lymphocyte mitogenesis by immobilized antigen-antibody complexes
Mouse spleen cells, cultured on surfaces coated with antigen-antibody complexes, are inhibited from responding to the B-cell mitogens, lipopolysaccharide, lipid A, Pneumococcal polysaccharide SIII, and poly I:C. The response to the T-cell mitogen, concanavalin A, is also substantially inhibited by immobilized antigen-antibody complexes, but specific inhibition of the response to phytohemaggluti...
متن کاملMIF production of lymphocytes from patients with rheumatoid arthritis with antigen-antibody complexes.
Immune complexes, human erythrocytes coated with human IgG antibody, inhibit the migration of lymphocytes from rheumatoid arthritis (RA) patients. No correlation could be observed between migration inhibition and Waaler-Rose titre (sheep cell agglutination titre) in inidvidual patients. Production of migration inhibitory factor (MIF) could be detected in 16 of 20 cultures of RA lymphocytes incu...
متن کاملپروتئین شوک حرارتی؛ کاندید واکسن سرطان
Background: Tumor cells express antigens that can be recognized by immune system as foreign particles. Heat shock proteins (HSPs) are molecular chaperones that bind to tumor antigens and mediate their uptake into antigen presenting cells. Methods: This articles is a review article and its data has been collected and categorized from the articles in the field of cancer immunotherapy. All the ar...
متن کاملEffect of antigen/antibody ratio on macrophage uptake, processing, and presentation to T cells of antigen complexed with polyclonal antibodies
Activation of a galactosidase-specific murine T hybridoma clone and of a human tetanus toxoid-specific T clone by antigen-presenting cells (APC) was used to evaluate the regulatory function of antibodies complexed with the relevant antigen. Complexed antigen, in fact, is taken up with high efficiency thanks to Fc receptors borne by APC. Antibody/antigen ratio in the complexes proved to be a cri...
