Immune complexes (ICs) are produced during an immune response and may reflect some aspects of an ongoing immune response. Therefore, the identity of antigens incorporated into ICs provides the information that in the future may aid in the development of diagnosis and treatment strategies for autoimmune diseases, infection, cancer, and transplantation therapy, and this information might be more ...

Abstract Sepsis and autoimmune diseases remain major causes of morbidity mortality. The last decade has seen a new appreciation platelets in host defense, both immunity thrombosis. Platelets are first responders the blood to microbes or non?microbial antigens. role physiologic is counterbalanced by their pathology, for example, microvascular encounter antigens via innate adaptive immun...

Gut mucosal surfaces separate the external environment from the internal sterile environment and so represent a first line of defence system. This barrier faces environments rich in pathogens that have developed effective mechanisms for colonisation of epithelial surfaces and invasion of mucosal tissues, but also harmless antigens such as food, airborne antigens or commensal bacterial flora. Th...

partially fed (4 -5 days) h .a. anatolicum (iranian isolate) female adult ticks were used for preparation of antigens of midgut which are, the gut supernate antigen (gs), gut membrane antigen (gm), triton extracted gut membrane antigen ( tx-gm ) and sodium dodecyl sulphate treated triton extracted gut membrane antigen (sds-tx-gm). the new zealand white rabbits were immunized with gs, gm, tx- gm...

Trypanosoma cruzi antigens TSA-1 and Tc24 have shown promise as vaccine candidates in animal studies. We evaluated here the recall immune response these antigens induce in Chagasic patients, as a first step to test their immunogenicity in humans. We evaluated the in vitro cellular immune response after stimulation with recombinant TSA-1 (rTSA-1) or recombinant Tc24 (rTc24) in mononuclear cells ...

Immunological accessory molecules are proteins expressed on the surface of immune cells that canmodulate in a positive or negativemanner the ability of the cell to develop or to perform one or more of its functions. Thus, accessory molecules are critical to the success or failure of controlling the immune response to foreign antigens such as infectious agents or organ transplants, the aberrant ...
