The pivotal role played by antigen in the clonal selection of B cells for initial participation in an immune response is well established. Antigen selective mechanisms ensure that antigen-binding antibodies are produced during all stages of the immune response. However, antibodies that lack specificity for the immunogen might also be produced during the course of an antigen-driven immune respon...

Cancer immunotherapy has emerged as a mainstream therapy option in the battle against cancer. Pre-clinical data demonstrates the ability of immunotherapy to harness the immune system to fight disseminated malignancy. Clinical translation has failed to recapitulate the promising results of pre-clinical studies although there have been some successes. In this review we explore some of the short-c...

Assessment of humoral immunity to SARS-CoV-2 and other infectious agents is typically restricted detecting antigen-specific antibodies in the serum. Rarely does immune monitoring entail assessment memory B-cell compartment itself, although it these cells that engage secondary antibody responses capable mediating protection when pre-existing fail prevent re-infection. There are few techniques ra...

Abstract Immune responses to disease are complex and the only way understand such a response is consider behavior of multiple different cell types across both innate adaptive branches immune system. We developed Barcode Enabled Antigen Mapping (BEAM) technology enable easy enrichment antigen-specific cells. This fully integrated with 10x Genomics Chromium Single Cell Profiling Solution allow mu...

a dot immunobinding assay ( dia) was used for a quantitative and qualitative assay of rubella antibody. purified antigen and conjugated anti-human immunoglobulin (rahlg) were prepared. nitrocellulose paper dotted with the antigen was added to serially diluted sera or blood samples. the reacting antibodies were visualized by a peroxidase system. development of a colored insoluble substrate was t...

  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- ...

Vitamin D plays an important role in supporting the immune system. Its expression on vital cells like B, T, and antigen-presenting has become topic of research response to current COVID-19 pandemic. The purpose vitamin is not only bones muscle development, but also its involvement regulation mood

Purpose: Injection of an antigen into the anterior chamber of the eye induces a peripheral antigen-specific immune modulation mechanism, known as anterior chamber-associated immune deviation (ACAID). Delayed-type hypersensitivity experiments argue that the subretinal space (SR) of the eye displays properties similar to ACAID. However, no investigation was performed regarding the differential im...

γδ T cells contribute uniquely to immune competence. Nevertheless, how they function remains an enigma. It is unclear what most γδ T cells recognize, what is required for them to mount an immune response, and how the γδ T cell response is integrated into host immune defense. Here, we report that a noted B cell antigen, the algae protein phycoerythrin (PE), is a murine and human γδ T cell antige...

BACKGROUND Immunotherapy offers the promise of antigen-specific suppression of pathological immune responses in conditions such as autoimmunity and organ transplantation. Substantial advances have been made in recent years in terms of understanding basic immunological mechanisms of autoreactivity, as well as clinically implementing immune-based therapies that are antigen nonspecific. OBJECTIV...
