Abstract Identifying immune escape mechanisms used by tumors may define strategies to sensitize them to immunotherapies to which they are otherwise resistant. In this study, we show that the antiapoptotic gene API5 acts as an immune escape gene in tumors by rendering them resistant to apoptosis triggered by tumor antigen-specific T cells. Its RNAi-mediated silencing in tumor cells expressing hi...
Identifying immune escape mechanisms used by tumors may define strategies to sensitize them to immunotherapies to which they are otherwise resistant. In this study, we show that the antiapoptotic gene API5 acts as an immune escape gene in tumors by rendering them resistant to apoptosis triggered by tumor antigen-specific T cells. Its RNAi-mediated silencing in tumor cells expressing high levels...
Abstract Background: Vaccination against hepatitis B surface antigen is the most effective way for prevention and has the capability to induce protective antibody levels (> 10 IU per liter) for most vaccinated people, but antibody titer has been shown to decrease over time. It is highly important to investigate this subject especially in the medical community and related professions as high-ris...
Background & Aim: Tolerance to the semi-allogenic fetal graft by the maternal immune system is a medical enigma that has stimulated investigations for a half of century. Several hypotheses have been proposed to explain the tolerance of mother to the fetus. The successful pregnancy is proposed and proved by many scientists to be a Th2 dominant phenomenon. This hypothesis is proved in most as...
Background: Falciparum malaria is a severe health burden worldwide. Antigen presenting cells are reported to be affected by erythrocytic stage of the parasite. Malarial hemozoin (HZ), a metabolite of malaria parasite, has adjuvant properties and may play a role in the induction of immune response against the parasite. Objective: To determine the immunological impact of hemozoin on the capacity ...
Antigen-specific immune tolerance has been a long-standing goal for immunotherapy for the treatment of autoimmune diseases and allergies and for the prevention of allograft rejection and anti-drug antibodies directed against biologic therapies. Nanoparticles have emerged as powerful tools to initiate and modulate immune responses due to their inherent capacity to target antigen-presenting cells...
BACKGROUND The immune response involves the activation of heterogeneous populations of T cells and B cells that show different degrees of affinity and specificity for target antigens. Although several techniques have been developed to study the molecular pathways that control immunity, there is a need for high-throughput assays to monitor the specificity of the immune response. CONTENT Antige...
