Monitoring antibody response to SARS-CoV-2 is critical for assessing the humoral response, especially important considering emergence of multiple variants concern (VOCs).

background: major histocompatibility complex (mhc) plays a central role in regulation and control of the immune responses to infectious diseases. due to its polymorphism, individual differences in response to vaccines have been observed in different chicken populations. studying the association of chicken mhc with immune response to vaccines will help the control of infectious disease and vacci...

Background: Apart from genetic and environmental factors, activation of autoreactive mechanisms has been proposed to play a role in the pathogenesis of schizophrenia. In re-cent years, considerable work has been carried out to understand the role and contribution of the immune system in this disease. Objective: To investigate the T cell response to phytohaemagglutinin (PHA) and determine the se...

Objective(s): Brucellosis is a common infectious disease among animals and humans. While subunit vaccines could be used as an efficient strategy against pathogens, they usually seem to be less immunogenic than live or killed vaccines. However, the use of a suitable adjuvant accompanied by subunit vaccines can be a good alternative to enhance the immune response.Materials and Methods: To find a ...

Background/Aims: Inflammatory bowel disease (IBD) is a chronic disease of the gastrointestinal tract, whose etiologies are still unknown. This study was performed to evaluate the humoral immune response in terms of B cell functions in selected IBD patients. Methods: Eighteen pediatric patients with IBD, including 12 cases of ulcerative colitis (UC) and six with Crohn disease (CD), were enrolled...

background: 1.3% of people in iran are positive for anti-hbc antibody.the objective of this study is to determine the rate of seroconversion in those with persistent isolated anti-hbc after vaccination. materials and methods: in a quasi-experimental study, 94 persons with isolated anti-hbc antibody who were referred to tehran blood transfusion organization between 2002 and 2004 were selected th...

hepatitis b virus (hbv) infection and its sequelae such as cirrhosis and hepatocellular carcinoma has remained a serious public health problem throughout the world. the who strategy for effective control of hbv infection and its complications is mass vaccination of neonates and children within the framework of expanded programme on immunization (epi). vaccination with hepatitis b surface antige...
