helicobacter pylori (h.pylori) is an etiologic factor for chronic gastritis and peptic ulcers. serological testing of h.pylori infection is common in iran, as other parts of the world. there are geographical variations in the humoral immune response to various h. pylori strains in different parts of the worl. we studied the immunogenic proteins of h.pylori by means of an immunoblot assay with a...
background: toxocariasis is a prevalent zoonosis disease caused by the closely related nematode species toxocara canis and toxocara cati which parasitise canidae and felidae respectively. in paratenic hosts, larvae of these worms cause multiple organ damage. however, how these paratenic hosts response to these worms and whether any common biomarker can be applied for diagnosis are still unclear...
Background & Aims: Sleep is a restorative process for the immune system. There are many situations in which sleep is disturbed prior to an athletic event. However, the effect of sleep deprivation on immune indices in response to exercise remains unknown. The aim of this study was to investigate the effects of sleep deprivation on serum IgG response to aerobic activity. Materials & Methods...
ABSTRACT: The effect of protein deficiency on the immune response upon primary and secondary stimulation with 5×108 sheep red blood cells (SRBC) was studied in 4 groups of mice fed by diets containing 4 or 21 percent of protein.Primary and secondary immune response were assessed by quantification of direct and indirect plaque forming cells (PFC) in immune spleens and by titration of serum hema...
Background: An increased risk for invasive infections with encapsulated bacteria such as Streptococcus pneumoniae has been described in patients with chronic kidney disease (CKD) or in those on dialysis. The aim of this study was to evaluate the antibody response to pneumococcal capsular polysaccharide vaccine in CKD patients. Methods: Sixty-six patients with CKD and 40 healthy indiv...
Abstract Despite ongoing efforts to characterize the host response toward SARS-CoV-2, a major gap in our knowledge still exists regarding magnitude and duration of humoral response. Analysis antibody mild versus moderate/severe patients, using new developed quantitative electrochemiluminescent assay for detecting IgM/IgA/IgG antibodies SARS-CoV-2 antigens, revealed rapid onset IgG/IgA antibodie...
Background: Rheumatoid arthritis (RA) is characterized by autoantibodies such as rheumatoid factor (RF) and anti-modified protein (AMPAs) like anti-citrullinated antibodies (ACPA) anti-carbamylated (anti-CarP). Recently, another AMPA: anti-acetylated (AAPA) have been found in RA patients [1]. The prevalence of AAPA their isotypes yet to be determined. Since isotype profiles reflect the breadth ...
In Leishmania (L.) major-infected BALB/c mice Th2-type cells results in disease progression, whereas C57BL/6-infected mice mount a Th1-type response, which leads to control of the infection. Th2 response correlates with IgG1 whereas, Th1 response supports switching to IgG2a subclasses. Since IgG isotype-dominated response depends on different CD4 + T cell subsets, we studied the antigenic profi...
Introduction: Due to the role of neutralizing antibodies which can prevent human cytomegalovirus (HCMV) infection, most of the efforts have been focused on designing vaccines capable of eliciting protective humoral immunity. The aim of this study was to evaluate the antibody response of BALB/c mice to a truncated HCMV glycoprotein B produced in insect cells using Baculovirus Expression Vector ...
Two H-2-linked autosomal dominant immune response (Ir) genes Ir-IgG and Ir-IgA were demonstrated to be at separate loci. Ir-IgG controls the immune response to IgG (gamma2a) myeloma proteins and Ir-IgA the immune response to IgA meyloma proteins. Both genes are associated with the H-2K region specificities of the H-2 chromosome, specifically Ir-IgG with H-2(b) and Ir-IgA with H-2(a). Different ...
