OBJECTIVE: Introduction: One of the major complications of stage V chronic kidney disease (CKD), treated by program hemodialysis, are hemostatic system disturbances resulting in thrombosis development. To detect early predictors of potential thrombosis in study category of patients is rather difficult because of inflammatory process, accumulation of antibodies, continuous damage of blood elements. The aim: To estimate potential applicability of activators and inhibitors of thrombogenesis as thrombophilia markers in the patients with stage V CKD, treated by program hemodialysis...

B lymphocytes are key players in humoral immunity, expressing diverse surface immunoglobulin receptors directed against specific antigenic epitopes. The development and profile of distinct subpopulations have gained awareness in the setting of primary immunodeficiency disorders, primary or secondary autoimmunity and as therapeutic targets of specific antibodies in various diseases. The major B cell subpopulations in peripheral blood include naïve (CD19+ or CD20+ IgD+ CD27- ), non-switched memory (CD19+ or CD20+ IgD+ CD27+ ) and switched memory B cells (CD19+ or CD20+ IgD- CD27+ )...

Mycoplasma bovis is an important pathogen causing disease and substantial economic losses in cattle. However, knowledge of the dynamics of antibody responses in individual cows in the face of an outbreak is currently extremely limited. The use of commercial antibody tests to support clinical decision-making and for surveillance purposes is therefore challenging. Our objective was to describe the dynamics of M. bovis antibody responses in 4 Danish dairy herds experiencing an acute outbreak of M. bovis-associated disease, and to compare the antibody dynamics between dairy cows with different disease manifestations...

Porcine Reproductive and Respiratory Syndrome (PRRS) is an elusive model of host/virus relationship in which disease is determined by virus pathogenicity, pig breed susceptibility and phenotype, microbial infectious pressure and environmental conditions. Successful disease control in PRRS-endemic Countries corresponds to "stability", i.e. a condition with no clinical signs of PRRS in the breeding-herd population and no viremia in weaning-age pigs. The aim of this work was to compare the profile and time-course of humoral and cell-mediated immunity in stable and unstable herds, respectively...

The utility of therapeutic vaccination of bulls against Tritrichomonas foetus has been advocated in previous studies, but anecdotal reports suggest this practice does not clear infections and may additionally confound diagnostic testing by reducing parasite burdens below detectable limits. The objective of this study was to characterize the systemic humoral immune response to therapeutic vaccination in T. foetus-infected bulls over a period of four months using an indirect ELISA and to compare the dynamics of this response to culture and PCR results to establish the existence of a relationship (or lack thereof) between immunization and infection status...

BACKGROUND: Hepatitis C virus (HCV) is the most common blood-borne viral infection in the United States. Previously, we used data from the National Health and Nutrition Examination Survey (NHANES) and mortality data from the National Vital Statistics System (NVSS) to estimate the prevalence of HCV antibodies (anti-HCV) and HCV RNA among all U.S. states. However, demographic differences in HCV burden at the state-level have not been systematically described. This analysis quantified the HCV burden stratified by sex and race (and associated disparities) for each U...

REVIEW
Peter Arend
The human ABO(H) blood group phenotypes arise from the evolutionarily oldest genetic system found in primate populations. While the blood group antigen A is considered the ancestral primordial structure, under the selective pressure of life-threatening diseases blood group O(H) came to dominate as the most frequently occurring blood group worldwide. Non-O(H) phenotypes demonstrate impaired formation of adaptive and innate immunoglobulin specificities due to clonal selection and phenotype formation in plasma proteins...

Human cytomegalovirus (HCMV) infection, chronic inflammation and oxidative stress, the renin-angiotensin system (RAS), endothelial function, and DNA methylation play roles in the pathogenesis of essential hypertension (EH); however, the mechanism by which HCMV predisposes patients to hypertension remain unclear. Our group previously demonstrated an association between EH and HCMV infection in Kazakh Chinese; Here, we investigated the relationship between HCMV infection and other clinicopathological features in 720 Kazakhs individuals with or without hypertension (n = 360 each; age, 18-80)...

PROBLEM: IgG is the only antibody class, that is, actively transferred from the mother to the fetus across the placenta by an active, neonatal Fc receptor (FcRn) mediated process during pregnancy, conferring passive immunity and protection against infections to the newborn during the first months of life. Preterm infants may not receive sufficient titers of protective antibodies, as most of them are transferred only after the 34th week of gestation. Because of the great importance of this process, we investigated in a clinical setting the placental transmission of IgG antibodies in term and preterm newborns...

Incomplete curing of dental fillings may lead to leakage of methacrylate/acrylate monomers, which may come in contact with different cells of the immune system in oral tissues. Very little is known about the different immunologic effects caused by these methacrylates/acrylates. The objective of the present study was to study if and how the methacrylate/acrylate monomers ethyl methacrylate (EMA) and diethylene glycol diacrylate (DEGDA) affect the immune system in vivo and in vitro in comparison to 2-hydroxyethyl methacrylate (HEMA) and triethylene glycol dimethacrylate (TEGDMA)...

BACKGROUND: Chagas disease (CD) is a systemic parasitic infection caused by the protozoan Trypanosoma cruzi, whose chronic phase may lead to cardiac and intestinal disorders. Endemic in Latin America where it is transmitted mainly by vectors, large-scale migrations to other countries have turned CD into a global health problem because of its alternative transmission routes through blood transfusion, tissue transplantation, or congenital. Aim of this study was to compare the performance of two commercially available tests for serological diagnosis of CD in a group of Latin American migrants living in a non-endemic setting (Rome, Italy)...

BACKGROUND: Haemagglutination has been the gold standard for defining the blood group status. However, these tests depend upon the availability of specific and reliable antisera. Potent antisera for extended phenotyping are very costly, weakly reacting or available in limited stocks and unavailable for some blood group systems like Indian, Dombrock, Coltan, Diego etc. The Indian blood group system consists of two antithetical antigens, Ina and Inb . The Ina /Inb polymorphism arises from 252C > G missense mutation in the CD44 gene...

Cyclophilin A (CyPA), ubiquitously existing in cytoplasm of all eukaryotes, can be secreted in response to inflammatory stimuli. Extracellular CyPA plays a prominent role in the pathological processes of inflammatory diseases, acting as a proinflammatory mediator, exerting chemotactic effects, promoting apoptosis of endothelial cells and amplifying ROS generation, thus being considered as a potential treatment target of sepsis, a systemic inflammatory response syndrome. Our previous study found that antibodies against cyclophilin A of Clonorchis sinensis (CsCyPA) could neutralize mouse cyclophilin A (MuCyPA)...

The present study aimed to investigate whether the incorporation of flagellin, a TLR5 agonist, in the bacterial ghosts (BGs) of Salmonella Gallinarum can enhance protective immune responses against fowl typhoid, a septicemic disease of poultry, in chickens. BGs are empty cell envelopes derived from Gram-negative bacteria through the bacteriophage phiX174 gene E mediated lysis. In this study, the S. Gallinarum ghosts carrying flagellin were genetically constructed utilizing a lysis plasmid pJHL184-flagellin, designed for the coexpression of the flagellin and the lysis protein E...

Hypertension is considered as one of the cancer progressive factors, and often found comorbidity in cancer patients. Renin-angiotensin system (RAS) plays an important role in the regulation of blood pressure, and angiotensin II (Ang II) is well known pressor peptide associated with RAS. Ang II has been reported to accelerate progression and metastasis of cancer cells. However, its precise mechanisms have not been fully understood. In this study, we sought to elucidate the mechanisms by which Ang II exacerbates hematogenous metastasis in mouse melanoma cells, focusing the adhesion pathway in vascular endothelial cells...
