Malaria has been one of the strongest selective forces on the human genome. The increased frequency of haemoglobinopathies, as well as numerous other blood groups, in malaria endemic regions is commonly attributed to a protective effect of these alleles against malaria. In the majority of these cases however there have been no systematic functional studies to test protective mechanisms, in large part because most host-parasite interaction assays are not quantitative or scalable. We describe the development of an erythrocyte preference assay which uses differential labelling with fluorescent dyes to distinguish invasion into four different erythrocyte populations which are all co-incubated with a single Plasmodium falciparum parasite culture...

BACKGROUND: There are more than 300 known red blood cell (RBC) antigens and 33 platelet antigens that differ between individuals. Sensitisation to antigens is a serious complication that can occur in prenatal medicine and after blood transfusion, particularly for patients who require multiple transfusions. Although pre-transfusion compatibility testing largely relies on serological methods, reagents are not available for many antigens. Methods based on single-nucleotide polymorphism (SNP) arrays have been used, but typing for ABO and Rh-the most important blood groups-cannot be done with SNP typing alone...

METHODS: A review of all pancreas transplants from a single institution from 01/2003 to 07/2016 (n=606) revealed 41 recipients of a NIC donor pancreas which were matched for age, race, gender, year and type of transplant with 41 ABO identical cases. Groups were compared for allograft survival, incidence of acute cellular rejection (ACR), length of hospital stay, 3-month readmissions and transfusion requirements. Serum haptoglobin and Lactate dehydrogenase were used to identify hemolysis in patients requiring repeated transfusions without overt blood loss...

BACKGROUND: ABO subtypes are characterized by the alteration of antigens present and their expression levels on red blood cells and many are linked to genetic changes in the ABO gene. Weakened expression of antigens should be identified to prevent transfusion reactions or ABO-incompatible transplantations. Genotyping can be applied to identify subtypes to complement serologic testing. Next-generation sequencing (NGS) has shown to provide sensitive and accurate genotyping results as well as valuable cis/trans information...

Anti-nutritional factors, including hemagglutinins, are natural substances that reduce nutritional bioavailability and/or generate adverse physiological effects. Most are bitter toxic compounds, but present chemo-protective properties at low concentrations. Responses to phenylthiocarbamide (PTC) allow for an evaluation of humans' perception of bitter taste, a perception that has evolutionary advantages. Therefore, we hypothesized that relationships between food preference, dietary exposures and disease risk could reflect possible associations not only with the recognition threshold for the bitter taste of PTC, but also with ABO/Rh blood group phenotypes...

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...

Malaria is one of the most important public health problems in tropical areas on the globe. Several factors are associated with susceptibility to malaria and disease severity, including innate immunity such as blood group, hemoglobinopathy, and heme oxygenase-1 (HO-1) polymorphisms. This study was carried out to investigate association among ABO blood group, thalassemia types and HO-1 polymorphisms in malaria. The malarial blood samples were collected from patients along the Thai-Myanmar border. Determination of ABO blood group, thalassemia variants, and HO-1 polymorphisms were performed using agglutination test, low pressure liquid chromatography and polymerase chain reaction, respectively...

The incompatibility of ABO blood group between the recipient and the donor is not a barrier to perform allogeneic hematopoietic stem cell transplantation (Allo-HSCT). However, ABO incompatibility may lead to many complications during and after stem cell transplantation at the early or late period. Therefore, the typing of the blood group of the recipient and the donor should be done prior to the transplantation. In addition, the ABO/Rh group of blood products for transfusion should be determined according to the type of ABO-incompatibility...

Understanding blood group antigen binding preferences for C-type lectin receptors holds promise for modulating immune responses, since several Gram-negative bacteria express blood group antigens as molecular mimicry to evade immune responses. Herein, we report the synthesis of ABO blood group antigen active tri and disaccharides to investigate the binding specificity with various C-type lectin receptors using glycan microarray. The results of binding preferences show that distinct glycosylation on the galactose and fucose motifs are key for C-type lectin receptor binding and that these interactions occur in a Ca2+ -dependent fashion...

BACKGROUND: Type 1 diabetes mellitus (T1DM) is associated with serious micro-vascular and macro-vascular complications. Osteopontin (OPN) has emerged as a strong predictor of incipient diabetic nephropathy and a first-ever cardiovascular event in adults with T1DM. OPN is linked to coronary atherosclerosis in type 2 diabetes. The aim of the study was to test the hypothesis that OPN could be a potential marker for micro-vascular complications in children and adolescents with T1DM and we assessed its relation to carotid and aortic intima media thickness (CIMT and AIMT) as non-invasive index for subclinical atherosclerosis...
