How can I get to an article that explains even part of the answer to the question? The Distribution of the Human Blood Groups.

Could you help me to know, When will Scopus indexed list (2020) update appeared at website? A homozygous nonsense mutation (428G-A) in the human secretor (FUT2) gene provides resistance to symptomatic norovirus (CGII) infections. O offers virtually no immunity against cholera. For example, most native Americans belong to group O. Sign Up to Receive Our Free Coroanvirus Newsletter, Blood Disorders Affecting Red Blood Cells, Blood Disorders Affecting White Blood Cells.

Rh D protein is not reported to be expressed in brain; therefore, the likely mechanism of such an association is obscure, and given the small numbers of T gondii-infected patients involved in the study, a much larger cohort study will be required to prove the validity of this association.

What is the relationship between blood group and immune system in human? doi: https://doi.org/10.1182/blood-2010-01-261859. How Long Does Coronavirus Live On Surfaces? As discussed previously, the A→O mutation was likely driven by malaria in Africa before the migration of early humans to Europe, and CCR Δ32 has been described in skeletons from the Bronze Age.25  A combination of selection against infectious diseases, such as plague and smallpox, and genetic drift and founder effects in small populations (resulting from migration patterns of early humans) may ultimately explain the allele frequencies observed today. (Would be difficult in 20mins) Or should it be more like what was the project, why we wanted to study just this, what techniques I used, what I learned, what are my skills for the moment etc? More recent studies have linked the high frequency of the HIV-1 resistance mutation CCR5Δ32 in Europe with protection against smallpox and the Black Death.25  This proposal has also been questioned.26  The mutations A→O and CCRΔ32 occurred much earlier in human evolution than the plague and smallpox epidemics of medieval times. ABO system of blood groups in people and their resistance to... http://www.bloodjournal.org/content/115/23/4635, [Actual problems of the H blood group immunogenetics (author's transl)], Evolution of ABH blood group antigens during embryogenesis, Genetic Analysis of ABO and Rh Blood Groups in Brahmin Population of Uttar Pradesh, India”. Malaria: A mosquito's bite transmits a parasite into a person's blood, where it infects red blood cells. But positive control, negative control and other treatment groups are all positive. For stroke, people with type AB blood have an 83 percent higher risk. Treating Non-Hodgkin's Lymphoma: Your Options, Slideshow: Understanding Stem Cell Transplants for Blood Cancers. What is the difference between results, discussion, and conclusions in writing a research paper? Blood group associations with parasites, bacteria and viruses.

The relationship of ABO blood groups to duodenal and gastric ulceration. They are also at increased risk of contracting smallpox and developing cancer of the esophagus, pancreas, and stomach. In this context it is interesting to note evidence that donor human leukocyte antigen C (HLA-C) genotype has a profound impact on the outcome of liver transplants.65  HLA-C is the major inhibitory ligand for killer cell immunoglobulin-like receptors (KIRs). She recalled her mom had typical symptoms of a potential heart problem, including breathlessness, dizziness, and fatigue. Attachment of Helicobacter pylori to human gastric epithelium mediated by blood group antigens. Glycophorin as a possible receptor for Plasmodium falciparum. (Top) European location of Paleolithic refuges at the time of the last glacial maximum. B confers weaker protection against plague. : People with anemia have a low number of red blood cells. Possible evolutionary significance. Looking forward to know more on this issues as a layman, Institute of Animal Health and Veterinary BiologicalsR&T). A and B antigens can only be formed in the tissues of patients with an active FUT2 by the action of alpha-glycosyltransferases capable of transferring N-acetyl D-galactosamine or D-galactose to carbon 3 of the same glycans (Figure 1B). Secretor polymorphism and human immunodeficiency virus infection in Senegalese women. They conclude that these differences are related to loss of competition for binding HIV-1 between plasma chemokine CCR5 and Duffy on red cells in Fy(a−b−) subjects and consequent changes in the inflammatory state those infected. Larsson et al39  further demonstrated significantly lower antibody titers to norovirus GGII in nonsecretors compared with secretors.

Multiple myeloma has no cure, but stem cell transplant and/or chemotherapy can allow many people to live for years with the condition. Red cells from patients having the hybrid GPA-GPB protein Dantu, which is common in certain parts of Africa, are reported to resist invasion,111  and it has been suggested that elevated expression of Band 3 occurring in patients with the GPB-GPA-GPB MiIII protein common in South East Asia may be relevant to malaria survival.112  The importance of sialic acid on GPA in forming a receptor for P falciparum102  suggests that red cells expressing glycosylation variants of GPA found commonly in Africans in which N-acetyl D-glucosamine is present in some of the sialic acid–rich O-glycans at the N-terminus (patients with the M1 antigen113 ) may be relevant to one's susceptibility to malaria. The Duffy protein is a member of the 7 membrane-spanning chemokine receptor family (Figure 3) but unlike most chemokine receptors does not effect intracellular signaling through G proteins. Saami and Berbers—an unexpected mitochondrial DNA link. The Sla− phenotype, which results from a single nucleotide polymorphism (R1601G) in long homologous repeat D, occurs in only 1% of the white population but reaches 70% in Malians.119-121.

Liver transplantation across Rh blood group barriers increases the risk of biliary complications. Unusual selection on the KIR3DL1/S1 natural killer cell receptor in Africans. One of the most significant disease associations described for non-O (subjects of group A, B, or AB) versus O subjects is susceptibility to arterial and venous thromboembolism (VTE).8,9  Non–group O patients have a greater risk of VTE than patients of group O and have greater levels of von Willebrand factor (vWF) and factor VIII.8,10  The risk of VTE is probably related to the level of vWF and factor VIII because patients of group A2 have lower levels of these proteins than A1, B, and AB and have a lower risk of VTE.9  A, B, and H blood group antigens are expressed on N-glycans of vWF and influence the half-life of the protein (10 hours for group O and 25 hours for non-O subjects), providing an explanation for the greater levels in non-O patients.11  These observations raise the possibility that a greater propensity for blood clot formation in non-O patients conferred a survival advantage to early humans. Aplastic anemia: In people with aplastic anemia, the bone marrow does not produce enough blood cells, including red blood cells. Almost all recent cholera pandemics have emanated from this region of the world.22  Patients of group O were more susceptible in an outbreak of gastrointestinal infections caused by Escherichia coli O157 in Scotland in 1996. P. falciparum rosetting mediated by a parasite variant erythrocyte membrane protein and complement receptor 1. The H blood group deficiency results always in a more or less expressed insufficiency fo the A, B and Leb antigen production. There remains the possibility the original stimulus driving this deletion occurred in Africa as a result of selection. The concomitant occurrence of the D− phenotype in African populations resulting from a different molecular mechanism70,71  may be suggestive of some ancient selective pressure. In December 2017, at the annual meeting of the American Society of Hematology (ASH) in Atlanta, Penn and Thomas Jefferson University researchers presented new data from the Framingham Heart Study.

Functional adaptation of BabA, the H. pylori ABO blood group antigen binding adhesin. (B) Structure of Le blood group antigens in bodily secretions. The quantity of H blood group antigen produced by the H gene product, 2-alpha-fucosyltransferase, has a key importance in the A, B and Leb antigen formation. Inflammation enhances consumption and presentation of transfused RBC antigens by dendritic cells. “We haven’t put it to rest,” Kimmel said. Aquaporin 1 (AQP1), the glucose transporter (GLUT1), decay accelerating factor (DAF, CD55), and complement receptor 1 (CR1) are also shown. KIR genes are highly polymorphic and are expressed on natural killer cells and a subset of T lymphocytes.66,67  Several KIR genes (KIR2DS5, KIR3DS1, KIR2DL2) are significantly different in frequency in Basques, and 3 novel haplotypes were identified by Santin et al.68. Mollison's Blood Transfusion in Clinical Medicine. The Band 3 complex containing glycophorins A (GPA) and B (GPB) and Rh proteins, Rh-associated protein (RhAG), CD47, LW glycoprotein (intercellular adhesion molecule–4), and the junctional complex comprising glycophorins C and D (GPC, GPD), Kell glycoprotein, XK glycoprotein, and Duffy (Fy) glycoprotein. Could you please help me to know, when will Scopus indexed list (2019) update appeared at website?! Human erythrocyte glycophorin C: gene structure and rearrangement in genetic variants. Miltenberger blood group antigen type III (Mi.III) enhances the expression of band 3. Note: I am not talking about the OD values but I converted OD into pg/ml and got the negative values. This is an archived version of the Beall's list - a list of potential predatory publishers created by a librarian Jeffrey Beall. Kashan University of Medical Sciences and Health Services. Structure, function and significance of Rh proteins in red cells. A body of research has indicated an association between blood type and risk of developing coronary heart disease (CHD). The Bloodgen project: toward mass-scale comprehensive genotyping of blood donors in the European Union and beyond. Prothrombin 20210G>A is an ancestral prothrombotic mutation that occurred in whites approximately 24,000 years ago. Watchful Waiting: Is This the Choice for You? However, suggestions that smallpox selects against A, thereby explaining the high frequency of group A in Europe, and that the low frequency of O in ancient plague centers in Mongolia and the Middle East is also a reflection of selection are not supported by adequate data (Vogel et al [1960], cited in Mourant et al2(p18) ; Kreiger and Morton24 ). Comparison of genetic divergence and fitness between two subclones of Helicobacter pylori. Blood disorders can also affect the liquid portion of blood, called plasma. The secretions and tissues of a person with an active FUT2 (a secretor) can express A, B, H, and Leb antigens in those secretions according to the glycosyltransferase genes inherited. More severe anemia can cause fatigue, pale skin, and shortness of breath with exertion. Blood group, immunity, and risk of infection with Vibrio cholerae in an area of endemicity. • Some of the causes of heart disease in one blood type may be obvious, such as the link with blood type A and cholesterol. J. Anstee; The relationship between blood groups and disease. The resistance factor to Plasmodium vivax in blacks: the Duffy blood group genotype FyFy. There are many different strains of norovirus, however, and some strains bind to nonsecretor Lea structures and cause symptomatic infection.40,41 The variable specificity of different strains for ABH and Leb structures reported reflects a similar diversity to that of the aforementioned H pylori. Besides anemia, nerve damage (neuropathy) can eventually result.
