blood donorsIgA deficientpollenSummary. In May 1994, the Blood Transfusion Centre, Sheffield, introduced a new screening test for Immunoglobulin A (IgA) deficiency. The test is performed in parallel with routine donor ABO grouping and Rh typing on two Olympus PK 7200 autoanalysers. A panel of ...
IgA deficiency results in Tfh skewing and heightened B cell responses Peyer’s patches (PPs) are important inductive sites for antibody responses to enteric antigens13. Upon examination of the small intestine of IgA-/-mice, we observed that both the number and size of PPs was increased compared...
Plasma from each of 20,068 blood donor samples collected for routine ABO and Rhesus grouping were screened for IgA deficiency using a rapid latex agglutination inhibition technique. 83 donors gave positive reactions with the latex screening reagent used. After elimination of the various false ...
The experts perfer us near deficiency. Vitamin D level and homocysteine blood tests are ones you should ask for. Iodine and vitamin D and Choline are crucial. Also the B vitamins. Additional likely deficiencies and what I take to boost my intake (I get anorexic at the drop of a hat...
Specific depletion of meningeal plasma cells or IgA deficiency resulted in reduced fungal entrapment in the peri-sinus region and increased spread into the brain following intravenous challenge, showing that meningeal IgA is essential for defending the central nervous system at this vulnerable venous ...
We further introduced these genes into blood samples for testing, and the results showed that the genes also played a crucial role in differentiating disease from control in the blood tissue. Hck is a member of the highly conserved Src family of cytoplasmic protein tyrosine kinases that transduce...
IgA deficiency worsens glucose homeostasis during HFD Given that IgA+B cells and plasma cells within the intestine were primarily affected by HFD feeding, we next sought to determine a role for IgA in obesity and IR. IgA-deficient (Igha−/−, referred to hereafter as IgA−/−) mice ...
However, we currently still lack a comprehensive understanding of how sIgA affects the microbiota in other mucosal niches, in particular the human nose. The role of sIgA in the control of the nasal microbiota is implied by individuals with selective IgA deficiency suffering frequently from allergies...

In general, IgA deficiency is often found in healthy blood donors with a defect in the differentiation of IgA cell-producing plasma B-cells but without any harm of such individuals [41]. The functions of IgA at the body sur- face are well known. IgA forms a barrier against pathogens by ...
