Intestinal immunity exists as a complex relationship among immune cells, epithelial cells, and microbiota. CCR6 and its ligand-CCL20 are highly expressed in intestinal mucosal tissues, such as Peyer's patches (PPs) and isolated lymphoid follicles (ILFs). In this study, we investigated the role of the CCR6-CCL20 axis in intestinal immunity under homeostatic conditions. CCR6 deficiency intrinsica...
Linear Paul traps (LPT) are used in many experimental studies such as mass spectrometry, atom-ion collisions, and ion-molecule reactions. Mass selective resonant quenching (MSRQ) is implemented in LPT either to identify a charged particle's mass or to remove unwanted ions from a controlled experimental environment. In the latter case, MSRQ can introduce undesired heating to co-trapped ions of d...
PURPOSE Selective immunoglobulin A deficiency is the most common primary immunodeficiency disorder that is strongly overrepresented among patients with celiac disease (CD). IgG antibodies against tissue transglutaminase (tTG) and deamidated gliadin peptides (DGP) serve as serological markers for CD in IgA deficient individuals, although the diagnostic value remains uncertain. The aim of this st...
Dr. A. Sessa, Unità Operativa di Nefrologia e Dialisi, Ospedale di Vimercate, I-20059 Vimercate (Italy) Dear Sir, The accompanying micrograph shows a typical glom-erulonephritis with mesangial electrondense deposits. The kidney biopsy was performed in a 17-year-old girl presenting the clinical picture of Berger’s disease but without IgA mesangial deposits on immunofluorescent microscopy; light ...
We treated a female patient suffering from immunoglobulin A (IgA) nephropathy and congenital deficiency of the ninth component of the complement system (C9). She was admitted with hematuria and proteinuria, and the C9 deficiency was diagnosed based on the low hemolytic activity of 50 % of the hemolytic unit of the complements (CH50) and the normal C3 level in the plasma. Renal biopsy revealed m...
Our results suggest that the prevalence of sIgA-ID is underestiSelective IgA deficiency (sIgA-ID) is the most common wellmated in the Caucasian population. It could be due to the bias in defined primary immunodeficiency disorder, with a frequency reprevalence studies with volunteer blood donors because of pathology ported to range between 1:328 in American blood donors and associated to sIgA-ID...
background: the airway surfaces are one of the most common ways of entry of infectious agents. oral cavity associated lymphoid tissues are inductive site of humoral immune responses in inflammatory and infectious disorders of the upper respiratory tract. these lymphoid tissues play important roles in the induction of salivary iga. the impact of upper respiratory tract diseases on salivary iga p...
As a defective anti-polysaccharide response can exist in the absence of an immunoglobulin deficiency, a series of 26 patients with bronchiectasis of unknown aetiology was vaccinated with a 23-valent pneumococcal polysaccharide vaccine. All patients suffered from recurrent respiratory tract infections. When measuring total antibody levels to pneumococcal serotypes 3, 4 and 9, a normal polysaccha...
