Background.: Full-house immunofluorescence in combination with various histopathologic lesions in the renal biopsies of patients without overt systemic lupus erythematosus (SLE) poses a diagnostic challenge. In this setting, the biopsy findings are sometimes termed non-lupus 'full-house nephropathy' (FHN). It is presently unknown whether idiopathic non-lupus FHN is clinicopathologically and prognostically distinct from lupus FHN. Methods.: We included non-lupus FHN patients and lupus FHN controls (four or more American College of Rheumatology or Systemic Lupus International Collaborating Clinics criteria) who were biopsied between 1968 and 2014 at the Leiden University Medical Centre...

Background.: Interstitial fibrosis (IF), tubular atrophy (TA) and interstitial inflammation (II) are known determinants of progression of renal disease. Standardized quantification of these features could add value to current classification of glomerulopathies. Methods.: We studied 315 participants in the Nephrotic Syndrome Study Network (NEPTUNE) study, including biopsy-proven minimal change disease (MCD = 98), focal segmental glomerulosclerosis (FSGS = 121), membranous nephropathy (MN = 59) and IgA nephropathy (IgAN = 37)...

OBJECTIVE: The nasal mucosa is equipped with abundant lymphatic tissues, serving as the first line of defense against invasion by microorganisms. In this study, we characterized the features of the nasal mucosa of Bama minipigs (Sus scrofa domestica) via histological analysis. METHODS: Five cross sections (I, II, III, IV, and V) were obtained from the distal end of the nasal cavity toward the pharynx (along the cavity axis) and examined. Specifically, CD3+ T cells, immunoglobulin A (IgA)+ cells, and M cells were detected by immunohistochemistry, while dendritic cells (DCs) were detected by immunofluorescence...

BACKGROUND: Recent data emphasize that thin basement membrane nephropathy (TBMN) should not be viewed as a form of benign familial hematuria since chronic renal failure (CRF) and even end-stage renal disease (ESRD), is a possible development for a subset of patients on long-term follow-up, through the onset of focal and segmental glomerulosclerosis (FSGS). We hypothesize that genetic modifiers may explain this variability of symptoms. METHODS: We looked in silico for potentially deleterious functional SNPs, using very strict criteria, in all the genes significantly expressed in the slit diaphragm (SD)...

Myunghoo Kim, Chang H Kim
The intestinal tract provides ideal niches for several different microbial species, which are collectively called the gut microbiota. A key host immune effector that controls the microbiota and prevents mucosal infection is IgA. Gut microbiota-derived factors are largely classified into molecular pattern recognition receptor ligands and nutrient-derived metabolites including short-chain fatty acids and adenosine triphosphate. Along with host-derived factors such as retinoic acid, various cytokines and cytokine-like molecules, gut microbial products profoundly shape B cell responses...

Studies demonstrated that deficiency in 17β-estradiol (E2) in postmenopausal women influences their immune system. However, few studies have reported alterations in immunologic presentation during nonnatural menopause in young females. Here we compared the differences in immune response between young C57BL/6N mice with surgical or medical variectomy and aged C57BL/6N mice with the common feature of E2 deficiency following Con A stimulation. We observed inverted CD4/CD8 ratios in the aged group and apparent reduced production of serum immunoglobin (Ig)G, IgA, and IgM in the surgical group, whereas changes in immune parameters in the medical group were moderate...

Histo-blood group antigens (HBGA) expressed on enterocytes are proposed receptors for rotaviruses and can be measured in saliva. Among 181 Pakistani infants in a G1P[8] rotavirus vaccine trial that were seronegative at baseline, anti-rotavirus IgA seroconversion rates after 3 vaccine doses differed significantly by HBGA phenotype: lowest (19%) among infants who were non-secretors (ie, do not express the carbohydrate synthesized by FUT2 gene), intermediate among non-blood group O secretors (30%) and highest (51%) among O-blood group secretors...

Most new HIV infections occur via sexual routes. The induction of protective anti-HIV antibodies in genital mucosa is an important step towards reducing HIV transmission. Mucosal anti-HIV antibodies may play a dual role by either protecting against HIV transmission or facilitating it. Protective properties against HIV of mucosal IgGs and IgAs exhibiting neutralizing or antibody dependent cell-mediated cytotoxicity (ADCC) activities have been described in highly exposed seronegative individuals (HESN). Conversely, some IgGs may facilitate the crossing of HIV free particles through epithelial barriers by transcytosis...

RATIONALE: Kidney transplantation has become standard of care for carefully selected patients living with human immunodeficiency virus (HIV) and end-stage renal disease (ESRD) in the highly active antiretroviral therapy (HAART) era. American and European prospective cohort studies have reported similar patient and graft survival compared with HIV-negative kidney transplant recipients. Despite an increased rate of acute rejection, partially due to drug interactions, HIV immunovirologic parameter generally remains under control during immunosuppression...
