The course of IgA nephropathy (IgAN) is highly variable and ranges from a totally benign condition to end-stage renal disease in approximately one third of cases. The identification of new prognostic markers could provide insights into the pathogenesis of IgAN and unveil new therapeutic avenues. Glomerular deposition of C4d is a marker of activation of the lectin pathway of complement. It is thought that activation of the lectin pathway in IgAN is associated with more severe renal damage, and more severe histological findings...

1. Overcrowding stress is common in the poultry industry. Chickens exposed to long-term stressful situations are characterised by welfare impairment and immunosuppression. The present study evaluated the effects of a blend of essential oils (EOB; cinnamaldehyde and thymol) and stocking density on the performance, gut microflora, meat quality, and physiological stress markers of broilers. One-day-old Ross 308 male broiler chickens (n = 360) were allocated to 4 experimental groups from d 22 to 42. Each treatment had 6 replicates of 15 chicks...

Based on the analysis of data from clinical trials it could be postulated that N-acetylcysteine has a positive impact on the treatment of various diseases. However, less is known about specific molecular and physiological mechanisms underlying the reported therapeutic effects. N-acetylcysteine (NAC, N-acetyl-L-cysteine) is an amino acid derivative containing a thiol group. It is a precursor of L-cysteine and glutathione. NAC is well absorbed and safe for the body at doses up to 300 mg per kg of body weight...

BACKGROUND: Recent studies have demonstrated that immune factors might have a role in the pathophysiology of insulin resistance and type 2 diabetes mellitus (T2DM). Inappropriate glycemic control in patients with T2DM is an important risk factor for the occurrence of diabetes complications. The prevalence of celiac disease (CD) is high in type 1 diabetes mellitus however, there are scarce data about its prevalence in T2DM. Our aim was to investigate the prevalence of celiac disease among insulin-using type 2 diabetes patients with inappropriate glycemic control...

Large quantities of immunoglobulin A (IgA) are constitutively secreted by intestinal plasma cells to coat and contain the commensal microbiota, yet the specificity of these antibodies remains elusive. Here, we profiled the reactivities of single murine IgA plasma cells by cloning and characterizing large numbers of monoclonal antibodies. IgAs were not specific to individual bacterial taxa but rather polyreactive, with broad reactivity to a diverse but defined subset of microbiota. These antibodies arose at low frequencies among naïve B cells, and were selected into the IgA repertoire upon recirculation in Peyer's patches...

BACKGROUND: Patients with Sjögren's syndrome (SS) have a considerable higher risk of lymphoma development. OBJECTIVES: To determine the incidence of lymphoma and the value of biomarkers to predict lymphoma development in patients with SS. METHODS: Clinical files of all patients with a presumed diagnosis of SS between 1991 and 2016 were retrospectively reviewed for the development of lymphoma. Biochemical data were plotted as a function of the relative time before and after the lymphoma diagnosis (for patients who developed lymphoma) or before the last available blood test (for patients who did not develop lymphoma)...

Pertussis is a respiratory infection caused by Bordetella pertussis that may be particularly severe and even lethal in the first months of life when infants are still too young to be vaccinated. Adults and adolescents experience mild symptoms and are the source of infection for neonates. Adoptive maternal immunity does not prevent pertussis in the neonate. We compared the specific immune response of mothers of neonates diagnosed with pertussis and mothers of control children. We show that women have pre-existing pertussis-specific antibodies and memory B cells and react against the infection with a recall response increasing the levels specific serum IgG, milk IgA, and the frequency of memory B cells of all isotypes...

Minerals are essential for life, as they are a vital part of protein constituents, enzyme cofactors, and other components in living organisms. Deep sea water is characterized by its cleanliness and stable low temperature, and its possible health- and medical benefits are being studied. However, no study has yet evaluated the physical properties of the numerous commercially available deep sea water products, which have varying water sources and production methods. We analyzed these products' mineral content and investigated their effect on living organism, focusing on immune functions, and investigated the relation between physiological immunoactivities and mineral intake...

BACKGROUND: In children, innate and adaptive immunity varies with age, disease status, and ethnicity, reflected by lymphocyte subsets and serum immunoglobulin (Ig) levels. The paucity of such data from the Indian subcontinent necessitated this study. AIMS: This study aims to determine reference ranges of Ig and lymphocyte subsets in Indian children from birth to 5 years. SETTINGS AND DESIGN: Neonates, infants, and children from a tertiary care hospital were selected and categorized into 5 groups from cord blood/newborn to 5 years...

Daniel J Sobczynski, Omolola Eniola-Adefeso
The high abundance of immunoglobulins (Igs) in the plasma protein corona on poly(lactic-co-glycolic) acid (PLGA)-based vascular-targeted carriers (VTCs) has previously been shown to reduce their adhesion to activated endothelial cells (aECs) in human blood flow. However, the relative role of individual Ig classes (e.g., IgG, IgA, and IgM) in causing adhesion reduction remains largely unknown. Here, we characterized the influence of specific Ig classes in prescribing the binding efficiency of PLGA nano-sized VTCs in blood flow...

One of the most fascinating aspects of the immune system is its dynamism, meant as the ability to change and readapt according to the organism needs. Following an insult, we assist to the spontaneous organization of different immune cells which cooperate, locally and at distance, to build up an appropriate response. Throughout tumor progression, adaptations within the systemic tumor environment, or macroenvironment, result in the promotion of tumor growth, tumor invasion and metastasis to distal organs, but also to dramatic changes in the activity and composition of the immune system...

Toxoplasmosis is caused by Toxoplasma gondii and the probability of this infection occurring in the first months of life is usually low because its transmission is related to eating habits. A 6-month-old nursing infant was diagnosed with acute toxoplasmosis, which was identified through anti- T. gondii IgA, IgM and low-avidity IgG serologic assays, polymerase chain reaction (PCR) and mouse bioassay test although its mother was seronegative. This serological divergence between mother and child led us to interview the mother regarding epidemiological factors...

BACKGROUND: Vaccination is the most efficient means for protection against influenza. However, the various vaccines have low efficacy to protect against pandemic strains because of antigenic drift and recombination of influenza virus. Adjuvant therapy is one of the attempts to improve influenza vaccine effective cross-protection against influenza virus infection. Our previous study confirmed that 1,8-cineole inhibits the NF-κB, reduces pro-inflammatory cytokines, and relieves the pathological changes of viral pneumonia in mice infected with influenza virus...

An increased risk of cardiovascular disease (CVD) has long been recognized amongst people with autoimmune disease. It has been unclear whether this is due mainly to the ensuing treatment, particularly steroids, or whether some of this risk is due to the autoimmune process itself with subsequent inflammation. Indeed, a large body of evidence supports a role for chronic inflammation in atherogenesis, and autoantibodies have been identified as mediators in this complex inflammatory environment. Our aim is to carry out a systematic review of existing literature in order to formally establish the strength of the association between autoantibodies and atherosclerosis, amongst individuals without clinical autoimmune disease...

Dental caries is one of the most common global chronic diseases affecting all ages of the population; thus a vaccine against caries is urgently needed. Our previous studies demonstrated that a fusion protein, KF-rPAc, in which rPAc of S. mutans is directly fused to the C-terminal of E. coli-derived flagellin (KF), could confer high prophylactic and therapeutic efficiency against caries. However, possible side effects, including the high antigenicity of flagellin and possible inflammatory injury induced by flagellin, may restrict its clinical usage...
