Primary nephrotic syndrome (NS) is the most common glomerular disease in children. It is characterized by massive proteinuria and hypoalbuminemia. It typically has a sudden onset and more than 70% of patients will experience at least one relapse. An immunological origin has long been postulated, although the precise molecular mechanisms underlying the disease remain debated. Steroids are the first-line therapy with cumulative dose and duration of initial treatment varying among countries. Steroid-sparing agents may be indicated in case of steroid-dependency or frequent relapses...

REVIEW
Gaël S Roth, Thomas Decaens
At the moment of the diagnosis of hepatocellular carcinoma (HCC), 70% of patients have only access to palliative treatments, with very few therapeutic options. Liver immunology is very specific, and liver immunotolerance is particularly developed because of the constant and massive influx of antigens. Deregulation of hepatic immunotolerance is implicated in chronic liver diseases development and particularly in liver carcinogenesis. For these reasons, HCC may be an excellent candidate for anticancer immunotherapies such as immune checkpoint inhibitors targeting CTLA-4 and PD-L1/PD-1...

BACKGROUND: Non-operative management (NOM) of blunt splenic or liver injuries (solid organ injury, SOI) has become the standard of care in hemodynamically stable patients. However, the incidence of long-term symptoms in these patients is currently not known. The aim of this study was to assess long-term symptoms in patients undergoing successful NOM (sNOM) for SOI. METHODS: Long-term posttraumatic outcomes including chronic abdominal pain, irregular bowel movements, and recurrent infections were assessed using a specifically designed questionnaire and analyzed by univariable analysis...

Short-term outcomes of solid organ transplantation have improved dramatically over the past several decades; however, long-term survival has remained static over the same time period, and chronic rejection remains a major cause of graft failure. The importance of donor, or 'passenger', lymphocytes to the induction of tolerance to allografts was recognized in the 1990s; however, their precise contribution to graft acceptance or rejection has not been elucidated. Recently, specialized populations of tissue-resident lymphocytes in nonlymphoid organs have been described...

Hexachlorobenzene (HCB) is an organochlorine pesticide widely distributed in the environment. Chronic exposure of humans to HCB leads to a number of effects, such as triggering of porphyria, microsomal enzyme induction, thyroid dysfunctions, neurological symptoms, and immunological disorders. In animals, HCB induced hepatic porphyria, neurotoxic effects, and toxic effects on the thyroid function, reproductive system, and immune system. HCB as a dioxin-like compound and a weak ligand of the aryl hydrocarbon receptor (AhR) is a hormonal disruptor...

IgA is predominantly recognized to play an important role in host defense at mucosal sites, where it prevents invasion of pathogens by neutralization. Although it has recently become clear that IgA also mediates other immunological processes, little remains known about the potential of IgA to actively contribute to induction of inflammation, particularly in nonmucosal organs and tissues. In this article, we provide evidence that immune complex formation of serum IgA plays an important role in orchestration of inflammation in response to pathogens at various nonmucosal sites by eliciting proinflammatory cytokines by human macrophages, monocytes, and Kupffer cells...

In obesity, there are no effective therapies for parallel immune and metabolic abnormalities including systemic/tissue insulin-resistance/inflammation, adiposity and hepatic steatosis. Caffeine has anti-inflammation, anti-hepatic steatosis and anti-insulin-resistance effects. In this study, we evaluated the effects and molecular mechanisms of 6-week of caffeine treatment (HFD-caf) on immunologic and metabolic abnormalities of high-fat diet (HFD)-induced obese rats. In comparison with HFD-V rats, in HFD-caf rats the suppressed circulating immune cell inflammatory [TNFα, MCP-1, IL-6, intercellular adhesion molecule1 (ICAM-1) and nitrite] profiles were accompanied by decreased liver, white adipose tissue (WAT) and muscle' macrophages and its intracellular cytokines levels...

Cystic echinococcosis (CE) is an infectious disease caused by the larvae of parasite Echinococcus granulosus (E. granulosus). To successfully establish an infection, parasite release some substances and molecules that can modulate host immune functions, stimulating a strong anti-inflammatory reaction to carry favor to host and to reserve self-survival in the host. The literature was reviewed using MEDLINE, and an open access search for immunology of hydatidosis was performed. Accumulating data from animal experiments and human studies provided us with exciting insights into the mechanisms involved that affect all parts of immunity...

The intestinal mucosa works as a barrier to protect the internal environment of the animal from bacteria and bacterial toxins found in the gut lumen. Heat stress may harm this function. Therefore, we designed the current experiment to investigate the effect of heat stress on intestinal integrity, physiological and immunological responses and Salmonella invasion in broiler chickens. At 26 days of age, 72 birds were randomly distributed into 3 treatments, with 8 replicates per treatment and 3 birds per replicate...

The differentiation between autoimmune hepatitis (AIH) and drug-induced liver injury (DILI) is a difficult task in clinical practice. Some AIH patients had a medication history before disease onset, and some DILI patients may have positive serum antibody. In addition, these two groups of patients have similar clinical symptoms, serological examination results, and liver histopathology, which lead to the difficulties in differentiation. However, correct differential diagnosis is of great significance in making clinical treatment decisions and preventing liver cirrhosis...

Liver failure refers to a series of clinical syndromes manifesting as coagulation disorders, jaundice, hepatic encephalopathy, ascites, and other decompensated abnormalities due to serious hepatic dysfunction or decompensation in terms of synthesis, detoxification, excretion, and biological transformation caused by a variety of factors. In recent years, with the development of the research on immunological pathogenesis of liver failure, the "three-hit" theory clarifies the pathogenesis of liver failure. Major therapeutic strategies for liver failure are to prevent hepatocyte necrosis, promote hepatocyte regeneration, create a good internal environment for hepatocyte regeneration, and actively prevent and treat complications...

Current advances in immunology have led to the identification of a population of novel innate immune T cells, called mucosa-associated invariant T (MAIT) cells. The cells in humans express an invariant TCRα chain (Vα7.2-Jα33) paired with a limited subset of TCRβ chains (Vβ2, 13 and 22), are restricted by the MHC class I (MH1)-related (MR)-1, and recognize molecules that are produced in the bacterial riboflavin (vitamin B2) biosynthetic pathway. They are present in the circulation, liver and at various mucosal sites (i...

Gnathostoma turgidum is a nematode parasite that exploits the stomach of Virginian opossums, Didelphis virginiana, in Latin America. The opossum is the definitive host of G. turgidum in the wild. Intrahepatic growth and maturation of the parasite, subsequent migration to the stomach and spontaneous expulsion are common. However, the histopathological lesions caused by G. turgidum are poorly described. A better understanding of the life cycle of this parasite and the pathological changes in natural host-parasite interactions could help to clarify the progression of human infections caused by Gnathostoma binucleatum...

Dendritic cells (DC) are rare, bone marrow (BM)-derived innate immune cells that critically maintain self-tolerance in the healthy steady-state. Regulatory DC (DCreg) with capacity to suppress allograft rejection and promote transplant tolerance in pre-clinical models can readily be generated from BM precursors or circulating blood monocytes. These DCreg enhance allograft survival via various mechanisms, including promotion of regulatory T cells. In non-human primates receiving minimal immunosuppressive drug therapy (IS), infusion of DCreg of donor origin, one week before transplant, safely prolongs renal allograft survival and selectively attenuates anti-donor CD8(+) memory T cell responses in the early post-transplant period...

Cirrhosis is a liver pathology originated by hepatocytes, Kupffer and hepatic stellate cells interactions and transformations. This pathology is associated with inflammation and fibrosis, originated by molecular signals secreted by immunological and parenchymal cells, such as cytokines and chemokines, like IL-1β, IL-6, TNF-α or MCP-1, driven by Kupffer cells signals. As part of inflammation resolution, the same activated Kupffer cells contribute to anti-inflammatory effects with IL-10 and MMP-9 secretion...

Broccoli sprouts may exert a negative influence on thyroid function as they are a rich source of glucosinolates, in particular glucoraphanin. Under the study in a long-term experiment broccoli sprouts were tested as an element of rats diet, combined with deficient iodine, or sulfadimethoxine ingestion - two models of hypothyroidism. Evaluations were performed for serum TSH and thyroid hormones completed with analyzes of selected haematological, biochemical and immunological (IL-6, IL-10) parameters, as well as cytosolic glutathione peroxidase (GPX1), thioredoxin reductase (TR) in the thyroid, and plasma glutathione peroxidase (GPX3)...

The onsets of left ventricular hypertrophy (LVH) and endothelial dysfunction (ED) in diabetics, especially in those with elevated homocysteine (Hcy), precede the development of cardiovascular (CV) events. Salvianic acid A (SAA) is a renowned Traditional Chinese Medicine (TCM) that has been applied in the treatment of cardiovascular disease for many decades. In this study, we aimed (1) to investigate the CV protective effects of SAA on ameliorating LVH and ED in db/db mice with elevated blood Hcy level and (2) to decipher whether the observed CV protective effects of SAA are associated with Hcy metabolism by modulating the methylation potential and redox status in the liver of the db/db mice with elevated blood Hcy level...
