Katharina Rump, Michael Adamzik
Background: Sepsis is a common cause of death in intensive care units worldwide. Due to the high complexity of this immunological syndrome development of novel therapeutic strategies is urgent. Promising drug targets or biomarkers may depict aquaporins (AQPs) as they regulate crucial key mechanisms of sepsis. Main body: Here we report on base of the current literature that several AQPs are involved in different physiological processes of sepsis. In immune system mainly AQPs 3, 5 and 9 seem to be important, as they regulate the migration of different immune cells...

Diabetic kidney disease (DKD) is one of the major complications of diabetes mellitus (DM) and is currently the most common cause of end-stage renal disease (ESRD) worldwide. Traditionally, DKD is considered a disease which has nothing to do with the immune system, and the pathogenesis is mainly characterized to be metabolic disturbance. Recent growing evidence indicates immunologic and inflammatory mechanisms in the development and progression of DKD. This overview of macrophages, dendritic cells, T lymphocytes, B lymphocytes, neutrophils and mast cells is closely involved in the pathologic process of DKD, with more emphasis on the leucocyte accumulation and related molecular mechanisms...

Cotton rat ( Sigmodon hispidus) is a useful experimental rodent for the study of human infectious diseases. We previously clarified that cotton rats, particularly females, developed chronic kidney disease characterized by cystic lesions, inflammation, and fibrosis. The present study investigated female-associated factors for chronic kidney disease development in cotton rats. Notably, female cotton rats developed separation of the pelvic symphysis and hypertrophy in the vaginal parts of the cervix with age, which strongly associated with pyometra...

INTRODUCTION: Data suggest an additional role of T cells in antibody-mediated rejections. In 2001 a protocol for AB0-incompatible kidney transplantation based on B-cell-depleting anti-CD20 antibody rituximab, antigen-specific blood group IgG immunoadsorption, intravenous immunoglobulins, and triple immunosuppression was introduced in Europe, which used induction therapy with the use of interleukin-2 receptor antibody (IL2-RA) basiliximab. We used thymoglobulin in AB0-incompatible patients as induction in the face of high immunologic risk...

In recent years, multiple strategies for eliciting anti-tumor immunity have been developed in different clinical studies. Currently, immunotherapy was clinically validated as effective treatment option for many tumors such as melanoma, non-small cell lung cancer (NSCLC) and renal cell carcinoma (RCC). Some surface receptors of immune cells, called immune checkpoint receptors, may inhibit activity of proinflammatory lymphocytes, following binding with specific ligands. Cancer cells exploit these mechanisms to inactivate tumor-infiltrating lymphocytes (TILs) to escape from immunosurveillance...

An accumulating body of evidence suggests that renin-expressing cells have developed throughout evolution as a mechanism to preserve blood pressure and fluid volume homeostasis as well as to counteract a number of homeostatic and immunological threats. In the developing embryo, renin precursor cells emerge in multiple tissues, where they differentiate into a variety of cell types. The function of those precursors and their progeny is beginning to be unravelled. In the developing kidney, renin-expressing cells control the morphogenesis and branching of the renal arterial tree...

Group A Streptococcus (GAS) are pathogenic bacteria of the genus Streptococcus, and cause severe invasive GAS infections that comprise a wide range of diverse diseases, including acute respiratory distress syndrome, renal failure, toxic shock-like syndrome (TSLS), sepsis, cellulitis, and necrotizing fasciitis. The essential virulence, infected host, and external environmental factors required for invasive GAS infections still have not known. We demonstrated that superinfection with influenza virus and GAS induced invasive GAS infections in a mouse model, and then several investigators reported clinical cases of invasive GAS infections secondary to influenza virus infection in Japan, the United States, Canada, the United Kingdom, China, and others...

Circulating immunoglobulin M (IgM) exists in a pentameric form, possessing a polyreactive nature that responds not only to foreign antigens but also to autoantigens; thus, it is involved in both beneficial and detrimental immune responses, including protection from infection and the progression of autoimmunity. On the other hand, IgM also behaves as a carrier of the apoptosis inhibitor of macrophage (AIM) protein, storing a large amount of the inactivated form of AIM in the blood through this association. Under different disease conditions, AIM can dissociate from IgM locally or systemically to exert its function, inducing the removal of various biological debris such as excess fat, bacteria, cancer cells or dead cell debris...

Death of renal cells is central to the pathophysiology of acute tubular necrosis, autoimmunity, necrotizing glomerulonephritis, cystic kidney disease, urosepsis, delayed graft function and transplant rejection. By means of regulated necrosis, immunogenic damage-associated molecular patterns (DAMPs) and highly reactive organelles such as lysosomes, peroxisomes and mitochondria are released from the dying cells, thereby causing an overwhelming immunologic response. The rupture of the plasma membrane exhibits the "point of no return" for the immunogenicity of regulated cell death, explaining why apoptosis, a highly organized cell death subroutine with long-lasting plasma membrane integrity, elicits hardly any immune response...

In a case-controlled study, we assessed the expressed seminal NAD-dependent protein deacetylase (SIRT1) expression in infertile oligoasthenoteratozoospermic (OAT) men associated with varicocoele. Our study involved 81 men, recruited from the University hospitals, after ethical approval and informed consent. They were allocated into fertile normozoospermic men (n = 23), infertile OAT men without varicocoele (n = 23) and infertile OAT men with varicocoele (n = 35). Inclusion criteria consisted of confirmation of abnormal semen parameters and normal female partners whereas exclusion criteria were leukocytospermia, tobacco smoking, hormonal therapy, immunological disorders, dyslipidemia, hypogonadism, cardiovascular disorders, morbid obesity, and hepatic or renal failures...

High-risk localized renal cell carcinoma represents a therapeutic challenge with high recurrence rates and poor survival with nephrectomy alone. Multiple agents targeting angiogenic and immunologic pathways have demonstrated remarkable efficacy in the metastatic setting but have failed to replicate similar successes in localized disease. Study results with adjuvant anti-angiogenic therapies may have been compromised by the high incidence of treatment discontinuations or dosage reductions secondary to intolerable side effects...

In islet transplantation, in addition to immunologic and ischemic factors, the diabetic/hyperglycemic state of the recipient has been proposed, although not yet validated, as a possible cause of islet toxicity, contributing to islet loss during the engraftment period. Using a miniature swine model of islet transplantation, we have now assessed the effect of a persistent state of hyperglycemia on islet engraftment and subsequent function. An islet-kidney (IK) model previously described by our laboratory was utilized...

BACKGROUND: Transplantation is the preferred modality for renal replacement therapy in children. With increasing rates of re-transplantation within the paediatric population, there are more sensitised children on waiting lists. One issue with developing strategies to treat these children is the number of different definitions of sensitisation. and we would therefore recommend an immunological risk stratification approach. METHODS: We discuss methods of sensitisation prevention, assessment and management, including paired exchange programmes and desensitisation protocols...

Combined and sequential liver-kidney transplantation (CLKT and SLKT) is a definitive treatment in children with end-stage organ failure. There are two major indications: - terminal insufficiency of both organs, or - need for transplanting new liver as a source of lacking enzyme or specific regulator of the immune system in a patient with renal failure. A third (uncommon) option is secondary end-stage renal failure in liver transplant recipients. These three clinical settings use distinct qualification algorithms...

Renal transplantation remains the best option for patients suffering from end stage renal disease (ESRD). Given the worldwide shortage of organs and growing population of patients with ESRD, those waitlisted for a transplant is ever expanding. Contemporary crossmatch methods and human leukocyte antigen (HLA) typing play a pivotal role in improving organ allocation and afford better matches to recipients. Understanding crossmatch as well as HLA typing for renal transplantation and applying it in clinical practice is the key step to achieve a successful outcome...

Fedaey Abbas, Mohsen El Kossi, Jon Kim Jin, Ajay Sharma, Ahmed Halawa
The glomerular diseases after renal transplantation can occur de novo, i.e., with no relation to the native kidney disease, or more frequently occur as a recurrence of the original disease in the native kidney. There may not be any difference in clinical features and histological pattern between de novo glomerular disease and recurrence of original glomerular disease. However, structural alterations in transplanted kidney add to dilemma in diagnosis. These changes in architecture of histopathology can happen due to: (1) exposure to the immunosuppression specifically the calcineurin inhibitors (CNI); (2) in vascular and tubulointerstitial alterations as a result of antibody mediated or cell-mediated immunological onslaught; (3) post-transplant viral infections; (4) ischemia-reperfusion injury; and (5) hyperfiltration injury...
