CRISPR/Cas9 technology was used to abrogate p210 oncoprotein expression in the Boff-p210 cell line, a pro-B line derived from interlukin-3-dependent Baf/3, that shows IL-3-independence arising from the constitutive expression of BCR-ABL p210. Using this approach, pools of Boff-p210-edited cells and single edited cell-derived clones were obtained and functionally studied in vitro. The loss of p210 expression in Boff-p210 cells resulted in the loss of ability to grow in the absence of IL-3, as the Baf/3 parental line, showing significantly increased apoptosis levels...

PURPOSE OF REVIEW: Cardiac allograft vasculopathy (CAV) is a major limitation to long-term survival after heart transplantation. Innovative new techniques to diagnose CAV have been applied to detect disease. This review will examine the current diagnostic and treatment options available to clinicians for CAV. RECENT FINDINGS: Diagnostic modalities addressing the pathophysiology underlying CAV (arterial wall thickening and decreased coronary blood flow) improve diagnostic sensitivity when compared to traditional (angiography and dobutamine stress echocardiography) techniques...

BACKGROUND: The predictive value of interleukin-35 (IL-35) on efficacy of immunosuppressive therapy (IST) in aplastic anemia (AA) has not been well investigated. The aim of the study was to evaluate the association between serum IL-35 level and response to IST in pediatric AA. METHODS: A total of 154 children with AA and 154 controls were included between January 2012 and December 2013. Blood and bone marrow fluid specimens were collected. Serum level of IL-35 was determined by enzyme-linked immunosorbent assay...

In the past, numerous methods have been developed to predict MHC class II binders or T-helper epitopes for designing the epitope-based vaccines against pathogens. In contrast, limited attempts have been made to develop methods for predicting T-helper epitopes/peptides that can induce a specific type of cytokine. This paper describes a method, developed for predicting interleukin-10 (IL-10) inducing peptides, a cytokine responsible for suppressing the immune system. All models were trained and tested on experimentally validated 394 IL-10 inducing and 848 non-inducing peptides...

Controversy exists as to whether African American (AA) transplant recipients are at risk for developing de novo donor-specific anti-human leukocyte antigen (HLA) antibody (dnDSA). We studied 341 HLA-mismatched, primary renal allograft recipients who were consecutively transplanted between 3/1999 and 12/2010. Sera were collected sequentially pre- and post-transplant and tested for anti-HLA immunoglobulin G (IgG) via single antigen bead assay. Of the 341 transplant patients (225 AA and 116 non-AA), 107 developed dnDSA at a median of 9...

Pemphigus is an autoimmune B-cell mediated blistering disease associated with significant morbidity and mortality. Rituximab has proven effective for the treatment of steroid-refractory pemphigus, although there is controversy over the optimum dosing protocol. Additionally, effective disease control often requires long-term immunosuppression, even in disease-free periods. We present a case series of a single-centre long-term follow up of nine patients with pemphigus, treated with two 500-mg doses of rituximab separated by 14 days along with concurrent adjuvant therapy...

Cutaneous squamous cell carcinoma (SCC) is a common cancer in white populations and its disease burden is often substantially underestimated. SCC occurs more often in men than women and increases dramatically with age; those affected often develop multiple primaries over time, which increases the burden. The main external cause is solar ultraviolet radiation (UVR), with immunosuppression being the other established risk factor, shown by the high SCC rates in organ transplant recipients. Sunbed use and certain genetic disorders and medical conditions are also associated with SCC, while associations with human papillomavirus infection and high bodyweight are not established...

The advent of checkpoint inhibitors has revolutionized systemic therapy for many malignancies, including renal cell carcinoma (RCC) where multiple PD-1, PD-L1, and CTLA-4 inhibitors have demonstrated responses and improved survival for patients in clinical trials. Durable benefit with manageable toxicity can be achieved with these agents-but unfortunately for only a minority of individuals. Efforts are ongoing to understand mechanisms driving the response and resistance to checkpoint inhibitors in order to personalize therapy and extend benefit to more patients...

Background: Vitiligo vulgaris, an acquired disease related to autoimmune activity directed against melanocytes, is a common disorder of pigmentation affecting up to one percent of the population. Several autoimmune disorders are reported to improve during pregnancy-a state of relative immunosuppression. Objectives: To assess self-reported changes in vitiligo disease activity that occurred during pregnancy. Methods: A survey of 24 subjects with vitiligo was conducted by telephone using questions that pertained to vitiligo history, pregnancy history, and vitiligo disease activity prior to, during, and after pregnancy...

: Wegener's granulomatosis is a granulomatous disorder associated with systemic necrotizing vasculitis. Eye involvement occurs in approximately 50% of Wegener's granulomatosis patients and is an important cause of morbidity. Conventional treatment-related morbidity and failure have led to studies of alternative treatment modalities. In this case of a 35-year-old man with severe Wegener's granulomatosis, conventional therapy failed to induce remission. Despite the standard immunosuppressive therapy, progression of the disease was observed, mainly with ocular manifestations and renal impairment...

Many papers have reported on pregnancy and delivery after liver transplantation, but there have been no reports on pregnancy after ABO-incompatible liver transplantation. This paper reports the first successful pregnancy and delivery of a newborn after ABO-incompatible liver transplantation for fulminant hepatic failure. The patient was a 39-year-old female. She had an ABO-incompatible liver transplantation, donated from her husband, due to subacute fulminant hepatitis of unknown etiology. She was taking tacrolimus, methylprednisolone, and mizoribine orally for the maintenance of immunosuppression at the time of discharge...

Cellular immunosuppression appears to be involved in sepsis and sepsis-induced multiple organ dysfunction syndrome (MODS). Recent evidence showed that parenteral vitamin C (Vit C) had the ability to attenuate sepsis and sepsis-induced MODS. Herein, we investigated the impact of parenteral Vit C on cellular immunosuppression and the therapeutic value in sepsis. Using cecal ligation and puncture (CLP), sepsis was induced in WT and Gulo(-/-) mice followed with 200 mg/Kg parenteral Vit C administration. The immunologic functions of CD4(+)CD25(+) regulatory T cells (Tregs) and CD4(+)CD25(-) T cells, as well as the organ functions, were determined...

Atopic dermatitis (AD) is a common chronic, pruritic skin disease in children. As the incidence of AD increases, especially in high-income countries, paediatricians may see an increasing number of recalcitrant AD cases in their practice. Although these cases are principally managed by paediatric dermatologists, it is important for paediatricians to be aware of the use and side effects of non-topical treatment like phototherapy and systemic agents as well as the evidence for alternative treatment, which caregivers may ask about...

Selective PI3Kδ inhibitors have recently been hypothesized to be appropriate immunosuppressive agents for the treatment of immunological disorders such as rheumatoid arthritis. However, few reports have highlighted molecules that are highly selective for PI3Kδ over the other PI3K isoforms. In this letter, isoform and kinome selective PI3Kδ inhibitors are presented. The Structural Activity Relationship leading to such molecules is outlined.

Immunoglobulin (Ig) A nephropathy is one of the most common primary glomerulonephritides worldwide causing end stage renal disease in up to 20-40% of affected patients, nearly two decades post diagnosis. Kidney transplantation is the treatment of choice for patients with renal failure, secondary to glomerular diseases. However, IgA nephropathy has a strong tendency to recur in the graft, and although initially thought to be a benign condition, several reports of graft loss, due to recurrent IgA nephropathy, there have been over the last three decades...

The association between transportation and the occurrence of the bovine respiratory disease complex (BRDC) has long been recognised. Many hypotheses regarding this association have been declared through the past decades, and it is agreed upon by most researchers that the multiple stressors that calves experience during transportation result in an overall immunosuppression that allows the respiratory tract to be invaded by numerous opportunistic pathogens. Furthermore, the innate immune cells, neutrophils, may be trapped in a paradox whereby their crucial defence and pathogen-killing activities are counteracted by excessive inflammation and tissue damage that may exacerbate disease, including the BRDC...

Navajo Neurohepatopathy (NNH) is a rare hepatocerebral mitochondrial DNA (mtDNA) depletion syndrome (MDS) with nonspecific clinical or pathologic features aside from Navajo ancestry. Because of the rarity of NNH, diagnosis rests on close clinicopathologic correlation and appropriate tissue triage for quantitative mtDNA analysis. We present a new case of NNH in which the clinical presentation and H&E liver biopsy histology indicated the need for NNH workup. Quantitative analysis of mtDNA in liver tissue was significantly reduced, and mutational analysis of the MPV17 gene confirmed homozygosity for the NNH-associated missense mutation, R50Q...
