Chronic pancreatitis (CP) is a progressive inflammatory disease of the pancreas. The currently available treatment of CP is aimed at controlling symptoms and managing complications. Unfortunately, no specific treatment is available to halt the progression of the disease process because the pathophysiological perturbations in CP are not well understood. In this review, we discuss various therapeutic targets and investigational agents acting on these targets. Among these, therapies modulating immune cells and those acting on pancreatic stellate cells appear promising and may translate into clinical benefit in near future...

Inflammatory bowel disease (IBD) is a chronic inflammatory disease of the gastrointestinal tract caused by a dysregulated immune response to the fecal microbiota. Very early-onset inflammatory bowel disease (VEO-IBD) refers to a subgroup of pediatric patients with IBD diagnosed before 6 years of age. This subgroup is often characterized by increased severity, aggressive progression, strong family history of IBD, and often poor response to conventional treatments. Nutritional therapies have been utilized to treat IBD, but their role in VEO-IBD is unclear...

Sarcoidosis, a chronic inflammatory disorder, results from increased immune responses. Its development can be triggered in patients under immunotherapy, as activation of the immune system in these patients is desired. Since 1997, 249 patients with metastasized cutaneous melanoma (stage III and IV, AJCC 2009) have been treated with dendritic cell (DC)-based vaccines at our hospital. Three out of these patients were diagnosed with sarcoidosis after or during long-term DC vaccination therapy (1.20%). Metastatic disease was initially suspected based on the radiographic manifestation of lung masses or bilateral hilar lymphadenopathy...

Direct acting antivirals can cure chronic hepatitis C virus (HCV) infection but whether they will reduce global liver disease burden is uncertain. Most chronic infections are undiagnosed and transmission has increased in recent years. The first trial of a preventive vaccine is now underway in humans at risk for HCV infection. It will test the novel hypothesis that T cell-mediated immunity alone can prevent persistent HCV infection. Another vaccine that elicits neutralizing antibodies is at an advanced stage of development...

Autoimmune regulator (Aire) plays an indispensable role in maintaining central immune tolerance by promoting the ectopic expression of tissue-restricted antigens (TRAs) in medullary thymic epithelial cells (mTECs) and dendritic cells (DCs), which lead to the deletion of autoreactive T cells or the induction of Tregs and consequently prevent autoimmune disease development. Curing autoimmune diseases has always been a challenge. DC-based immunotherapy represents a new and effective method to establish tolerance...

Segmented filamentous bacterium (SFB) a gram-positive, anaerobic, and intestinal commensal organism directly influencesthe development of Th17 helper cells in the small intestine of mice. In NOD mice, SFB colonization interferes with the developmentof type 1 diabetes (T1D), a T-cell-mediated autoimmune disease, suggesting that SFB may influence Th17 cells to inhibit Th1populations associated with the anti-β-cell immune response. This effect is a serious concern for investigators who use NOD micefor diabetes research because the expected incidence of disease decreases markedly when they are colonized by SFB...

Although genetic transfer between viruses and vertebrate hosts occurs less frequently than gene flow between bacteriophages and prokaryotes, it is extensive and has affected the evolution of both parties. With retroviruses, the integration of proviral DNA into chromosomal DNA can result in the activation of adjacent host gene expression and in the transduction of host transcripts into retroviral genomes as oncogenes. Yet in contrast to lysogenic phage, there is little evidence that viral oncogenes persist in a chain of natural transmission or that retroviral transduction is a significant driver of the horizontal spread of host genes...

Rabies virus (RABV) causes an acute progressive viral encephalitis. Although currently licensed vaccines have an excellent safety and efficacy record, the development of a safer and more cost-effective vaccine is still being sought. An E1-deleted, replication-defective human adenovirus type 5 (HAd5) vector expressing RABV glycoprotein (HAd5-G) is thought to be a promising candidate vaccine for immune prophylaxis against rabies. Salmonella enterica serovar Typhimurium (S. Typhimurium) flagellin is a well-known immune adjuvant...

Several reasons may explain why measles was not eliminated by 2015 and continues to persist in Europe, including low measles vaccination coverage, low anti-measles herd immunity levels, and the mobility of individuals with measles across Europe. The study assessed the mean measles vaccination coverage in the European Union and the WHO European region with one and two doses of measles vaccine from 1980 to 2015, and the prevalence of vaccine-induced protected individuals and anti-measles herd immunity levels in the WHO European region during 2000-2015...

We previously showed that regulatory T cells (Tregs) from T cell-specific Socs1-deficient mice (Socs1(fl/fl)Lck-Cre(+) mice) easily convert into Th1- or Th17-like cells (ex-Tregs), which lose Foxp3 expression and suppressive functions in vivo. Because Tregs in Socs1(fl/fl)Lck-Cre(+) mice are constantly exposed to a large amount of inflammatory cytokines produced by non-Tregs in vivo, in this study we analyzed Treg-specific Socs1-deficient mice (Socs1(fl/fl)Foxp3(YFP-Cre) mice). These mice developed dermatitis, splenomegaly, and lymphadenopathy that were much milder than those in Socs1(fl/fl)Lck-Cre(+) mice...

In patients with acute myeloid leukemia and low percentages of aldehyde-dehydrogenase-positive cells, non-leukemic hematopoietic stem cells can be separated from leukemic cells. By relating hematopoietic stem cell frequencies to outcome we detected poor overall- and disease-free survival of patients with low hematopoietic stem cell frequencies. Serial analysis of matched diagnostic and follow-up samples further demonstrated that hematopoietic stem cells increased after chemotherapy in patients that achieved durable remissions...

Advancement in flow cytometry reagents and instrumentation has allowed for simultaneous analysis of large numbers of lineage/functional immune cell markers. Highly complex datasets generated by polychromatic flow cytometry require proper analytical software to answer investigators' questions. A problem among many investigators and flow cytometry Shared Resource Laboratories (SRLs), including our own, is a lack of access to a flow cytometry-knowledgeable bioinformatics team, making it difficult to learn and choose appropriate analysis tool(s)...

The Aryl-hydrocarbon-receptor (AhR) is a ligand-activated transcription factor that affects the function and development of immune cells. Here, we show that recipient mice receiving AhR(-/-) T cells have improved survival and decreased acute graft versus host disease (aGvHD) in two different murine allogeneic bone marrow transplant models (BMT). We also show that CD4(+) T cells lacking AhR demonstrate reduced accumulation in secondary lymphoid tissue due to low levels of proliferation 4 days after BMT. Additionally, we found a significant increase in the quantity of peripherally induced regulatory donor T cells (pTregs) in the colon of recipients transplanted with AhR(-/-) T cells 14 days after transplant...

Neuroendocrine carcinoma of the cervix is an ultra-rare malignancy with a poor prognosis and limited treatment options. Checkpoint blockade immunotherapy has rapidly developed into an emerging standard of care for several common disease types. Interestingly, in preclinical and retrospective clinical data, radiation therapy has been demonstrated to synergize with checkpoint inhibitors. Here we report a patient with metastatic, chemotherapy-refractory neuroendocrine carcinoma who presented with partial bowel obstruction due to a large tumor burden...

Rohu (Labeo rohita), an Indian Major Carp (IMC) is an economically important aquaculture species in India. Inspite of the technological advances, infectious diseases caused by viruses, bacteria and parasites have been a major limiting factor in the development and profitability of fish farms. At present, information regarding the immune status of the Indian major carps is limited. This lack of knowledge is a major impediment for establishment of effective preventive measures against broad spectrum of infectious agents...

A key tool for the control, elimination, and eradication of Plasmodium vivax is the development of an effective vaccine. The thrombospondin-related adhesion protein (TRAP) is one of the major sporozoite antigens that plays an important role in the invasion of mosquito salivary glands and hepatocytes by sporozoites. The main goal of this study was to evaluate the naturally acquired antibodies to the P. vivax TRAP (PvTRAP) in patients from malaria-endemic areas of Iran (n=116), Afghanistan (n=50), and Pakistan (n=50)...

Southeastern states namely Georgia, Florida, and Alabama produce two-thirds of the peanuts in the United States. Thrips-transmitted Tomato spotted wilt virus (TSWV), which causes spotted wilt disease, has been a major impediment to peanut production for the past three decades. The cultivars grown in the 1980s were extremely susceptible to TSWV. Early yield losses extended to tens of millions of dollars each year (up to 100% loss in many fields). This situation led to the creation of an interdisciplinary team known as "SWAT: Spotted Wilt Action Team"...
