Glioblastoma, one of the most aggressive primary brain tumors, is characterized by highly immunosuppressive microenvironment. This contributes to glioblastoma resistance to standard treatment modalities and allows tumor growth and recurrence. Several immune-targeted approaches have been recently developed and are currently under preclinical and clinical investigation. Oncolytic viruses, including the autonomous protoparvovirus H-1 (H-1PV), show great promise as novel immunotherapeutic tools. In a first phase I/IIa clinical trial (ParvOryx01), H-1PV was safe and well tolerated when locally or systemically administered to recurrent glioblastoma patients...

Soluble CD52 is a small glycoprotein that suppresses T-cell activation, but its effect on innate immune cell function is unknown. Here we demonstrate that soluble CD52 inhibits Toll-like receptor and tumor necrosis factor receptor signaling to limit activation of NF-κB and thereby suppress the production of inflammatory cytokines by macrophages, monocytes and dendritic cells. At higher concentrations, soluble CD52 depletes the short-lived pro-survival protein MCL-1, contributing to activation of the BH3-only proteins BAX and BAK to cause intrinsic apoptotic cell death...

The calcium-dependent protein kinase OsCPK4 has been demonstrated to play important roles in salt and drought tolerance, plant growth and development in rice. However, little is known on molecular mechanisms underlying OsCPK4 function in rice immunity. In this study, we demonstrated that the generation of oxidative burst and pathogenesis-related gene expression triggered by microbe-associated molecular patterns (MAMPs) were significantly enhanced in the oscpk4 mutants. These mutant lines are more resistant to bacterial blight and fungal blast diseases than the wild-type plants, indicating that OsCPK4 negatively regulates innate immunity in rice...

Previously we had developed a triple gene mutant of M. tuberculosis (MtbΔmms) harbouring disruption in three genes namely mptpA, mptpB and sapM Though vaccination with MtbΔmms strain induced protection in the lungs of guinea pigs, the mutant strain failed to control the hematogenous spread of the challenge strain to the spleen. Additionally, inoculation with MtbΔmms resulted in some pathological damage to the spleens in the early phase of infection. In order to generate a strain that overcomes the pathology caused by MtbΔmms in spleen of guinea pigs and controls dissemination of the challenge strain, MtbΔmms was genetically modified by disrupting bioA gene to generate MtbΔmmsb strain...

Pancreatic cancer (PC) is the fourth leading cause of cancer-related deaths in the U.S., claiming approximately 45,000 lives every year. Much like other solid tumors, PC evades the host immune surveillance by manipulating immune cells to establish an immunosuppressive tumor microenvironment (TME). Therefore, targeting and reinstating patient's immune system could serve as a powerful therapeutic tool. Indeed, immunotherapy has emerged in recent years as a potential adjunct treatment for solid tumors including PC...

As potent antigen-presenting cells, dendritic cells (DCs) comprise the most heterogeneous cell population with significant cellular phenotypic and functional plasticity. They form a sentinel network to modulate immune responses, since intrinsic cellular mechanisms and complex external, environmental signals endow DCs with the distinct capacity to induce protective immunity or tolerance to self. Interactions between DCs and other cells of the immune system mediate this response. This interactive response depends on DC maturation status and subtype, as well as the microenvironment of the tissue location and DC-intrinsic regulators...

OBJECTIVE: Gestational diabetes Mellitus has been considered an inflammatory disease involving different cells and mediators in its development. The role of innate immune cells in GDM physiopathology remains unclear, therefore this study was conducted to assess monocyte profile in GDM patients. DESIGN: This was a case-control study including 20 glucose-tolerant pregnant women (controls) and 18 GDM patients. METHODS: Flow cytometry was used to assess peripheral blood monocytes subsets (classical, intermediate, non-classical), the expression of TLR4 and CCR2 chemokine receptor (CD192) and cytokines (TNFA, IL6, IL10) secretion by monocytes subsets...

Chronic plaque psoriasis is an immune-mediated inflammatory skin disease that is strongly associated with the clinical features of the metabolic syndrome (MetS), including abdominal obesity, hypertension, atherogenic dyslipidemia, type 2 diabetes, insulin resistance, and nonalcoholic fatty liver disease. The strength of these associations has been repeatedly confirmed by several observational studies. In particular, the prevalence of MetS in patients with psoriasis ranges from 20% to 50%, with a risk of having MetS is at least double in psoriatic patients compared with nonpsoriatic control individuals...

Interactions between the host and its microbiota are of mutual benefit and promote health. Complex molecular pathways underlie this dialog, but the identity of microbe-derived molecules that mediate the mutualistic state remains elusive. Helicobacter hepaticus is a member of the mouse intestinal microbiota that is tolerated by the host. In the absence of an intact IL-10 signaling, H. hepaticus induces an IL-23-driven inflammatory response in the intestine. Here we investigate the interactions between H. hepaticus and host immune cells that may promote mutualism, and the microbe-derived molecule(s) involved...

In the absence of IL-10, Helicobacter hepaticus (Hh) induces colitis. In this issue of Cell Host & Microbe, Danne et al. (2017) report that Hh produces a polysaccharide that induces an anti-inflammatory response in macrophages, providing a potential clue as to why this bacterium is normally tolerated by the immune system.

Legumes form endosymbiotic interaction with host compatible rhizobia, resulting in the development of nitrogen-fixing root nodules. Within symbiotic nodules, rhizobia are intracellularly accommodated in plant-derived membrane compartments, termed symbiosomes. In mature nodule, the massively colonized cells tolerate the existence of rhizobia without manifestation of visible defense responses, indicating the suppression of plant immunity in the nodule in the favur of the symbiotic partner. Medicago truncatulaDNF2 (defective in nitrogen fixation 2) and NAD1 (nodules with activated defense 1) genes are essential for the control of plant defense during the colonization of the nitrogen-fixing nodule and are required for bacteroid persistence...

The method of cyanoacrylate-mediated obliteration of subcutaneous veins is known to be an alternative to thermal endovascular obliteration and eliminates the need for tumescent anaesthesia. This technique is based on glue-induced damage to the venous intima, followed by immune response according to the delayed-type hypersensitivity principle. The authors report herein their first experience with using cyanoacrylate-mediated embolization in treatment of patients presenting with varicose veins. The operation was carried out using the VenaSeal closure system (Medtronic)...

Chemotherapy prolongs overall survival (OS) in esophageal (EC) and gastric cancer (GC). Unsatisfactory results of systemic therapy initiated a search for new treatment options. In metastatic disease, a number of targeted drugs were tested; however, several phase III studies assessing receptor tyrosin kinase-related signaling pathways, such as EGFR, MET/HGF or mTOR, failed. Trastuzumab remains the only targeted drug with a known molecular predictor, which extended the OS in metastatic gastric adenocarcinoma and adenocarcinoma of esophago-gastric junction...

The advent of immunotherapy has changed our concept of how to manage metastatic disease. With the exception of relatively rare tumors, the treatment of metastatic cancer is still considered as palliative, and in systemic treatment immunotherapy is often selected, considering better tolerance. Immunotherapy opens the perspective of a long-term, possibly durable, response, and, in contrast to other approaches to targeted therapy, is active across a spectrum of tumors. Combined regimens that increase the efficacy, given the context, are thus of importance...

Urothelial carcinoma is the most common urological malignancy. Nonspecific immunotherapy using the Bacillus Calmette-Guerin vaccine has long been the mainstay for the treatment of high-risk superficial bladder carcinoma in an adjuvant setting after transurethral endoscopic resection. In metastatic disease, cisplatin-based chemotherapy remains the main therapeutic modality. In Europe, the standard second-line chemotherapy for patients with cisplatin-refractory tumours is vinflunine. Other systemic treatments with a lower level of evidence include paclitaxel and docetaxel...

Tumor antigen alpha-fetoprotein (AFP) can promote immune tolerance toward tumor cells by inducing regulatory functions of the immune system. The purpose of this study was to characterize the effects of AFP on dendritic cells (DC) in their antitumor immune response stimulation and subsequent immune tolerance toward tumor cells. Monocytes were cultured in medium with GM-CSF and IL-4 and incubated for 6 days to generate immature DC (imDC). AFP was added into the treatment group at the beginning of the monocyte-derived DC culture...

Background: Macrophage migration inhibitory factor (MIF) is a key proinflammatory mediator. It plays a vital role in immune response against the oral disease. MIF is a regulator of innate immunity, and bacterial antigens can stimulate serum level of this protein. In experimental gingivitis, the expression level of MIF increases and this increment positively correlates with oral plaque index. The single nucleotide polymorphisms in the gene encoding the MIF protein can control the function of MIF...

Langerhans cells (LCs) reside in the epidermis as a dense network of immune system sentinels. These cells determine the appropriate adaptive immune response (inflammation or tolerance) by interpreting the microenvironmental context in which they encounter foreign substances. In a normal physiological, "non-dangerous" situation, LCs coordinate a continuous state of immune tolerance, preventing unnecessary and harmful immune activation. Conversely, when they sense a danger signal, for example during infection or when the physical integrity of skin has been compromised as a result of a trauma, they instruct T lymphocytes of the adaptive immune system to mount efficient effector responses...

Mesenchymal stem cells (MSCs) have been demonstrated to be anti-inflammatory against various immune disorders through several factors, including indoleamine 2,3-dioxygenase (IDO) and TNF-stimulated gene 6 (TSG-6). However, little is known about the necessity for both of these key immunosuppressive factors. Here we employed the mouse lipopolysaccharide (LPS)-induced acute lung injury (ALI) model, and found that IDO is necessary to achieve the effect of human umbilical cord-derived MSC (hUC-MSC)-based treatment on ALI...
