Celiac disease (CD) treatment requires a gluten-free diet (GFD), although alternative approaches have been proposed. Modification of gliadin peptides using microbial transglutaminase (mTG) inhibits their ability to induce immune response in vitro. Our aim was to evaluate the safety of mTG-modified wheat flour ingestion in CD patients. Twenty-one CD patients in remission were randomized to receive mTG-modified (n=11) or unmodified (n=10) wheat flour rusks, in double-blind fashion. Monthly, patients completed a symptom questionnaire...

REVIEW
Qiaohong Wang, Xia Wu
PD-1/PD-L1 blockade appears to be a very promising immunotherapy with significant clinical benefits and durable responses in multiple tumor types. However, the effectual clinical benefits of PD-1/PD-L1 blockade are hampered by a high rate of primary resistance, where patients do not respond to PD-1/PD-L1 blockade initially. And more distressingly, most patients eventually develop acquired resistance after an initial response to PD-1/PD-L1 blockade. The mechanisms underlying primary and acquired resistance to PD-1/PD-L1 blockade have remained ambiguous...

Acute graft-versus-host disease (aGVHD) is a major complication following transplantation, limiting the success of this therapy. Chitinase 3-like-1 (CHI3L1), a member of the glycosyl hydrolase 18 family, plays a critical role in bacterial infections, allergic disease and a variety of malignancies. Here, we investigated whether CHI3L1 could affect the pathogenesis of aGVHD in a mouse allo-HCT model. In this study, we show that CHI3L1 deficiency in donor T cells increased the severity of aGVHD through enhancing systemic and local inflammation...

Acute lung injury (ALI) is a serious disease with high morbidity and mortality rate. Although there are effective strategies for treatment of ALI; a widely accepted specific pharmacotherapy has not yet established. Zerumbone, the major active phytochemical compound from Zingiber zerumbet Smith, exhibits various beneficial biological and pharmacological activities, such as antioxidation, anti-inflammation, immunomodulation, and anti-cancer. We aimed to study the potential protective effects and mechanisms of zerumbone in mouse model of lipopolysaccharide (LPS)-induced ALI...

This study investigated whether GV1001 may be useful for treating rheumatoid arthritis (RA). Two collagen-induced arthritis (CIA) experiments showed that therapeutic, but not preventive, GV1001 treatment reduced the severity of joint inflammation in CIA. The third CIA experiment indicated that, compared to vehicle treatment, therapeutic GV1001 treatment was associated with a significantly smaller area under the curve for the overall clinical joint score over the 98day observation period (p<0.05). GV1001 treatment was also associated with lower Day 98 serum IL-6 levels (p<0...

Exposure to ionizing radiation (IR) often reduce the helper T (Th) 1 like function, resulting in a Th1/Th2 imbalance, which could affect the efficacy of cancer radiotherapy. As the most potent antigen presenting cells, dendritic cells (DC) can be divided into several subsets with specialized function. However, there is no literature covering the changes of DC subsets and their roles in immune regulation in response to IR. In the present study, we were aimed to investigate the changes of DC subsets after IR and its relationship with Th1/Th2 immunity...

Emerging evidence suggests that microRNAs (miRNAs) play a critical role in the pathogenesis of neuropathic pain. However, the exact role of miRNAs in regulating neuropathic pain remains largely unknown. In this study, we aimed to investigate the potential role of miR-93 in a rat model of neuropathic pain induced by chronic constriction sciatic nerve injury (CCI). We found a significant decrease of miR-93 in the spinal cord of CCI rats compared with sham rats. Overexpression of miR-93 significantly alleviated neuropathic pain development and reduced inflammatory cytokine expression, including interleukin (IL)-1β, tumor necrosis factor (TNF)-α, and IL-6 in CCI rats...

Usnic acid (UA) can be found in certain lichen species. Growing evidence suggests that UA possesses antitumoral, antioxidative and anti-inflammatory activities. Bleomycin (BLM) is widely used in the treatment of malignant ascites, however, it unexpectedly causes pulmonary fibrosis (PF). Researches show that excessive inflammatory response and oxidative stress in lung tissue is conspicuous causes of BLM-induced PF. Here we investigated mechanism underlying the effect-enhancing and toxicity-reducing activity of UA on H22-bearing mice treated with BLM...

BACKGROUND: Interleukin-23 (IL-23) is required for T helper 17 (Th17) cell responses and IL-17 production in hepatitis B virus infection. A previous study showed that the IL-23/IL-17 axis aggravates immune injury in patients with chronic hepatitis B virus infection. However, the role of IL-23 in acute liver injury remains unclear. OBJECTIVE: The purpose of this study was to determine the role of the inflammatory cytokine IL-23 in lipopolysaccharide/d-galactosamine (LPS/GalN)-induced acute liver injury in mice...

Repeated airway inflammation and unremitting remodeling provoke irreversible pulmonary dysfunction and resistance to current drugs in patients with chronic bronchial asthma. Interleukin (IL)-13 and IL-25 play an important role in airway inflammation and remodeling in asthma. We aimed to investigate whether co-inhibiting IL-13 and IL-25 can effectively down-regulate allergen-induced airway inflammation and remodeling in mice. Mice with asthma induced by chronic exposure to ovalbumin (OVA) were given soluble IL-13 receptor α2 (sIL-13R) or soluble IL-25 receptor (sIL-25R) protein alone and in combination to neutralize the bioactivity of IL-13 and IL-25, and relevant airway inflammation and remodeling experiments were performed...

To evaluate the hepatoprotective effects and potential mechanisms of paeonol (Pae) against acute liver failure (ALF) induced by lipopolysaccharide (LPS)/d-galactosamine (d-GalN) in mice, we examined anti-oxidative, anti-inflammatory and anti-apoptotic activities of Pae. We found that Pae pretreatment markedly reduced the activities of alanine transaminase and aspartate transaminase as well as the histopathological changes induced by LPS/d-GalN. Catalase, glutathione and superoxide dismutase activities increased and reactive oxygen species activity decreased after Pae treatment compared with LPS/d-GalN treatment...

The tumor microenvironment (TME) is established and maintained through complex interactions between tumor cells and host stromal elements. Therefore, therapies that target multiple cellular components of the tumor may be most effective. Sorafenib, a multi-kinase inhibitor, alters signaling pathways in both tumor cells and host stromal cells. Thus, we explored the potential immune-modulating effects of sorafenib in a murine HER-2-(neu) overexpressing breast tumor model alone and in combination with a HER-2 targeted granulocyte-macrophage colony-stimulating factor (GM-CSF)-secreting vaccine (3T3neuGM)...

Carotid atherosclerosis (AS) is an inflammatory process and is the primary pathogenesis of cerebrovascular disease. Many factors are responsible for development of atherosclerosis such as inflammation and autophagy. It is reported that microRNAs (miRNAs) could regulate the development of atherosclerosis through targeting autophagy-related genes. Many studies have demonstrated that miRNA-155 could regulate autophagy in macrophages or tumor cells. However, the role of miRNA-155 on autophagy in carotid plaques is not yet known...

Th17 cells have been categorized as a new lineage of CD4+ T cells, and played a crucial role in the pathogenesis of numerous autoimmune disorders. Type 4 metabotropic glutamate receptor (mGluR4), a member of group III mGluRs, recently has been found to be expressed in many types of immune cells and mediate adaptive immunity. Curcumin has been shown to exhibit potent anti-inflammatory, antimutagenic and anticarcinogenic properties. For the past few years, it has gradually been regarded as an pluripotent immunomodulatory agent that can regulate the activation of immune cells...
