Oral cavity mucosal melanomas (OCMM) represent only 3% of all malignant melanomas. Surgery is the mainstay of treatments and it is often followed by adjuvant radiotherapy. The role of adjuvant immunotherapy and/or chemotherapy is still debated and to date neither treatment is routinely used. From January 1990 to January 2010, we have collected from our database data of 20 patients with a histologically proven diagnosis of OCMM. Upfront surgery, followed by adjuvant radiotherapy was performed in 16/20 (80%) patients...

The previous study evaluated the antitumor activity and the underlying mechanism of the purified polyphenols from pinecones of Pinus koraiensis (PPP-40) using a tumor-bearing S180 mice model. This study was designed to evaluate the protective effects of PPP-40 on spleen tissues of S180 mice in vivo. Pretreatment with PPP-40 (150 mg per kg BW per D) could significantly inhibit tumor growth, enhance spleen index and prevent the decline of haematological parameters of S180 mice induced by the tumor microenvironment...

Natural killer (NK) cells are traditionally considered as innate cells, but recent studies suggest that NK cells can distinguish antigens, and that memory NK cells expand and protect against viral pathogens. Limited information is available about the mechanisms involved in memory-like NK cell expansion, and their role in bacterial infections and vaccine-induced protective immune responses. In the current study, using a mouse model of tuberculosis (TB) infection, we found that interferon-gamma producing CD3-NKp46+CD27+KLRG1+ memory-like NK cells develop during Bacille Calmette-Guérin vaccination, expand, and provide protection against challenge with Mycobacterium tuberculosis (M...

Meningioma is the most common primary brain tumour in the cat. Although most of these tumours are considered to be benign based on histological characteristics, little is known regarding microenvironmental changes associated with the tumour. The characterization of the immune-cell infiltrate in human and canine meningiomas has been described; however, there are no data regarding the cat equivalent. Seventeen formalin-fixed, paraffin wax-embedded samples of feline meningioma were evaluated by light microscopy and immunohistochemistry (IHC) for expression of CD3, Pax5, Iba-1, HLA-DR, MAC387, CD163 and Ki67...

Behcet's disease is a multi‑system inflammatory disorder, and ocular Behcet's disease (OBD) is one of the most common causes of uveitis in China. A number of studies have indicated that Th17 cells, a subset of interleukin-17 (IL-17)-producing CD4+ T‑helper cells, serve important roles in the pathogenesis of OBD. Berberine (BBR) is an isoquinoline derivative alkaloid isolated from Chinese herbs, and has been used traditionally for the treatment of gastrointestinal disorders. The aim of the present study was to investigate the effect of BBR on Th17 cell proliferation and cytokine secretion, and the expression and activation of the signal transducer and activator of transcription 3 (STAT3) transcription factor in OBD in vitro...

BACKGROUND/AIM: Statins are cholesterol reducers with considerable dose-dependent effect against glioma cells. The apoptotic effect could be increased by combining statins or by adding pioglitazone (PGZ). The last one is an anti-diabetic drug, an agonist of the peroxisome proliferator-activated receptor-gamma (PPARG). We used an animal model to test the effect of such combination in vivo and we investigated the changes on immunological processes. MATERIALS AND METHODS: Thirty-three rats (F344/DuCrl) were anesthetized and glioblastoma (F98) cells were implanted stereotactically...

Ipilimumab (IPI) is a monoclonal antibody that targets the inhibitory CTLA4 receptor of T cells, enhancing T-cell-driven antitumor responses. IPI therapy in metastatic melanoma results in significant improvement in disease-free and overall survival, although after initial responses disease progression generally ensues. Identification of specific responses in tissue where melanoma tumor cells are subjected to IPI-driven immune attack may reveal mechanisms of treatment efficacy or resistance, permitting refinement of targeted therapeutic approaches...

Inflammatory responses and innate immunologic reactions play an important role in the respiratory system. Ex vivo lung perfusion (EVLP) is considered a novel method in the evaluation and reconditioning of donor lungs prior to transplantation. However, EVLP's effect on inflammatory and metabolic markers of human lung tissue is unknown.  This study investigated how the performance of EVLP on brain-dead (BD) donor lungs affects the production and release of inflammatory cytokines (IL-6, IL-8, and TNF-a), inflammatory cells and toll-like receptors (TLR) -2, 4...

Complications of allogeneic hematopoietic stem cell transplantation (HSCT) have been attributed to immune cells transferred into the patient with the graft. However, a detailed immune cell composition of the graft is usually not evaluated. In the present study, we determined the level of variation in the composition of immune cells between clinical HSCT grafts and whether this variation is associated with clinical outcome. Sizes of major immune cell populations in 50 clinical grafts from a single HSCT Centre were analyzed using flow cytometry...

The host inflammatory response plays an important role in many solid malignancies. Studies on oesophageal adenocarcinomas (EACs) point towards a beneficial role of pronounced immunoreaction, however, congruent results have yet to be obtained. We analysed 111 primary resected EAC using a tissue microarray containing three cores of the tumour centre and the periphery per case. Overall inflammation was assessed by histomorphology. Tumour infiltrating lymphocytes (TILs) were characterised by immunohistochemistry for CD3, CD8 and FoxP3, and evaluated by image analysis (Aperio ImageScope)...

T-cell-engaging immunotherapies are exciting new approaches to treat patients with acute lymphoblastic leukemia (ALL). These unique agents, which include blinatumomab, a CD3/CD19 bispecific antibody, and chimeric antigen receptor (CAR) modified T cells targeted to CD19 have shown unprecedented remission rates in the relapsed, refractory ALL setting. Cytokine release syndrome (CRS), resulting from the high magnitude of immune activation by these therapies, is the most significant treatment-related toxicity. CRS manifests with fever and malaise and can progress to life-threatening capillary leak with hypoxia and hypotension...

Inosine Acedoben Dimepranol (IAD), licensed for the treatment of cell-mediated immune deficiencies associated with viral infections, has been reported to impact a variety of immune parameters both in vitro and in vivo. Here we report the results from a clinical trial where multiple lymphocyte subsets - CD19+ B cells, CD3+ T cells, CD4+ T-helper cells, FoxP3(hi)/CD25(hi)/CD127(lo) regulatory T cells (Tregs), CD3-/CD56+ NK cells, and CD3+/CD56+ NKT cells - were, together with serum immunoglobulins and IgG subclasses, followed during 14days of IAD administration to ten healthy volunteers; these selected from 27 individuals pre-screened in vitro for their capacity to respond to IAD as gauged by increases in the percentage of Treg and/or NKT cells arising in PHA-stimulated cultures...

Autoimmune diseases arise due to the loss of immunological self-tolerance. Regulatory T cells (Tregs) are important mediators of immunologic self-tolerance. Tregs represent about 5 - 10% of the mature CD4(+) T cell subpopulation in mice and humans, with about 1 - 2% of those Tregs circulating in the peripheral blood. Induced pluripotent stem cells (iPSCs) can be differentiated into functional Tregs, which have a potential to be used for cell-based therapies of autoimmune diseases. Here, we present a method to develop antigen (Ag)-specific Tregs from iPSCs (i...

Synthetic biodegradable scaffolds such as polylactic acid coated polyglycolic acid (PLA-PGA) are especially suitable for engineering shaped cartilage such as auricle, but they induce a serious inflammatory reaction particularly in the immunologically aggressive subcutaneous site, leading to resorption of the engineered autologous cartilage. Our previous study in a rabbit model has demonstrated 2 weeks of in vitro precultivation could significantly alleviate the post-implantation inflammation induced by PLA-PGA engineered cartilaginous grafts, but reproduction of this result failed in a preclinical goat model...
