Therapy that directly targets apoptosis and/or inflammation could be highly effective for the treatment of cancer. Murraya koenigii is an edible herb that has been traditionally used for cancer treatment as well as inflammation. Here, we describe that girinimbine, a carbazole alkaloid isolated from M. koenigii, induced apoptosis and inhibited inflammation in vitro as well as in vivo. Induction of apoptosis in human colon cancer cells (HT-29) by girinimbine revealed decreased cell viability in HT-29, whereas there was no cytotoxic effect on normal colon cells...

The c-Rel transcription factor is a unique member of the nuclear factor (NF)-κB family that has a role in curtailing the proliferation, differentiation, cytokine production, and overall activity of B- and T-cells. In addition, c-Rel is a key regulator of apoptosis in that it influences the expression of anti-apoptotic genes such as Bcl-2 and Bcl-xL; conversely, inhibition of c-Rel increases cell apoptosis. To better understand the relationship between c-Rel expression and effects on B- and T-cell expansion, the current study evaluated c-Rel expression in cord blood mononuclear cells...

BACKGROUND CONTEXT: Degenerative Disc Disease (DDD) remains without an effective therapy and presents a costly burden to society. PURPOSE: Based upon prior reports concerning the effects of notochordal cell conditioned medium (NCCM) upon disc cells, we performed a proof of principle study to determine whether NCCM could reduce cytotoxic stress induced apoptosis in human disc nucleus pulpous (NP) cells. STUDY DESIGN/SETTING: 'in vitro' fundamental/basic science study METHODS: NP cells derived from 15 patients undergoing spinal surgery were treated with interleukin 1β (IL-1β) and Fas ligand (FasL) or etoposide in the presence of NCCM...

Interferon α (IFN-α) exerts potent antiviral, immunomodulatory, and antiproliferative activity and have proven clinical utility in chronic hepatitis B and C virus infections. However, repeated IFN-α administration induces neutralizing antibodies (NAb) against the therapeutic in a significant number of patients. Associations between IFN-α immunogenicity and loss of efficacy have been described. So as to improve the invivo biological efficacy of IFN-α, a long lasting hyperglycosylated protein (4N-IFN) derived from IFN-α2b wild type (WT-IFN) was developed...

BACKGROUND: Renal cell cancer (RCC) is a prevalent and lethal disease. At time of diagnosis, most patients present with localized disease. For these patients, the standard of care includes nephrectomy with close monitoring thereafter. While many patients will be cured, 5-year recurrence rates range from 30% to 60%. Furthermore, nearly one-third of patients present with metastatic disease at time of diagnosis. Metastatic disease is rarely curable and typically lethal. Cytotoxic chemotherapy and radiation alone are incapable of controlling the disease...

Alongside the rapid growth in aging populations worldwide, prevention and therapy for age-related memory decline and dementia are in great demand to maintain a long healthy life. Here we found that iso-α-acids, hop-derived bitter compounds in beer, enhance microglial phagocytosis and suppress inflammation via activation of the peroxisome proliferator-activated receptor (PPAR-γ). In normal mice, oral administration of iso-α-acids led to a significant increase both in CD11b and CD206 double-positive anti-inflammatory type microglia (P<0...

With a steady increase in its incidence and lack of curative treatment, type 1 diabetes (T1D) has emerged as a major health problem worldwide. To design novel effective therapies, there is a pressing need to identify regulatory targets controlling the balance of autoreactive to regulatory-T-cells (Tregs). We previously showed that the inhibition of the γ-subunit of the Phosphoinositide-3-kinase (PI3K), significantly suppress autoimmune-diabetes. To further delineate the mechanisms and the selectivity of specific immune modulation by PI3Kγ-inhibition, we developed a new NOD mouse model of T1D lacking the γ-subunit of PI3K...

Human immunodeficiency virus-associated neurological disorders (HANDs) affect the majority of AIDS patients and are a significant problem among HIV-1-infected individuals who live longer because of combined anti-retroviral therapies. HIV-1 utilizes a number of viral proteins and subsequent cytokine inductions to unleash its toxicity on neurons. Among HIV-1 viral proteins, Nef is a small protein expressed abundantly in astrocytes of HIV-1-infected brains and has been suggested to have a role in the pathogenesis of HAND...

Patients with B cell hematologic malignancies who progress through first or second line chemotherapy have a poor prognosis. Early clinical trials with autologous anti-CD19 chimeric antigen receptor (CAR) T cells have demonstrated promising results for patients who have relapsed or refractory disease. Lymphodepleting conditioning regimens including cyclophosphamide, fludarabine, pentostatin, bendamustine, interleukin-2, and total body irradiation are often administered prior to infusion of CAR T cells, allowing for greater T cell expansion...

Surgical resection is a standard component of treatment in the clinical management of patients with glioblastoma multiforme (GBM). However, experimental therapies are rarely investigated in the context of tumor debulking in preclinical models. Here, a surgical debulking GBM xenograft model was developed in nude rats, and was used in combination with CD47 blocking immunotherapy, a novel treatment strategy that triggers phagocytosis of tumor cells by macrophages in diverse cancer types including GBM. Orthotopic patient-derived xenograft tumors expressing CD47 were resected at 4 weeks after implantation and immediately thereafter treated with anti-CD47 or control antibodies injected into the cavity...

PURPOSE: Despite the vast number of clinical trials conducted so far, Dendritic cell (DC)-based cancer vaccines have mostly shown unsatisfactory results. Factors and manufacturing procedures essential for these therapeutics to induce effective anti-tumor immune responses have yet to be fully characterized. We here aimed to identify DC markers correlating with clinical and immunological response in a prostate carcinoma vaccination regimen. EXPERIMENTAL DESIGN: We performed an extensive characterization of DCs used to vaccinate 18 prostate carcinoma patients enrolled in a pilot trial of TCR gamma alternate reading frame protein (TARP) peptide vaccination (NCT00908258)...

BACKGROUND: Toll-like receptor (TLR)-mediated inflammation may contribute to neonatal sepsis, for which pentoxifylline (PTX), a phosphodiesterase inhibitor that raises intracellular cAMP, is a candidate adjunctive therapy. We characterized the anti-inflammatory effects of PTX towards TLR-mediated production of inflammatory (TNF, IL-1ß) and pro-resolution (IL-6, IL- 10) cytokines in human newborn and adult blood. METHODS: Newborn cord and adult blood were treated with PTX (50 - 400 μM) before, during or after stimulation with LPS (TLR4 agonist), R848 (TLR7/8 agonist) or LPS/ATP (inflammasome activation)...

Islet cell transplantation has limited effectiveness because of an instant blood-mediated inflammatory reaction (IBMIR) that occurs immediately after cell infusion and leads to dramatic β cell death. In intraportal islet transplantation models using mouse and human islets, we demonstrated that alpha-1 antitrypsin (AAT, Prolastin-C), a serine protease inhibitor used for the treatment of AAT deficiency, inhibits IBMIR and cytokine-induced inflammation in islets. In mice, more diabetic recipients reached normoglycemia after intraportal islet transplantation when they were treated with AAT compared to mice treated with saline...

Current treatment strategies for inflammatory bowel diseases (IBDs) are associated with a lower efficacy and with several side effects that strongly affect the quality of life of IBD patients. Consequently, the development of new therapies, combining efficacy and safety is an important goal in the field of intestinal inflammation. In this context, evidence supports that polyphenols can be promising candidates due to their ability to modulate intracellular inflammatory signalling cascades. Luteolin, a naturally occurring flavonoid, exhibits anti-inflammatory properties in several models of inflammation...

Adaptive immunity in intestinal inflammation may play a key role in the pathogenesis of Crohn's disease. In particular, interleukin (IL)-23 may be a key mediator in chronic intestinal inflammation by inducing the differentiation of naïve CD4+ T cells into Th17, with the production of several pro-inflammatory cytokines. Furthermore, IL-23 induces interferon-γ (IFN- γ) production from activated T cells, a critical cytokine in innate and adaptive immunity against infections. Areas covered: We aim to review the available data from literature regarding the role of IL-23, with a more specific focus on the recent progresses in the therapeutic modulation of this cytokine...

BACKGROUND: Biologic drugs are novel therapeutic agents with demonstrated effectiveness in the management of a variety of chronic inflammatory disorders. Unmet needs in the treatment of chronic pain have led physicians to utilize a similar approach to patients suffering from conditions not characterized by systemic inflammation such as osteoarthritis (OA). The aim of this review is to discuss the current knowledge on the use of commonly used biologic agents [i.e., anti-tumor necrosis factor alpha (anti-TNF alpha) and anti-nerve growth factor (anti-NGF)] for the management of OA...
