REVIEW
Daniel E Meyers, Amanda A Wang, Chandini M Thirukkumaran, Don G Morris
Oncolytic viruses (OV) represent a promising strategy to augment the spectrum of cancer therapeutics. For efficacy, they rely on two general mechanisms: tumor-specific infection/cell-killing, followed by subsequent activation of the host's adaptive immune response. Numerous OV genera have been utilized in clinical trials, ultimately culminating in the 2015 Food and Drug Administration approval of a genetically engineered herpes virus, Talminogene laherparepvec (T-VEC). It is generally accepted that OV as monotherapy have only modest clinical efficacy...

Vaccination of infants with bacillus Calmette-Guérin (BCG) activates both the innate and adaptive arms of the immune response. The antimycobacterial effects of these responses most likely account for the ability of BCG to protect against childhood forms of tuberculosis (TB). There is also evidence for a heterologous protective effect of BCG vaccination against TB-unrelated mortality in low birth weight infants. A possible mechanism of action of this effect, the induction of trained innate immunity, has been demonstrated when cells from BCG-vaccinated adults are restimulated in vitro with non-related microbial stimuli...

Evidence for the effect of granulocyte colony stimulating factor (G-CSF) on infertile women undergoing in vitro fertilization (IVF) remains inconsistent. This study aimed to evaluate the effectiveness of G-CSF on infertile women undergoing IVF. PubMed and EMBASE databases were searched before August 2016. Comparing the transvaginal perfusion of G-CSF and placebo or no treatment, the available studies were considered. The pooled risk ratio (RR) with 95% confidence intervals (CIs) was used in the analysis and six studies were included...

Plerixafor is a CXC chemokine receptor (CXCR4) antagonist that mobilizes stem cells in the peripheral blood. It is indicated (in combination with granulocyte-colony stimulating factor [G-CSF]) to enhance the harvest of adequate quantities of cluster differentiation (CD) 34+ cells for autologous transplantation in patients with lymphoma or multiple myeloma whose cells mobilize poorly. Strategies for use include delayed re-mobilization after a failed mobilization attempt with G-CSF, and rescue or pre-emptive mobilization in patients in whom mobilization with G-CSF is likely to fail...

Porphyromonas gulae is an anaerobic, Gram-negative coccobacillus that has been associated with periodontal disease in companion animals. The aims of this study were to analyse the ligation of pattern recognition receptors by P. gulae and the subsequent activation of macrophages. Exposure of HEK cells transfected with Toll-like receptors or NOD-like receptors to P. gulae resulted in the ligation of TLR2, TLR4 and NOD2. The effect of this engagement of receptors was investigated by measuring the synthesis of nitric oxide, CD86 expression and inflammatory cytokine production using wild type, TLR2-/- and TLR4-/- macrophages...

As potential treatments for C9ORF72-associated amyotrophic lateral sclerosis (c9ALS) approach clinical trials, the identification of prognostic biomarkers for c9ALS becomes a priority. We show that levels of phosphorylated neurofilament heavy chain (pNFH) in cerebrospinal fluid (CSF) predict disease status and survival in c9ALS patients, and are largely stable over time. Moreover, c9ALS patients exhibit higher pNFH levels, more rapid disease progression, and shorter survival after disease onset than ALS patients without C9ORF72 expansions...

We report a rare case of squamous cell carcinoma (SCC) in bladder diverticulum producing granulocyte colony stimulating factor (G-CSF). A 59-year-old man complaining of hematuria and right hip pain was admitted with a large cancer in the bladder diverticulum. His laboratory data showed leukocytosis of 20,100/ μ l (neutrophils : 92%) with an elevated G-CSF of 76. 6 pg/ml in the peripheral blood. After neoadjuvant chemotherapy (gemcitabine and cisplatin), radical cystectomy was performed to normalize serum leukocytosis and G-CSF...

T cells are considered pivotal in the pathology of multiple sclerosis (MS), but their function and antigen specificity are unknown. To unravel the role of T cells in MS pathology, we performed a comprehensive analysis on T cells recovered from paired blood, cerebrospinal fluid (CSF), normal-appearing white matter (NAWM) and white matter lesions (WML) from 27 MS patients with advanced disease shortly after death. The differentiation status of T cells in these compartments was determined by ex vivo flow cytometry and immunohistochemistry...

In this study, we showed that G-CSF mobilization increased the frequency of T cells, specifically CD3+CD4+ T cells. G-CSF mobilization decreased the secretion of inflammatory cytokines of CD4+ T cells through the LFA-1/ICAM-1 signaling pathway, whereas it did not alter the TH1/TH2 ratio. We found that G-CSF mobilization inhibited LFA-1-mediated CD4+ T cell polarization and motility. In vitro, G-CSF stimulation also attenuated the polarization and adhesiveness of CD4+ T cells through the LFA-1/ICAM-1 interaction...

BACKGROUND: Recombinant human granulocyte-colony stimulating factor (G-CSF, filgrastim) is used primarily to reduce incidence and duration of severe neutropenia and its associated complications in cancer patients that have received a chemotherapy regimen. The pegylated form of filgrastim, "pegfilgrastim", is a long-acting form that requires only a once-per-cycle administration for the management of chemotherapy-induced neutropenia. Apobiologix, a division of ApoPharma USA, Inc., and Intas Pharmaceuticals Limited have co-developed a proposed pegfilgrastim biosimilar to US-licensed pegfilgrastim...

Major depressive disorder (MDD) in the elderly is a risk factor for dementia, but the precise biological basis remains unknown, hampering the search for novel biomarkers and treatments. In this study, we performed metabolomics analysis of cerebrospinal fluid (CSF) from cognitively intact elderly patients (N = 28) with MDD and age- and gender-matched healthy controls (N = 18). The CSF levels of 177 substances were measured, while 288 substances were below the detection limit. Only ascorbic acid was significantly different, with higher levels in the MDD group at baseline...

For high-risk breast cancer patients with positive axillary lymph nodes, dose-dense every-two-week epirubicin/cyclophosphamide-paclitaxel (ddEC-P) regimen is the optimal postoperative adjuvant therapy. However, this regimen is limited by the grade 3/4 neutropenia and febrile neutropenia (FN). There is an urgent need to explore the efficacy, safety and proper dosage of PEGylated granulocyte colony-stimulating factor (PEG-G-CSF) as support for ddEC-P in Chinese breast cancer patients with positive axillary lymph nodes...

Sweet's syndrome is a neutrophilic dermatosis characterized by an abrupt onset of painful erythematous lesions showing neutrophilic infiltrates in the dermis. Fever and an elevated neutrophil level are generally observed. Sweet's syndrome may be idiopathic, malignancy-associated, or drug-induced (mainly involving granulocyte colony-stimulating factor (G-CSF) administration). Although systemic corticosteroids are usually effective, the symptoms of Sweet's syndrome recur in some refractory cases. Herein, we report a case of a 55-year-old Japanese woman with recurrent symptoms of fever (>39°C) and painful erythematous lesions on her four extremities, trunk, and neck...

Pancreatic ductal adenocarcinoma (PDAC) after complete surgical resection is often followed by distant metastatic relapse for reasons that remain unclear. In this study, we investigated how the immune response at secondary sites affects tumor spread in murine models of metastatic PDAC. Early metastases were associated with dense networks of CD11b(+)CD11c(+)MHC-II(+)CD24(+)CD64(low)F4/80(low) dendritic cells (DC), which developed from monocytes in response to tumor-released GM-CSF. These cells uniquely expressed MGL2 and PD-L2 in the metastatic microenvironment and preferentially induced the expansion of T regulatory cells (Treg) in vitro and in vivo...

BACKGROUND: The phenolic substance resveratrol (RES) is a plant metabolite known to modulate numerous physiological functions and to exert beneficial effects as a cancer-chemopreventing agent and on neurological, hepatic, and cardiovascular systems. Since the compound affects the lifespan of yeast and flies it might be an anti-aging substance. Mechanistically, RES is involved in down regulating the inflammatory response. The pleiotropic effects of RES in cells of the immune and endothelial system were examined in this study...

Ectromelia virus (ECTV) is an orthopoxvirus responsible for mousepox, a lethal disease of certain strains of mice that is similar to smallpox in humans, caused by variola virus (VARV). ECTV, similar to VARV, exhibits a narrow host range and has co-evolved with its natural host. Consequently, ECTV employs sophisticated and host-specific strategies to control the immune cells that are important for induction of antiviral immune response. In the present study we investigated the influence of ECTV infection on immune functions of murine GM-CSF-derived bone marrow cells (GM-BM), comprised of conventional dendritic cells (cDCs) and macrophages...

BACKGROUND: Valproic acid (VPA) has been widely used in Chinese patients after craniotomy. Many studies have focused on the influencing factors of VPA serum concentration, but conclusions are sometimes paradoxical. Furthermore, the concentration of VPA in the cerebrospinal fluid (CSF) has been rarely reported. In the present study, VPA CSF concentrations were measured and the potential factors influencing serum concentration and CSF distribution of VPA were investigated. In addition, the functional relationship between serum and CSF concentration was explored...
