Although favorable immune responses to low-dose irradiation (LDI) have been observed in normal mice, i.e., a hormesis effect, little is known about the effects of LDI in infectious diseases. In this study, we examined the effects of LDI on mice with sepsis, a severe and often lethal hyperinflammatory response to bacteria. Female C57BL/6 mice were whole-body irradiated with 10cGy 48h before Escherichia coli infection, and survival, bacterial clearance, cytokines, and antioxidants were quantified. LDI pretreatment significantly increased survival from 46...

PURPOSE: Treatment with checkpoint inhibitors has shown durable responses in a number of solid tumors, including melanoma, lung, and renal cell carcinoma. However, most breast cancers are resistant to monotherapy with checkpoint inhibitors. Radiation therapy (RT) has been shown to have a number of immunostimulatory effects, including priming the immune system, recruiting immune cells to the tumor environment, and altering the immunosuppressive effects of the tumor microenvironment. RT therefore represents a promising adjuvant therapy to checkpoint blockade in breast cancer...

Triple negative breast cancer (TNBC) is a heterogeneous disease, not only on the molecular level, but also on the pathologic and clinical levels. It also has a distinct epidemiology. TNBCs are frequently of high histologic grade, typically more aggressive and difficult to treat than hormone receptor-positive tumors, and they are associated with a higher risk of early relapse with visceral metastasis after surgery, chemotherapy and/or radiotherapy. The lack of estrogen receptor, progesterone receptor and human epidermal growth factor receptor 2 expression precludes the use of targeted therapies in advanced stages, and the only approved systemic treatment option is chemotherapy with or without bevacizumab...

The introduction of immune checkpoint blockade into the clinical practice resulted in improvement of survival of a significant portion of melanoma patients. Consequently, predictive biomarkers of response are needed to optimize patient's stratification and the development of combination therapies. The aim of this study was to determine whether levels of soluble NKG2D ligands (MICA, MICB, ULBP1, 2 and 3; sNKG2DLs) in the serum of melanoma patients can serve as useful predictors of response to the treatment with immune checkpoint blockade...

β-glucans are one of the most abundant forms of polysaccharides known as biological response modifiers which influence host's biological response and stimulate immune system. Accordingly, this study was initiated to evaluate irradiated β-glucan as a modulator for cellular signaling growth factors involved in the pathogenesis of hepatocellular carcinoma in rats. Hepatocellular carcinoma was induced with 20 mg diethylnitrosamine/kg BW. Rats received daily by gastric gavage 65 mg irradiated β-glucan/kg BW. It was found that treatment of rats with diethylnitrosamine induced hepatic injury and caused significant increase in liver injury markers with a concomitant significant increase in both hepatic oxidative and inflammatory indices: alpha-fetoprotein, interferon gamma, and interleukin 6 in comparison with normal and irradiated β-glucan-treated groups...

Transfusion-associated graft-versus-host disease (TA-GVHD) is a life-threatening complication caused by the input of a number of immunocompetent allogeneic lymphocytes. This study focus on the photochemical effects of riboflavin excited by visible light (RB+L) treatment on human lymphocytes, to study the feasibility of using RB+L treatment to prevent adverse immune reactions caused by transfused lymphocytes. 100μM riboflavin was added to lymphocyte suspensions. After exposure to 400-580nm visible light with a total energy of 40J/mL, cells were cultured and the ability of proliferation and cytokine secretion were assayed upon stimuli...

Biofilms that contribute to the persistent bacterial infections pose serious threats to global public health, mainly due to their resistance to antibiotics penetration and escaping innate immune attacks by phagocytes. Here, we report a kind of surface-adaptive gold nanoparticles (AuNPs) exhibiting (1) a self-adaptive target to the acidic microenvironment of biofilm, (2) an enhanced photothermal ablation of methicillin-resistant Staphylococcus aureus (MRSA) biofilm under near-infrared (NIR) light irradiation, and (3) no damage to the healthy tissues around the biofilm...

OBJECTIVE: The aim of this study was to assess the impact of chemoradiation on the immune microenvironment to influence and optimally design future neoadjuvant clinical trials. SUMMARY BACKGROUND DATA: Programmed death (PD)-1 inhibitors in metastatic gastroesophageal cancer have demonstrated response rates of approximately 25% in programmed death ligand-1 (PD-L1+) tumors. Unfortunately, the majority of patients do not respond. Therefore, a rationale strategy of combining immunotherapeutic agents with chemoradiation in earlier stage esophageal cancer may prevent metastatic disease in patients...

Over the last 50 years, collaborative clinical trials have reduced the number of children dying from pediatric cancer significantly. Unfortunately, certain tumor types have remained resistant to conventional surgical, radiotherapy and chemotherapy combinations, and relapsing and/or refractory disease remains associated with dismal outcomes. Recently, renewed attention has been given to the role for immunotherapies in pediatric oncology. In fact, these combine several attractive features, including (but possibly not limited to) the specificity for cancer cells, potentially in vivo persistence and longevity, and potency against refractory disease...

OBJECTIVE The goal of this study was to investigate the impact of stereotactic radiosurgery (SRS), BRAF status, and targeted and immune-based therapies on the recurrence patterns and factors associated with overall survival (OS) among patients with melanoma brain metastasis (MBM). METHODS A total of 366 patients were treated for 1336 MBMs; a lesion-based analysis was performed on 793 SRS lesions. The BRAF status was available for 78 patients: 35 had BRAF (mut) and 43 had BRAF wild-type ( BRAF-WT) lesions. The Kaplan-Meier method evaluated unadjusted OS; cumulative incidence analysis determined the incidences of local failure (LF), distant failure, and radiation necrosis (RN), with death as a competing risk...

BACKGROUND: Immune responses are a major concern in gene therapy. Our previous studies demonstrated that platelet-targeted FVIII (2bF8) gene therapy together with in vivo drug-selection of transduced cells can rescue the bleeding diathesis and induce immune tolerance in FVIII(null) mice. OBJECTIVE: To investigate whether non-selectable 2bF8 lentiviral vector (LV) for the induction of platelet-FVIII expression is sufficient to induce immune tolerance and how immune tolerance is induced after 2bF8LV gene therapy...

Pancreatic cancer is one of the most aggressive malignancies and has a highly immunosuppressive tumour microenvironment. Immune checkpoint blockade has led to remarkable and durable objective responses in a number of malignancies and antibody-based strategies targeting programmed cell death protein 1 (PD-1) are showing promise where traditional modalities of surgery, radiotherapy, and chemotherapy have failed. In this study, we examined the clinical value of PD-1 protein expression by CD8+ peripheral T lymphocytes or tumour-infiltrating T lymphocytes (TILs) in pancreatic ductal adenocarcinoma (PDAC)...

As the overall survival of patients with lung cancer continues to increase, more cancer survivors are faced with the risk of developing treatment-related cardiovascular toxicities. The increased knowledge of the molecular biology of non-small cell lung cancer has led to new and more personalized treatments. Nevertheless, the usual chemotherapy schemes and radiation therapy induce cardiac toxicities that are frequently underappreciated or go unnoticed. Up to date, the majority of cardiotoxicity studies have been focused in breast cancer, but new treatments in lung cancer patients, such as immune checkpoint-blocking antibodies or tyrosine kinase inhibitors, may also exert these cardiac toxic effects and therefore demand of the close collaboration of oncologists and cardiologists, in order to be addressed...

The management of thymic tumours is a paradigm of multidisciplinary collaboration. Chemotherapy may be administered part of curative-intent sequential strategy integrating subsequent surgery or radiotherapy, or as an exclusive treatment if local treatment is not achievable. Recurrences of thymic epithelial tumors should be managed according to the same strategy as newly diagnosed tumors. Given the limited activity of cytotoxic agents in the advanced, refractory setting, novel and innovative agents are needed...

Oncolytic viruses and radiotherapy represent two diverse areas of cancer therapy, utilizing quite different treatment modalities and with non-overlapping cytotoxicity profiles. It is, therefore, an intriguing possibility to consider that oncolytic ("cancer-killing") viruses may act as cancer-selective radiosensitizers, enhancing the therapeutic consequences of radiation treatment on tumors while exerting minimal effects on normal tissue. There is a solid mechanistic basis for this potential synergy, with many viruses having developed strategies to inhibit cellular DNA repair pathways in order to protect themselves, during genome replication, from unwanted interference by cell processes that are normally triggered by DNA damage...

Brain metastases (BM) affect approximately a third of all cancer patients with systemic disease. Treatment options include surgery, whole-brain radiotherapy, or stereotactic radiosurgery (SRS) while chemotherapy has only limited activity. In cases where patients undergo resection before irradiation, intraoperative radiotherapy (IORT) to the tumor bed may be an alternative modality, which would eliminate the repopulation of residual tumor cells between surgery and postoperative radiotherapy. Accumulating evidence has shown that high single doses of ionizing radiation can be highly efficient in eliciting a broad spectrum of local, regional, and systemic tumor-directed immune reactions...
