OBJECTIVE: Modern image-guided small animal irradiators like the Xstrahl Small Animal Radiation Research Platform (SARRP) are designed with ultrathin 0.15 mm Cu filters, which compared with more heavily filtrated traditional cabinet-style biological irradiators,...
PURPOSE: To evaluate the acute changes in leukocyte populations after focal irradiation and to assess the role of Interleukin-6 (IL6) in acute and late radiation injury. METHODS AND MATERIALS: Mice were surgically implanted with a radiopaque marker on the surface of...
OBJECTIVES: Small animal radiotherapy research platforms such as XStrahl's SARRP enable more precise irradiation of tumours and normal tissues in preclinical models of cancer. Using an orthotopic G7 glioblastoma (GBM) xenograft model we studied the impact of four...
There have been a growing number of studies combining radiotherapy with immunotherapy to enhance both local and metastatic tumor cell kill leveraging the immune-mediated abscopal effect. This abscopal effect can enable the killing of metastatic cells, distant from the...
As the population ages, more elderly patients require radiotherapy-based treatment for their pelvic malignancies, including muscle-invasive bladder cancer, as they are unfit for major surgery. Therefore, there is an urgent need to find radiosensitizing agents...
Combined immune checkpoint blockade has led to rare autoimmune complications, such as fatal myocarditis. Recent approvals of several anti-programmed death 1 (anti-PD-1) drugs for lung cancer treatment prompted ongoing clinical trials that directly combine PD-1...
In many European countries, patients with a variety of chronical inflammatory diseases are treated with low-dose radiotherapy (LD-RT). In contrast to high-dose irradiation given to tumor patients, little is known about radiobiological mechanisms underlying this...
Cancer treatment has come a long way in a short time, however as new drugs and treatments are developed, the therapeutic index of treatments needs to be assessed. In their study “Inhibition of ataxia telangiectasia related-3 (ATR) improves therapeutic index in...
Radiotherapy enhances innate and adaptive antitumor immunity; however, the effects of radiation on suppressive immune cells, such as regulatory T cells (Treg), in the tumor microenvironment (TME) are not fully elucidated. Although previous reports suggest an increased...
