Cytokines in radiobiological responses: a review.

Cytokines function in many roles that are highly relevant to radiation research. This review focuses on how cytokines are structurally organized, how they are induced by radiation, and how they orchestrate mesenchymal, epithelial and immune cell interactions in irradiated tissues. Pro-inflammatory cytokines are the major components of immediate early gene programs and as such can be rapidly activated after tissue irradiation.

Radiation enhances regulatory T cell representation.

Purpose: Immunotherapy could be a useful adjunct to standard cytotoxic therapies such as radiation in patients with micrometastatic disease, although successful integration of immunotherapy into treatment protocols will require further understanding of how standard therapies affect the generation of antitumor immune responses. This study was undertaken to evaluate the impact of radiation therapy (RT) on immunosuppressive T regulatory (Treg) cells.

Methods And Materials: Treg cells were identified as a CD4(+)CD25(hi)Foxp3(+) lymphocyte subset, and their fate was followed in a murine TRAMP C1 model of prostate cancer in mice with and without RT.

Minimally invasive total gastrectomy for gastric cancer: a pilot series.

Background: Minimally invasive surgery for select gastrointestinal disease has gained worldwide acceptance. However, laparoscopic total gastrectomy for cancer remains controversial. The purpose of this study was to examine an initial experience with laparoscopic total gastrectomy.

Cytoprotective gene HO-1 and chronic rejection in heart transplantation.

Chronic rejection in transplanted hearts or cardiac allograft vasculopathy (CAV) is the leading cause of late death among heart transplant recipients. We hypothesized that induction of HO-1 by D4-F, an apoA-I mimetic peptide with potent antiinflammatory/antioxidant properties, attenuated CAV. We utilized a previously characterized murine model of CAV.
