abstract background and objective: scientific evidence reveals that the density of skeletal muscle microcirculations decreases in the patients with chronic heart failure. therefore, this study aimed to determine the impact of submaximal aerobic exercise training on restoration of fast/slow-twitch muscle fibers microcirculation in rats with myocardial infarction. methods: in thi...
Angiogenesis or formation of new blood vessels from preexisting vasculature is a key process in some physiological conditions such as wound healing, growth, and action of female reproductive organs. Moreover, disturbance of the mechanisms of physiological angiogenesis has a role in pathogenesis of some diseases in the form of overproliferation of blood vessels such as cancers, psoriasis, arthri...
Background Immunotherapies that target immune-checkpoint molecules such PD-1 have helped to achieve durable responses in melanoma treatment. However, 25% of melanoma patients who showed objective responses to PD-1 blockade develop resistance and suffer from disease progression and ultimately death, which necessitates the identification of related resistance mechanisms.IL-34 is a cytokine that c...
The role of a tumor immune infiltrate in cancer progression and metastasis has been debated frequently. Although often considered to be associated with improved prognosis and leading to the enhanced survival of cancer patients, inflammatory cells have also been described to assist the tumor's capabilities to progress, proliferate, and metastasize. Tumor-associated macrophages (TAMs), for exampl...
Tumor endothelial marker 1 (TEM1; also known as endosialin or CD248) is a protein found on tumor vasculature and in tumor stroma. Here, we tested whether TEM1 has potential as a therapeutic target for cancer immunotherapy by immunizing immunocompetent mice with Tem1 cDNA fused to the minimal domain of the C fragment of tetanus toxoid (referred to herein as Tem1-TT vaccine). Tem1-TT vaccination ...
Mast cells are abundant at the periphery of the majority of solid tumors where they typically promote angiogenesis and enhance tumor growth. However, there is some evidence from epidemiological studies that allergic disease reduces cancer risk. In the context of infection, mast cell activation with Toll-like receptor (TLR) agonists induces the production of multiple mediators which mobilize and...
Communication between leukemia cells and their environment is essential for the development and progression of leukemia. Exosomes are microvesicles secreted by many types of cells that contain protein and RNA and mediate intercellular communication. The involvement of exosomes has been demonstrated in the crosstalk between leukemic cells, stromal cells and endothelial cells, consequently promot...
background: the use of dendritic cells (dcs) as a cellular adjuvant provides a promis-ing approach in immunotherapy of cancer. it has been demonstrated that listeria mono-cytogenes activated dcs pulsed ex vivo with tumor antigens trigger a systemic th1-biased specific immune response and a single dose of this vaccine will cause a consider-able anti tumor immunity. objective: the present study w...
Cancer is a major public health problem and the second leading cause of mortality around the world. Antitumor immunotherapy using monoclonal antibodies is considered selective and efficient in the treatment of different types of tumors, but its cost and toxic effects limit its application. Many tumor microenvironments, including lymphoma and carcinoma, are enriched in immune suppressive cells t...
The therapeutic approach for the second-line treatment of patients with advanced non-small cell lung cancer (NSCLC) without actionable mutations has been revolutionized by the recent approval of new effective drugs with various mechanisms of action, including nintedanib, ramucirumab, nivolumab, pembrolizumab, atezolizumab, and afatinib. The recent network meta-analysis of Créquit et al. (BMC Me...
