The interactions between neurons, immune and immune-like glial cells can initiate the abnormal processes that underlie neuropathic pain. In the peripheral nervous system the resident macrophages may play an important role. In this study we investigated in experimental adult Sprague-Dawley rats how Iba-1 (ionized calcium binding adaptor molecule 1) (+)(More)
Adipose tissue displays characteristics of an endocrine organ releasing a number of adipocyte-specific factors known as adipocytokines. It has been recently suggested that adipocytokines may play a role in pathogenesis and progression of certain cancers, in particular in colorectal cancer. The aim of this study was to investigate the association between(More)
Immunity plays an important role in the prognosis and the natural development of cancer. Previous studies have shown that the presence of tumor in the body could modify the immune response leading to immunosuppression. The aim of this study was to evaluate the immunological changes of patients with larynx squamous cell carcinoma undergoing potentially(More)
AIMS AND BACKGROUND Macrophages are heterogeneous cells with extensive functional plasticity; they can change their functional profiles repeatedly in response to environmental changes anywhere between their extreme phenotypical programs (labeled as M1 and M2 polarization, respectively). In terms of antitumoral immune response, M1 macrophages are considered(More)
OBJECTIVE Altered immune, inflammatory, and angiogenesis responses have been noticed in head and neck cancer, and many of these responses have been associated with a poor clinical outcome. The objective of this study was to evaluate several immune mediators in the sera of patients with squamous cell carcinoma (SCC) of the larynx undergoing curative surgery(More)
Acute Bacterial Meningitis is a medical emergency, which warrants early diagnosis and aggressive therapy, which in most cases must be initiated as an "empirical" treatment. Such an approach needs permanent epidemiological surveillance due to the major variability of the etiological agents depending upon time, geographical areas and demographic(More)
The aim of the study was to investigate the perioperative immunological profile in colon cancer patients and possible correlations with disease. To investigate the changes in immune mediators profile induced by tumor resection, we assessed the serum levels of cytokines (IL-6, IL-8, IL-10, IFN-gamma, TNF-alpha), chemokines (MIP-1alpha, MCP-1, ENA-78) and(More)
Neonates are highly sensitive to infections because they are biased to develop Th2 immune responses. When exposed to certain agents, such as DNA vaccines or CpG DNA motifs, neonates are capable to mount adult-like Th1 protective responses. This study investigates the capacity of Candida albicans (C. albicans) dsDNA to induce host resistance in newborn mice(More)
Cell culture is one of the major tools for oncology research, being an excellent system in which to study the biochemistry and molecular biology associated with individual cancer types and to understand cancer cell physiology. Progress in understanding the biology of any type of carcinoma has been impeded by the inability to culture adequately malignant(More)
The hepatitis C virus (HCV) is a major etiologic agent for severe liver diseases (e.g. cirrhosis, fibrosis and hepatocellular carcinoma). Approximately 140 million people have chronic HCV infections and about 500 000 die yearly from HCV-related liver pathologies. To date, there is no licensed vaccine available to prevent HCV infection and production of a(More)
