This book was released on 2007 with total page 11 pages. Available in PDF, EPUB and Kindle. Book excerpt: The goal of this project is to characterize T cell tolerance to prostate tumor antigens and to identify the role of costimulatory receptors in overcoming this tolerance. Identification of these processes will assist in the development of novel therapeutic approaches for treating prostate cancer. We use the TRAMP model a transgenic mouse line that develops primary prostatic tumors due to expression of the SV40 T antigen (TAg) under the transcriptional control of a prostate-specific promoter. In this final addendum summary we report that subsequent to adoptive transfer of naive TAg-specific T cells into TRAMP mice there is rapid expansion and contraction of the tumor-specific T cells followed by accumulation of a population of T cells that persist in the prostate as tolerant and suppressive. Co-transfer of TAg-specific CD4+ T cells delays the tolerant suppressive phenotype of prostate-tumor-specific T cells. Transfer of CD4+ T cells does not reverse tolerance of previously-tolerized CD8+ cells. The suppressive nature of these CD8+ T cells was also studied and we demonstrate that suppression is at least in-part mediated by secreted factors. Further we demonstrate that trafficking od T cells to the TRAMP prostate may be mediated by chemokines. These data demonstrate the critical balance between T cell activation and tolerance and support a mechanism by which tumor growth may induce tolerance and suppressor activity in T cells previously primed to tumor-specific antigens. A greater understanding of how tolerance of these tumor specific T cells can be reversed will certainly lead to more potent anti-tumor immunotherapies.

Book excerpt: The goal of this project is to characterize T cell tolerance to prostate tumor antigens and identify the role of costimulatory receptors in overcoming this tolerance. Identification of these processes will assist in the development of novel therapeutic approaches for treating prostate cancer. We use the TRAMP model, a transgenic mouse line that develops primary prostatic tumors due to expression of the SV4O T antigen (TAg) under the transcriptional control of a prostate-specific promoter. In this summary, we report that adoptive transfer of naive TAg-specific T cells into TRAMP mice results in an initial proliferative expansion followed by a clonal deletion within 5 days. Vaccination of mice with dendritic cells pulsed with the cognate antigen results in expansion in the peripheral lymphoid compartments and subsequent trafficking to the Prostate-draining lymph nodes (pDLN). However, 11 days post-vaccine, Ag-specific T cells were no longer detectable in pDLN. In contrast, a large percentage of Ag-specific T cells were still present in the prostatic tissue of vaccinated TRAMP mice, and persisted for at least 21 days. These data demonstrate that an Ag-pulsed DC vaccine may "rescue" prostate-specific T cells from peripheral tolerance in tumor-bearing mice and promote their infiltration and survival in the prostate. On going studies are testing the role of CTLA-4 blockade and CD4+ T cell help to rescue this deletion.

Download or read book Mycoses in AIDS Patients written by Geert Cauwenbergh and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 329 pages. Available in PDF, EPUB and Kindle. Book excerpt: The World Health Organization estimates that at least five million people worldwide are infected with human immunodeficiency virus (HIV) Of these about 100,000 are in Asia and Oceania, 500,000 in Europe, 2 million in the Americas and 2.5 million in Africa (Mann, 1989). The acquired immunodeficiency syndrome is characterized by a derangement in cell-mediated immunity leading to opportunistic infections with for example Mycobacterium spp., Candida spp., Cryptococcus neoformans, Pneumocystis carinii, Toxoplasma gondii and Cryptosporidium. The third symposium on "Topics in Mycology" brought together 265 experts from 32 countries to discuss the epidemiology, immmunological and pathogenetic aspects of AIDS and its opportunistic infections in general and fungal infections in particular. Pneumocystis carinii pneumonia is by far the commonest opportunistic infection in AIDS patients. The nature and classification of P. carinii is still controversial. In search for its true taxonomic affinities an introductory paper formulates a number of key questions. Candidosis is another frequent opportunistic infection. A number of papers discuss the possibility that selective pressures may operate on Candida albicans within the AIDS population and influence its nature: this might have an impact on prophylaxis and curative and/or suppressive therapy.

Download or read book Carbonic Anhydrase Mechanism Regulation Links to Disease and Industrial Applications written by Susan C. Frost and published by Springer Science & Business Media. This book was released on 2013-10-22 with total page 429 pages. Available in PDF, EPUB and Kindle. Book excerpt: The study of carbonic anhydrase has spanned multiple generations of scientists. Carbonic anhydrase was first discovered in 1932 by Meldrum and Roughton. Inhibition by sulfanilamide was shown in 1940 by Mann and Keilin. Even Hans Krebs contributed to early studies with a paper in 1948 showing the relationship of 25 different sulfonamides to CA inhibition. It was he who pointed out the importance of both the charged and uncharged character of these compounds for physiological experiments. The field of study that focuses on carbonic anhydrase (CA) has exploded in recent years with the identification of new families and isoforms. The CAs are metalloenzymes which are comprised of 5 structurally different families: the alpha, beta, gamma, and delta, and epsilon classes. The alpha class is found primarily in animals with several isoforms associated with human disease. The beta CAs are expressed primarily in plants and are the most divergent. The gamma CAs are the most ancient. These are structurally related to the beta CAs, but have a mechanism more similar to the alpha CAs. The delta CAs are found in marine algae and diflagellates. The epsilon class is found in prokaryotes in which it is part of the carboxysome shell perhaps supplying RuBisCO with CO2 for carbon fixation. With the excitement surrounding the discovery of disease-related CAs, scientists have redoubled their efforts to better understand structure-function relationships, to design high affinity, isotype-specific inhibitors, and to delineate signaling systems that play regulatory roles over expression and activity. We have designed the book to cover basic information of mechanism, structure, and function of the CA families. The authors included in this book bring to light the newest data with regard to the role of CA in physiology and pathology, across phylums, and in unique environmental niches.

This book was released on 2012-12-06 with total page 479 pages. Available in PDF, EPUB and Kindle. Book excerpt: Hyperthermia has been found to be of great benefit in combination with radiation therapy or chemotherapy in the management of patients with difficult and com plicated tumor problems. It has been demonstrated to increase the efficacy, of ionising radiation when used locally but also has been of help in combination with systemic chemotherapy where hyperthermia is carried out to the total body. Problems remain with regard to maximizing the effects of hyperthermia as in fluenced by blood flow, heat loss, etc. The present volume defines the current knowledge relative to hyperthermia with radiation therapy and/or chemotherapy, giving a comprehensive overview of its use in cancer management. Philadelphia/Hamburg, June 1995 L.W. BRADY H.-P. HEILMANN Preface In an attempt to overcome tumor resistance, hypoxia, or unfavorable tumor condi tions, oncological research has come to focus on gene therapy, immunotherapy, new cytotoxic agents, and increasingly sophisticated radiotherapy. Radiation research has been directed towards heavy particle therapy and modification of the radiation response by either protecting or sensitizing agents. Improved dose localization using rotational or conformal strategies has also been implemented. Recently, changes in radiation fractionation schedules have shown promise of better results. Hyperthermia in cancer therapy can be viewed similarly as another means to increase the sensitivity of tumors to radio- and chemotherapy.

Download or read book Immunomodulatory Agents from Plants written by Wagner and published by Birkhäuser. This book was released on 2012-12-06 with total page 390 pages. Available in PDF, EPUB and Kindle. Book excerpt: The human immune system, despite having its own sophisticated defence mecha nisms, is inferior to bacteria and viruses with respect to adaptability. Furthermore, our immune system is increasingly exposed to detrimental effects, that is immuno suppressive environmental consequences, unhealthy living, and chronic illnesses. Excessive chemotherapy threatens our immune system even further. This situation demands compensatory prophylactic therapeutic regimes. One of these - specific immunostimulation - is more difficult to achieve than the immunosuppression cur rently used in transplantation surgery and the medical treatment of autoimmune dis eases. The earliest attempts to develop suitable medication for immunostimulation were based on traditional remedies which embodied the accumulated experience of several centuries. Medicinal plants are already being used prophylactically as stan dardized and efficacy-optimized preparations for the treatment of various recur rent infections, or in combination with chemotherapeutics in standard medical practice. In order to rationally apply immunostimulants of plant origin, however, it is necessary to search for the active principles of these substances and to produce them in a pure form. Because suitable screening methods have become available only recently, research in this field is in its very beginning. Further progress can be expected from systematic basic research on the mechanisms underlying immunomodulation. This also applies to verification of clinical efficacy, which is a prerequisite for the acceptance of medications with purported immunostimulatory properties.
