Macrophages Cancer

Maurie Markman and a panel of distinguished clinicians and leading clinical investigators comprehensively review the current status of regional antineoplastic drug delivery in the management of malignant disease. These authorities present a critical analysis of both the rationale and limitations of regional therapy and discuss potential clinical trials designed to explain the effectiveness of this method of therapy in special settings. Their presentations describe many exciting and innovative strategies for using regional drug delivery in anticancer therapy, including coverage of such areas of special interest as colorectal, skin, lung, pancreatic, ovarian, and gastrointestinal cancers. Comprehensive and authoritative, Regional Chemotherapy: Clinical Research and Practice offers surgical and medical oncologists and clinical cancer investigators a gold-standard review of the current role and future development of this increasingly powerful weapon in the battle against cancer.

Tumor development and progression are strongly linked to inflammation and macrophage infiltration is a major component of the inflammatory reactions associated with neoplasia. Plasticity is a hallmark of mononuclear phagocytes, which undergo polarized diverse forms of activation. Metabolic adaptation is a key component of macrophage plasticity and polarization, instrumental to their function in homeostasis, immunity and inflammation. Tumor-associated macrophages (TAM) and related immature myeloid suppressor cells generally have properties of an M2-like population. TAM produce growth factors, have immunoregulatory and immunosuppressive activity, stimulate angiogenesis and provide tissue remodeling, invasion and metastasis. Thus, TAM are a key component of cancer-promoting inflammatory reactions.

The subject of Tumour-Associated Macrophages is of interest in the cancer research community, and this book promises to be among the first to discuss a definitive theory on the role of macrophage in tumor development.

First Published in 1988, this book offers a full, comprehensive guide into the relationship between macrophages and Cancer. Carefully compiled and filled with a vast repertoire of notes and references this book serves as a useful reference for Students of Medicine, Oncology and other practitioners in their respective fields.

This book is a collection of chapters that discuss methodologies, resources, and technologies by dedicated authors. This book has addressed the significance of macrophages in infectious disease, tumor metabolism, and muscular disorders. All chapters have focused on the fate of differentiated macrophages and discussed molecular pathways that are important for the pathologic role of macrophages. I am confident that our readers will find this book useful in designing immune mediated strategies for managing various diseases that this book is based on.

Since the introduction of microscopy, pathologists have noted tumor infiltration by inflammatory cells and presumed that this represents the host's attempt to reject its tumor. Recent advances in the molecular biology of inflammation have revealed the signals involved in attracting inflammatory cells to tumors and, for the most part, these signals are mediated by chemokines and their receptors. Chemokines are low molecular weight proteins that attract and activate specific subsets of leukocytes to the exclusion of others.

Fresh living Bacillus Calmette-Guerin (BeG), injected i.v. into (C57BI/ 6xDBA/2)FI mice, activated peritoneal macrophages rendering them highly cytotoxic for tumor cells in vitro. This cytotoxic activity w~s already maximal 14 days after injection of 1 mg of BCG and remained stable when 3 or 5 mg of BCG were given. At the same time spleen cells of the BCG-treat~d mice showed strongly depressed responses to the T-cell mitogens,PHA and Con A, irrespective of the dose of BCG injected. The inhibitory effect was shown to be mediated by suppressor cells which had characteristics of macrophages since they could be removed by carbonyl iron and magnet treatment and were adherent to plastic. In contrast to it was observed after injec tion of 1 mg of BCG, these suppressor cells alone did not account for the depression of T-cell re.sponses induced by higher doses of BCG. Nylon-nonadherent cell populations obtained from spleen cells treated with 3 or 5 mg BCG partially retained the inhibitory activity suggesting that suppressor T cells were also induced after injection of high doses of BCG. In contrast, the responses to the B-cell mitogen LPS of unfractionated and macrophage-depleted spleen cells were not affected or significantly enhanced depending on the dose of BCG injected.

The Macrophage in Neoplasia is a compilation of papers presented at a workshop held at the Marine Biological Laboratory, Woods Hole, Massachusetts, on October 8-11, 1975. The book presents the many faceted activities of macrophage. This book is divided according to the five sessions of the workshop. First session talks about the role of tumor macrophages in vivo. It then elucidates the macrophage function and indicates how the interaction of macrophages with other cells can alter the host-tumor balance. The remaining sessions, as presented in this book, explore the mechanism of macrophage mediated cytotoxicity, functional expression of macrophages and neoplasia, and the stimulation of macrophage function and applied therapy.
