Natural resistance is now coming to be recognized as a potentially important phenomenon in host defense against infection and ma lignancy. Genetically controlled resistance mechanisms are usUally effective early in infection and before conventional immune responses are generated. Comparisons of experimental systems where natural resistance plays a prominent role demon strate the complexities of the host defense mechanisms involved, as evidenced in the present volume. Nevertheless, some com mon components of genetic resistance are discernible and largely comprise natural killer cells, macrophages, and interferon These and additional factors would seem to constitute a first line of de fense in host resistance against both viruses and tumors. It is evi dent that considerable variation in the relative importance of di stinct mechanisms may be found among various resistance sy stems and that, most likely, additional effector functions will be discovered. Resistance to tumors and most viruses is under polygenic control, has a complex mode of inheritance, and depends on appro priately complex effector mechanisms. Instances, however, whe re a single gene locus determines resistance or susceptibility to a virus, as in the case of resistance to flaviviruses or influenza viru ses, would seem to offer good prospects for elucidating the basic factors involved. Resistance to influenza virus would indeed seem to represent a comparatively simple situation: resistance is expressed at the host cell level, and interferon is its main media tor. The present volume provides insight into current concepts of such resistance mechanisms.

Genetic Control of Natural Resistance to Infection and Malignancy ...

The ability to genetically engineer oncolytic viruses in order to minimize side effects and improve the selective targeting of tumor cells has opened up novel opportunities for treating cancer. Understanding the mechanisms involved and the complex interaction between the viruses and the immune system will undoubtedly help guide the development of new strategies. Theranostic biomarkers to monitor these therapies in clinical trials serve an important need in this innovative field and demand further research.

This volume examines in detail the role of chronic inflammatory processes in the development of several types of cancer. Leading experts describe the latest results of molecular and cellular research on infection, cancer-related inflammation and tumorigenesis. Further, the clinical significance of these findings in preventing cancer progression and approaches to treating the diseases are discussed. Individual chapters cover cancer of the lung, colon, breast, brain, head and neck, pancreas, prostate, bladder, kidney, liver, cervix and skin as well as gastric cancer, sarcoma, lymphoma, leukemia and multiple myeloma.
