The immune system is a complex network in which different cell types and soluble factors interact to efficiently eliminate various kinds of microorganisms as well as aberrant cell clones. Since the earliest report of a successful immunotherapy in the late 1700s, much knowledge has been accumulated, and today investigations of the molecular mechanisms of immune regulations are of central research interest. The novel insights into gene polymorphisms and gene regulation gathered from this work have improved our knowledge of individual immune reactions and risk factors in overcoming infections, yet the hope for greater therapeutic success in the clinical setting is still limited. In the field of immunoregulation, enormous effort is still required to increase fundamental understanding and the therapeutic benefit, a goal that can only be achieved with further research and basic science. Cytokines and Colony Stimulating Factors: Methods and Protocols promotes the recent knowledge and understanding generated by novel technologies in order to spread awareness of its useful applications. This book will address both the needs of novice investigators by providing detailed descriptions of methods and trouble-shooting notes, and also qualified scientists working on the therapeutic benefits for future patients suffering from these diseases.
