The understanding of the immune mechanisms underlying autoimmunity and immune diseases has significantly deepened and broadened. The current book helps to know the key symptoms, diagnostic procedures and conventional treatment for the most common autoimmune diseases so that the reader could better understand what it means to have an autoimmune disease, and the impact the autoimmune process has on current and future health. This book incorporates clinico-pathologic correlations and combines common themes underlying inductive and effector mechanisms and therapies that relate generally to the autoimmune disorders. Additionally, the book discusses the biological basis of disease at genetic, molecular, cellular and epidemiological levels and includes expanded coverage of these diseases. The current book therefore, provides through, up to date information on specific diseases, along with clinical implications, in an easily found reference for clinicians and researchers interested in certain diseases and keeps scholars/readers abreast of current trends and emerging areas in the field.
