T-cell Activation in Health and Disease is a collection of papers presented at the "T-cell Activation in Health and Disease—Disorders of Immune Regulation—Infection and Autoimmunity" workshop held in Oxford on September 25-29, 1988. This book discusses the progress occurring in T-cell immunity research. One paper discusses the effects of two interaction clones of T-cells that can define the T-cell immunoregulatory network. Another paper discusses the relationship between connectivity and tolerance of the immune network. This paper then suggests the possibility that autoimmunity arises because self-reactive clones are inadequately connected to the network. Another paper reviews the cell-mediated responses in the synovial fluids, as well as the interaction of rheumatoid arthritis synovial fluid dendritic cells and T lymphocytes. The book also examines why attempts for protective immunity to the HIV virus have not been successful. One article then discusses the goals of immunologic intervention in autoimmune disease by using an approach involving the cellular and cytokine targets and their deployment. This text can prove significant for scientists in the field of pharmacology, cellular biology, and researchers in the field of immunology and infectious diseases.
