Synopsis

All multicellular organisms may possess innate immunity mediated by defense mechanisms with which the organism is born. In recent years much has been learned about the diversity of innate immune mechanisms. A large array of naturally produced antimicrobial peptides has been de­ fined. A variety of cell surface receptors that recognize common patterns displayed by infectious organisms have been identified along with the intracellular pathways that these receptors use to activate cellular defense functions. Cell surface receptors on natural killer (NK) cells have been shown to sense microbial invasion in neighboring cells, thereby setting into motion their elimination by cy­ totoxic mechanisms. Other receptors have been found to facilitate phagocytosis and intracellular killing of microbes by phagocytic cells. These and other natural defense mechanisms have traditionally been viewed as the first line of body defense in vertebrate species that also possess the capacity for acquired or adaptive immunity. Sharks and all of the other jawed vertebrates generate large repertoires of T and B lymphocyte clones that display different antigen­ specific receptors in the form ofT cell receptors (TCR) and immunoglobulins (Ig) that allow them to recognize and respond to antigens in collaboration with antigen-present­ ing cells. Memory T and B cells are then generated to allow faster and heightened cellular and humoral immune re­ sponses on secondary antigen encounter. In recent years it has also become obvious that innate immune responses can directly influence adaptive immune responses in ways that will enhance body defense.

About this title

Synopsis

The topics of this volume include regulation of the helper T cell subset involved in inflammatory responses versus the subset of helper T cells involved in promoting B cells responses in humoral immunity, the regulation of T cell activity in inflammatory and autoimmune disease by the tumor necrosis factor superfamily of receptors and their ligands, the wide array of inhibitory and activating receptor that regulate natural killer cell function, phylogeny of Ig gene superfamily members linked to the major histocompatibility gene complex, the IgFc receptor family and a newly discovered family of Fc receptor homologs, the role of complement in linking innate and adaptive immunity, and manipulation of the potential for plants to protect themselves by innate and adaptive responses to viruses.
