Defensins and Innate Immunity of the Mammalian Small Intestine
The release of gene-encoded antimicrobial peptides by epithelial cells is thought to contribute to innate mucosal immunity. Defensins are a predominant class of such antimicrobial peptides in mammals. These cysteine-rich cationic peptides have antibiotic activity against a wide range of bacteria and other microbes. In the mammalian small intestine, Paneth cells at the base of the crypts of Lieb...
متن کاملInnate immunity and adjuvants
Innate immunity was for a long time considered to be non-specific because the major function of this system is to digest pathogens and present antigens to the cells involved in acquired immunity. However, recent studies have shown that innate immunity is not non-specific, but is instead sufficiently specific to discriminate self from pathogens through evolutionarily conserved receptors, designa...
متن کاملInnate Immunity and Neuroinflammation
Inflammation of central nervous system (CNS) is usually associated with trauma and infection. Neuroinflammation occurs in close relation to trauma, infection, and neurodegenerative diseases. Low-level neuroinflammation is considered to have beneficial effects whereas chronic neuroinflammation can be harmful. Innate immune system consisting of pattern-recognition receptors, macrophages, and comp...
متن کاملInnate and acquired immunity
• The cells of the immune system are divided into lymphoid and myeloid lineages. The former include T lymphocytes and their subsets identified by CD markers, B lymphocytes and natural killer (NK) cells. The myeloid lineage includes the neutrophils, eosinophils and basophils as well as the monocyte/ macrophage series and platelets. • Innate immunity depends on physical, physiological and chemica...
متن کاملInnate immunity
From the discovery of antibodies in the late nineteenth century until very recently, the focus of most research in immunology has been the so-called adaptive immune response. Adaptive immune responses are highly specific for a given microorganism and it is the T and B lymphocytes of the adaptive immune response, and the antibodies produced by the B lymphocytes, that are responsible for lasting ...
