Mucosal Immune System
Mucosal immunology is the study of immune system responses that occur at Mucous membrane, mucosal membranes of the Gastrointestinal tract, intestines, the Genitourinary system, urogenital tract, and the respiratory system. The mucous membranes are in constant contact with microorganisms, food, and inhaled antigens. In Health, healthy states, the mucosal immune system protects the organism against infectious pathogens and maintains a Immune tolerance, tolerance towards non-harmful Commensalism, commensal microbes and benign environmental substances. Disruption of this balance between Immune tolerance, tolerance and deprivation of pathogens can lead to pathological conditions such as Food allergy, food allergies, irritable bowel syndrome, susceptibility to infections, and more. The mucosal immune system consists of a cellular component, humoral immunity, and defense mechanisms that prevent the invasion of microorganisms and harmful foreign substances into the body. These defense mec ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mucosal Immunity March 18
A mucous membrane or mucosa is a membrane that lines various cavities in the body of an organism and covers the surface of internal organs. It consists of one or more layers of epithelial cells overlying a layer of loose connective tissue. It is mostly of endodermal origin and is continuous with the skin at body openings such as the eyes, eyelids, ears, inside the nose, inside the mouth, lips, the genital areas, the urethral opening and the anus. Some mucous membranes secrete mucus, a thick protective fluid. The function of the membrane is to stop pathogens and dirt from entering the body and to prevent bodily tissues from becoming dehydrated. Structure The mucosa is composed of one or more layers of epithelial cells that secrete mucus, and an underlying lamina propria of loose connective tissue. The type of cells and type of mucus secreted vary from organ to organ and each can differ along a given tract. Mucous membranes line the digestive, respiratory and reproductive tract ...
