Recirculation and Homing of Lymphocyte Subsets: Dual Homing Specificity
The p7-integrin subunit can pair with two a-chains, a4 and aE, and is expressed mainly on lymphocytes. As an a4-heterodimer it binds to the mucosal addressin MAdCAM-1, thus acting as a mucosal homing receptor. As an aE-heterodimer it binds to E-cadherin and is mainly found on intestinal intraepithelial lymphocytes. Consequently, p7 is mostly expressed on lymphocytes of the mucosal immune system...
متن کاملTraffic signals on endothelium for lymphocyte recirculation and leukocyte emigration.
The circulatory and migratory properties of white blood cells have evolved to allow efficient surveillance of tissues for infectious pathogens and rapid accu mulation at sites of injury and infection. Lymphocytes continually patrol the body for foreign antigen by recirculating from blood, through tissue, into lymph, and back to blood. Lymphocytes acquire a predilection, based on the environmen...
متن کاملLymphopoiesis and lymphocyte recirculation in the sheep fetus
The production and the circulation of lymphocytes has been examined in the sheep fetus where neither foreign antigen nor immunoglobulins occur. It was found that as the lymphoid organs increased in size during fetal life, the numbers and the output of lymphocytes in the thoracic duct lymph increased. The recirculating pool of lymphocytes was estimated to be 5.5 +/- 1.5 X 10(8) cells in fetal la...
متن کاملPractice review of five bioreactor/recirculation landfills.
Five landfills were analyzed to provide a perspective of current practice and technical issues that differentiate bioreactor and recirculation landfills in North America from conventional landfills. The bioreactor and recirculation landfills were found to function in much the same manner as conventional landfills, with designs similar to established standards for waste containment facilities. L...
متن کاملType I interferons directly regulate lymphocyte recirculation and cause transient blood lymphopenia.
Early viral infection is often associated with lymphopenia, a transient reduction of blood lymphocyte counts long before the onset of clinical symptoms. We have investigated lymphopenia in mice infected with vesicular stomatitis virus (VSV) or treated with the Toll-like receptor (TLR) agonists poly(I:C) and R-848. In all cases analyzed, lymphopenia was critically dependent on type I interferon ...
