Characteristic of mucosal immunity is the production of secretory IgA (SIgA) by local plasma cells at the mucosal tissues and secretory glands. The IgA secretion into luminal side is a complex process, involving various steps of molecular and cellular interactions among the immunocompetent cells. These comprise (1) initiation of mucosal responses in the gut lymphoid tissues (gut-associated lymp…

The presence of immunocompetent of bronchial asthma in hypersitive individuals. The cells comprise various populations, such as mat cells, basophils, neutrophils, macrophages, dentritic cells and lymphocytes, in which the T--cells are believed to play a centralrole. It has been demonstrated than CD4 T-cells consist of CD45RO reactive population and CD45RA, each secreting different cytokines. In…
