Cellular Immunity in Vitro
An in vitro model of cellular immunity in the guinea pig was established. Animals were immunized with tubercle bacilli, bovine gamma globulin, or picrylated human serum albumin in complete Freund's adjuvant. Oil-induced peritoneal exudates from immune and control animals were cultured overnight with and without specific antigen. The cultures were washed and the macrophage monolayers were infect...
متن کاملCellular Immunity in Vitro
When sensitive lymphocytes are cultured with the appropriate antigen, lymphoblasts appear after 24-48 hr of incubation and the number of these increases steadily from the 2nd to the 6th or 7th day. Our problem was to discover, at a cellular level, how this increase takes place; whether it is a massive response of many cells, stepwise recruitment of cells into the lymphoblast class, or simply re...
متن کاملGlucocorticoids and Cellular Immunity in Vitro
We studied the influence of glucocorticoids on the sensitization phase as well as on the cytolytic effector phase of an in vitro lymphocyte-mediated immune reaction. Lymphocytes obtained from the spleens or lymph nodes of unimmunized inbred rats were sensitized against foreign rat or mouse embryonic fibroblasts in cell culture. The capacity of the sensitized lymphocytes to produce a cytolytic e...
متن کاملCellular immunity in pertussis.
Considerable advances have been made recently in our understanding of the pathogenesis and the immunological mechanisms involved in the prevention and control of infection by Bordetella pertussis. Traditionally , research on protection has focused on the role of humoral immunity and several reports have shown that passive transfer of antibodies against several putative protective antigens, incl...
متن کاملTetraspanins in cellular immunity.
Tetraspanins are a superfamily of integral membrane proteins involved in the organization of microdomains that consist of both cell membrane proteins and cytoplasmic signalling molecules. These microdomains are important in regulating molecular recognition at the cell surface and subsequent signal transduction processes central to the generation of an efficient immune response. Tetraspanins, bo...
