The Launch Manager software is basically a keyboard driver, but for enhanced keyboard functions -- the play, pause, stop, volume and Windows function keys on laptop computers. The software launches when the computer loads Windows and allows you to customize action keys on your keyboard.
Humoral immunity is called active when the organism generates its own antibodies, and passive when antibodies are transferred between individuals or species. Similarly, cell mediated immunity is active when the organismsâ own T-cells are stimulated, and passive when T cells come from another organism.
The many resulting T cells can then stimulate other T cells to attack the foreign pathogen, or they can stimulate B cells to produce antibodies. These antibodies, along with other cells in the immune system, then destroy the foreign invaders, helping to ensure the health of the individual.he macrophage is just one cell type that may present antigens in the MHCII complex; other cells, including B cells and dendritic cells, may also act as antigen-presenting cells (APC). Only a few helper T cells in the immune system will recognize the specific antigen presented by the APC.
