BIOL 640 1st Edition Lecture 16 Outline of Last Lecture I. Cellular Immunity Outline of Current Lecture II.Magnetic Cell separationIII. Hematopoietic systemIV. Activation of cellular immune systemCurrent LectureImmunology Lecture 17: Hematopoietic system:Magnetic cell separation:Paramagnetic beads that are Ab conjugated attach onto green cells, as the magnet is induced. The red cells are removed and green cells are retained. Sandwiching can be done for amplification. This is a cheap and efficient way to get subset of cells to work with.Chicken:The accessory organs such as thymus and bursa were removed to study its impact on the immune system. Thymus is where the T cells mature and Bursa are where B cells mature. Mature T cells are needed for graft rejection and delay type hypersensitivity.Hematopoietic system:Blast transformation- activation of lymphocytes.Activation of cellular Immune system:3 cells that present Ag are:These notes represent a detailed interpretation of the professor’s lecture.

These cells have a half life of 2 years. For tetanus , the half life is 10 years and for small pox it is immortal or lives
