MABS
MABS are made by fusing spleen cells and melanoma cells to make hybridoma cells.
these cells are then cloned and screened for the desired antibody. the chosen hybridomas are then grown in a lab in large batches to make MABS
-
monoclonal antibodies
uses
-
cancer
Mabs are able to treat some types of cancer. they trigger an immune response causing the cell membrane to be destroyed and stop cell growth
MABS are used to treat a very wide range of antigens and are used to target a large range of diseases
-
secondary
immune response
the secondary exposure is when a person if infected with a disease for the second time. this is faster than the first as the body has memory cells
-
memory cells are the bodys way of making sure that the person is not heavily affected by a pathogen again. these memory cells remember the chemical signature of a pathogen and the antibodies needed to combat it.
-
specific defences
the specific defence is the lymphocyte, these produce antibodies specific to the pathogens antigens that clump pathogens together for phagocytes to engulf the pathogens. these lymphocytes then become memory cells
