Unit 4 8B: Treatment of disease Flashcards
Immunotherapy
A treatment that uses activation or suppression of the immune system
Monoclonal Antibody
(mAb)
Antibody made by cloning of unique parent immune cells, produced in large quantities in the laboratory as a drug targeting specific cells or substances
Bispecific monoclonal antibody
A monoclonal antibody that has two different antigen binding sites
Conjugated monoclonal antibody
An antibody that has been combined with a radioactive substance or chemotherapy agent (a cytotoxin)
Myeloma Cell
An abnormal plasma cell used in the production of monoclonal antibodies
Hybridoma
A cell that is a result of combining a B lymphocyte and a cancer cell
Zoonosis
A disease which can be transferred from animals to humans
Steps of immunotherapy
- Cancer cell antigen is injected into mouse
- Mouse undergoes an adaptive immune response
- Plasma B cells are extracted and fused with a myeloma /tumor cell to form a hybridoma
- Hybridoma divides rapidly (characteristic of tumour cell) and produces lots of specific antibodies
- Specific antibodies are extracted and purified
Side effects of mAbs
Allergic reaction, fever, rash
Are conjugated mAbs and Bispecific mAbs activating or suppressing the immune system
Activating (stimulating by assisting immune response, and action of Tc cell)
How can mAbs suppress immune system
mAbs which target autoimmune disease, which suppress the immune system
