Biological modifying drugs and DMARDS Flashcards
(69 cards)
What do modifying drugs/biological response do?
Alter the body’s response to diseases such as cancer, autoimmune, inflammatory and infectious diseases
Categories of modifying drugs
Hematopoietic drugs and immunomodulating drugs
Types of Immunomodulating drugs
Interferons(IFNs)
Monoclonal antibodies (MABs)
Interleukin (IL) receptor agonists and antagonists
others
Immunomodulating drugs
therapeutically alter a patients immune response to malignant tumour cells by modifying the bodies own immune response so that it can destroy various viruses and cancerous cells
What are the fourth parts of cancer therapy
Surgery, chemotherapy, radiation and immunomodulating drugs
What diseases are immunomodulating drugs for
Autoimmune diseases, inflammatory diseases and infectious diseases
Subclasses of modifying drugs
Hematopoietic drugs, IFNs, MARBs, interleukin receptor agonists/antagonists, disease modifying antirheumatic and others
MOA of modifying drugs
Enhancement of hematopoietic(function of bone marrow) function
Enhancement of regulation of the host’s immune system defences against the tumor
Inhibition of metastases prevention of cell division or inhibition of cell maturation
What does the immune system do
Recognize and destroy foregin particles and cells in the blood or other blood or any other tissue
Humoral immunity mediated by?
Mediated by the b-cell functions (antibodies)
Cell mediated immunity mediated by?
Mediated by T-cell functions
What do tumour antigens do to tumor cells
They mark the tumor cells as abnormal cells so the antibodies can attack them
How do the antibodies attack the tumor cells?
the B(B cells) lymphocytes from the humoral immune system and the T (T cells) lymphocytes from the cell mediated immune system
Where do B lymphocytes originate
the bone marrow
What do B cells do?
- The b cells turn into plasma cells which then produce antibodies that will kill the antigen (antibody-antigen complex)
- Develops into when encounter a new antigen memory cells
Monoclonal antibodies (MABs)
Are immunoglobulins derived from a dingle cell
Five major types of naturally occuring immunoglobulins (types of antibodies)
A,D,E,G and M
Where do T lymphocytes originate
Also originate from bone marrow but mature in the thymus gland
Three types of T Cells
Cytotoxic T Cells
T-Helper cells
T-suppressor cells
What does a cytotoxic T cells do?
Kill their targets by causing cell lysis or rupture
What does T helpers do?
Direct the actions of many other components of the immune system to the antigens
What do T suppressors do?
Limit or control the immune response
What does an overactive T suppressor cells mean for cancer cases
may be the cause of cancer cases as it permits tumour growth beyond immune system control
Therapeutic effects of biological response-modifying frugs
Enhance hematopoietic function, enhance/regulate the immune response including cytotoxic or cytostatic activity against cancer cells, inhibits metastases, division and cell maturation
