Study Notes
Vaccination
- Vaccinated individuals generate antibodies that effectively neutralize viruses or bacteria, significantly reducing infection rates.
- Vaccination also minimizes the likelihood of transmitting pathogens to others.
Antibiotics and Antivirals
- Antibiotics are potent medications that target bacterial infections by killing bacteria or inhibiting their reproduction.
- The body's natural defenses then work to eliminate the remaining pathogens.
Chemotherapy and Drug Therapy
- Chemotherapy utilizes strong drugs or chemicals, often in combinations, to kill or damage cancer cells.
- Anticancer agents are toxic enough to eliminate leukemic cells, but can also affect healthy cells.
- Successful chemotherapy relies on cancer cells being more susceptible to the drugs than normal cells.
Radiation Therapy
- Also known as radiotherapy, this treatment is used for leukemia, lymphoma, myeloma, and myelodysplastic syndromes.
- Radiation therapy damages the DNA of cells, preventing their growth and reproduction.
- While aimed at cancer cells, it can also affect surrounding healthy cells; however, advancements have reduced collateral damage.
Immunotherapy
- Immunotherapy, or biological therapy, harnesses the body's immune system to combat cancer, typically resulting in fewer short-term side effects than chemotherapy.
- Various immunotherapies currently being studied or used for blood cancer include:
- Chimeric Antigen Receptor (CAR) T-cell therapy
- Cytokine treatment
- Donor lymphocyte infusion
- Monoclonal antibody therapy
- Radioimmunotherapy
- Reduced-intensity allogeneic stem cell transplantation
- Therapeutic cancer vaccines
Stem Cells
- Blood stem cells, produced in the bone marrow, can differentiate into any blood cell type and constantly regenerate to replace older cells.
- Insufficient production of blood cells can lead to serious health issues such as infections, anemia, or bleeding.
- Stem Cell Transplantation (SCT), or bone marrow transplant, introduces healthy stem cells to replace damaged ones, and can also utilize umbilical cord blood.
Tissue Nano-transfection (TNT)
- TNT is an electroporation-based technique that enables gene and drug delivery at the nanoscale, facilitating targeted treatments.
Biotechnology in Health
- Red or healthcare biotechnology applies to medical and food science sectors, enhancing molecular diagnostics, vaccine development, and drug production.
- Key applications include:
- Gene therapy for modifying genetic material to treat diseases.
- Producing pharmacological proteins using transgenic animals as bioreactors.
Importance of Biotechnology
- Developments in biotechnology focus on creating products that improve human health, including biotech drugs, diagnostic tools, and vaccines.
- It plays a crucial role in reducing disease transmission and has applications in forensics through DNA profiling.
Pharmaceutical Biotechnology Products
- Antibodies, produced by white blood cells, help the immune system identify and combat foreign substances.
- Proteins, composed of amino acids, are essential for the structure and function of body tissues and organs.
- Recombinant DNA products involve genetically engineered DNA created by recombining DNA fragments from different organisms.
