Study Notes
Introduction to Biotechnology
- This class is designed to provide a broad view of the biotechnology industry, covering important aspects from molecular biotechnology and receptor pharmacology to regulatory affairs and drug development.
- The course integrates multiple disciplines, including process engineering, chemistry, and business.
- Knowledge gained from this class can be applied in real life professions.
Instructor and Course Details
- The instructor has a PhD in Molecular Genetics and Biotechnology.
- He has worked in academia, government, and the biotechnology industry.
- He is currently an Associate Teaching Professor and Faculty Lead in Biotechnology at Northeastern University.
Course Requirements
- Attendance is mandatory and may affect your grade.
- You must notify the instructor if you miss a class before it starts.
- Assignments require accurate and concise language and are due at the start of the following class.
Biotechnology and COVID-19 Vaccines
- COVID-19 vaccines target the spike protein of the SARS-CoV-2 virus.
- The development process was accelerated by previous research, faster manufacturing methods, and significant funding.
- Vector vaccines and mRNA vaccines are two primary types of COVID-19 vaccines.
Drug Development
- Preclinical testing determines the safety of a drug for human trials.
- Enzyme kinetics plays a crucial role in drug development, with factors like temperature and pH influencing enzyme activity.
- Competitive inhibitors slow down product formation by competing with the substrate for the enzyme's active site.
- Noncompetitive inhibitors bind to a different site on the enzyme, changing the shape of the active site and potentially affecting the protein's stability.
- Protein-protein interactions (PPIs) are important targets for drug development, especially in areas like cell signaling and growth.
- Good Manufacturing Practices (GMP) and Good Laboratory Practices (GLP) regulate safety studies for drugs, including mRNA vaccines.
Impact of the COVID-19 Pandemic on Biomedical Research
- The National Academy of Medicine outlined several priorities for COVID-19 response, including investing in research, accelerating diagnostic testing, building public-private partnerships, and ensuring access to treatment and prevention measures for all populations.
Monoclonal Antibodies (mAbs)
- mAbs are antibodies that target a specific antigen.
- mAb development has progressed from murine (derived from mice) to humanized and fully human antibodies, providing better safety profiles and reducing the risk of immune rejection.
- Hybridoma technology combines a short-lived antibody-producing B cell with an immortal myeloma cell to create a hybrid cell that produces antibodies indefinitely.
Ethical Considerations in Research: The Tuskegee Syphilis Study
- The Tuskegee Syphilis Study, conducted from 1932 to 1972, involved withholding treatment from Black men with syphilis to study the disease's progression.
- It is considered a major example of unethical research practices, contributing to the development of informed consent regulations.
Biotherapeutic Development Roadmap
- The development of biotherapeutics includes preclinical (IND), clinical trial (IND), and post-approval (NDA/BLA) phases.
- The different phases involve comprehensive testing for safety, efficacy, and regulatory clearance.
Final Group Project
- The final group project will be an opportunity to apply acquired knowledge to real-world biotechnology applications in areas like research and commercialization.
