Keywords
馃挕RNA
RNA, or ribonucleic acid, is a molecule that plays a crucial role in various biological roles in the coding, decoding, regulation, and expression of genes. In the context of the video, it is the focus of the scientists' research, where they work on understanding its inflammatory properties and eventually developing non-inflammatory RNA for vaccine applications. The script mentions 'I was working with RNA' and 'We started working on RNA, to try and understand why it was so inflammatory.'
馃挕Immunology
Immunology is the study of the immune system, which includes the identification of pathogens, the immune response, and the development of immunity. In the video, one of the speakers learns immunology from the other, highlighting the interdisciplinary nature of their research. The term is exemplified in the script where it says 'I learned all of the immunology from you.'
馃挕Inflammatory
Inflammation refers to the body's response to harmful stimuli, such as pathogens or damaged cells. In the script, the scientists are interested in the inflammatory properties of RNA and how to modify it to be non-inflammatory for vaccine development. The script states 'why it was so inflammatory' and 'how to make it non-inflammatory.'
馃挕Vaccine
A vaccine is a biological preparation that provides active acquired immunity to a particular infectious disease. The video discusses the development of new vaccines, particularly mRNA vaccines, which are a novel type of vaccine that uses a small piece of the pathogen's genetic material to stimulate an immune response. The script mentions 'making new vaccines' and 'different mRNA vaccines.'
馃挕mRNA vaccines
mRNA vaccines are a type of vaccine that uses a small piece of the pathogen's mRNA to instruct cells to produce a protein that triggers an immune response. The video emphasizes the development and success of mRNA vaccines, especially in the context of the COVID-19 pandemic. The script refers to 'mRNA vaccines' and 'an influenza vaccine, which was an mRNA vaccine.'
馃挕Phase 1 clinical trials
Phase 1 clinical trials are the initial stage of testing a new medical intervention in a small group of people to evaluate safety, dosage, and side effects. The video mentions that the scientists were working on five Phase 1 clinical trials of different mRNA vaccines before the COVID-19 pandemic, indicating the early stages of vaccine development. The script states 'We had five Phase 1 clinical trials of different mRNA vaccines.'
馃挕Pandemics
A pandemic is an outbreak of a disease that occurs over a wide geographic area and affects an exceptionally high proportion of the population. The video discusses the scientists' initial goal of developing vaccines, which later became crucial in the context of pandemics, particularly COVID-19. The script mentions 'We weren't thinking about curing pandemics.'
馃挕Gene therapy
Gene therapy involves altering the expression of genes or introducing new genetic material into a patient's cells to treat or prevent disease. In the video, the speaker mentions working on gene therapy for sickle cell anemia, indicating the broad application of their research beyond vaccines. The script says 'sickle cell anemia gene therapy.'
馃挕Infectious diseases
Infectious diseases are illnesses caused by pathogens such as bacteria, viruses, parasites, or fungi. The video highlights the scientists' work on a wide range of infectious diseases, including developing vaccines for various conditions. The script mentions 'We're working on really every imaginable infectious disease.'
馃挕Collaboration
Collaboration refers to the act of working together, especially in an intellectual endeavor. The video emphasizes the importance of the scientists' collaboration, highlighting how their different perspectives and expertise contributed to their research. The script describes their joint efforts in 'We worked together a lot' and 'We couldn't have come to the result without both of us being involved.'
馃挕Scientific discovery
Scientific discovery involves making new observations, identifying new patterns, and developing new theories or applications of knowledge. The video portrays the excitement and joy of scientific discovery, particularly in the context of RNA research and its applications. The script captures this with 'And I鈥檓 so glad that it eventually helps humanity' and 'And I was always interested about this fragile molecule, this RNA.'
