A new cell model could help kids and teens with arthritis

arthritis: A disease that causes painful inflammation in the joints.

cell: (in biology) The smallest structural and functional unit of an organism. Typically too small to see with the unaided eye, it consists of a watery fluid surrounded by a membrane or wall. Depending on their size, animals are made of anywhere from thousands to trillions of cells. Most organisms, such as yeasts, molds, bacteria and some algae, are composed of only one cell.

chronic: A condition, such as an illness (or its symptoms, including pain), that lasts for a long time.

expression: (in genetics) The process by which a cell uses the information coded in a gene to direct a cell to make a particular protein.

gene: (adj. genetic) A segment of DNA that codes, or holds instructions, for a cell’s production of a protein. Offspring inherit genes from their parents. Genes influence how an organism looks and behaves.

juvenile: Young, sub-adult animals. These are older than “babies” or larvae, but not yet mature enough to be considered an adult.

model: A simulation of a real-world event (usually using a computer) that has been developed to predict one or more likely outcomes. Or an individual that is meant to display how something would work in or look on others.

persevere: To work toward something in the face of adversity or persistent failures.

protein: A compound made from one or more long chains of amino acids. Proteins are an essential part of all living organisms. They form the basis of living cells, muscle and tissues; they also do the work inside of cells. Antibodies, hemoglobin and enzymes are all examples of proteins. Medicines frequently work by latching onto proteins.

Science Talent Search: An annual competition created and run by Society for Science. Begun in 1942, this event brings 40 research-oriented high school seniors to Washington, D.C. each year to showcase their research to the public and to compete for awards. Since spring 2016, this competition has been sponsored by Regeneron Pharmaceuticals.

Society for Science: A nonprofit organization created in 1921 and based in Washington, D.C. Since its founding, the Society has been promoting not only public engagement in scientific research but also the public understanding of science. It created and continues to run two renowned high-school science competitions: the Regeneron Science Talent Search (begun in 1942) and the Regeneron International Science and Engineering Fair (created in 1950). A third, middle-school competition, launched in 2010, has since 2023 been known as the Thermo Fisher Scientific Junior Innovators Challenge. The Society also publishes award-winning journalism: in Science News (launched in 1922) and Science News Explores (created in 2003).

symptom: A physical or mental indicator generally regarded to be characteristic of a disease. Sometimes a single symptom — especially a general one, such as fever or pain — can be a sign of any of many different types of injury or disease.
