Cellular stress response is a field of research that focuses on understanding how cells react to various external and internal stressors, such as heat, toxins, oxidative damage, or nutrient deprivation. This response involves a complex network of signaling pathways and molecular mechanisms that help cells adapt to and survive under stressful conditions. Cellular stress response plays a critical role in maintaining cellular homeostasis and preventing damage that can lead to diseases such as cancer, neurodegenerative disorders, and autoimmune disorders. Studying cellular stress response can provide insights into disease mechanisms and potential therapeutic targets for developing treatments to alleviate stress-related pathologies.
