Cellular response is a research area that focuses on understanding how cells respond to various stimuli, such as changes in their environment, signaling molecules, or pathogens. This field of study investigates the molecular mechanisms and pathways involved in cell signaling, gene expression, and other cellular processes that dictate how cells adapt and react to external stimuli. By studying cellular responses, researchers aim to uncover key insights into diseases, drug interactions, and other biological processes that can be targeted for therapeutic interventions.
