Inflammation is a biological response of the body to harmful stimuli, such as pathogens, damaged cells, or irritants. It is a protective mechanism to remove the stimulus and initiate the healing process. Inflammation is characterized by redness, swelling, heat, and pain in the affected area. Chronic inflammation has been implicated in a variety of diseases, including arthritis, cardiovascular disease, and cancer. Research in the field of inflammation focuses on understanding the molecular mechanisms underlying the inflammatory response and developing therapeutic strategies to modulate it. This research area involves a multidisciplinary approach, combining expertise in immunology, molecular biology, and pharmacology.
