Final answer:
Substances released by damaged cells, such as cytokines and chemokines, play a crucial role in signaling immune responses and inflammation and can be targeted in medical treatments.
Step-by-step explanation:
The substance released by damaged cells that acts like a signal for an immune response or inflammation is called a cytokine. When cells are injured, they release cytokines as well as other types of signaling molecules, such as calcium ions. This release triggers an electrochemical response that promotes the healing process. For example, physiologists at Vanderbilt University demonstrated that cells release different chemicals based on the type of damage incurred, which is crucial for the organism to initiate the appropriate healing response.
Chemokines are a specific type of cytokines known as chemotactic cytokines that attract leukocytes to sites of injury, infection, or inflammation. Furthermore, in the advancements of medical treatments, targeted delivery systems have been developed that can carry toxic substances to cancerous cells, using the principle that cells have specific receptors for substances, allowing for more precise treatments without harming surrounding cells.
Understanding these processes is essential in the realm of medicine for treating hormonal disorders, attacking cancerous cells, and fostering recovery from injuries through improved healing mechanisms.
