What do cytokines have the potential to do?

• A. Initiate tissue destruction and bone loss in chronic inflammatory disease (e.g., periodontitis)
• B. Promote tissue healing
• C. Increase blood glucose
• D. Directly kill pathogens

Answer: (A)

Cytokines are signaling proteins that regulate and coordinate inflammation and immune responses. In chronic inflammatory diseases like periodontitis, they can drive tissue destruction and bone loss by promoting osteoclast activation through pathways such as RANKL and by upregulating matrix metalloproteinases that break down the extracellular matrix. While cytokines can also support healing in other contexts, the persistent inflammatory environment in conditions like periodontitis tends to cause damage rather than repair, making tissue destruction and bone loss a prominent outcome. They don’t directly kill pathogens; instead, they recruit and activate immune cells that carry out antimicrobial actions, with the tissue damage arising from prolonged inflammatory signaling.
