Inflammation is a complex biological response triggered by harmful stimuli such as pathogens, damaged cells, or irritants, and is essential for the body’s defence and healing processes. Effective modulation of inflammation is crucial for maintaining health, as both insufficient and excessive inflammatory responses can lead to disease. Various endogenous and exogenous factors, including cytokines, immune cells, pharmacological agents, and lifestyle choices, play pivotal roles in modulating inflammation. Endogenous modulators include cytokines, which are small proteins acting as key signalling molecules in the inflammatory response. Proinflammatory cytokines such as tumour necrosis factor-alpha (TNF-α), interleukin-1 (IL-1), and interleukin-6 (IL-6) initiate and propagate inflammation by promoting the recruitment of immune cells to the site of injury or infection and enhancing the production of other inflammatory mediators. These cytokines are essential for combating infections and facilitating tissue repair. Conversely, anti-inflammatory cytokines such as interleukin-10 (IL-10) and transforming growth factor-beta (TGF-β) help resolve inflammation by inhibiting the production of pro-inflammatory cytokines and promoting tissue repair and regeneration. Immune cells also play significant roles in modulating inflammation. Macrophages, for instance, can adopt different activation states depending on the signals they receive. The M1 phenotype is pro-inflammatory and microbicidal, producing large amounts of reactive oxygen species and pro-inflammatory cytokines to combat pathogens. Neutrophils are another key immune cell type involved in the initial response to infection, releasing enzymes and reactive oxygen species to kill pathogens. However, their activity must be tightly regulated to prevent excessive tissue damage. Regulatory T cells (Tregs) help control the inflammatory response and prevent autoimmunity by suppressing excessive immune activation. Exogenous modulators include pharmacological agents such as non-steroidal anti-inflammatory drugs (NSAIDs) and corticosteroids. NSAIDs, like aspirin and ibuprofen, inhibit the enzyme Cyclooxygenase (COX), which is involved in the synthesis of pro-inflammatory prostaglandins. By reducing prostaglandin production, NSAIDs decrease inflammation, pain, and fever. However, chronic use of NSAIDs can lead to gastrointestinal issues and other side effects. Corticosteroids are potent anti-inflammatory agents that mimic the effects of endogenous glucocorticoids. They work by inhibiting multiple inflammatory pathways, including the suppression of cytokine production, inhibition of leukocyte recruitment, and stabilization of cell membranes. While effective, longterm use of corticosteroids can result in significant side effects, including immunosuppression, osteoporosis, and metabolic disturbances. Biologic agents, such as monoclonal antibodies and receptor antagonists, have been developed to target specific components of the inflammatory process. For example, anti-TNF-α drugs (e.g., infliximab and adalimumab) are used to treat autoimmune diseases like rheumatoid arthritis and Crohn’s disease by neutralizing the activity of TNF-α. Interleukin-1 receptor antagonists (e.g., anakinra) and interleukin-6 receptor inhibitors (e.g., tocilizumab) are also used to modulate inflammation in various inflammatory conditions. Lifestyle and dietary factors can significantly impact inflammation.
