Cytokines are signaling molecules that mediate and regulate immunity and inflammation. They are produced by various cells, including macrophages, dendritic cells, and T cells. Key cytokines in the local immune response include:
Interleukins: Promote the growth and differentiation of immune cells. Tumor Necrosis Factor (TNF): Involved in systemic inflammation and can induce apoptosis in infected cells. Interferons: Play a role in antiviral defense by inhibiting viral replication. Chemokines: Attract immune cells to the site of infection or injury.
