Cells responsible for producing interleukins.

Interleukins are produced by various types of immune cells, including:

1. T lymphocytes (T cells)
2. B lymphocytes (B cells)
3. Macrophages
4. Dendritic cells
5. Mast cells
6. Natural killer (NK) cells

These cells play a crucial role in the immune response by producing interleukins, which are signaling molecules that help regulate and coordinate the immune system's response to infections and other challenges.
