What is the Difference Between Interleukin 1 and 2?
🆚 Go to Comparative Table 🆚Interleukin 1 (IL-1) and Interleukin 2 (IL-2) are both cytokines, but they have distinct roles and characteristics. The main differences between IL-1 and IL-2 include:
- Function: IL-1 is a family of cytokines with strong pro-inflammatory effects, while IL-2 is a cytokine signaling molecule that promotes the growth and differentiation of immune cells.
- Receptors: IL-1 binds to IL-1 receptors, while IL-2 binds to IL-2 receptors.
- Producing Cells: IL-1 is secreted by various cell types, including macrophages, large granular lymphocytes, B cells, endothelium, fibroblasts, and astrocytes. In contrast, IL-2 is secreted by T cells.
- Structure: IL-1 is a family of 11 cytokines, while IL-2 is a single cytokine.
In summary, IL-1 and IL-2 are both involved in the immune response, but they have different functions and bind to different receptors. IL-1 is primarily pro-inflammatory, while IL-2 promotes the growth and differentiation of immune cells.
Comparative Table: Interleukin 1 vs 2
Interleukin 1 (IL-1) and Interleukin 2 (IL-2) are cytokine signaling molecules involved in the immune system, playing crucial roles in immunity. They are both proteins, but they have distinct functions and receptors:
Feature | Interleukin 1 | Interleukin 2 |
---|---|---|
Function | Comprises a family of 11 cytokines responsible for various immune responses | Promotes the growth and differentiation of immune cells |
Receptors | Binds with IL-1 receptors | Binds with IL-2 receptors |
Secretion | Secreted by macrophages, large granular lymphocytes, B cells, endothelium, fibroblasts, and astrocytes | Secreted by T cells |
IL-1 and IL-2 have different physiological functions and pathological significances, playing essential roles in the immune system.
