Interleukin

 Name
Source  
Target Receptor  
Target Cells 
Functions 
Recent Research 





Interleukin 1



Macrophages, 
B cells, Monocytes, Dendritic Cells 




CD121a/IL1R1, CD121b/ILR2 
T helper cells 
Co-stimulation

B cells
Maturation & Proliferation 

NK cells
 Activation

Macrophages, endothelium or other  
Inflammation, small amount induce acute phase reaction, large amounts induce fever
IL-1 can itself produce hyperalgesia as assessed by tailflick to radiant heat  
Interleukin 2  
Th - 1 Cells  
CD25/IL2RA, CD122/IL2RB, CD132/IL2RG 
Activated T cells, B cells, NK cells, macrophages, oligodendrocyte 
- Stimulate growth and differentiation of T cell response. 
- Can be used in immunotherapy to treat cancer or suppressed or transplant patients 
High dose IL-2 produce durable responses in some patients with metastatic melanoma and should be considered a therapeutic option for appropriately selected patients with his disease.
IL-2 released by lung T Cells in inactive pulmonary sarcoidosis   
Interleukin 3
Activated T helper cells, mast cells, NK cells, endothelium, eosinophils 
CD123/IL3RA, CD131/IL3RB 
Hematopoietic stem cells  
Differentiation and proliferation of myeloid progenitor cells Eg - erythrocytes & granulocytes 
IL-3 supports growth of mouse pre B Cell clones in-vitro.  
Mast cell 
Growth & histamine release

Interleukin 4 
Th - 1 cells, activated naive CD4+ cell, memory CD4+ cells, mast cells, macrophages  
CD124/IL4R, CD132/IL2RG 
Activated B cells 
Proliferation & differentiation, Ig G1 and Ig E synthesis.
Important role in allergic response (Ig E)
Systemic sclerosis  
T cells
Proliferation  

Interleukin 5 
Th -2 cells, mast cell, eosinophils  
CD125/IL5RA, CD131/IL3RB 
Eosinophils  
Production

B Cells 
Differentiation, Ig A production 

Interleukin 6 
Macrophages, Th - 2 cells, B cells, astrocytes, endothelium  
CD126/IL6RA, CD130/IL6RB 
Activated B cells 
Differentiation into plasma cells 

Plasma cells 
Antibody secretion 

Hematopoietic stem cells
Differentiation 

T Cells or Other 
Induce acute phase reaction, hematopoiesis, differentiation, inflammation 

Interleukin 7 
Bone marrow, stromal cells & thymus stromal cells 
CD127/IL7RA, CD132/IL2RG 
Pre/pro- B cell, Pre/pro- T cell, NK cells 
Differentiation and proliferation of lymphoid progenitor cells, involved B, T and NK cells survival, development and homeostasis, increase pro-inflammatory, cytokine      
Show effect on T cells homeostasis
