Type I helper cells secrete:
A. Interleukin-lB. Interleukin-2
C. Interleukin-4
D. Interleukin-5
Ans. (b) IL -2
• Interleukins are “cytokines”.
• Proteins of usually low molecular weight.
• Regulating important biological processes.
• Interleukins are produced by Monocytes, Macrophages, B and T Lymphocytes, mast cells, neutrophils.
IL1 causes fever
IL2 T cell stimulation
IL3 Bone Marrow stimulation
IL4 IgE Stimulation
IL5 IgA Stimulation
