Analysing lymphokine-receptor interactions of IL-1 and IL-2 by recombinant-DNA technology. 
The development of lymphokines as pharmaceutical agents is at the forefront of current biotechnological research.  Lymphokines exert their regulatory action on cellular function through interaction with cell-surface receptors.  An understanding of the biochemical nature of these molecular interactions should facilitate the design of small peptide analog pharmaceuticals which mimic lymphokines or their receptors.
