摘要: Novel polypeptides having a modified amino acid sequence of human interleukin 1.alpha. polypeptides in which a certain amino acid residue(s) in said amino acid sequence is(are) exchanged for other amino acid residue(s). Said polypeptides having no capacity of induction of production of prostaglandin E.sub.2 while maintaining other biological activities of human interleukin 1 such as activation of lymphocyte and being expected to be useful as a medicament.

摘要: A human TNF polypeptide mutant having an amino acid sequence of modified human TNF polypeptide, a DNA having a base sequence encoding the above human TNF polypeptide mutant and a method of producing the above human TNF polypeptide mutant by culturing a host transformed with a vector having inserted therein the above DNA. The above human TNF polypeptide mutant is soluble and has antitumor activity.
