摘要

The cDNAs for four rabbit cytokine genes [interleukin 2 (IL-2), IL-4, IL-6 and IL-10] have been cloned from primary lymphocytes by polymerase chain reaction (PCR) methods. IL-2 and IL-10 are both highly conserved between rabbit and other species. IL-4 and IL-6 are less strongly conserved, at both nucleotide and amino acid levels, and exhibit structural differences. An extension of the coding region of rabbit IL-6 relative to all other reported IL-6 genes results from a mutation in the usual stop codon which allows translation to continue for a further 27 amino acids. Analysis of IL-6 from four other lagomorph species suggests that this mutation is specific to the European rabbit. Sequence and structural differences of IL-4 and IL-6, while presumably not altering function, may render them highly species-specific. Several alternatively spliced variants of IL-2 and IL-4 are also reported. Copyright 2000 Academic Press.
