cDNA cloning of biologically active chicken interleukin-18.

By searching a chicken EST database, we identified a cDNA clone that appeared to contain the entire open reading frame (ORF) of chicken interleukin-18 (ChIL-18). The encoded protein consists of 198 amino acids and exhibits approximately 30% sequence identity to IL-18 of humans and various others mammals. Sequence comparisons reveals a putative caspase-1 cleavage site at aspartic acid 29 of the ...

Production of a biologically active human interleukin 18 requires its prior synthesis as PRO-IL-18.

Interleukin (IL-)18 is an activator of NK cells and a co-inducer of Th(1)cytokines, sharing structural features with the IL-1 family of proteins. Unlike most other cytokines, IL-18 and IL-1beta lack a signal peptide, have an all beta-pleated sheet structure and are synthesized as biologically inactive precursors (pro-IL-18 and pro-IL-1beta). These precursors are cleaved by caspase-1 (IL-1beta-c...

Cloning and Expression of Mature Chicken Interleukin- 18 Using Live Attenuated Salmonella Enterica Serovar Typhimurium

Cytokines play pivotal roles as natural mediators and regulators of the immune response [1] and therefore may offer exciting new alternatives over existing conventional control measures which include combined use of vaccines, antibiotics and chemicals. The utilization of chicken cytokines in poultry disease prevention is becoming more promising with the growing list of new cytokines [2]. Interl...

Identification and characterization of chicken interleukin-16 cDNA.

Interleukin-16 is an inflammatory cytokine synthesized as a precursor protein (pro-IL-16). Based on sequence data from an EST cDNA library prepared from intestinal intraepithelial lymphocytes of Eimeria-infected chickens, we identified a cDNA that contained a full-length open reading frame of pro-IL-16. The encoded protein, predicted to consist of 607 amino acids, showed 86% sequence identity t...

Chicken ghrelin: purification, cDNA cloning, and biological activity.

In this study, we report the purification, cDNA cloning, and characterization of the novel growth hormone-releasing peptide, ghrelin, in the chicken (Gallus gallus). Chicken ghrelin is composed of 26 amino acids (GSSFLSPTYKNIQQQKDTRKPTARLH) and possesses 54% sequence identity with human ghrelin. The serine residue at position 3 (Ser(3)) is conserved between the chicken and mammalian species, as...
