Dataset on characterization of recombinant interleukin-23α, IL-12p40 and IL-23 complex protein, which activates JAK-STAT signaling pathway in chicken cell lines using immunocytochemical staining.

The data herein is related to the research article entitled "Functional analyses of the interaction of chicken interleukin 23 subunit p19 with IL-12 subunit p40 to form the IL-23 complex" [1] where we demonstrated that the chicken interleukin (IL)-23α, IL-12p40, and IL-23 complex regulates Th1, Th17, and Treg cytokine production through heterodimer receptors as well as a homodimer receptor consisting of IL-12Rβ1 and IL-23R, and activates the JAK/STAT signaling pathways. Here, we evaluated the effects of the recombinant chicken IL-23α, IL-12p40, and IL-23 complex protein on cell proliferation and nitric oxide (NO) production in chicken macrophage (HD11) and CU91 T cell lines. In addition, the expression of IL-6, IL-17A, and interferon-γ mRNA were upregulated in vivo and in vitro. Moreover, treatment with the chicken IL-23α, IL-12p40, and IL-23 complex activated phosphorylation of tyrosine and serine residues in JAK2, STAT1, TYK2, and SOCS1 in chicken cell lines.

Value of the data

The data is valuable for the expression of pro-inflammatory molecules in chicken cell lines treated with DMSO and LPS and various tissues of chicken following S. enteritidis infection.

The data is a contribution to the effect of chicken IL-23α, IL-12p40, IL-12p40 + IL-23α, and IL-23 complex protein to cell proliferation and production of reactive oxygen species in the form of NO in chicken cell lines.

The data provided the expression of JAK-STAT signaling molecules by chicken IL-23α, IL-12p40, IL-12p40 + IL-23α, and IL-23 complex protein stimulation in chicken cell lines.

Data

The dataset in this article provides additional information to Ref. [1], where we demonstrated that the chicken IL-23α, IL-12p40, and IL-23 complex activated multiple signaling pathways through heterodimer receptors, as well as a homodimer receptor consisting of IL-12Rβ1 and IL-23R, and induced Th1, Th17, and Treg cytokine production. In this dataset, we provided the nucleotide and amino acid sequences of the chicken IL-23α coding region (Fig. 1A). These proteins were observed as single bands at 34 kDa (ChIL-23α), 48 kDa (ChIL-12p40- G10S3 linker), and 68 kDa (ChIL-23 complex) (Fig. 1B) by western blotting using the horseradish peroxidase (HRP)-anti-His (C-Term) antibody (Invitrogen, Carlsbad, CA, USA). The size was larger than predicted because of the presence of 3 epitope tags (polyhistidine, S-protein, and thioredoxin) in the recombinant protein. Moreover, data provides information about the effect of chicken IL-23α, IL-12p40, and IL-23 complex protein on cell proliferation and production of reactive oxygen species in the form of NO in both cell lines (Fig. 1C–D). In addition to the dataset, we present the expression of IL-6, IL-17A, and interferon (IFN)-γ mRNA in chicken cell lines treated with dimethyl sulfoxide (DMSO) and lipopolysaccharide (LPS) and in various tissues of the chicken following Salmonella Enteritidis infection (Fig. 2). Finally, immunocytochemical analysis showed that the expression of JAK-STAT signaling molecules by IL-23α, IL-12p40, and IL-23 complex stimulation in the chicken cell lines (Fig. 3, Fig. 4).
