(A) The frequency of IFN-γ+CD4+ or IFN-γ+CD8+ T cells in lungs. Chickens in groups of five were vaccinated with mock vaccine or SD/01/10-ca on day 0 and challenged intranasally with 106 EID50 of A/chicken/Hebei/YT/2010 on day 14 after vaccination. Lungs were harvested on day 7 after challenge. IFN-γ+CD4+ or IFN-γ+CD8+ T cells in lungs stimulated with SD/01/10-wt were measured. Percentages of IFN-γ+CD4+ or IFN-γ+CD8+ T cells within CD4+ or CD8+ T cells were analyzed. *P <0.05, by one-way analysis of variance of the difference between SD/01/10-ca and mock vaccine group on day 7 after challenge. (B) HI antibody responses to homologous and heterologous viruses after vaccination with SD/01/10-ca. Serum samples were collected on day 14 post immunization, and the reactivity of collected sera (n = 3) to SD/01/10-wt or five heterologous H9N2 influenza viruses was assessed by an HI assay.

Rabbit anti Chicken interferon gamma antibody (AHP945) used for the evaluation of intracellular gamma interferon in chicken lymphocytes by flow cytometry.
Image caption:
Intracellular staining of IFN-γ in transfected CHO cells. A) CHO cells were either transfected with plasmids containing the chicken IFN-γ gene or empty plasmids (mock controls). Cells (day 22 after transfection) were cultured with or without BFA for 18 hours and subsequently stained intracellularly using monoclonal anti-chicken IFN-γ antibody (Mab80) conjugated with APC. Representative samples are shown with frequency of IFN-γ+ cells indicated above gate. B) Comparison of transfected CHO cells (day 30 after transfection) cultured with 10 μg/ml BFA for 18 hours and subsequently stained intracellularly with either commercial ELISA capture antibody (5C.123.08) & A647 conjugated secondary anti-mouse IgG1 or monoclonal anti-chicken IFN-γ antibody directly conjugated with APC (Mab80) or commercial ELISA detection antibody (5C.123.02) directly conjugated with APC or polyclonal rabbit anti-chicken IFN-γ antibody & FITC-conjugated secondary goat anti-rabbit IgG. Representative samples are show with frequency of IFN-γ+ cells indicated above gate.

Rabbit anti Chicken interferon gamma antibody recognizes chicken interferon gamma (chIFN-gamma). There are at least three distinct chicken interferon proteins, designated as chIFN-alpha, chIFN-beta and chIFN-gamma.
chIFN-gamma was first identified, when supernatant from chicken spleen cells stimulated with concanavalin A (ConA ), displayed macrophage-activating factor (MAF) activity - the principle function of mammalian type II IFN-gamma (Vonbulow et al. 1984). Cloning of IFN-gamma cDNA from activated chicken T cells indicates that recombinant chicken IFN-gamma activates macrophages, strongly upregulating the expression of MHC class II and iNOS genes (Weining et al. 1996).
Rabbit anti Chicken interferon gamma antibody can be used to neutralize chIFN-gamma activity and to discriminate the antiviral activity of chIFN-gamma from that of chIFN-alpha and chIFN-beta (Weining et al. 1996).
