IFN GAMMA, Monoclonal Antibody

Published customer image: Identification of recombinant antibodies with specificity for bIL-2. PBMC from a cow naturally infected with M. bovis were cultured in the presence of PPD-B to allow screening of candidate bIL-2 by ICS flow cytometry. Panel A shows the histogram gating strategy used to interrogate responses in singlet, live CD4+ lymphocytes. Panel B shows the measurement of detectable IL-2 and/or IFN- gamma within the CD4+ population for each of 6 candidate IL-2 antibody clones. The clone number is shown in the top left corner of each histogram and the percentage of CD4+ cell in which co-expression of IFN- gamma and IL-2 could be detected is shown in the top right of each histogram. Data are representative of 1 of 2 independent experiments.From: Whelan AO, Villarreal-Ramos B, Vordermeier HM, Hogarth PJ (2011) Development of an Antibody to Bovine IL-2 Reveals Multifunctional CD4 TEM Cells in Cattle Naturally Infected with Bovine Tuberculosis.

Published customer image: Comparative IL-12 and IFN&gamma responses of neonatal and ***** MLN cells following TLR agonist stimulation. Neonatal (closed circles) and ***** (open squares) MLN cells were cultured in vitro with or without 12.5 ug/ml polyI:C, 0.5 ug/ml R-848 or 5 ug/ml Gardiquimod. Supernatants were harvested after 48 h of culture and ELISA was carried out for IL-12 (A) and IFN? (B) secretion. Non-specific cell stimulation was also carried out with 50 ng/ml PMA combined with 500 ng/ml ionomycin, with the supernatants assayed for IFN? detection 48 h later (C). Each circle or square represents one neonate or one *****, respectively. Medians are shown for each stimulus. Non-parametric Mann-Whitney tests were used to compare data for neonates and *****s: *p=0.01; **p=0.005; ***p=0.001; ****p=0.0005.From: Ferret-Bernard S, Remot A, Lacroix-Lamand© S, Metton C, Bernardet N, et al.

Published customer image: gamma delta T cells require TNF-alpha to protect against B. abortus infection. C57BL/6 mice treated with anti-TCR gamma delta mAb or hamster IgG on day -1 and day 3 post-infection with 5x104 CFUs of B. abortus 2308. Some mice were also neutralized of their TNF-alpha on days -1 and 3. Seven days after infection, A. splenic weights and B. extent of brucellae colonization were determined. The mean +/- SEM of 10 mice/group is depicted; *P

Published customer image: Bovine gamma delta T cells impair B. abortus replication in autologous macrophages via IFN- gamma . A. -F. Bovine macrophages were infected with B. abortus (30 bacteria:1 macrophage) and then fresh media or media containing autologous gamma delta T cells were added to infected macrophages. A., C., E. Macrophage colonization (triplicate wells/treatment) was monitored over time. *P

Published customer image: B. abortus infection does not induce IL-17 or IFN- gamma production by gamma delta T cells. A. Splenocytes from na¯ve or B. abortus-infected mice (7 dpi) were stimulated overnight with PMA/Ionomycin and brefeldin A was added for the last 3 h of culture. Following surface staining, cells were permeabilized and stained for intracellular IL-17 or IFN-?. Top panel, the proportion of IL-17 producing gamma delta T cells was determined following gating on lymphocytes. Second panel from top, cells were gated on CD4+ (CD3+) T cells and assayed for IL-17 production. Third panel from top, cells were gated on gamma delta T cells (CD3+/TCR gamma delta +) and assayed for IFN- gamma production. Bottom panel, cells were gated on CD4+ (CD3+) T cells and assayed for IFN- gamma production. Depicted is the mean +/- SD of 5 mice/group and is representative of two independent experiments. B. gamma delta T cells were sorted from na¯ve or B. abortus-infected (7 dpi) mice and stimulated for 72 h with PMA/Ionomycin. Cytokine levels in supernatant were determined by ELISA. Depicted is the mean +/- SD of triplicate wells. *P

Published customer image: gamma delta T cells are the primary source of IL-17 during B. abortus infection. C57BL/6 mice were infected i.p. with 5x104 CFUs of B. abortus 2308, and two weeks later gamma delta T cells (>95% purity) and an enriched TCRalphabeta (~55% CD4+, 25% CD8+) cell fraction were isolated from the spleens of infected mice. Cells were stimulated with 500 ng/ml ionomycin and 50 ng/ml PMA for three days, and cell-free supernatants from triplicate wells were assayed for cytokine production via ELISA. The mean +/- SD is shown; * P

Produced by lymphocytes activated by specific antigens or mitogens. IFN-gamma, in addition to having antiviral activity, has important immunoregulatory functions. It is a potent activator of macrophages, it has antiproliferative effects on transformed cells and it can potentiate the antiviral and antitumor effects of the type I interferons.
