Figure Lengend Snippet: FIGURE 1. DNA vaccination-based anti-IL-27 Abs are highly specific. The Western blot shows that our DNA vaccination-based anti-IL-27 Ab binds mouse IL-27 p28 (lane 1; 27 kDa), but not recombinant mouse IL-18, IL-12, or TNF- (lanes 2, 3, and 4, respectively). A, Coomassie Blue staining verifies the appearance of each cytokine on the loaded gel. B, Western blot showing that of these cytokines, our DNA vaccination-based anti-IL-27 Ab binds only mouse IL-27 p28. These Ab also bound natural mouse IL-27 (verified by sequencing) from supernatant of activated MOGp35–55-specific cultured primary draining lymph node cells (not shown).

Article Snippet: Our recombinant mouse IL-27 p28, produced as described above, and commercially available recombinant mouse IL-18, IL-12, and TNF- (R&D Systems) were each subjected to Western blot analysis according to the protocol described in detail previously (29, 32), with the minor modification of using a 12% (rather than 8%) running gel.

Figure Lengend Snippet: FIGURE 2. Anti-p28 Abs suppresses ongoing severe EAE. A, Four groups of 10 mice each were subjected to MOGp35–55-induced EAE. Beginning at the onset of disease (day 17), these mice were repeatedly (every other day) administered 100 g/mouse of anti-p28 Ab (f), IgG obtained from naive Lewis rats (Œ), or PBS (E). An observer blind to the experimental procedure scored EAE daily. The experiment summarized in Fig. 2 shows the results of one of three experiments performed under similar experimental conditions, with similar results. The mean maximal score SE represents six mice per group. The other four mice were killed on day 30 and subjected to histological evaluation (see Fig. 3). B, Five groups of six mice each were subjected to MOGp35–55-induced EAE. Beginning at the onset of disease (day 17), these mice were repeatedly (every other day) administered 100 g of anti-p28 Ab/mouse (f), anti-IL-18 Ab (F), anti-IL-1 Ab (), IgG obtained from Lewis rats previously subjected to an empty plasmid administration (Œ), or PBS (E). An observer blind to the experimental procedure scored EAE daily. Results are shown as the mean maximal score SE of six mice per group. C, Three groups of six mice each were subjected to induction of transferred EAE. Beginning at the onset of disease (day 5), these mice were repeatedly (every other day) administered 100 g of anti-p28 Ab/mouse (f), IgG obtained from naive Lewis rats (Œ), or PBS (E). An observer blind to the experimental procedure scored EAE daily. Results are shown as mean maximal score SE of six mice per group.

Figure Lengend Snippet: FIGURE 4. The beneficial effect of anti-IL-27 is dependent on the con- tinuing administration of protective Abs. Three groups of six mice each were subjected to active induction of EAE. Beginning 1 day after the onset of disease (day 17), these mice were treated with either a single dose of anti-p28 Ab (100 g/mouse; E) or with repeated administration (every other day) of this Ab (Œ) or PBS (f). An observer blind to the experi- mental procedure scored EAE daily. Results are shown as the mean max- imal score SE of six mice per group.

Figure Lengend Snippet: FIGURE 3. Anti-IL-27 therapy reduces the histological score of EAE. Histological evaluation was conducted 30 days after disease induction. Lumbar spinal cord samples from naive mice or from EAE mice treated with PBS, IgG from naive mice, or anti-IL-27 p28 Abs were subjected to histological analysis (nine sections each group). The arrowheads point to the parenchymal mononuclear cell infiltration. The scale for mononuclear cell infiltration used was: 0, no mononuclear cell infiltration; 1, one to five perivascular lesions per section with minimal parenchymal infiltration; 2, five to 10 perivascular lesions per section with parenchymal infiltration; and 3, 10 perivascular lesions per section with extensive parenchymal infiltration. The mean histological score SE was calculated for each group.

Figure Lengend Snippet: FIGURE 5. Protective administration of anti-IL-27 Abs decreases in vivo polarization of CD4 T cells into Th1 and suppresses IFN- production by Ag-specific T cells. C57BL/6 mice (three per group) were subjected to active induction of EAE and then to repeated administration (days 12, 14, and 16) of anti-IL-27 p28 Abs (100 g), PBS, or normal rat IgG. On day 17 cervical lymph node cells (that drain the autoimmune site) were subjected to intracellular staining of IL-4 and IFN-. A, FACS analysis of CD4 T cells in this experiment. This experiment represents results obtained in three different independent experiments with very similar data. Subsequently, cervical lymph node T cells from these mice were cultured in the presence of 100 M MOGp35–55. After 72 h of stimulation, supernatants were assayed for the protein level of IFN- (B) and IL-4 (not shown). This experiment represents results obtained in three different independent experiments with very similar data.

A, C57BL/6 mice (three per group) were subjected to active induction of EAE and then to repeated administration (days 3 and 6) of 100 g of anti-IL-27 p28 Abs (group 3), PBS (group 2), or normal rat IgG (group 1). On day 9, spleen cells were subjected to spot ELISA as previously described (38). A, Relative number of positive spots per 107 cultured cells. The average size of positive spots was analyzed. B, The MOGp33–55-specific CD4 T cell line was cultured with or without 100 M MOGp33–55. Cultured cells were supplemented with anti-IL-27 Abs at a final concentration of 10 g/ml (), normal rat IgG (f), or PBS (E). After 60 h of incubation, cells were plates in spot ELISA plates for an additional 24 h for the detection of IFN--positive spots (38). Number of positive spots (y-axis) and spot sizes (x-axis; logarithmic scale) determined as previously described (46).

Microglia Require Opn-i Expression to Induce Th17 Cells Opn-deficient microglia were infected with lenti-Opn-i or lenti-GFP and incubated 2D2+CD4 T cells and MOG peptide. (A and B) Reconstitution of Opn-deficient microglia with Opn-i rescues IL-17 production by CD4+ 2D2 T cells.

The amounts of IL-27p28 were determined by ELISA in triplicate wells; empty and filled bars denote supernatants from Opn-i-transfected and GFP-transfected DC, respectively, and data are representative of two experiments. (C) EAE development is inhibited in irradiated Opn-deficient hosts. Total BM cells (1.7 3 107 cells/mouse) from 2D2+ Tg Opn-deficient mice were i.v. trans- ferred to irradiated (800 rads) hosts. Ten weeks later, EAE was induced. Disease development (mean clinical score) and incidence (%) is shown for each group (n = 5). Error bars in disease score denote mean ± SEM and t test values on the last day of observation are shown.
