[0030] The antibody may be administered at any suitable site and at any suitable time. Preferably, the antibodies are administered simultaneously or substantially simultaneously. They may be administered sequentially or simultaneously, or together as a mixture. [Example]
[0031] [Example 1] Allergy experiments using polyclonal human IMIG and polyclonal human anti-tetanus Ig protocol Five BALB / c mice (8 weeks old at the start of the study) were used per group. All mice (Group 1, see below) received ovalbumin (10 μg OVA plus A l(OH)3) in 0.3 ml of phosphate-buffered saline ("PBS") on day 0. All mice were given a 14-day booster dose intraperitoneally on day 56. From day 1, the mice were given egg white solution (20% (w / v) filtered EWS) in their drinking water.
[0032] Intramuscular immunoglobulin (Gamunex® 25 μg: Grifols) The mice were treated on days 2, 7, 14, 21, 28, and 35. On the 4th and 42nd days, 0.05 ml of PBS was injected intramuscularly into the left gluteal muscle. For animals receiving immune Ig (HyperTET 25μg: Grifols) Then, on days 2, 7, 14, 21, 28, 35, and 42, 0.05 ml of PBS was injected intramuscularly into the right deltoid muscle. G or anti-tetanus was adsorbed with tetanus toxoid (x3) before use. PBS was administered only at the same site.
[0033] The following groups were used: Group 1: OVA - / EWS + Group 2: OVA + / EWS + Group 3: Group 2 + IMIG (OVA) + / EWS + +IMIG) Group 4: Group 2 + anti-tetanus Ig (OVA) + / EWS + +Anti-TetIg) Group 5: Group 2 + IMIG + anti-tetanus Ig (OVA) + / EWS + +IMIG+An ti-TetIg) Group 6: Group 2 + IMIG (treated with tetanus x3 adsorption) + anti-tetanus Ig ( OVA + / EWS + +IMIGAbs+Anti-Tet) Group 7: Group 2 + IMIG + anti-tetanus Ig (treated with tetanus x3) ( OVA + / EWS + +IMIG+Anti-Tetabs)
[0034] All mice were sacrificed on day 63 of the study. At the time of sacrifice, OVs obtained by cardiac puncture were Serum IgE against A was measured using a mouse model of OVA coated with HRP-antimacroglobulin (HRP) at 100 ng / well. The antibody was measured by ELISA using plates developed with mouse IgE and appropriate substrates. Ta.
[0035] Plus 5x10 from individual animals 6 splenocytes were in vitro treated with OVA at 1 μg / ml The cells were exposed to 2 ml of the culture medium for 72 hours, and IL-2 / IL-4 was measured using a commercially available ELISA kit ( Measurements were performed in culture supernatants using eBIOSciences.
[0036] result Figure 1A shows that the combination of IMIG and polyclonal anti-tetanus Ig resulted in a significant increase in OVA-specific Figure 1B shows that OVA-specific IgE was significantly suppressed, and Figure 1B shows that OVA-specific IgG was significantly suppressed. Referring now to Figure 1A, the adsorption of IMIG by tetanus (Group 6) and tetanus treatment with polyclonal anti-tetanus adsorption (Group 7) showed no difference. This suggests that the active pharmaceutical ingredient is not anti-tetanus antibodies.
[0037] Figure 1C shows the results for groups 5, 6, and 7, which received a combination of IMIG and anti-tetanus Ig injections. 1 shows the reduction in OVA-induced IL-4 levels in splenocytes of mice. When considered together with Figure 1D, which shows the IL-4 to IL-2 levels, the ratio of IL-4 to IL-2 was significantly higher in IMIG plus For the groups treated with anti-tetanus Ig (groups 5, 6, and 7), the control groups 2, 3, and 4 This result is clearly smaller than the alleles shown in Figures 1A and 1B. This is consistent with the suppression of ghee and its results.
[0038] [Example 2] Allergy experiments using polyclonal human IMIG and polyclonal human anti-tetanus Ig Experimental Protocol Eight BALB / c mice (8 weeks old at the start of the study) were used per group. All mice were treated with ovalbumin (10 μg OVA plus A) except for mice 1 (see below). l(OH)3) in 0.3 ml of phosphate-buffered saline ("PBS") on day 0. All mice were given 100 mg of ... The mice were fed with egg white solution (filtered 20% (w / v) EWS) at 100°C.
[0039] IMIG (Gamunex® 25 μg: Grifols) and anti-varicella Ig (25 μg: Grifols) was administered intravenously weekly from days 7 to 35. .
[0040] The following groups were used: Group 1: OVA - / EWS + Group 2: OVA + / EWS + Group 3: Group 2 + IMIG (OVA) + / EWS + +IMIG) Group 4: Group 2 + anti-varicella Ig (OVA) + / EWS + +Anti-Varicell aIg) Group 5: Group 2 + IMIG + anti-varicella Ig (OVA) + / EWS + +IMIG+Ant i-VaricellaIg)
[0041] All mice were sacrificed on day 49 of the study. At the time of sacrifice, OVs obtained by cardiac puncture were Serum IgE against A was measured using a mouse model of OVA coated with HRP-antimacroglobulin (HRP) at 100 ng / well. The antibody was measured by ELISA using plates developed with mouse IgE and appropriate substrates. Ta.
[0042] Plus 5x10 from individual animals 6 splenocytes were in vitro treated with OVA at 1 μg / ml The cells were exposed to 2 ml of the culture medium for 72 hours, and IL-2 / IL-4 was measured using a commercially available ELISA kit ( Measurements were performed in culture supernatants using eBIOSciences.
[0043] result Figure 2A shows that OVA did not attenuate IL-2 production when it stimulated individual mouse splenocytes. On the other hand, Figure 2B shows a clear attenuation of IL-4 production. The present study carried out in Example 1 using a combined infusion of IMIG and anti-tetanus Ig (See Figures 1C and 1D).
[0044] [Example 3] Polyclonal human IMIG and polyclonal IMIG were tested in peanut butter-sensitized beagle dogs. Clonal human anti-tetanus Ig, or polyclonal canine Ig and canine anti-rabies Ig were used. Allergy Experimental Protocol In a modification of the protocol in Examples 1 and 2, the inventors applied topically The prevalence of allergic sensitization induced by peanut butter spread on food is high (>80%). Previous literature reports have shown that it reduces allergic sensitization in large animals (beagles). We considered whether it would be possible to do so.
[0045] The animals received a first exposure of 1 week prior to treatment and then weekly exposure to peanut butter. The next five exposures to peanut butter were given to the combined dogs. g (IMIG and pooled canine anti-rabies Ig) or combined human Ig (IMIG and pooled human anti-rabies Ig) After 5 weeks of treatment, all animals received the same I All dogs received three more treatments with the 200 mg / kg mixture every 14 days. The subjects were orally challenged with peanut butter, and serum IgG, serum IgE, and peanut butter inducers were measured. The production of IL-2 / IL-4 by the cells was measured.
[0046] Received canine intramuscular immunoglobulin (Innovative Research, USA). The dog was given an intramuscular injection of 1 mg / kg of PBS in the gluteal muscle. Pooled canine anti-rabies immune Ig (by re-immunizing pooled dogs with rabies vaccine) 1 mg / kg of 100 mg ... Intramuscular injection was administered.
[0047] Receive human intramuscular immunoglobulin (Gamunex®, Grifols) A dose of 1 mg / kg was administered intramuscularly to the gluteal muscle of dogs using 0.5 ml of PBS as a vehicle. Dogs receiving tung Ig (HyperTET, Grifols) were injected with PBS into the gluteal muscle opposite the vena cava. 0.5 ml of the vehicle was used for intramuscular injection at 1 mg / kg.
[0048] result Figures 3A and 3B show the total serum IgG levels at the start (t0) and end (t1) of the study. Figures 3C and 3D show the results of the comparison with the total serum IgG level at time point (t1). The total serum IgE levels at the start (t0) and end (t1) of the study were The IgG level did not change significantly, but the IgE level The reduction in serum IgG levels was observed in dogs treated with canine IMIG and canine anti-rabies Ig compared with dogs treated with human IMIG and This was observed both after treatment with tetanus antibodies and with human anti-tetanus Ig.
[0049] Figures 3E and 3F show concomitant leukemia in canine peripheral blood lymphocytes (PBLs) before treatment (t0). IL-2 production by Navarin A (ConA) and the post-treatment (t1) change in canine peripheral blood lymphocytes ( Comparison of IL-2 production by concanavalin A (ConA) in PBL show.
[0050] Figures 3G and 3H show ConA-induced IL-4 production in canine PBL before treatment (t0). Comparison of ConA-induced IL-4 production in canine PBLs between fresh and post-treatment (t1) was performed. Shows.
[0051] Figure 3I shows IL-2 / IL-4 induction by ConA in canine PBL before and after Ig treatment. Even for this polyclonal response, the IL-2 / IL-4 ratio was significantly higher in dogs than in dogs with IgE. Note that the mean mean age was higher in dogs after treatment with human IgG or human IgG (*, p<0.05). I want to be done that.
[0052] Figure 3J shows the results after treatment with canine IMIG and canine anti-rabies Ig, and human IMIG and human Peanut butter stimulates canine PBL after treatment with anti-tetanus Ig. Figure 3K shows the IL-2:IL-4 ratio after treatment. Consistent with other experiments, IL-4 production was attenuated by Ig treatment, whereas IL-2 production was Furthermore, the IL-2:IL-4 ratio was higher after treatment (*, p<0.0). 5).
[0053] [Example 4] Dose-Response Study - Polyclonal Human IMIG vs Polyclonal Human in Pre-immunized Mice Anti-tetanus Ig We compared polyclonal human IMIG and polyclonal human IMIG in pre-immunized mice. A dose-response study was also performed using anti-tetanus Ig.
[0054] In the dose-response study, all groups had five BALB / c mice each. All mice were injected with OVA (10 μg O) on days 0 and 14. VA plus Al(OH3)) and boosted on day 56. All mice received From the 14th day, EWS (filtered 20% (w / v) egg white solution) was administered in a drinking container. Gave it.
[0055] Mice were injected with immunoglobulin on days 56, 63, 70, 77, and 84. Injection treatment was started.
[0056] The following groups were used: Group 1 (control): OVA immunization and EWS (No IMIG or Anti-Tet) Group 2: Group 1 + IMIG (250 μg / mouse) + anti-tetanus Ig (10 μg / mouse) (IMIG 250 :Tet 10 ) Group 3: Group 1 + IMIG (250 μg / mouse) + anti-tetanus Ig (50 μg / mouse) (IMIG 250 :Tet 50 ) Group 4: Group 1 + IMIG (250 μg / mouse) + anti-tetanus Ig (250 μg / Mouse) (IMIG 250 :Tet 250 ) Group 5: Group 1 + IMIG (50 μg / mouse) + anti-tetanus Ig (10 μg / mouse) IMIG 50 :Tet 10 ) Group 6: Group 1 + IMIG (50 μg / mouse) + anti-tetanus Ig (50 μg / mouse) IMIG 50 :Tet 50 ) Group 7: Group 1 + IMIG (50 μg / mouse) + anti-tetanus Ig (250 μg / mouse) (IMIG 50 :Tet 250 ) Group 8: Group 1 + IMIG (10 μg / mouse) + anti-tetanus Ig (10 μg / mouse) IMIG 10 :Tet 10 ) Group 9: Group 1 + IMIG (10 μg / mouse) + anti-tetanus Ig (50 μg / mouse) IMIG 10 :Tet 50 ) Group 10: Group 1 + IMIG (10 μg / mouse) + anti-tetanus Ig (250 μg / Mouse) (IMIG 10 :Tet 250 ) Group 11: Group 1 + IMIG (50 μg / mouse) + anti-tetanus Ig (50 μg / mouse) + Coenzyme Q10 ip (100 μg / mouse) from day 56 to day 90 Every 2 days (IMIG 50 :Tet 50 :Q10) Group 12: Group 1 + IMIG (250 μg / mouse) (IMIG 250 ) Group 13: Group 1 + anti-tetanus Ig (50 μg / mouse) (Anti-Tet 50 )
[0057] The final boost with OVA was on day 90 and the mice were sacrificed on day 97.
[0058] Serum OVA-specific IgG / IgE was measured by ELISA. 6 Splenocytes were exposed to 2 ml of OVA 1 μg / ml culture medium in vitro for 72 hours. IL-2 / IL-4 were cultured using a commercially available ELISA kit (BioLegend). Measured in the supernatant.
[0059] result Figures 4A and 4B show that optimal suppression of IgE responses was achieved with IMIG at 250 μg / mouse and 5 μg / mouse. 0 μg / mouse provides a wide range of anti-tetanus effects (10-250 μg / mouse) At lower doses of IMIG (10 μg / mouse), Coenzyme Q10 was administered to the animals as an antioxidant every two days (1 00 μg / mouse), a relatively small IMIG dose (50) and anti-tetanus dose At a dose of 50, there was some synergistic effect in suppression. No attenuation of the IgG response occurred. (Figure 4B).
[0060] 4C, 4D, and 4E show the results of the experiments using IL-4 and IL-2 production as measurements. This confirms the data in Figures 4A and 4B. When administered at 50 μg / mouse, it has a wide range of anti-tetanus effects (10-250 μg / mouse). ), suppression of IL-4 production was observed, but not of IL-2 production. The lower the IMIG dose (10 μg / mouse), the less suppressive the effect. The animals were given coenzyme Q10 (100 μg / mouse) every two days as an antioxidant. When administered, it was suppressed with relatively low doses of IMIG (50) and anti-tetanus (50). This data was obtained by comparing the IL-2:IL-4 ratio as shown in Figure 4E. This is further emphasized by comparison.
