Abstract
Hemophilia A is caused by a deficiency in coagulation factor VIII (FVIII) and predisposes to spontaneous bleeding that can be life-threatening or lead to chronic disabilities. It is well suited for gene therapy because a moderate increase in plasma FVIII concentration has therapeutic effects. Improved retroviral vectors expressing high levels of human FVIII were pseudotyped with the vesicular stomatitis virus G glycoprotein, were concentrated to high-titers (10(9)-10(10) colony-forming units/ml), and were injected intravenously into newborn, FVIII-deficient mice. High-levels (>/=200 milliunits/ml) of functional human FVIII production could be detected in 6 of the 13 animals, 4 of which expressed physiologic or higher levels (500-12,500 milliunits/ml). Five of the six expressers produced FVIII and survived an otherwise lethal tail-clipping, demonstrating phenotypic correction of the bleeding disorder. FVIII expression was sustained for >14 months. Gene transfer occurred into liver, spleen, and lungs with predominant FVIII mRNA expression in the liver. Six of the seven animals with transient or no detectable human FVIII developed FVIII inhibitors (7-350 Bethesda units/ml). These findings indicate that a genetic disease can be corrected by in vivo gene therapy using retroviral vectors.

Abstract
To investigate the consequences of CD40 engagement on the neonatal induction of transplantation tolerance, BALB/c mice were injected at birth with (A/J x BALB/c) F1 spleen cells together with activating anti-CD40 mAb and grafted 4 wk later with A/J skin. Whereas A/J allografts were accepted in mice neonatally injected with F1 cells and control Ab, they were acutely rejected in mice injected with F1 cells and anti-CD40 mAb. Neonatal administration of anti-CD40 mAb resulted in enhanced anti-A/J CTL activity, increased IFN-gamma, and decreased IL-4 production by donor-specific T cells in vitro. Experiments using anti-cytokine mAb and IFN-gamma-deficient mice demonstrated that CD40 ligation prevents neonatal allotolerance through an IFN-gamma- and IL-12-dependent pathway. Finally, we found that newborn T cells express less CD40L than adult T cells upon TCR engagement. Taken together these data indicate that insufficiency of CD40/CD40L interactions contribute to neonatal transplantation tolerance.

Abstract
We investigated the effect of IL-12 on the induction of transplantation tolerance by neonatal injection of allogenic cells. We first observed that injection of newborn BALB/c mice with IL-12 and (A/J x BALB/c)F1 spleen cells prevented the Th2 alloimmune response induced by neonatal inoculation of F1 cells alone and allowed the differentiation of T cells secreting high amounts of IL-2 and IFN-gamma in mixed lymphocyte cultures with donor-type stimulators. Furthermore, IL-12 administration resulted in the emergence of anti-donor cytotoxic T lymphocyte responses although at lower levels than in control uninjected mice. In parallel, we found that mice injected at birth with IL-12 and F1 cells did not develop chimerism and were able to reject a donor-type skin graft as efficiently as control mice. We conclude that IL-12 inhibits the Th2 polarization of the newborn response to alloantigens and prevents thereby the establishment of transplantation tolerance.

Abstract
Neonatal injection of semiallogeneic cells is known to promote differentiation of donor-specific CD4+ T cells into TH2-like cells in the peripheral lymphoid organs. We reasoned that the propensity of neonatal T cells to synthesize high levels of IL-4 might be involved in this polarization of the alloreactive response and thereby in the development of neonatal transplantation tolerance. First, analysis of cytokine gene expression in lymph nodes after neonatal injection of 10(7) (A/J x BALB/c)F1 cells in BALB/c mice indicated that IL-4 but not IL-2 is rapidly produced by CD4+ cells after allogeneic challenge in vivo. To determine whether the early production of IL-4 was involved in the establishment of allotolerance, BALB/c mice neonatally injected with (A/J x BALB/c)F1 spleen cells received on days 1 and 3 after birth 1 mg of anti-IL-4 mAb (11B11) or the same amount of control mAb. When grafted with A/J skin at 4 weeks, 88% of mice treated with control mAb retained their graft for more than 50 days, whereas rejection occurred within 30 days in 93% of mice treated with anti-IL-4 mAb. Analysis of T cell functions after in vitro restimulation with A/J spleen cells indicated that early IL-4 neutralization did not prevent donor-specific CTL unresponsiveness but allowed the emergence of alloreactive T cells secreting increased levels of IL-2 and IFN-gamma. We conclude that early production of IL-4 is critical for the establishment of neonatal transplantation tolerance in this strain combination, which has disparities across the entire H-2 region.

Abstract
Abstract
BALB/c mice injected at birth with 10(8) (A/J X BALB/c)F1 hybrid spleen cells develop an autoimmune host-vs-graft (HVG) disease as a result of activation of donor B cells by host CD4+ cells. The antidonor CD4+ cells seem to be Th2-like cells, inasmuch as they are profoundly deficient in IL-2 and IFN-gamma production, but secrete high levels of IL-4 and IL-10. As IFN-gamma is known to inhibit the development of TH2 cells, we attempted to modulate HVG disease by injecting rIFN-gamma. First, we found that 10 micrograms of rIFN-gamma given on days 1 and 3 after birth reduced the serum hyper-IgE of HVG mice by 90% and the serum hyper-IgG1, by 70%. In addition, rIFN-gamma administration significantly decreased the anti-DNA IgG1 titers and prevented the occurrence of anti-glomerular basement membrane and anti-laminin IgG1 Abs as well as the formation of immune deposits in renal glomeruli. These effects were not caused by the abrogation of chimerism, as indicated by the persistence of donor-type B cells in lymph nodes and of Igs bearing donor allotype in serum. MLC experiments indicated that the major effect of early rIFN-gamma administration was to restore the production of IL-2 and IFN-gamma by donor-specific T cells while these cells still secreted significant amounts of IL-4 and IL-10. Unresponsiveness of antidonor cytolytic T cells was not influenced by rIFN-gamma. We conclude that rIFN-gamma prevents the TH2-type response induced by the neonatal injection of semiallogeneic spleen cells and the associated pathology.
