Genome-wide RNA expression analysis of mouse spleens in parent-into-F1 lupus immune response

ABSTRACT: Analysis of whole spleen tissue expression signature in divergent responses from two parent-into-F1 lupus mouse model systems. The hypothesis is that strain differences of CD4 T cells exhibit difference lupus-inducing proclivity. Total RNA obtained from recipient mouse spleen at day 14 post-engraftment were profiled by Illumina BeadArray expression analysis

Using the parent-into-F1 model of induced lupus and (C57BL/6 × DBA2) F1 mice as hosts, we compared the inherent lupus-inducing properties of the two parental strain CD4 T cells. To control for donor CD4 recognition of alloantigen, we used H-2(d) identical DBA/2 and B10.D2 donor T cells. We demonstrate that these two normal, nonlupus-prone parental strains exhibit two different T cell activation pathways in vivo. B10.D2 CD4 T cells induce a strong Th1/CMI pathway that is characterized by IL-2/IFN ...[more]

Project description:A major challenge in bone allogeneic marrow (BM) transplantation is overcoming engraftment resistance to avoid the clinical problem of graft rejection. Identifying genes and pathways that regulate BM engraftment may reveal molecular targets for overcoming these engraftment barriers. Previously, we developed a mouse model of BM transplantation that utilizes recipient conditioning with non-myeloablative total body irradiation followed by transplantation of allogeneic BM cells. We defined TBI doses that lead to graft rejection, that are permissive for engraftment, and mouse strain variation with regards to the permissive TBI dose. We now report gene expression analysis, using the Agilent Mouse 8x60K v3 expression arrays, in spleen of mice conditioned with TBI doses for evaluation in correlation to the expected engraftment phenotype. The spleens of mice given TBI demonstrated extensive differential gene expression, compared with un-irradiated controls, at both multiple testing-corrected P < .05 and fold change greater than or equal to 2 levels. Functional analysis revealed significant enrichment for up-regulation of canonical pathways involved in inflammation, even when treated with TBI doses not permissive for engraftment. Consistent with this the most significantly associated upstream regulators included lipopolysaccharide, tumor necrosis factor, and a toll-like receptor. Unique to engrafting mice, however, were enrichment for a down-regulated canonical pathway related to B-cell development. Results from this analysis have identified canonical pathways and upstream regulators of BM engraftment in mice and may lead to new approaches to overcome the problem of graft rejection complicating clinical BM transplantation. Each individual sample was pooled from 3 mice and performed in triplicate for each experimental group (TBI 300 cGy, 400 cGy, or 500 cGy) and for each strain mice (BALB.K or B10.BR) for statistical analysis. Additional arrays were perfromed for TBI 800 cGy (BALB.K) and TBI 900 cGy (B10.BR) for anlaysis of gene expressive after myeloablative condition.
