Here, we tested whether aGvHD therapy could be improved by delivering GCs with the help of inorganic–organic hybrid nanoparticles (IOH‐NPs) that preferentially target myeloid cells. IOH‐NPs containing the GC betamethasone (BMP‐NPs) efficiently reduced morbidity, mortality, and tissue damage in a totally MHC mismatched mouse model of aGvHD. Therapeutic activity was lost in mice lacking the GC receptor (GR) in myeloid cells, confirming the cell type specificity of our approach. BMP‐NPs had no relevant systemic activity but suppressed cytokine and chemokine gene expression locally in the small intestine, which presumably explains their mode of action. Most importantly, BMP‐NPs delayed the development of an adoptively transferred B cell lymphoma better than the free drug, although the overall incidence was unaffected. Our findings thus suggest that employing IOH‐NPs could diminish the risk of relapse associated with GC therapy of aGvHD patients while still allowing to efficiently ameliorate the disease."],["dc.description.abstract","Clinical symptoms and histological hallmarks of acute graft‐versus‐host disease in mice are ameliorated by glucocorticoids when specifically delivered to macrophages with the help of nanoparticles.

Endogenous glucocorticoids (GC) released from the adrenal gland are crucial in regulating such inflammatory diseases. Here we demonstrate that genetically engineered mice, that are largely unresponsive to GC, suffer from aggravated clinical symptoms and increased mortality after HSCT, effects that could be tempered by neutralization of IL-6. Interestingly, selective ablation of the GC receptor (GR) in recipient myeloid cells resulted in fulminant disease as well. While histopathological analysis of the jejunum failed to reveal any differences between sick mice of both genotypes, systemic IL-6 and TNFα secretion was strongly increased in transplanted mice lacking the GR in myeloid cells briefly before the majority of them succumbed to the disease.

Currently, the standard first-line treatment of IBD consists of systemic glucocorticoid (GC) application, even though therapy can be complicated by unresponsiveness or adverse effects. In view of the importance of macrophages and neutrophils for the pathogenesis of IBD we set out to define the relevance of these cell types as targets of GC using the mouse model of DSS-induced colitis. We found that the disease did not resolve in GRlysM mice lacking the GC receptor (GR) in myeloid cells after removal of the chemical insult. While clinical symptoms and tissue damage in the colon ameliorated again in GRflox mice, the disease further aggravated in GRlysM littermates. The observed difference coincided with an increased abundance of macrophages in inflammatory infiltrates in the colon of mutant mice whereas neutrophil and T cell numbers were similar. Concomitantly, systemic IL-6 secretion and mRNA levels of pro-inflammatory cytokines in the colon were elevated in GRlysM mice and gene expression of scavenger receptors and IL-10 was diminished. Taken together, our results reveal an important role of myeloid cells as targets of GC in DSS-induced colitis and probably in IBD in humans as well."],["dc.identifier.doi","10.1371/journal.pone.0190846"],["dc.identifier.pmid","29324769"],["dc.identifier.purl","https://resolver.sub.uni-goettingen.de/purl?gs-1/15039"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/59164"],["dc.language.iso","en"],["dc.notes.intern","Merged from goescholar"],["dc.relation.issn","1932-6203"],["dc.rights","CC BY 4.0"],["dc.rights.uri","https://creativecommons.org/licenses/by/4.0"],["dc.subject.ddc","610"],["dc.subject.mesh","Animals"],["dc.subject.mesh","Colitis"],["dc.subject.mesh","Colon"],["dc.subject.mesh","Dextran Sulfate"],["dc.subject.mesh","Disease Models, Animal"],["dc.subject.mesh","Interleukin-10"],["dc.subject.mesh","Interleukin-6"],["dc.subject.mesh","Intestinal Mucosa"],["dc.subject.mesh","Mice, Inbred C57BL"],["dc.subject.mesh","Mice, Transgenic"],["dc.subject.mesh","Myeloid Cells"],["dc.subject.mesh","RNA, Messenger"],["dc.subject.mesh","Receptors, Glucocorticoid"],["dc.title","Impaired resolution of DSS-induced colitis in mice lacking the glucocorticoid receptor in myeloid cells"],["dc.type","journal_article"],["dc.type.internalPublication","yes"],["dc.type.version","published_version"],["dspace.entity.type","Publication"]]
