Deletion of the C6orf120 gene with unknown function ameliorates autoimmune hepatitis induced by concanavalin A.

Abstract:

:The present study was conducted to characterize the C6orf120 gene, by using C6orf120 gene-deleted rats (C6orf120-/-), to determine its role in the development and severity of autoimmune hepatitis induced by concanavalin A (Con A), as well as the underlying mechanisms. We found that following Con A injection, C6orf120-/- rats were less susceptible to developing autoimmune hepatitis with low levels of alanine aminotransferase (ALT) and aspartate aminotransferase (AST) post challenge. Additionally, C6orf120 deficiency increased the frequency of cluster of differentiation (CD)4+ CD25+ Forkhead box P3+ regulatory T cells (Tregs) among intrahepatic lymphocytes, splenocytes, peripheral blood mononuclear cells, and CD4+ T in vitro. Moreover, C6orf120 deficiency downregulated interleukin (IL)-1β, IL-6, tumor necrosis factor alpha-α, interferon-γ and IL-17a secretion in the plasma and liver tissues. Our results indicated that the C6orf120 gene-deleted rats were less susceptible to Con A-induced autoimmune hepatitis, which may be partly related to the increased frequency of Tregs and inhibited secretion of inflammatory cytokines.
