Intervention of Inflammatory Monocyte Activity Limits Dermal Fibrosis
2019
Monocytes and monocyte-derived cells are important players in the initiation, progression, and resolution of inflammatory skin reactions. As inflammation is a prerequisite for fibrosis development, we focused on the role of monocytes in cutaneous fibrosis, the clinical hallmark of patients suffering from systemic sclerosis. Investigating the function of monocytes in reactive oxygen species–induced dermal fibrosis, we observed that early monocyte depletion partially reduced disease severity. Low numbers of inflammatory Ly6Chigh monocytes, as well as inhibition of CCR2 and CCL2 in wild type animals by a specific L-RNA aptamer, mitigated disease parameters, indicating a pivotal role for CCR2+ …
The cyclopentenone-type prostaglandin 15-deoxy-delta12,14-prostaglandin J2 inhibits CD95 ligand gene expression in T lymphocytes: interference with p…
2003
Abstract 15-Deoxy-Δ12,14-PGJ2 (15d-PGJ2) is a cyclopentenone-type PG endowed with anti-inflammatory properties and produced by different cells, including those of the immune system. 15d-PGJ2 is a natural ligand of the peroxisome proliferator-activated receptor (PPAR)-γ nuclear receptor, but relevant PPARγ-independent actions mediated by this prostanoid have been described. Fas (APO-1/CD95) and its ligand (Fas-L) are cell surface proteins whose interaction activates apoptosis of Fas-expressing targets. In T cells, the Fas-Fas-L system regulates activation-induced cell death and has been implicated in diseases in which lymphocyte homeostasis is compromised. Moreover, several studies have desc…
Class IIa HDACs repressive activities on MEF2-depedent transcription are associated with poor prognosis of ER⁺ breast tumors.
2013
MEF2s transcription factors and class IIa HDACs compose a fundamental axis for several differentiation pathways. Functional relationships between this axis and cancer are largely unexplored. We have found that class IIa HDACs are heterogeneously expressed and display redundant activities in breast cancer cells. Applying gene set enrichment analysis to compare the expression profile of a list of putative MEF2 target genes, we have discovered a correlation between the down-regulation of the MEF2 signature and the aggressiveness of ER(+) breast tumors. Kaplan-Meier analysis in ER(+) breast tumors evidenced an association between increased class IIa HDACs expression and reduced survival. The im…
