Project description:Monocytes and their lineage descendants serve as a central defense system against infection and injury but if uncontrolled can also promote an excessive pathological inflammatory response. Therefore a current research goal is to understand how the organism controls the number and function of monocytes and how these variables can be tailored in therapy. Considering the evidence that monocytes are heterogeneous and exist in at least two subsets committed to divergent functions, we investigated whether distinct factors regulate the balance between monocyte subset responses in vivo. We identified a microRNA (miRNA), miR-146a, which is differentially regulated both in mouse (Ly-6Chi and Ly-6Clo) and human (CD14hi and CD14lo CD16+) monocyte subsets. The single miRNA was found to significantly control the amplitude of the Ly-6Chi monocyte response during inflammatory challenge whereas it did not affect Ly-6Clo cells. miR-146a–mediated regulation was cell-intrinsic and depended on Relb, a member of the non-canonical NF-κB/Rel family, which is identified here as a novel miR-146a target. These observations provide novel mechanistic insights into the molecular events that regulate monocyte functional heterogeneity and identify therapeutic targets that can influence the quality and quantity of monocyte responses.

Each sample was generated by fluorecsence activated cell sorting from the pooled spleens of 10 mice.

Project description:To gain insight into the mechanisms underlying miR-146a-mediated modulation of Ly6Chigh monocyte function, we compared the expression profiles of Ly6Chigh and Ly6Clow monocytes in miR-146a+/+ (WT) versus miR-146a-/- (KO) conditions.

Project description:MiR-146a is an important regulator of innate inflammatory responses and is also implicated in cell death and survival. Here, we identified microglia as the main cellular source of miR-146a among mouse CNS resident cells. We further characterized the phenotype of miR-146a KO microglia cells during in vivo demyelination induced by cuprizone (CPZ) and found reduced number of CD11c+ microglia in the KO compared to WT mice. Microglia were also isolated from the brain, and the proteome was analyzed by liquid chromatography mass spectrometry.
