TL;DR: It is shown that PPAR-γ is markedly upregulated in activated macrophages and inhibits the expression of the inducible nitric oxide synthase, gelatinase B and scavenger receptor A genes in response to 15d-PGJ2 and synthetic PPar-γ ligands, suggesting that PPARS and locally produced prostaglandin D2 metabolites are involved in the regulation of inflammatory responses.

TL;DR: Findings reveal a physiological role of 12/15-lipoxygenase in the generation of endogenous ligands for PPAR-γ, and suggest a paradigm for the regulation of nuclear receptor function by cytokines.

TL;DR: It is suggested that MCT cells provide all the necessary biological parameters for interfacing both as the target of a nephritogenic immune response, and as a potential source for new extracellular matrix which develops as a fibrogenic response to interstitial nephritis.

TL;DR: These findings support the roles of PPAR ligands in modulating inflammatory responses involving lymphocytes but also establish potent effects of the fibrate class of PParα ligands on IL-4 expression that are receptor independent.
