Interleukin-32 in systemic sclerosis, a potential new biomarker for pulmonary arterial hypertension
2020
Abstract Background Pulmonary arterial hypertension (PAH) is a severe complication of systemic sclerosis (SSc), associated with a progressive elevation in pulmonary vascular resistance and subsequent right heart failure and death. Due to unspecific symptoms, the diagnosis of PAH is often delayed. On this basis, it is of great value to improve current diagnostic methods and develop new strategies for evaluating patients with suspected PAH. Interleukin-32 (IL-32) is a proinflammatory cytokine expressed in damaged vascular cells, and the present study aimed to assess if this cytokine could be a new biomarker of PAH during SSc. Methods The IL-32 expression was evaluated in the sera and skin sam…
Interleukin 27 induces differentiation of neural C6-precursor cells into astrocytes.
2007
Interleukin 6 (IL6)-type cytokines are major regulators of inflammation and thereby contribute to the neuropathology and pathophysiology associated with inflammation of the central nervous system (CNS). Furthermore, astrocyte development which is a key process in the development of the CNS is also controlled by cytokines of the IL6-family. Interleukin 27 (IL27) is a recently identified member of this family and has been implicated in the inhibition of TH17 T-cell-responses. Here we show that IL27 and the HHV8 encoded viral IL6 (vIL6) induce C6 glioma cells to differentiate into an astrocyte-like state. Cytokine stimulation led to STAT-factor phosphorylation and consequently to protein expre…
Increased expression of interleukin-32 in the inflamed ileum of ankylosing spondylitis patients
2012
Objective. To study the mRNA expression and protein tissue distribution of IL-32 in ileal biopsy specimens from patients with AS. Methods. Quantitative gene expression analysis, by real-time PCR, of IL-32, IL-1b, IL-10, TNF-a and IFN-g was performed on ileal biopsies of 15 AS and 15 Crohn’s disease (CD) patients and 10 healthy subjects (HSs). IL-32 tissue distribution was evaluated by immunohistochemistry. The effect of IL-32 on the production of IL-10 by intestinal epithelial cell lines was also evaluated. Results. In the ileal specimens of patients with AS and intestinal chronic inflammation, significant up-regulation of IL-32 at both the mRNA and protein levels was found as compared with…
OP0299 Serum and glomerular expression of IL32 in lupus nephritis
2017
Background Lupus nephritis (LN) is one of the most severe features of systemic lupus erythematosus (SLE). Several cytokines and chemokines are secreted locally in case of glomerular inflammation. Interleukin 32 (IL32) is a newly described cytokine that exhibits several properties typical of proinflammatory cytokines. Ex vivo and in vitro studies supported the role of Toll like receptors (TLRs) in LN pathogenesis and recent investigations demonstrated that Poly I:C, a ligand for (TLR) 3, strongly induced IL32 production from several cell populations. Objectives To investigate serum and urinary levels of IL32 in a cohort of LN patients compared to SLE patients without renal involvement and he…
