Published: January 2019

Oncostain M, a member of the IL-6 family of cytokines, is produced by immune cells in response to infections and tissue injury. OSM has a broad, often context-dependent effect on various cellular processes including differentiation, hematopoiesis, cell proliferation, and cell survival. OSM signaling is initiated by binding to type I (LIFRβ/gp130) or type II (OSMRβ/gp130) receptor complexes and involves activation of Janus kinase/signal transducer and activator of transcription, mitogen-activated protein kinase, and phosphatidylinositol-3-kinase. High levels of OSM have been detected in many chronic inflammatory conditions characterized by fibrosis, giving a rationale to target OSM for the treatment of these diseases. Here we discuss the current knowledge on the role of OSM in various stages of the fibrotic process including inflammation, vascular dysfunction, and activation of fibroblasts.

Antigen presentation plays a critical role in the pathogenesis of immune-mediated disorders. This study aimed to investigate the effects of IFN-γ and a cytokine mix (5MIX: IL-1α, IL-17A, IL-22, OsM, and TNF-α) on the antigen-presenting capabilities of keratinocytes, with a specific focus on immune-mediated dermatological conditions such as psoriasis (Ps). To achieve this, keratinocytes were treated with IFN-γ and 5MIX, and their impact on the expression of key antigen-presentation molecules, HLA-DRα and CD74, was assessed.

Retinal diseases, which can lead to significant vision loss, are complex conditions involving various cellular and molecular mechanisms. The interleukin-6 (IL-6) family, particularly Oncostatin M (OSM), has garnered attention for their roles in retinal inflammation, angiogenesis, and neuroprotection. This comprehensive review explores the dual nature of OSM and other IL-6 family members in retinal pathophysiology, highlighting their contribution to both degenerative and regenerative processes.

Alpha-synuclein (αS) aggregation is a widely regarded hallmark of Parkinson's disease (PD) and can be detected through synuclein amplification assays (SAA). This study investigated the association between cerebrospinal fluid (CSF) radiological measures in 41 PD patients (14 iPD, 14 GBA1-PD, 13 LRRK2-PD) and 14 age-and-sex-matched healthy controls. Quantitative measures including striatal binding ratios (SBR), whole-brain and deep gray matter volumes, neuromelanin-MRI (NM-MRI), functional connectivity (FC), and white matter (WM) diffusion-tensor imaging (DTI) were calculated.

Introduction: It remains unclear why up to 30% of ulcerative colitis patients (UC) do not respond to tumor necrosis factor inhibitors (TNFi). Validated biomarkers for (non-)response ((N)R) are lacking. Most studies investigating underlying mechanisms do not differentiate between pharmacokinetic and inflammatory mechanisms.

Introduction: Glucocorticoids (GCs) are widely used as a treatment for rheumatoid arthritis (RA), leading to high cumulative doses in long-term treated patients. The impact of a high cumulative GC dose on the systemic inflammatory response in RA remains poorly understood.

Methods: We investigated long-treated patients with RA (n = 72, median disease duration 14 years) through blood counts and the serum levels of 92 inflammation-related proteins, and disease activity was assessed using the Simple Disease Activity Index (SDAI).
