Purpose Of Review: Cytokines are major drivers of autoimmunity, and biologic agents targeting cytokines have revolutionized the treatment of immune-mediated diseases. Janus kinase/signal transducer and activator of transcription (JAK-STAT) pathway represents a group of several intracellular molecules with a key role in signal pathways activated by growth factors and cytokines. These kinase proteins are associated with the signaling process of multiple key cytokines, which regulates various T-cell subpopulations and their effector cytokines. Development of novel drugs to inhibit this kinase cascade is an emerging field in clinical immunology. Thus, it is essential to have insights about the regulatory role of the JAK-STAT cytokine signaling in relation to autoimmune diseases and its applications in spondyloarthritis.
Recent Findings: JAK-STAT kinase signaling proteins have been extensively studied in rheumatoid arthritis. Initial observations suggest that JAK-STAT kinase signaling cascade regulates activation and proliferation of the IL17 effector memory T cells and thus has a potential role in the pathogenesis of psoriasis, psoriatic arthritis and ankylosing spondylitis.
Summary: Here, we provide an overview of the clinical rheumatologists about the significance of JAK-STAT signaling system in rheumatic diseases and introduce the potential application of JAK and STAT inhibitors in spondyloarthritis.

Lumbar spinal stenosis (LSS) is one of the most common spinal disorders in elderly people and is often accompanied by neuropathic pain. Although our previous studies have demonstrated that infiltrating macrophage contribute to chronic neuropathic pain in LSS rat model, the molecular mechanisms underlying macrophage activation and infiltration have not been fully elucidated. In this study, we examined the critical role of platelet-derived growth factor receptor (PDGFR) signaling pathway in neuropathic pain associated with macrophage infiltration and activation in LSS rats.

Pseudoautosomal regions (PARs), located at the ends of sex chromosomes, harbor genes that may play a role in tumor pathology by regulating cell proliferation and the immune microenvironment. Gastric cancer (GC) is a prevalent and molecularly heterogeneous malignancy of the digestive system. However, studies on the role of PARs-related genes in GC are limited.

Curcumin, a natural polyphenolic compound derived from , has shown great potential in the prevention and treatment of chronic inflammatory diseases due to its significant antioxidant and anti-inflammatory properties. This article aims to systematically review the anti-inflammatory molecular mechanism, clinical application prospects and challenges of curcumin. By searching the databases of Web of Science, PubMed, Google Scholar and CNKI, and integrating the latest research progress, it was found that curcumin exerted its core anti-inflammatory effects mainly by inhibiting the activation of nuclear factor-κB (NF-κB) signaling pathway, regulating the mitogen-activated protein kinase extracellular signal-regulated kinase (ERK) phosphorylation cascade, and regulating the Janus kinase/signal transducer and activator of transcription (JAK/STAT) pathway.

Background: Hepatitis D virus (HDV) infection is the most severe form of human viral hepatitis. A poor virus-specific CD8T cell response may result in persistent HDV infection. We investigated anti-viral effect and mechanisms of ubiquitinated small hepatitis D antigen (Ub-S-HDAg) in HBV/HDV superinfected liver organoids.

Background: Myelofibrosis (MF) can be primary (PMF) or secondary (SMF), with PMF driven by Janus kinases-signal transducer and activator of transcription proteins (JAK-STAT) pathway activation due to Janus kinase 2 (), the thrombopoietin receptor gene (myeloproliferative leukemia virus oncogene ()), or calreticulin () mutations. Nearly 50% of PMF patients experience anemia (hemoglobin (Hb) < 10 g/dL), often worsened by JAK inhibitors like ruxolitinib and fedratinib. Momelotinib, an oral ACVR1, JAK1, and JAK2 inhibitor, improves anemia, symptoms, and splenomegaly, likely through hepcidin regulation.
