The oral Janus kinase 1 (JAK1) inhibitor abrocitinib, which reduces interleukin-4 and interleukin-13 signaling, is being investigated for the treatment of atopic dermatitis. Data from trials comparing JAK1 inhibitors with monoclonal antibodies, such as dupilumab, that block receptors are limited.
Two placebo-controlled trials reported in this issue of the Journal show the efficacy of an oral Janus kinase (JAK) inhibitor, tofacitinib, in the treatment of rheumatoid arthritis.1,2 If this agent is approved by the Food and Drug Administration (FDA) for use in patients with rheumatoid arthritis, clinicians will confront several complex questions. What is the rationale for targeting this fami...
The role of Janus-activated kinase (JAK) signaling in cell cycle transit and maintenance of genomic stability was determined in HL-60 myeloblastic leukemia cells. Inhibition of JAKs, all JAKs (JAK1, JAK2, JAK3, and tyrosine kinase 2), JAK2, or JAK3, caused a significant reduction in cell growth with a major G2-M arrest evident 24 hours after treatment. Targeting all JAKs also caused endoredupli...
Tyrosine kinase signaling is tightly controlled by negative feedback inhibitors including suppressors of cytokine signaling (SOCS). SOCS assemble as SH2 domain substrate recognition modules in ElonginB/C-cullin ubiquitin ligases. In accordance, SOCS4 reduces STAT3 signaling from EGFR through increased receptor degradation. Variable C-termini in SOCS4-SOCS7 exclude these family members from a SO...
Leptin is secreted by adipose tissue and regulates energy homeostasis, glucose and lipid metabolism, immune function, and other systems. The binding of leptin to its specific receptor activates various intracellular signaling pathways, including Janus kinase 2 (JAK2)/ signal transducer and activator of transcription 3 (STAT3), insulin receptor substrate (IRS)/phosphatidylinositol 3 kinase (PI3K...
Janus kinases (JAKs) are a family of cytoplasmatic tyrosine kinases that are attractive targets for the development of anti-inflammatory drugs given their roles in cytokine signaling. One question regarding JAKs and their inhibitors that remains under intensive debate is whether JAK inhibitors should be isoform selective. Since JAK3 functions are restricted to immune cells, an isoform-selective...
IFN-β inhibits the expansion of Th17 cells in active multiple sclerosis (AMS), and this might contribute to improve the clinical symptoms. The effectiveness of this inhibition, however, requires intact IFN-γ signaling in T cells. In this study, we report that both mRNA and cell surface expression of the signaling chain of the IFN-γ receptor (IFN-γR2) and its cognate tyrosine kinase JAK2 are enh...
