CONTEXT Alterations in megakaryocyte morphology are the hallmark of myeloproliferative neoplasms (MPNs). These neoplasm are also associated with Janus kinase 2 (JAK2) V617F mutation in nearly 95% patients with polycythemia vera (PV), 40% patients of essential thrombocythemia (ET) and 50% patients of myelofibrosis (MF). The utility of megakaryocyte morphology in these disorders in correlation wi...
JAK2 is a member of the Janus kinase (JAKs) family of non-receptor protein tyrosine kinases, which includes JAK1-3 and TYK2. JAKs serve as the cytoplasmic signaling components of cytokine receptors and are activated through cytokine-mediated trans-phosphorylation, which leads to receptor phosphorylation and recruitment and phosphorylation of signal transducer and activator of transcription (STA...
JAK2, a member of the Janus kinase (JAK) family of protein tyrosine kinases (PTKs), is an important intracellular mediator of cytokine signaling. Mutations of the JAK2 gene are associated with hematologic cancers, and aberrant JAK activity is also associated with a number of immune diseases, including rheumatoid arthritis. Accordingly, the development of JAK2-specific inhibitors has tremendous ...
Receptor transactivation, i.e., interaction between unrelated receptor systems, is a growing theme in cytokine and growth factor signaling. In this study we reveal for the first time the ability of IFN-alpha to transactivate gp130 in myeloma cells. An epidermal growth factor receptor/gp130 chimeric receptor previously shown by us to transactivate endogenous gp130, provided a complementary tool ...
The Janus kinase inhibitor upadacitinib is a potential treatment for psoriatic arthritis. efficacy and safety of as compared with adalimumab, tumor necrosis factor α inhibitor, in patients who have an inadequate response to nonbiologic disease-modifying antirheumatic drugs are unclear.
The common gamma-chain (gamma(c)) is an indispensable subunit of the functional receptor complexes for IL-4, IL-7, IL-9, and IL-15 as well as IL-2. Here we show that the gamma(c) is also shared with the IL-21R complex. Although IL-21 binds to the IL-21R expressed on gamma(c)-deficient ED40515(-) cells, IL-21 is unable to transduce any intracytoplasmic signals. However, in EDgamma-16 cells, a ga...
