Previous work in our laboratory has shown that microvascular pericytes sort muscle and nonmuscle actin isoforms into discrete cytoplasmic domains (Herman, I. M., and P. A. D'Amore. 1985. J. Cell Biol. 101:43-52; DeNofrio, D.T.C. Hoock, and I. M. Herman. J. Cell. Biol. 109:191-202). Specifically, muscle (alpha-smooth) actin is present on the stress fibers(More)
We have recently cloned and characterized ankyrin-3 (also called ankyrin(G)), a new ankyrin that is widely distributed, especially in epithelial tissues, muscle, and neuronal axons (Peters, L.L., K.M. John, F.M. Lu, E.M. Eicher, A. Higgins, M. Yialamas, L.C. Turtzo, A.J. Otsuka, and S.E. Lux. 1995. J. Cell Biol. 130: 313-330). Here we show that in mouse(More)

We characterized the form and distribution of muscle and nonmuscle actin within retinal pericytes. Antibodies with demonstrable specificities for the actin isoforms were used in localization and immunoprecipitation experiments to identify those cellular domains that were enriched or deficient in one or several actin isoforms. Living pericyte behavior was(More)

Cytokines, growth factors, and other chemical messengers rely on a class of intracellular nonreceptor tyrosine kinases known as Janus kinases (JAKs) to rapidly transduce intracellular signals. A number of these cytokines are critical for lymphocyte development and mediating immune responses. JAK3 is of particular interest due to its importance in immune(More)
OBJECTIVE To assess the efficacy and safety of oral decernotinib (VX-509; Vertex Pharmaceuticals) monotherapy in a 12-week, randomized, double-blind, placebo-controlled, dose-ranging study of patients with rheumatoid arthritis (RA). METHODS Two hundred four adults with active RA who had been unsuccessfully treated with ≥1 disease-modifying antirheumatic(More)
While several therapeutic options exist, the need for more effective, safe, and convenient treatment for a variety of autoimmune diseases persists. Targeting the Janus tyrosine kinases (JAKs), which play essential roles in cell signaling responses and can contribute to aberrant immune function associated with disease, has emerged as a novel and attractive(More)
A series of SYK inhibitors based on the phenylamino pyrimidine thiazole lead 4 were prepared and evaluated for biological activity. Lead optimization provided compounds with nanomolar K(i)'s against SYK and potent inhibition in mast cell degranulation assays.
