Cytotoxic necrotizing factor types 1 and 2 (CNF1 and -2) produced by pathogenic Escherichia coli strains have 90% conserved residues over 1,014-amino-acid sequences. Both CNFs are able to provoke a remarkable increase in F-actin structures in cultured cells and covalently modify the RhoA small GTPases. In this study, we demonstrated that CNF2 reduced RhoA(More)
BACKGROUND AND PURPOSE We conducted preclinical and clinical studies to examine the pharmacological, particularly cardiac, effects of amiselimod (MT-1303), a second-generation sphingosine 1-phosphate (S1P) receptor modulator, designed to reduce the bradycardia associated with fingolimod and other S1P receptor modulators. EXPERIMENTAL APPROACH The(More)
Rho is a major small GTP-binding protein that is involved in the regulation of various cell functions, including proliferation and cell migration, through activation of multiple signaling molecules in various types of cells. We studied its roles in synovial fibroblasts (SFs) in patients with rheumatoid arthritis (RA) and clarified its relevance to RA(More)
OBJECTIVE We examined the association of outdoor air pollution and meteorological parameters with primary care visits (PCVs) at night due to asthma attack. SETTING A case-crossover study was conducted in a primary care clinic in Himeji City, Japan. PARTICIPANTS Participants were 1447 children aged 0-14 years who visited the clinic with an asthma attack(More)
