Type XI collagen is a structural component of the cartilage extracellular matrix and plays an important role in skeletal morphogenesis. As a step toward defining the molecular mechanisms responsible for the regulation of type XI collagen expression, we characterized the promoter region of the mouse alpha 2(XI) collagen gene (Coll1a2). We also generated(More)
We have previously observed that HIV-1 replication is suppressed in uninflamed lung and increased during tuberculosis. In vitro THP-1 cell–derived macrophages inhibited HIV-1 repli-cation after infection with Mycobacterium tuberculosis. Suppression of HIV-1 replication was associated with inhibition of the HIV-1 long terminal repeat (LTR) and induction of(More)
Mycoplasma pneumoniae (Mp) is a leading cause of community acquired pneumonia. Knowledge regarding Mp pneumonia obtained from animal models or human subjects has been discussed in many different reports. Accumulated expertise concerning this critical issue has been hard to apply clinically, and potential problems may remain undiscovered. Therefore, our(More)
Idiopathic pulmonary alveolar proteinosis (I-PAP) is a rare disease of unknown etiology in which the alveoli fill with lipoproteinaceous material. We report here that I-PAP is an autoimmune disease with neutralizing antibody of immunoglobulin G isotype against granulocyte/macrophage colony-stimulating factor (GM-CSF). The antibody was found to be present in(More)
Using the neural network algorithm with back-propagation training procedure, we analysed the zinc finger DNA binding protein sequences. We incorporated the characteristic patterns around the zinc finger motifs TFIIIA type (Cys-X2-5-Cys-X12-13-His-X2-5-His) and the steroid hormone receptor type (Cys-X2-5-Cys-X12-15-Cys-X2-5-Cys-X15-16-Cys-X4-5-Cys-X8-10-(More)
HIV-1 replication is markedly upregulated in alveolar macrophages (AM) during pulmonary tuberculosis (TB). This is associated with loss of an inhibitory CCAAT enhancer binding protein beta (C/EBPbeta) transcription factor and activation of nuclear factor (NF)-kappaB. Since the cellular immune response in pulmonary TB requires lymphocyte--macrophage(More)
We have previously developed a general method based on the statistical technique of discriminant analysis to predict splice junctions in eukaryotic mRNA sequences [Nakata, K., Kanehisa, M. and DeLisi, C. (1985) Nucleic Acids Res., 13, 5327-5340]. In order to evaluate further applicability of this method, we now analyze the promoter region of Escherichia(More)
Diffuse panbronchiolitis (DPB) is a chronic inflammatory airway disease predominantly affecting Asian populations. DPB is considered to be a complex genetic disease. Considering the mucous hypersecretion of the disease, we hypothesized that the transcriptional activity of mucin genes may be altered in DPB. We analyzed nucleotide sequences of regulatory(More)
High levels of granulocyte/macrophage-colony stimulating factor (GM-CSF) autoantibodies are thought to cause pulmonary alveolar proteinosis (PAP), a rare syndrome characterized by myeloid dysfunction resulting in pulmonary surfactant accumulation and respiratory failure. Paradoxically, GM-CSF autoantibodies have been reported to occur rarely in healthy(More)
