Heparin-binding (HB) epidermal growth factor (EGF)-like growth factor (HB-EGF), a member of the EGF protein family, is a potent mitogen for fibroblasts, smooth muscle cells, and keratinocytes that was initially identified as a secreted product of macrophage-like cells. HB-EGF and EGF appear to act on target cells utilizing the same receptor, but HB-EGF is(More)
IL-10 is an 18-kDa cytokine with a key role in homeostatic control of inflammatory and immune responses. We have investigated how transcription of the IL-10 gene is regulated, so as to be able to understand the circumstances of IL-10 expression in both health and disease. In the mouse, IL-10 gene expression is regulated by a TATA-type promoter with a(More)
IL-10 is an 18-kDa immunoregulatory cytokine the transcription of which is controlled by the ubiquitously expressed transcription factors Sp1 and Sp3. Although many cell types express IL-10 mRNA, not all make detectable amounts of protein, and levels of protein expression vary enormously. We show here that much of this variation can be accounted for by(More)
IL-18 (also known as IFN-gamma-inducing factor), although structurally unrelated to IL-12, shares with it the role of activating NK cells and polarizing T cells toward Th1 cell function. To understand how the IL-18 gene (and consequently Th1 function) is regulated, we have determined the gene structure and investigated the mechanisms of transcriptional(More)
Interleukin-12 (IL-12) is a heterodimeric cytokine composed of p35 and p40 subunits and is required for induction of T helper 1 (Th1) responses. Knowledge of how the IL-12 gene is regulated will permit an understanding of susceptibility and resistance to pathogenic microbes and to autoiummune diseases. In this report, we provide the gene structures,(More)
Three ichthyotoxic peptides, pardaxins P-I to P-3, have been isolated from the defense secretion of the sole Pardachirus pavoninus. Pavoninins, the steroid glycosides with shark-repelling ability, had previously been isolated therefrom. Each pardaxin consists of 33 amino acid residues having a distinctly hydrophilic carboxyl terminal region and a(More)
As part of an ongoing study of discourse structure of natural texts, we have identified a particular class of propositions that affect the bearer's perception of the coherence and communicated content of texts. As an example, if the text (spoken in a suitable situation) is: "I'm hungry. Let's go to the Fuji Gardens." then the most natural interpretation is(More)
CD59 is a complement regulatory protein and may also act as a signal-transducing molecule. CD59 transgenic mice have been generated using a CD59 minigene (CD59 minigene-1). Although this minigene contained a 4.6-kilobase pair 5'-flanking region from the human CD59 gene as a promoter, the expression levels of the CD59 mRNA were substantially lower than those(More)
Human CD52 (CAMPATH-1 antigen) is an abundant surface molecule on lymphocytes and a favoured target for lymphoma therapy and immunosuppression. It comprises a small glycosylphosphatidylinositol (GPI) anchored peptide to which a large carbohydrate moiety is attached. Structurally similar proteins include the proposed mouse homologue, B7 antigen (B7-Ag; not(More)
