To investigate the role of peritoneal mesothelial cells in regulating hematopoiesis, as well as inflammation, healing, and tissue regeneration processes, long-term cultures of peritoneal mesothelial cells from human endocavitarian fluids were established. The purity of the cell population was assessed by morphologic and immunocytochemical criteria. Five(More)
Short peptide fragments of human and murine interleukin 1 (IL 1) were synthesized on the basis of their predicted exposure on the surface of the molecule in an attempt to identify the minimal structure responsible for the immunostimulatory activity of IL 1. One of these peptides, a fragment of nine residues of human IL 1 beta (VQGEESNDK, fragment 163-171),(More)
A preliminary model has been calculated for the activating interaction of the interleukin 1 receptor (IL-1R) accessory protein IL-1RAcP with the ligand/receptor complex IL-1beta/IL-1R(I). First, IL-1RAcP was modeled on the crystal structure of IL-1R(I) bound to IL-1beta. Then, the IL-1RAcP model was docked using specific programs to the crystal structure of(More)
The stimulating effect of a synthetic nonapeptide (fragment 163-171) of human interleukin 1 beta (IL-1 beta) on antibody responses to both T helper-dependent and T helper-independent antigens was investigated. It was shown that the nonapeptide enhanced the antibody response, as evaluated in the hemolytic plaque assay, of spleen cells from mice immunized(More)
IL-1 binds to two types of receptors on the cell membrane, of which only type I (IL-1RI) transduces signals in concert with the coreceptor IL-1 receptor accessory protein (IL-1RAcP) while type II (IL-1RII) allegedly functions solely as ligand sink and decoy receptor without participating in IL-1 signaling. To investigate the regulatory role of IL-1RII on(More)
The synthetic nonapeptide VQGEESNDK, corresponding to the fragment 163-171 of human IL-1 beta, showed in vivo immunomodulatory capacities qualitatively and quantitatively comparable to those of the mature human IL-1 beta protein. In fact, both IL-1 beta and the 163-171 fragment stimulated the immune response of normal mice and restored immune reactivities(More)
The IL-1 type II receptor (decoy RII) is a nonsignaling molecule the only established function of which is to capture IL-1 and prevent it from interacting with signaling receptor. The decoy RII is released in a regulated way from the cell surface. Here, we reported that hydroxamic acid inhibitors of matrix metalloproteases inhibit different pathways of(More)
In order to better characterize the mechanisms which regulate the immune response at the pulmonary level, the effects of beta-interferon (IFN-beta) and lymphokines (LK) on prostaglandin E (PGE) release and the suppressive capacity of mouse resident alveolar (AM phi) and pleural macrophages (PlM phi) were investigated in comparison with peritoneal(More)
The relatively restricted nature of children’s use of information and communications technologies (ICTs) inside the school setting has long been noted by researchers. With this in mind, this article offers a grounded analysis of drawings collected from 355 primary pupils (years three to six) from five English primary schools depicting desired future forms(More)
