Uterine growth factors are potential effector molecules in embryo growth signaling pathways. Pig uterine luminal flushings contained a heparin-binding growth factor (HBGF) that required 0.8 M NaCl for elution from heparin columns and was termed HBGF-0.8. This factor, which was heat- and acid-labile and of Mr 10,000 as assessed by gel filtration, stimulated(More)
We tested to determine if planned multiple exposures to autologous HIV in pediatric patients with HIV-1 infection will induce cellular immunity that controls viremia. A prospective multicenter study of aviremic pediatric patients on highly active antiretroviral therapy who underwent progressively longer antiretroviral treatment interruptions in cycles(More)
Diurnal plasma insulin and glucose concentrations were studied in six diabetic patients, each treated with five different insulin regimes. Subcutaneous soluble insulin was too slow and long acting for physiological replacement of the normal insulin response to meals, but the peak insulin levels were higher than the postprandial levels of normal subjects.(More)
Connective tissue growth factor (CTGF) is a mitogenic and chemotactic factor for cultured fibroblasts that has been implicated in wound healing, fibrotic disorders and uterine function. Although the primary translational products of the mouse, human and pig CTGF (mCTGF, hCTGF, pCTGF) genes are predicted to be secreted and of approximate M(r) 38,000, 10 kDa(More)
Heparin-binding EGF-like growth factor (HB-EGF), a potent epithelial cell mitogen, has been identified in human burn blister fluid and excised human burn wounds. Topical application of HB-EGF to murine partial-thickness scald burns accelerated reepithelialization, increased keratinocyte proliferation, and enhanced production of endogenous transforming(More)
Circulating human immunodeficiency virus type 1 (HIV-1)-specific cytotoxic T lymphocytes (CTL) are seen less frequently in unstimulated peripheral blood mononuclear cells (PBMC) from children with vertically acquired HIV infection than in PBMC from HIV-infected adults. HIV-1 Gag-, reverse transcriptase (RT)-, and envelope (Env)-specific cytotoxic activity(More)
The T cell receptor (TCR) repertoires of 24 human immunodeficiency virus (HIV) type 1-infected children were determined by flow cytometry in combination with sequencing of the highly variable TCR complementarity-determining region 3, permitting a quantitative and qualitative assessment of TCR repertoire. Expanded subsets of CD8(+) cells expressing a(More)
BACKGROUND & AIMS Heparin-binding epidermal growth factor-like growth factor (HB-EGF) is produced as a type-I, single-pass transmembrane protein that can be cleaved to release a diffusible peptide. HB-EGF, often overexpressed in damaged or diseased epithelium, is normally expressed in pancreatic islets, but its function is not understood. METHODS To(More)
Heparin-binding epidermal growth factor-like growth factor (HB-EGF) is initially synthesized as a membrane bound protein that is subsequently processed to yield an approximately 74 amino acid secreted product. To investigate the biological activities of HB-EGF and its role(s) in tumor formation, the full-length HB-EGF cDNA was cloned under the regulation of(More)
We studied the in vitro effects of IL-12 on HIV-1-specific CTL lines derived from PBMC of HIV-1-infected children. HIV-1-specific CTL lines were derived by limiting dilution following Ag-specific stimulation of PBMC from HIV-1-infected children and were maintained with repeated anti-CD3 stimulation. Following incubation with IL-12 for 5 to 7 days,(More)
