Vascular cell adhesion molecule-1 (VCAM1) is a member of the immunoglobulin (Ig) superfamily which interacts with the integrin very late antigen-4 (VLA4). The VCAM1/VLA4 interaction mediates both adhesion and signal transduction and is thought to play an important role in inflammatory and immune responses in vivo. VCAM1 cDNAs cloned from mouse, rat, rabbit,(More)
We have previously shown that the tat protein of HIV-1 can be used as a carrier to promote the intracellular delivery of heterologous proteins. Here we have tested if the tat-delivery technology can be used to direct MHC class I presentation of native protein, using ovalbumin (OVA) as a model system. We show that a tat-ovalbumin conjugate (tatOVA) can be(More)
Despite the potential of type 1 interferons (IFNs) for the treatment of cancer, clinical experience with IFN protein therapy of solid tumors has been disappointing. IFN-beta has potent antiproliferative activity against most human tumor cells in vitro in addition to its known immunomodulatory activities. The antiproliferative effect, however, relies on(More)
Vascular cell adhesion molecule-1 (VCAM1) is a member of the immunoglobulin (Ig) superfamily which interacts with the integrin very late antigen 4 (VLA4). We have cloned the cDNAs for both murine and rat VCAM1 from endotoxin-treated lung libraries. Both sequences encode proteins with seven extracellular Ig-like domains, which show 75.9% and 76.9% identity,(More)
Vascular cell adhesion molecule-1 (VCAM1) of the Ig superfamily is induced by the inflammatory cytokines interleukin-1 and tumor necrosis factor on human umbilical vein endothelial cells (HUVECs). It binds to mononuclear leukocytes via the integrin VLA-4. We have cloned and expressed a cDNA encoding a new form of human VCAM1 containing an additional Ig(More)
Vascular cell adhesion molecule-1 (VCAM1) is a member of the immunoglobulin (Ig) superfamily which interacts with the integrin very late antigen-4 (VLA4). The VCAM1/VLA4 interaction mediates both adhesion and signal transduction and is thought to play an important role in inflammatory and immune responses in vivo. The major form of human VCAM1 contains(More)
Disulfide-rich peptide toxins found in the secretions of venomous organisms such as snakes, spiders, scorpions, leeches, and marine snails are highly efficient and effective tools for novel therapeutic drug development. Venom peptide toxins have been used extensively to characterize ion channels in the nervous system and platelet aggregation in haemostatic(More)
