A high-level secretion system for the production of mouse-human chimeric antibody 21B2 (MHC 21B2) Fab fragment specific for human carcino embryonic antigen (hCEA) in Escherichia coli has been constructed. The genes encoding a light chain and an Fd fragment (a variable region and the CH1 domain of a heavy chain) of a mouse-human chimeric antibody were(More)
OBJECTIVE To assess the safety and efficacy of 4 concentrations of tazarotene cream in the treatment of facial photodamage. DESIGN Prospective weekly multicenter, investigator-masked, randomized, parallel-group study. SETTING University hospitals and clinical research centers. PATIENTS Three hundred forty-nine subjects with facial photodamage. (More)
Tazarotene (AGN 190168) is a new acetylenic retinoid which is effective for the topical treatment of patients with stable plaque psoriasis and mild to moderate acne vulgaris. Topical gel application provides direct delivery of tazarotene into the skin. At 10 hours after a topical application of 0.1% tazarotene gel to the skin of healthy individuals and(More)
Previous studies suggest that CD1 is a family of Ag-presenting molecules distantly related to those encoded by the MHC. However, of the four known human CD1 proteins, only CD1b has been shown to restrict Ag-specific T cell responses. In this study, we have shown that a second member of the human CD1 family, CD1c, could also mediate Ag presentation to T(More)
These in vitro studies indicate that N-oxidation of N-hydroxyamphetamine (NOHA) by rat liver homogenates yields phenylacetone oxime (PAOx) as the major metabolite. This oxidation was NADPH and oxygen dependent but was not appreciably increased in microsomes from phenobarbital-pretreated animals. The addition to microsomal incubations of superoxide dismutase(More)
The proteolytic processing of beta-amyloid precursor protein (APP) was analyzed and compared for familial Alzheimer's disease and normal lymphoid cells, focusing on beta-amyloid-harbouring peptides and the extracellular fragments released into the medium. Tris/tricine gel electrophoresis of anti-beta A4-(8-17)-immunoprecipitated peptides and subsequent(More)
The processing of beta-amyloid precursor protein (APP) and generation of beta-amyloid (Abeta) are associated with the pathophysiology of Alzheimer's disease (AD). As the proteases responsible for the process in the human brain have yet to be clarified, we have searched for activities capable of cleaving native brain APP in the human hippocampus. A 40-kDa(More)
To explore whether extracellular matrix components in human brain affect the deposition and aggregation of beta-amyloid containing peptides, human brain samples from patients with sporadic Alzheimer's disease and normal aged were analyzed by Western blot analysis. All major beta-amyloid-containing peptides contained epitope(s) which is recognized by anti(More)
Human brain homogenate proteins were analyzed for binding and processing activity in relation to brain beta-amyloid precursor protein (APP). The homogenate was purified by arginine-Sepharose 4B affinity chromatography, which traps proteins with affinity to certain groups of arginine residue, such as serine proteases and zymogens. A 69 kDa protein that masks(More)
Human brain proteins were partially purified by using arginine-Sepharose 4B affinity chromatography, which traps proteins having an affinity to certain groups of arginine residue, such as serine proteases and zymogens. Bound proteins were analyzed for binding and cleavage related to the brain beta-amyloid precursor protein (APP). They were then further(More)
