Neutralizing Abs constitute a pivotal mechanism of the adaptive immune response against HIV-1 infection. Yet, most of the Abs that appear in the circulation during HIV infection are nonneutralizing. In this study, we report a dramatic change of the neutralizing properties of a human Ab reactive with the nonneutralizing epitope termed cluster I on the HIV-1(More)
Connective tissue growth factor (CTGF) is a signaling molecule that primarily functions in extracellular matrix maintenance and repair. Increased Ctgf expression is associated with fibrosis in chronic organ injury. Studying the role of CTGF in fibrotic disease in vivo, however, has been hampered by perinatal lethality of the Ctgf null mice as well as the(More)
Conjugation of cytotoxic compounds to antibodies that bind to cancer-specific antigens makes these drugs selective in killing cancer cells. However, many of the compounds used in such antibody-drug conjugates (ADC) are substrates for the multidrug transporter MDR1. To evade the MDR1-mediated resistance, we conjugated the highly cytotoxic maytansinoid DM1 to(More)
The pathology of atherosclerotic lesions that develop in mouse models of atherosclerosis, such as those lacking apolipoprotein E or lacking the low density lipoprotein receptor, is very similar to that seen in human patients. Consequently, genetic approaches to studying atherosclerosis in these mouse models have produced a wealth of information relevant to(More)
Connective tissue growth factor (CTGF) is an important mediator of fibrosis; emerging evidence link changes in plasma and urinary CTGF levels to diabetic kidney disease. To further ascertain the role of CTGF in responses to high glucose, we assessed the consequence of 4 months of streptozotocin-induced diabetes in wild type (+/+) and CTGF heterozygous (+/-)(More)
The DDK syndrome is an early embryonic lethal phenotype observed in crosses between females of the DDK inbred mouse strain and many non-DDK males. Lethality results from an incompatibility between a maternal DDK factor and a non-DDK paternal gene, both of which have been mapped to the Ovum mutant (Om) locus on mouse chromosome 11. Here we define a 465-kb(More)
Posterior reversible encephalopathy syndrome (PRES) is a rare neurological condition associated with a variety of underlying conditions, including preeclampsia. The headache associated with PRES may be indistinguishable from post-dural puncture headache, which may result in diagnostic delay. We report a case of PRES that was initially diagnosed as(More)

A major antigenic constituent of the inner membrane of Escherichia coli ML308-225 was identified as a 28.5-kilodalton lipoprotein containing covalently bound glycerol and palmitate. This lipoprotein corresponded to antigen 47 in the crossed immunoelectrophoresis profile of membrane vesicles (P. Owen and H.R. Kaback, Proc. Natl. Acad. Sci. USA 75:3148-3152,(More)
Triton X-100-insoluble residues from Micrococcus lysodeikticus membranes were analyzed by crossed immunoelectrophoresis after dispersal of the residues in sodium dodecyl sulfate (SDS). Conditions which produce no obvious distortion of the immunoprecipitate profile and which allow qualitative and quantitative analyses of the antigens present in the extracts(More)
