Noncovalent functionalization of carbon nanotubes for highly specific electronic biosensors

…, M Shim, Y Li, W Kim, PJ Utz… - Proceedings of the …, 2003 - National Acad Sciences
Novel nanomaterials for bioassay applications represent a rapidly progressing field of
nanotechnology and nanobiotechnology. Here, we present an exploration of single-walled
carbon nanotubes as a platform for investigating surface–protein and protein–protein …

Identification of a putative regulator of early T cell activation genes

JP Shaw, PJ Utz, DB Durand, JJ Toole… - …, 1988 - science.sciencemag.org
Molecules involved in the antigen receptor-dependent regulation of early T cell activation
genes were investigated with the use of functional sequences of the T cell activation-specific
enhancer of interleukin-2 (IL-2). One of these sequences forms a protein complex, NFAT-1 …

Autoantigen microarrays for multiplex characterization of autoantibody responses

…, JS Smolen, PO Brown, L Steinman, PJ Utz - Nature medicine, 2002 - nature.com
We constructed miniaturized autoantigen arrays to perform large-scale multiplex
characterization of autoantibody responses directed against structurally diverse
autoantigens, using submicroliter quantities of clinical samples. Autoantigen microarrays …

Immune inhibitory molecules LAG-3 and PD-1 synergistically regulate T-cell function to promote tumoral immune escape

…, JF Grosso, G Netto, MP Smeltzer, A Chaux, PJ Utz… - Cancer research, 2011 - AACR
Inhibitory receptors on immune cells are pivotal regulators of immune escape in cancer.
Among these inhibitory receptors, CTLA-4 (targeted clinically by ipilimumab) serves as a
dominant off-switch while other receptors such as PD-1 and LAG-3 seem to serve more …

RAG2 PHD finger couples histone H3 lysine 4 trimethylation with V (D) J recombination

…, D Carney, P Cheung, DN Ciccone, KL Walter, PJ Utz… - Nature, 2007 - nature.com
Nuclear processes such as transcription, DNA replication and recombination are
dynamically regulated by chromatin structure. Eukaryotic transcription is known to be
regulated by chromatin-associated proteins containing conserved protein domains that …

Protein microarrays with carbon nanotubes as multicolor Raman labels

…, X Wang, G Zhang, X Li, Z Liu, PJ Utz… - Nature …, 2008 - nature.com
The current sensitivity of standard fluorescence-based protein detection limits the use of
protein arrays in research and clinical diagnosis. Here, we use functionalized,
macromolecular single-walled carbon nanotubes (SWNTs) as multicolor Raman labels for …

Antigen microarray profiling of autoantibodies in rheumatoid arthritis

…, JW Drijfhout, WJ Van Venrooij, PJ Utz… - Arthritis & …, 2005 - Wiley Online Library
Objective Because rheumatoid arthritis (RA) is a heterogeneous autoimmune disease in
terms of disease manifestations, clinical outcomes, and therapeutic responses, we
developed and applied a novel antigen microarray technology to identify distinct serum …

Protein microarrays guide tolerizing DNA vaccine treatment of autoimmune encephalomyelitis

…, CP Genain, S Amor, T Olsson, PJ Utz… - Nature …, 2003 - nature.com
The diversity of autoimmune responses poses a formidable challenge to the development of
antigen-specific tolerizing therapy. We developed'myelin proteome'microarrays to profile the
evolution of autoantibody responses in experimental autoimmune encephalomyelitis (EAE) …

On-chip coupling of isoelectric focusing and free solution electrophoresis for multidimensional separations

…, KA Drouvalakis, JC Mikkelsen, PJ Utz… - Analytical …, 2003 - ACS Publications
We have developed an acrylic microfluidic device that sequentially couples liquid-phase
isoelectric focusing (IEF) and free solution capillary electrophoresis (CE). Rapid separation
(< 1 min) and preconcentration (73×) of species were achieved in the initial IEF dimension …

[HTML][HTML] Notch signals positively regulate activity of the mTOR pathway in T-cell acute lymphoblastic leukemia

SM Chan, AP Weng, R Tibshirani, JC Aster, PJ Utz - Blood, 2007 - Am Soc Hematology
Constitutive Notch activation is required for the proliferation of a subgroup of T-cell acute
lymphoblastic leukemia (T-ALL). Downstream pathways that transmit pro-oncogenic signals
are not well characterized. To identify these pathways, protein microarrays were used to …
