Multitasking by exploitation of intracellular transport functions: the many faces of FcRn

ES Ward, RJ Ober - Advances in immunology, 2009 - Elsevier
The MHC Class I-related receptor, FcRn, transports antibodies of the immunoglobulin G (IgG)
class within and across a diverse array of different cell types. Through this transport, FcRn …

Fisher information theory for parameter estimation in single molecule microscopy: tutorial

J Chao, ES Ward, RJ Ober - JOSA A, 2016 - opg.optica.org
Estimation of a parameter of interest from image data represents a task that is commonly
carried out in single molecule microscopy data analysis. The determination of the positional …

FcRn: from molecular interactions to regulation of IgG pharmacokinetics and functions

DK Challa, R Velmurugan, RJ Ober, E Sally Ward - Fc Receptors, 2014 - Springer
The neonatal Fc receptor, FcRn, is related to MHC class I with respect to its structure and
association with β 2 microglobulin (β 2 m). However, by contrast with MHC class I molecules, …

[HTML][HTML] Localization accuracy in single-molecule microscopy

RJ Ober, S Ram, ES Ward - Biophysical journal, 2004 - cell.com
One of the most basic questions in single-molecule microscopy concerns the accuracy with
which the location of a single molecule can be determined. Using the Fisher information …

Differences in promiscuity for antibody–FcRn interactions across species: implications for therapeutic antibodies

RJ Ober, CG Radu, V Ghetie… - International …, 2001 - academic.oup.com
Preclinical tests of therapeutic antibodies are frequently carried out in mice to evaluate
pharmacokinetics and efficacy. However, the observation that mouse IgG are cleared rapidly from …

Engineering the Fc region of immunoglobulin G to modulate in vivo antibody levels

C Vaccaro, J Zhou, RJ Ober, ES Ward - Nature biotechnology, 2005 - nature.com
We have engineered the Fc region of a human immunoglobulin G (IgG) to generate a mutated
antibody that modulates the concentrations of endogenous IgGs in vivo. This has been …

Increasing the serum persistence of an IgG fragment by random mutagenesis

…, C Radu, D Matesoi, C Medesan, RJ Ober… - Nature …, 1997 - nature.com
The major histocompatibility complex (MHC) class l-related receptor FcRn is involved in
regulating serum gammaglobulin (IgG) levels in mice. With the aim of increasing the serum half-…

Visualizing the site and dynamics of IgG salvage by the MHC class I-related receptor, FcRn

RJ Ober, C Martinez, C Vaccaro, J Zhou… - The Journal of …, 2004 - journals.aai.org
The MHC class I-related receptor, FcRn, plays a central role in regulating the serum levels of
IgG. FcRn is expressed in endothelial cells, suggesting that these cells may be involved in …

The MHC class I-related receptor, FcRn, plays an essential role in the maternofetal transfer of γ-globulin in humans

M Firan, R Bawdon, C Radu, RJ Ober… - International …, 2001 - academic.oup.com
The transfer of maternal γ-globulin (IgG) provides the neonate with humoral immunity during
early life. In humans, maternal IgG is transported across the placenta during the third …

Exocytosis of IgG as mediated by the receptor, FcRn: an analysis at the single-molecule level

RJ Ober, C Martinez, X Lai, J Zhou… - Proceedings of the …, 2004 - National Acad Sciences
IgG transport within and across cells is essential for effective humoral immunity. Through a
combination of biochemical and in vivo analyses, the MHC class I-related neonatal Fc …
