“Ways in which the neonatal Fc-receptor is involved in autoimmunity”

Journal of Translational Autoimmunity, 2021
Since the neonatal IgG Fc receptor (FcRn) was discovered, its role has evolved from immunoglobulin recycling and biodistribution to antigen presentation and immune complex routing, bringing it to the center of both humoral and cellular immune responses ...

Robust expression of the human neonatal Fc receptor in a truncated soluble form and as a full-length membrane-bound protein in fusion with eGFP.

PLoS ONE, 2013
Studies on the neonatal Fc receptor (FcRn) have revealed a multitude of important functions in mammals, including protection of IgG and serum albumin (SA) from lysosomal degradation.

Binding to the neonatal Fc receptor enhances the pathogenicity of anti-desmoglein-3 antibodies in keratinocytes

Frontiers in Immunology
The neonatal Fc receptor (FcRn) is important for numerous cellular processes that involve antibody recycling and trafficking. A major function of FcRn is IgG recycling and half-life prolongation, and FcRn blockade results in a reduction of autoantibodies

Oral Fc-Coupled Preproinsulin Achieves Systemic and Thymic Delivery Through the Neonatal Fc Receptor and Partially Delays Autoimmune Diabetes

Frontiers in Immunology, 2021
Tolerogenic vaccinations using beta-cell antigens are attractive for type 1 diabetes prevention, but clinical trials have been disappointing. This is probably due to the late timing of intervention, when multiple auto-antibodies are already present.

The Fab region of IgG impairs the internalization pathway of FcRn upon Fc engagement

Nature Communications, 2022
Disrupting the association between the Immunoglobulin G constant fragment (Fc) and the neonatal Fc receptor (FcRn) by engineered antibodies is a promising strategy to reduce autoantibody levels in autoimmune diseases.

Fc receptor engagement of HIV-1 Env-specific antibodies in mothers and infants predicts reduced vertical transmission

Frontiers in Immunology, 2022
IntroductionInfants acquire maternal antibodies by Fc receptor transcytosis across the placenta during pregnancy. Fc receptors are expressed on immune cells and are important for activation of effector cell functions.MethodsIn this study, we evaluated Fc

In vivo pharmacokinetic enhancement of monomeric Fc and monovalent bispecific designs through structural guidance

Communications Biology, 2021
Lu Shan et al. present a structure-guided approach to engineer a monovalent form of the fragment crystallizable (Fc) region of an IgG4 antibody to adapt multiple versions of half-life extension modifications and bispecific targeting.

Neonatal EEG graded for severity of background abnormalities in hypoxic-ischaemic encephalopathy [PDF]

Sci Data 10, 129 (2023), 2022
This report describes a set of neonatal electroencephalogram (EEG) recordings graded according to the severity of abnormalities in the background pattern. The dataset consists of 169 hours of multichannel EEG from 53 neonates recorded in a neonatal intensive care unit.

The neonatal Fc receptor expression during macrophage differentiation is related to autophagy

Frontiers in Immunology, 2022
The neonatal Fc receptor (FcRn) plays a central role in recycling and biodistributing immunoglobulin G. FcRn is also involved in many physiological immune functions as well as pathological immune responses in cancer or autoimmune diseases.
