ATGs help MHC class II, but inhibit MHC class I antigen presentation [PDF]

Autophagy, 2016
We have recently shown that the LC3/Atg8 lipidation machinery of macroautophagy is involved in the internalization of MHC class I molecules. Decreased internalization in the absence of ATG5 or ATG7 leads to MHC class I surface stabilization on dendritic cells and macrophages, resulting in elevated CD8(+) T cell responses during viral infections and ...

Insights into the ancestral organisation of the mammalian MHC class II region from the genome of the pteropid bat, Pteropus alecto

BMC Genomics, 2017
Background Bats are an extremely successful group of mammals and possess a variety of unique characteristics, including their ability to co-exist with a diverse range of pathogens.

Antibody-mediated rejection of arterialised venous allografts is inhibited by immunosuppression in rats. [PDF]

PLoS ONE, 2014
OBJECTIVES AND DESIGN: We determined in a rat model (1) the presence and dynamics of alloantibodies recognizing MHC complexes on quiescent Brown-Norway (BN) splenic cells in the sera of Lewis (LEW) recipients of Brown-Norway iliolumbar vein grafts under ...

Reduced vascular leakage correlates with breast carcinoma T regulatory cell infiltration but not with metastatic propensity

Molecular Oncology, EarlyView.
A mouse model for vascular normalization and a human breast cancer cohort were studied to understand the relationship between vascular leakage and tumor immune suppression. For this, endothelial and immune cell RNAseq, staining for vascular function, and immune cell profiling were employed.

Cell surface interactome analysis identifies TSPAN4 as a negative regulator of PD‐L1 in melanoma

Molecular Oncology, EarlyView.
Using cell surface proximity biotinylation, we identified tetraspanin TSPAN4 within the PD‐L1 interactome of melanoma cells. TSPAN4 negatively regulates PD‐L1 expression and lateral mobility by limiting its interaction with CMTM6 and promoting PD‐L1 degradation.

Major Histocompatibility Complex (MHC) Genes and Disease Resistance in Fish

Cells, 2019
Fascinating about classical major histocompatibility complex (MHC) molecules is their polymorphism. The present study is a review and discussion of the fish MHC situation. The basic pattern of MHC variation in fish is similar to mammals, with MHC class I

Ubiquitin-dependent control of class II MHC localization is dispensable for antigen presentation and antibody production. [PDF]

PLoS ONE, 2011
Controlled localization of class II MHC molecules is essential for proper class II MHC-restricted antigen presentation and the subsequent initiation of an adaptive immune response.

The Aging Blood: Cellular Origins, Circulating Drivers, and Therapeutic Potential

Aging and Cancer, EarlyView.
As a conduit linking all organs, the blood system both reflects and actively drives systemic aging. This review highlights how circulating pro‐aging and antiaging factors and age‐associated hematopoietic stem cell dysfunction contribute to immunosenescence and multi‐organ decline, positioning the hematopoietic system as a target for aging intervention.

MHC class I and class II structures

Current Opinion in Immunology, 1997
The basic structures of MHC class I and class II molecules are now well established. Over the past twelve months structural data on MHC class I molecules have provided details of the peptide binding groove for a number of alleles and have elaborated the mechanisms that allow binding of a range of peptides.

Olink Proteomics Analysis Reveals Heterogeneous Responses to FcRn Blockade in Anti‐AChR Antibody‐Positive Myasthenia Gravis: FGF‐19 as a Novel Biomarker

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective This study aimed to systematically observe the clinical manifestations, immune cell subsets, and dynamic changes in serological indicators in patients with myasthenia gravis (MG) before and after efgartigimod (EFG) treatment. Methods We analyzed the baseline data, laboratory parameters, and lymphocyte subset proportions in MG ...
