Flavivirus infection up-regulates the expression of class I and class II major histocompatibility antigens on and enhances T cell recognition of astrocytes in vitro

Journal of Neuroimmunology, 1989
West Nile virus (WNV) infection of astrocytes can up-regulate their expression of both class I and class II major histocompatibility complex (MHC) antigens as determined by flow cytometry with monoclonal antibodies specific for class I and class II MHC ...

Structural analysis of the adenovirus type 2 E3/19K protein using mutagenesis and a panel of conformation-sensitive monoclonal antibodies [PDF]

, 2008
The E3/19K protein of human adenovirus type 2 (Ad2) was the first viral protein shown to interfere with antigen presentation. This 25 kDa transmembrane glycoprotein binds to major histocompatibility complex (MHC) class I molecules in the endoplasmic ...

Interferon-gamma-activated macrophages infected with Burkholderia cenocepacia process and present bacterial antigens to T-cells by class I and II major histocompatibility complex molecules

Emerging Microbes and Infections, 2020
Burkholderia cenocepacia is an emerging opportunistic pathogen for people with cystic fibrosis and chronic granulomatous disease. Intracellular survival in macrophages within a membrane-bound vacuole (BcCV) that delays acidification and maturation into ...

Impaired Intracellular Transport and Cell Surface Expression of Nonpolymorphic HLA-E [PDF]

, 1992
The assembly of the classical, polymorphic major histocompatibility complex class I molecules in the endoplasmic reticulum requires the presence of peptide ligands and ~2-microglobulin (~2m). Formation of this trimolecular complex is a prerequisite for e~

Is There any Greater Possibility in Finding HLA-identical Unrelated Hematopoietic Stem Cell Donors among Thalassemia Families for Transplantation of Thalassemia Patients? [PDF]

International Journal of Hematology-Oncology and Stem Cell Research, 2004
Background: Thalassemia is probably the most common single gene disorder causing a major public health problem in the world. Currently, allogenic hematopoietic stem cell transplantation (HSCT) is the only curative therapy for thalassemia.

Endogenous antigen presentation of MHC class II epitopes through non-autophagic pathways

Frontiers in Immunology, 2015
Antigenic peptides presented by major histocompatibility complex (MHC) class II molecules are generally derived from exogenous proteins acquired by antigen presenting cells. However, in some circumstances, MHC class II molecules can present intracellular

Downregulation of major histocompatibility complex class I in bovine papillomas [PDF]

, 2004
Bovine papillomavirus (BPV) induces papillomas in cattle; in the great majority of cases, these regress due to the host immune response, but they can persist and progress to malignancy.

Regulation of Antigen Export to the Cytosol During Cross-Presentation

Frontiers in Immunology, 2019
Cross-priming refers to the induction of primary cytotoxic CD8+ T cell responses to antigens that are not expressed in antigen presenting cells (APCs) responsible for T cell priming.

Metastasis on pause: How dormant tumor cells stay hidden within the tumor microenvironment and evade immune surveillance

Molecular Oncology, EarlyView.
Dormant cancer cells can hide in distant organs for years, evading treatment and the immune system. This review highlights how signals from the surrounding tissue and immune environment keep these cells inactive or trigger their reawakening. Understanding these mechanisms may help develop therapies to eliminate or control dormant cells and prevent ...
