Enhanced Expression of Interferon-γ-Induced Antigen-Processing Machinery Components in a Spontaneously Occurring Cancer

open access: yesNeoplasia: An International Journal for Oncology Research, 2007
In human tumors, changes in the surface expression and/or function of major histocompatibility complex (MHC) class I antigens are frequently found and may provide malignant cells with a mechanism to escape control of the immune system. This altered human

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

open access: yesEmerging 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 ...

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

open access: yesInternational 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

open access: yesFrontiers 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

Regulation of Antigen Export to the Cytosol During Cross-Presentation

open access: yesFrontiers 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.

An Overview on ERAP Roles in Infectious Diseases

open access: yesCells, 2020
Endoplasmic reticulum (ER) aminopeptidases ERAP1 and ERAP2 (ERAPs) are crucial enzymes shaping the major histocompatibility complex I (MHC I) immunopeptidome. In the ER, these enzymes cooperate in trimming the N-terminal residues from precursors peptides,

Major histocompatibility class I antigens in the Lebanese population

open access: yesEastern Mediterranean Health Journal, 2021
Except for two reports on Lebanese immigrants, there have been no studies on the major histocompatibility [MHC] antigens in the Lebanese population. We describe the frequency and distribution of MHC class I antigens present in the A, B and C loci based on data obtained from 200 healthy unrelated individuals from different parts of Lebanon.

Palmitoylated antigens for the induction of anti-tumor CD8+ T cells and enhanced tumor recognition

open access: yesMolecular Therapy: Oncolytics, 2021
Induction of tumor-specific cytotoxic CD8+ T cells (CTLs) via immunization relies on the presentation of tumor-associated peptides in major histocompatibility complex (MHC) class I molecules by dendritic cells (DCs).

The Clinical Application of Neoantigens in Esophageal Cancer

open access: yesFrontiers in Oncology, 2021
Esophageal cancer (EC) is a common malignant tumor with poor prognosis, and current treatments for patients with advanced EC remain unsatisfactory. Recently, immunotherapy has been recognized as a new and promising approach for various tumors.
