Escape from the phagosome: the explanation for MHC-I processing of mycobacterial antigens?

Frontiers in Immunology, 2012
Mycobacterium tuberculosis (Mtb) is thought to live in an altered phagosomal environment. In this setting, the mechanisms by which mycobacterial antigens access the major histocompatibility class I (MHC-I) processing machinery remain incompletely ...

Serum Levels of Classical HLA Class I Antigen in HIV-Infected patients during antiretroviral therapy. Correlation with the clinical outcome

Journal of Biological Research, 2009
Aim. Human major histocompatibility complex class I antigens (HLA-A, -B, and -C) are heterodimetric molecules composed of a heavy chain non covalently associated with an invariant protein known as B2-microglobulin. Besides being expressed on the membrane

EVALUATION OF HUMAN LEUKOCYTE ANTIGEN CLASS I AND II ANTIGENS IN HELICOBACTER PYLORI-POSITIVE PEDIATRIC PATIENTS WITH ACTIVE GASTRITIS AND DUODENAL ULCER

Arquivos de Gastroenterologia, 2017
BACKGROUND: As being the first bacteria determined to be carcinogenic, Helicobacter pylori (H. pylori) is a pathogen localized in the stomach in more than half of the world population.

Infectious Diseases and Immunity: Special Reference to Major Histocompatibility Complex

Emerging Infectious Diseases, 1997
Human leukocyte antigens (HLAs) are an inherent system of alloantigens, which are the products of genes of the major histocompatibility complex (MHC).

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

Neoplasia: 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

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 ...

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

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.
