Manipulating IL-2 availability amid presentation of donor MHC antigens suppresses murine alloimmune responses by inducing regulatory T cells. [PDF]

open access: yesPLoS ONE, 2010
BACKGROUND: Major histocompatibility complex (MHC) antigens are important for alloimmune responses as well as immune tolerance. Previous studies have shown that presentation of donor MHC antigens by donor-specific transfusion prior to or upon ...

Dendritic cells crosspresent antigens from live B16 cells more efficiently than from apoptotic cells and protect from melanoma in a therapeutic model. [PDF]

open access: yesPLoS ONE, 2011
Dendritic cells (DC) are able to elicit anti-tumoral CD8(+) T cell responses by cross-presenting exogenous antigens in association with major histocompatibility complex (MHC) class I molecules.

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

open access: yesFrontiers 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

open access: yesJournal 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

Genetic and serological heterogeneity of the supertypic HLA-B locus specificities Bw4 and Bw6 [PDF]

open access: yes, 1989
Gene cloning and sequencing of the HLA-B locus split antigens B38 (B16.1) and B39 (B16.2) allowed localization of their subtypic as well as their public specificities HLA-Bw4 or -Bw6 to the c~-helical region of the c~ 1 domain flanked by the amino acid ...

Infectious Diseases and Immunity: Special Reference to Major Histocompatibility Complex

open access: yesEmerging 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).

Determination of a predictive cleavage motif for eluted major histocompatibility complex class II ligands [PDF]

open access: yes, 2018
CD4+ T cells have a major role in regulating immune responses. They are activated by recognition of peptides mostly generated from exogenous antigens through the major histocompatibility complex (MHC) class II pathway.

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

Testing the theory of immune selection in cancers that break the rules of transplantation [PDF]

open access: yes, 2009
Modification of cancer cells likely to reduce their immunogenicity, including loss or down-regulation of MHC molecules, is now well documented and has become the main support for the concept of immune surveillance.

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

open access: yesArquivos 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.
