Mammalian non-classical major histocompatibility complex I and its receptors: Important contexts of gene, evolution, and immunity

TLDR
This review highlights the new updates of the mammalian nonclassical MHC-I molecules in terms of their gene organization, evolutionary perspective and their role in immunity.
Abstract
The evolutionary conserved, less-polymorphic, nonclassical major histocompatibility complex (MHC) class I molecules: Qa-1 and its human homologue human leukocyte antigen-E (HLA-E) along with HLA-F, G and H cross-talk with the T-cell receptors and also interact with natural killer T-cells and other lymphocytes. Moreover, these nonclassical MHC molecules are known to interact with CD94/NKG2 heterodimeric receptors to induce immune responses and immune regulations. This dual role of Qa-1/HLA-E in terms of innate and adaptive immunity makes them more interesting. This review highlights the new updates of the mammalian nonclassical MHC-I molecules in terms of their gene organization, evolutionary perspective and their role in immunity.

Rediscovering Beta-2 Microglobulin As a Biomarker across the Spectrum of Kidney Diseases.

TL;DR: The role of beta-2 microglobulin (β2M) as a biomarker in patients with chronic kidney disease and end-stage renal disease is revisited and emerging proteomic data suggesting that β2M is a promising marker of chronic allograft nephropathy is noted.

HLA-E expression by gynecological cancers restrains tumor-infiltrating CD8+ T lymphocytes

TL;DR: This article investigated HLA-E protein expression on tissue sections of 420 ovarian and cervical cancers and found equal or higher levels than normal counterpart epithelia in 80% of the tumors.

Classical and non-classical HLA class I aberrations in primary cervical squamous- and adenocarcinomas and paired lymph node metastases

TL;DR: These results strengthen the idea of tumor immune escape variants leading to metastasis and warrant further analysis of HLA expression as a biomarker for patient selection for CTL- and NK- cell based immunotherapeutic intervention.

HNRNPR Regulates the Expression of Classical and Nonclassical MHC Class I Proteins.

TL;DR: It is demonstrated that HNRNPR binds MHC class I mRNAs in their 3′ untranslated regions and enhances their stability and consequently their expression, and modulates the cytotoxic activity of NK cells.

In search of the 'missing self': MHC molecules and NK cell recognition.

TL;DR: In vivo studies with H-2-deficient targets that support the 'missing self' hypothesis are reviewed and testable predictions for how MHC class I molecules act in cases where they control a rate-limiting step in the NK cell-target interaction are derived.

CD1d-restricted and TCR-mediated activation of valpha14 NKT cells by glycosylceramides.

TL;DR: Glycosylceramide-mediated proliferative responses of Valpha14 NKT cells were abrogated by treatment with chloroquine-concanamycin A or by monoclonal antibodies against CD1d/Vbeta8, CD40/CD40L, or B7/CTLA-4/CD28, but not by interference with the function of a transporter-associated protein.

HLA-E binds to natural killer cell receptors CD94/NKG2A, B and C

TL;DR: The identification of ligands for HLA-E is reported, which shows that a subset of HLA class I alleles has been shown to inhibit killing by CD94/NKG2A+ NK-cell clones, and only the HLA alleles that possess a leader peptide capable of upregulating Hla-E surface expression confer resistance toNK-cell-mediated lysis.

TL;DR: The specificity and function of mouse NK1 T cells are reviewed, the relationship of this lineage to mainstream T cells and NK cells is discussed, and the novel regulatory pathway, which straddles the innate and the adaptive immune systems, is discussed.
