KIR2DL2/2DL3-E(35) alleles are functionally stronger than -Q(35) alleles. [PDF]

, 2016
KIR2DL2 and KIR2DL3 segregate as alleles of a single locus in the centromeric motif of the killer cell immunoglobulin-like receptor (KIR) gene family. Although KIR2DL2/L3 polymorphism is known to be associated with many human diseases and is an important

Cellular Identity Crisis: RD3 Loss Fuels Plasticity and Immune Silence in Progressive Neuroblastoma

Advanced Science, EarlyView.
Researchers discovered that therapy‐induced loss of RD3 protein in neuroblastoma triggers a dangerous shift: cancer cells become more stem‐like, invasive, and resistant to treatment while evading immune detection. RD3 loss suppresses antigen presentation and boosts immune checkpoints, creating an immune‐silent environment.

ZBTB21 Is a Dual Suppressor of Pyroptosis and MHC‐I Antigen Presentation That Promotes Tumor Immune Evasion

Advanced Science, EarlyView.
ZBTB21 is a transcription factor that epigenetically suppresses pyroptosis and MHC‐I antigen presentation, enabling tumor immune evasion. Genetic ablation of ZBTB21 activates pyroptotic cell death and enhances antigen presentation, recruiting CD8+ T cells to overcome immune checkpoint blockade resistance.

T Cell Exhaustion in Cancer Immunotherapy: Heterogeneity, Mechanisms, and Therapeutic Opportunities

Advanced Science, EarlyView.
T cell exhaustion limits immunotherapy efficacy. This article delineates its progression from stem‐like to terminally exhausted states, governed by persistent antigen, transcription factors, epigenetics, and metabolism. It maps the exhaustion landscape in the TME and proposes integrated reversal strategies, providing a translational roadmap to overcome

Enhancing Natural Killer and CD8 + T Cell-Mediated Anticancer Cytotoxicity and Proliferation of CD8 + T Cells with HLA-E Monospecific Monoclonal Antibodies [PDF]

, 2019
Cytotoxic NK/CD8+ T cells interact with MHC-I ligands on tumor cells through either activating or inhibiting receptors. One of the inhibitory receptors is CD94/NKG2A.

Selective Targeting of Immune Checkpoints HLA‐G and CD47 Using Novel Dual Signaling Protein DSP216 Promotes Innate Anticancer Immunity

Advanced Science, EarlyView.
The inhibitory immune checkpoints HLA‐G and CD47 are expressed on certain tumor types and inhibit immune cells in the tumor microenvironment. DSP216 binds specifically to cancer cells expressing both HLA‐G and CD47, and blocks their inhibitory signaling.

The human cytomegalovirus-encoded pUS28 antagonizes CD4+ T cell recognition by targeting CIITA

eLife
Human cytomegalovirus (HCMV) is a relevant pathogen, especially for individuals with impaired immunity. Harnessing potent immune antagonists, HCMV circumvents sterile immunity. Given that HCMV prevents the upregulation of human leukocyte antigen (HLA)-DP

The HLA-E Gene encodes two differentially regulated Transcripts and a Cell Surface Protein [PDF]

, 1992
An HLA-E-specific oligonucleotide probe was used to study the expressioonf HLA-E. This probed etects two HLA-E transcripts, 1.8 and 2.7 kb in size, which are present in varying ratios in allt issues and cell lines investigated.

Cationic mRNA Lipid Nanoparticles for Ex Vivo NanoCAR‐T Cell Engineering

Advanced Science, EarlyView.
This study compares charge‑neutral and cationic lipidnanoparticles (LNPs) for ex vivo mRNA delivery to T cells, revealing distinctdependencies on medium composition and T cell activation. Where conventional LNPs benefit from ApoE‐dependent T cell targeting, cationic DOTAP‑modified LNPs mediate unspecific charge‑dependent transfection.

LYMPHOCYTE SUBSETS, IMMUNOGLOBINS AND HUMAN LEUCOCYTE ANTIGENS OF 1-ST CLASS IN PATIENTS WITH ENDOMETRIOSIS

Acta Biomedica Scientifica, 2012
We examined lymphocyte subsets, levels of A, M, G immunoglobulins and Human leucocyte antigens of I-st class (A, B) in 90 patients with endometriosis.
