The two novel MHC class II transactivators RFX5 and CIITA both control expression of HLA-DM genes [PDF]
, 2017 MHC-encoded HLA-DMA and-DMB molecules are atypical MHC chains that play an essential role in antigen presentation by MHC class II molecules. They resemble both MHC class I and II molecules but are not expressed at the cell surface.

Medicine, 2001 IntroductionPrimary human immunodeficiencies constitute a heterogenous group of inborn errors of the immune system due to a variety of genetic abnormalities. The study of patients with primary immunodeficiency diseases has expanded our understanding of immunity.

Pre‐Encoded IFN‐I Sensitivity Exacerbates Memory T Cell Senescence in Solid Tumors
Advanced Science, EarlyView.Type I interferon (IFN‐I) signaling promotes p21‐dependent cell cycle arrest in senescent tumor‐specific memory T cells, resulting in poor proliferative responses and solid tumor regression during cancer vaccination. Conversely, IFNα/β receptor blockade reinvigorates T cell proliferation to regress solid tumors and is more effective with increasing ...

Advanced Science, EarlyView.This study demonstrates that Mn2⁺–tumor DNA complexes encapsulated in dendritic cell (DC)– derived immunogenic extracellular vesicles (EVDC@Mn‐DNA) act as a DC‐specific cGAS– STING activator. EVDC@Mn‐DNA treatment enhances intratumoral DC activation, improves tumor vascular function, promotes CD8⁺ T cell activity, and suppresses pancreatic tumor growth,

Lymphocyte activation gene 3: a novel therapeutic target in chronic lymphocytic leukemia
Haematologica, 2017 A novel therapeutic approach in cancer, attempting to stimulate host anti-tumor immunity, involves blocking of immune checkpoints. Lymphocyte activation gene 3 (LAG3) is an immune checkpoint receptor expressed on activated/exhausted T cells. When engaged

PD‐1 Inhibits CD4+ TRM‐Mediated cDC1 Mobilization via Suppressing JAML in Human NSCLC
Advanced Science, EarlyView.CD4+ tissue‐resident memory T cells (TRMs) in non‐small cell lung cancer recruit conventional type 1 dendritic cells via XCL1‐XCR1 signaling, orchestrating antitumor immunity. The costimulatory molecule JAML is essential for this process. PD‐1 blockade restores JAML expression and cDC1 mobilization, while JAML agonists synergize with anti‐PD‐1 therapy,

, 2005 Innate and adaptive immunity are connected via antigen processing and presentation (APP), which results in the presentation of antigenic peptides to T cells in the complex with the major histocompatibility (MHC) determinants.

Functional Characterization of a Chicken Major Histocompatibility Complex Class II B Gene Promoter [PDF]
, 1997 A 0.7 kilobase (kb) DNA fragment from the 5\u27 flanking region of a chicken major histocompatibility complex (MHC) class II B gene was cloned into chloramphenicol acetyltransferase (CAT) reporter vectors and was transfected into a chicken macrophage ...

Advanced Science, EarlyView.IL‐15‐engineered stem cell–NK cell complexes, assembled via bioorthogonal chemistry, enable effective lung cancer immunotherapy. Abstract Natural killer (NK) cells represent a powerful immunotherapeutic strategy due to their intrinsic cytotoxicity and ability to target tumor cells independently of antigen presentation.

Major Histocompatibility Complex and Cell Cooperation [PDF]
, 2017 We have studied the role of major histocompatibility antigens on cell cooperation in the immune response of the chicken. In the 1970's, shortly after the initial discoveries in the mouse, we demonstrated that the T cell-B cell interaction is major ...
