Immunohistochemical study of uveal melanoma and its cellular microenvironment

Успехи молекулярной онкологии, 2022
Introduction. Uveal melanoma pathogenesis is determined by a number of factors, including the tumor molecular genetics, the organism’s immune response, and other ones.

Epi-drugs in combination with immunotherapy: a new avenue to improve anticancer efficacy [PDF]

, 2017
Immune checkpoint factors, such as programmed cell death protein-1/2 (PD-1, PD-2) or cytotoxic T lymphocyte-associated antigen-4 (CTLA-4) receptors, are targets for monoclonal antibodies (MAbs) developed for cancer immunotherapy.

Cell surface interactome analysis identifies TSPAN4 as a negative regulator of PD‐L1 in melanoma

Molecular Oncology, EarlyView.
Using cell surface proximity biotinylation, we identified tetraspanin TSPAN4 within the PD‐L1 interactome of melanoma cells. TSPAN4 negatively regulates PD‐L1 expression and lateral mobility by limiting its interaction with CMTM6 and promoting PD‐L1 degradation.

T-cell antigen CD28 mediates adhesion with B cells by interacting with activation antigen B7/BB-1.

Proceedings of the National Academy of Sciences, 1990
Studies using monoclonal antibodies (mAbs) have implicated the homodimeric glycoprotein CD28 as an important regulator of human T-cell activation, in part by posttranscriptional control of cytokine mRNA levels. Although the CD28 antigen has functional and structural characteristics of a receptor, a natural ligand for this molecule has not been ...

Immune checkpoint inhibitors in renal cell carcinoma [PDF]

, 2017
The immune system has long been known to play a critical role in the body's defence against cancer, and there have been multiple attempts to harness it for therapeutic gain.

HIV‐1 establishes immediate latency in T cells expressing the viral Nef protein

FEBS Open Bio, EarlyView.
Nef is a viral protein often omitted from HIV‐1 reporter viruses. Consequently, its role in viral latency is unclear. We developed three novel dual reporter HIV‐1 derivatives that express Nef and allow for detection of latent and productive infection. Using these reporters, we show that Nef does not affect the establishment of immediate viral latency ...

Characterization of Antigen-Induced CD4+ T-Cell Senescence in Multiple Sclerosis

Frontiers in Neurology, 2022
Antigen-induced T-cell exhaustion and T-cell senescence are peripheral regulatory mechanisms that control effector T-cell responses. Markers of exhaustion and senescence on T Cells indicate the previous activation by repetitive stimulation with specific ...

The Role of Costimulatory Receptors of the Tumour Necrosis Factor Receptor Family in Atherosclerosis [PDF]

, 2011
Atherosclerosis is a chronic inflammatory disease that is mediated by both the innate and adaptive immune responses. T lymphocytes, that together with B cells are the cellular effectors of the adaptive immune system, are currently endowed with crucial ...

Germanane Quantum Dots Promote Metabolic Reprogramming of Immune Cells Toward Regulatory T Cells and Suppress Inflammation In Vitro and In Vivo

Advanced Functional Materials, EarlyView.
Metabolic changes in immune cells direct the phenotype and function of the host immune system. Smart nanomaterials must target metabolic pathways to direct immune cell fate. This study reports the fabrication and first application of germanane quantum dots (GeHQDs) to modulate inflammation in vitro and in vivo.

mSA2 affinity-enhanced biotin-binding CAR T cells for universal tumor targeting

OncoImmunology, 2018
Chimeric antigen receptor T cells (CAR-Ts) are promising cancer therapeutics. However, since cancer cells can lose the CAR-targeted antigen and avoid destruction, targeting multiple antigens with multiple CARs has been proposed. We illustrate here a less
