HIF-2α is indispensable for regulatory T cell function

Nature Communications, 2020
HIF-1α is known to repress regulatory T (Treg) cell function, but less is known about the effect of HIF-2α on these cells. Here, the authors use three different mouse models of inflammatory diseases to show that HIF-2α limits HIF-1α expression and is ...

Protein kinase FAM20C—when subcellular localization matters

FEBS Letters, EarlyView.
FAM20C is a Golgi‐resident kinase that phosphorylates proteins along the entire secretory pathway. The presence of potential FAM20C substrates in the cytoplasm or nucleus raises the question of how the kinase and its substrates encounter each other. Protein kinases achieve signaling specificity through consensus sequence recognition and subcellular ...

Immune checkpoints in circulating and tumor-Infiltrating CD4 + T Cell Subsets in Colorectal cancer patients [PDF]

, 2019
Blockade of inhibitory immune checkpoints (ICs) is a promising therapeutic approach; however, it has shown limited success in some cancers including colorectal cancer (CRC). The tumor microenvironment (TME) is largely responsible for response to therapy,

Activation of the Regulatory T-Cell/Indoleamine 2,3-Dioxygenase Axis Reduces Vascular Inflammation and Atherosclerosis in Hyperlipidemic Mice

Frontiers in Immunology, 2018
T-cell activation is characteristic during the development of atherosclerosis. While overall T-cell responses have been implicated in disease acceleration, regulatory T cells (Tregs) exhibit atheroprotective effects.

Revealing the structure of land plant photosystem II: the journey from negative‐stain EM to cryo‐EM

FEBS Letters, EarlyView.
Advances in cryo‐EM have revealed the detailed structure of Photosystem II, a key protein complex driving photosynthesis. This review traces the journey from early low‐resolution images to high‐resolution models, highlighting how these discoveries deepen our understanding of light harvesting and energy conversion in plants.

Divergent functions for airway epithelial matrix metalloproteinase 7 and retinoic acid in experimental asthma. [PDF]

, 2009
The innate immune response of airway epithelial cells to airborne allergens initiates the development of T cell responses that are central to allergic inflammation.

Notch and NF-kB: Coach and Players of Regulatory T-Cell Resposnse in Cancer [PDF]

, 2018
The Notch signaling pathway plays multiple roles in driving T-cell fate decisions, proliferation, and aberrant growth. NF-kB is a cell-context key player interconnected with Notch signaling either in physiological or in pathological conditions.

Circulating level of regulatory T cells in rheumatic heart disease: An observational study

Indian Heart Journal, 2016
Background: The regulatory T cell (Treg) is essential for prevention of autoimmunity. In a preliminary study, we showed significant deficiency of Tregs (CD4CD25 T cells) in rheumatic heart disease (RHD) patients (an autoimmune disease), but the markers ...

Mapping the evolution of mitochondrial complex I through structural variation

FEBS Letters, EarlyView.
Respiratory complex I (CI) is crucial for bioenergetic metabolism in many prokaryotes and eukaryotes. It is composed of a conserved set of core subunits and additional accessory subunits that vary depending on the organism. Here, we categorize CI subunits from available structures to map the evolution of CI across eukaryotes. Respiratory complex I (CI)

Inflammation in chronic degenerative disorders: A novel CD3+CD56+ subset that regulates CD8+ T cell effector function. [PDF]

, 2017
It has been reported that a growing and heterogeneous group of regulatory cell modulate immune response. In particular, regulation of CD8+ T lymphocyte effector functions is critical for tissue homeostasis and immune tolerance control.
