Inactivation of cytidine triphosphate synthase 1 prevents fatal auto-immunity in mice

Nature Communications
De novo synthesis of the pyrimidine, cytidine triphosphate (CTP), is crucial for DNA/RNA metabolism and depends on the CTP synthetases, CTPS1 and −2. Partial CTPS1 deficiency in humans has previously been shown to lead to immunodeficiency, with impaired ...

PathRTM: Real-time prediction of KI-67 and tumor-infiltrated lymphocytes [PDF]

arXiv, 2023
In this paper, we introduce PathRTM, a novel deep neural network detector based on RTMDet, for automated KI-67 proliferation and tumor-infiltrated lymphocyte estimation. KI-67 proliferation and tumor-infiltrated lymphocyte estimation play a crucial role in cancer diagnosis and treatment.

Leveraging current insights on IL‐10‐producing dendritic cells for developing effective immunotherapeutic approaches

FEBS Letters, EarlyView.
In vivo IL‐10 produced by tissue‐resident tolDC is involved in maintaining/inducing tolerance. Depending on the agent used for ex vivo tolDC generation, cells acquire common features but prime T cells towards anergy, FOXP3+ Tregs, or Tr1 cells according to the levels of IL‐10 produced. Ex vivo‐induced tolDC were administered to patients to re‐establish/

THE IMMUNOCOMPETENT CELLS RECEPTORS RESEARCH UNDER EXPERIMENTAL INFLUENZA INFECTION IN VITRO

Инфекция и иммунитет, 2015
Introduction. It is known that interferon is a cytokine and is a substantial part of the immune system necessary for antigenic challenge immune response full expression. Also it is considered that every antigen is an interferon inducer.

FLUORESCENT PROTEINS USING FOR LYMPHOCYTE ACTIVATION ASSAYING [PDF]

Biotechnologia Acta, 2013
Activation of immune cells is a key process in development of the specific immunity. The techniques for monitoring of the movement and the activity of signalling messengers and receptor proteins of lymphocytes in living cells and tissues are the ...

Intracellular Modulation, Extracellular Disposal and Serum Increase of MiR-150 Mark Lymphocyte Activation

PLoS ONE, 2013
Activated lymphocytes release nano-sized vesicles (exosomes) containing microRNAs that can be monitored in the bloodstream. We asked whether elicitation of immune responses is followed by release of lymphocyte-specific microRNAs.

FoxO1 signaling in B cell malignancies and its therapeutic targeting

FEBS Letters, EarlyView.
FoxO1 has context‐specific tumor suppressor or oncogenic character in myeloid and B cell malignancies. This includes tumor‐promoting properties such as stemness maintenance and DNA damage tolerance in acute leukemias, or regulation of cell proliferation and survival, or migration in mature B cell malignancies.

Lymphocyte Redox Imbalance and Reduced Proliferation after a Single Session of High Intensity Interval Exercise. [PDF]

PLoS ONE, 2016
This study investigated whether an acute session of high-intensity interval training (HIIT) is sufficient to alter lymphocyte function and redox status. Sixteen young healthy men underwent a HIIT session on a cycloergometer, consisting of eight bouts of ...

The immunological interface: dendritic cells as key regulators in metabolic dysfunction‐associated steatotic liver disease

FEBS Letters, EarlyView.
Metabolic dysfunction‐associated steatotic liver disease (MASLD) affects nearly one‐third of the global population and poses a significant risk of progression to cirrhosis or liver cancer. Here, we discuss the roles of hepatic dendritic cell subtypes in MASLD, highlighting their distinct contributions to disease initiation and progression, and their ...
