Lrig1-expression confers suppressive function to CD4+ cells and is essential for averting autoimmunity via the Smad2/3/Foxp3 axis

Nature Communications, 2023
Regulatory T cells (Treg) are CD4+ T cells with immune-suppressive function, which is defined by Foxp3 expression. However, the molecular determinants defining the suppressive population of T cells have yet to be discovered.

Age-Related Gene Alteration in Naïve and Memory T cells Using Precise Age-Tracking Model

Frontiers in Cell and Developmental Biology, 2021
In aged individuals, age-related changes in immune cells, especially T cell deficiency, are associated with an increased incidence of infection, tumor, and autoimmune disease, as well as an impaired response to vaccination.

Interplay between SMAD2 and STAT5A is a critical determinant of IL-17A/IL-17F differential expression

Molecular Biomedicine, 2021
Interleukins (IL)-17A and F are critical cytokines in anti-microbial immunity but also contribute to auto-immune pathologies. Recent evidence suggests that they may be differentially produced by T-helper (Th) cells, but the underlying mechanisms remain ...

Determination of the level of CD4CD69 T cells in hemodialysis patients

Journal of Medicine in Scientific Research, 2022
Introduction The CD4 helper T cell is responsible for humoral, cellular immunity, and inflammation. CD69 may be a sensitive marker indicating that the CD4 T cell is activated.

Deciphering the combinatorial landscape of immunity

eLife, 2020
From cellular activation to drug combinations, immunological responses are shaped by the action of multiple stimuli. Synergistic and antagonistic interactions between stimuli play major roles in shaping immune processes.

Innate-like NKp30+CD8+ T cells armed with TCR/CAR target tumor heterogeneity

OncoImmunology, 2021
Intratumoral heterogeneity is frequently associated with tumor immune escape, with MHC-class I and antigen expression loss rendering tumor cells invisible to T cell killing, representing a major challenge for the design of successful adoptive transfer ...

Multiple steady states and the form of response functions to antigen in a model for the initiation of T-cell activation [PDF]

Royal Society Open Science, 2017
The aim of this paper is to study the qualitative behaviour predicted by a mathematical model for the initial stage of T-cell activation. The state variables in the model are the concentrations of phosphorylation states of the T-cell receptor (TCR ...

Insights into tertiary lymphoid structures in the solid tumor microenvironment: anti-tumor mechanism, functional regulation, and immunotherapeutic strategies

Cancer Biology & Medicine, 2021
Tertiary lymphoid structures (TLSs) are ectopic immune cell aggregations that develop in peripheral tissues in response to a wide range of chronic inflammatory conditions, including infection, autoimmune disease, and cancer. In the tumor microenvironment

Cells, Cells, and More Cells

Survey of Ophthalmology, 2007
A 64-year-old woman presented with bilateral optic nerve swelling, vitreous cells, and cerebrospinal fluid monocytic pleocytosis. A chest radiograph and computed tomography demonstrated a lesion in the left lung, which histologically was confirmed to be a small-cell lung carcinoma.
