Memory regulatory T cells in pregnancy

open access: yesFrontiers in Immunology, 2023
Pregnancy requires the process of maternal immune tolerance to semi-allogeneic embryos. In contrast, an overreactive maternal immune system to embryo-specific antigens is likely to result in the rejection of embryos while damaging the invading placenta ...

Tissue regulatory T cells: regulatory chameleons

open access: yesNature Reviews Immunology, 2021
The FOXP3+CD4+ regulatory T (Treg) cells located in non-lymphoid tissues differ in phenotype and function from their lymphoid organ counterparts. Tissue Treg cells have distinct transcriptomes, T cell receptor repertoires and growth and survival factor dependencies that arm them to survive and operate in their home tissue. Their functions extend beyond

Transcript-indexed ATAC-seq for precision immune profiling. [PDF]

open access: yes, 2018
T cells create vast amounts of diversity in the genes that encode their T cell receptors (TCRs), which enables individual clones to recognize specific peptide-major histocompatibility complex (MHC) ligands. Here we combined sequencing of the TCR-encoding

Regulatory T cell memory [PDF]

open access: yesNature Reviews Immunology, 2015
Memory for antigen is a defining feature of adaptive immunity. Antigen-specific lymphocyte populations show an increase in number and function after antigen encounter and more rapidly re-expand upon subsequent antigen exposure. Studies of immune memory have primarily focused on effector B cells and T cells with microbial specificity, using prime ...

Peripheral Blood from Rheumatoid Arthritis Patients Shows Decreased Treg CD25 Expression and Reduced Frequency of Effector Treg Subpopulation

open access: yesCells, 2021
Rheumatoid arthritis (RA) is a common autoimmune disease characterized by immune cell infiltration of the synovium, leading to the loss of cartilage, bone, and joint function.

Notch/Delta signaling constrains reengineering of pro-T cells by PU.1 [PDF]

open access: yes, 2006
PU.1 is essential for early stages of mouse T cell development but antagonizes it if expressed constitutively. Two separable mechanisms are involved: attenuation and diversion. Dysregulated PU.1 expression inhibits pro-T cell survival, proliferation, and

Regulatory T Cells and Parasites [PDF]

open access: yesBioMed Research International, 2011
Human host encounters a wide array of parasites; however, the crucial aspect is the failure of the host immune system to clear these parasites despite antigen recognition. In the recent past, a new immunological concept has emerged, which provides a framework to better understand several aspects of host susceptibility to parasitic infection.

Selective inhibition of T suppressor-cell function by a monosaccharide [PDF]

open access: yes, 1981
Interactions between regulatory T lymphocytes and other cells are assumed to occur at the level of the cell surface. T cells which suppress the generation of specifically effector cells have been described as having antigenic, idiotypic, allotypic and I ...

REGULATORY T–CELLS: ORIGIN AND FUNCTION

open access: yesМедицинская иммунология, 2014
. Over the past decade a population of so–called “regulatory T cells” (Treg cells) has been linked to the prevention of autoimmunity. In this review we discuss the molecular mechanisms of Treg cells development and function including the identification ...

Regulatory T Cells Restrain Pathogenic T Helper Cells during Skin Inflammation

open access: yesCell Reports, 2018
Summary: Psoriasis is a chronic relapsing, remitting interleukin (IL)-23/IL-17-driven skin disease mediated by the interplay of T cells and polymorphonuclear granulocytes. Although preclinical studies have provided insights into the mechanisms of disease
