Controversies concerning thymus-derived regulatory T cells: fundamental issues and a new perspective [PDF]

open access: yes, 2015
Thymus-derived regulatory T cells (Tregs) are considered to be a distinct T-cell lineage that is genetically programmed and specialised for immunosuppression.

T cell epitope immunotherapy induces a CD4+ T cell population with regulatory activity. [PDF]

open access: yesPLoS Medicine, 2005
BACKGROUND: Synthetic peptides, representing CD4(+) T cell epitopes, derived from the primary sequence of allergen molecules have been used to down-regulate allergic inflammation in sensitised individuals. Treatment of allergic diseases with peptides may

Destabilizing the autoinhibitory conformation of Zap70 induces up-regulation of inhibitory receptors and T cell unresponsiveness. [PDF]

open access: yes, 2017
Zap70 plays a critical role in normal T cell development and T cell function. However, little is known about how perturbation of allosteric autoinhibitory mechanisms in Zap70 impacts T cell biology.

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

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

Imaging regulatory T cell dynamics and CTLA4-mediated suppression of T cell priming [PDF]

open access: yes, 2015
Foxp3(+) regulatory T cells (Tregs) maintain immune homoeostasis through mechanisms that remain incompletely defined. Here by two-photon (2P) imaging, we examine the cellular dynamics of endogenous Tregs.

Tr1-like T cells- an enigmatic regulatory T cell lineage

open access: yesFrontiers in Immunology, 2016
The immune system evolved to respond to foreign invaders and prevent autoimmunity to self-antigens. Several types of regulatory T cells facilitate the latter process.

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 ...

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.

Oestrogen, an evolutionary conserved regulator of T cell differentiation and immune tolerance in jawed vertebrates? [PDF]

open access: yes, 2018
In teleosts, as in mammals, the immune system is tightly regulated by sexual steroid hormones, such as oestrogens. We investigated the effects of 17β-oestradiol on the expression of several genes related to T cell development and resulting T cell ...
