T-cell-T-cell collaboration in allograft responses

Current Opinion in Immunology, 1993
T-cell-T-cell collaboration in allogeneic responses traditionally has been viewed as the requirement for CD4+ T helper cells in the activation of CD8+ cytotoxic T cells. In this regard, the role of the CD4+ T cell is primarily to provide growth factors, such as interleukin-2, on which the CD8+ T cell is dependent.

Replacement of T-Cell Function by a T-Cell Product

Nature New Biology, 1972
WE have recently shown that the immune response to sheep red blood cells (SRBC) in vitro is T-cell dependent, that is, it can be abrogated by pretreatment of the spleen cells with anti-θ serum and complement1. We further reported that reconstitution of the system can be achieved by, among other things, the addition of allogeneic thymocytes2, while ...

T regulatory cells turn on T regulatory cells

Blood, 2009
In this issue of Blood , Miao and colleagues demonstrate that Tregs from a FoxP3 transgenic mouse injected with a normally immunogenic FVIII plasmid not only suppress the response to FVIII but also may “turn on” host Tregs upon adoptive transfer.

Functional T Cell Immunodeficiencies (with T Cells Present)

Annual Review of Immunology, 2013
Severe combined immunodeficiency (SCID) comprises a group of disorders that are fatal owing to genetic defects that abrogate T cell development. Numerous related defects have recently been identified that allow T cell development but that compromise T cell function by affecting proximal or distal steps in intracellular signaling.

T Cell and T-B Cell Immunodeficiency Disorders

Pediatric Clinics of North America, 1977
Very few pure T cell immunodeficiency disorders exist. It is not apparent that the majority of T cell immunodeficiency disorders are also associated with some aberration in the ability to form antibody. This interrelationship is explored in terms of clinical features, laboratory abnormalities, diagnosis, and therapy.

ZEB2 in T-cells and T-ALL

Advances in Biological Regulation, 2019
The identification of the rare but recurrent t(2; 14)(q22; q32) translocation involving the ZEB2 locus in T-cell acute lymphoblastic leukemia, suggested that ZEB2 is an oncogenic driver of this high-risk subtype of leukemia. ZEB2, a zinc finger E-box homeobox binding transcription factor, is a master regulator of cellular plasticity and its expression ...

Impaired autoreactive T cell-induced T cell-T cell interaction in aged mice

Cellular Immunology, 1988
Self-Ia-reactive (autoreactive) L3T4+ T cell clones have been shown earlier to stimulate the proliferation of syngeneic naive L3T4+ T cells and initiate a T cell-T cell (T-T) interaction leading to the generation of immunoregulatory circuits. Since aging has been shown to be associated with a decline of the immune responsiveness, age-related ...

The role of T-cell phenotype and T-cell receptor rearrangement in the diagnosis of T-cell malignancies

Leukemia & Lymphoma, 2015
We read with interest the article by Flammiger et al. [1] on the study of a series of patients with aberrant T-cell phenotype of unclear significance by flow cytometry (FC).

Thymus, T-Cell Differentiation and the T-Cell System

1982
Although it is not possible to say that passage through the thymus is the exclusive pathway that all T-lineage cells must follow, there is ample evidence that the thymus has a profound influence on the development of a fully competent T-cell system (reviewed in Cantor and Weissman, 1976; Stutman, 1978).

Homotypic T-cell/T-cell interaction induces T-cell activation, proliferation, and differentiation

Human Immunology, 2009
Activated CD4 T cells might induce T-cell activation from CD4 resting T cells in the absence of antigen presenting cells through interaction of activation-induced surface molecules (e.g., CD80, CD86, CD70, major histocompatibility complex class II) and their ligands constitutively expressed on resting T cells.
