Tolerance induction in memory CD4 T cells requires two rounds of antigen-specific activation [PDF]

, 2014
Autoimmune diseases are driven by immune cells that recognize self-tissues. A major goal for treatment strategies for autoimmune diseases is to turn off or tolerize self-reactive immune cells such as CD4 T cells that coordinate tissue damage in many ...

IL-4-secreting CD4+ T cells are crucial to the development of CD8+ T-cell responses against malaria liver stages.

, 2002
CD4+ T cells are crucial to the development of CD8+ T cell responses against hepatocytes infected with malaria parasites. In the absence of CD4+ T cells, CD8+ T cells initiate a seemingly normal differentiation and proliferation during the first few days

Targeting self- and foreign antigens to dendritic cells via DC-ASGPR generates IL-10-producing suppressive CD4+ T cells [PDF]

, 2012
Dendritic cells (DCs) can initiate and shape host immune responses toward either immunity or tolerance by their effects on antigen-specific CD4(+) T cells.

Changes in Reactivity In Vitro of CD4+CD25+ and CD4+CD25− T Cell Subsets in Transplant Tolerance

Frontiers in Immunology, 2017
Transplant tolerance induced in adult animals is mediated by alloantigen-specific CD4+CD25+ T cells, yet in many models, proliferation of CD4+ T cells from hosts tolerant to specific-alloantigen in vitro is not impaired.

Mycobacterium tuberculosis-Specific IL-21+IFN-γ+CD4+ T Cells Are Regulated by IL-12. [PDF]

PLoS ONE, 2016
In the current study of Mycobacterium tuberculosis (MTB)-specific T and B cells, we found that MTB-specific peptides from early secreted antigenic target-6 (ESAT-6) and culture filtrate protein-10 (CFP-10) induced the expression of IL-21 predominantly in

Adenovirus vector-specific T cells demonstrate a unique memory phenotype with high proliferative potential and coexpression of CCR5 and integrin α\(_4\)β\(_7\) [PDF]

, 2009
Background: The Step Study was a randomized trial to reduce HIV infection through vaccination with an adenovirus type 5-based gag/pol/nef construct; analysis following early cessation of the trial revealed an excess of HIV seroconversion in Ad5 ...

Killing of Latently HIV-Infected CD4 T Cells by Autologous CD8 T Cells Is Modulated by Nef

Frontiers in Immunology, 2018
The role of HIV-specific CD8 T cell activity in the course of HIV infection and the way it affects the virus that resides in the latent reservoir resting memory cells is debated.

Absence of ZAP-70 prevents signaling through the antigen receptor on peripheral blood T cells but not on thymocytes. [PDF]

, 1995
Recently, a severe combined immunodeficiency syndrome with a deficiency of CD8+ peripheral T cells and a TCR signal transduction defect in peripheral CD4+ T cells was associated with mutations in ZAP-70.

Modulation of phenotype and function of human CD4+CD25+ T regulatory lymphocytes mediated by cAMP elevating agents

Frontiers in Immunology, 2016
We have shown that Cholera Toxin (CT) and other cyclic AMP (cAMP) elevating agents induce up-regulation of the inhibitory molecule CTLA-4 in human resting CD4+ T lymphocytes, which following the treatment acquired suppressive functions. In this study, we

LFA-1/ICAM-1 Interactions Between CD8⁺ and CD4⁺ T Cells Promote CD4⁺ Th1-Dominant Differentiation and CD8⁺ T Cell Cytotoxicity for Strong Antitumor Immunity After Cryo-Thermal Therapy

Cells
CD4+ T cells have been well-regarded as “helper” cells in activating the cytotoxicity of CD8+ T cells for effective tumor eradication, while few studies have focused on whether CD8+ T cells regulate CD4+ T cells.
