Distinct Features of Canine Non-conventional CD4−CD8α− Double-Negative TCRαβ+ vs. TCRγδ+ T Cells

open access: yesFrontiers in Immunology, 2019
The role of conventional TCRαβ+CD4+ or TCRαβ+CD8α+ single-positive (sp) T lymphocytes in adaptive immunity is well-recognized. However, non-conventional T cells expressing TCRαβ or TCRγδ but lacking CD4 and CD8α expression [i.e., CD4−CD8α− double ...

Poly(2-propylacrylic acid)/poly(lactic-co-glycolic acid) blend microparticles as a targeted antigen delivery system to direct either CD4+ or CD8+ T cell activation. [PDF]

open access: yes, 2017
Poly(lactic-co-glycolic acid) (PLGA) based microparticles (MPs) are widely investigated for their ability to load a range of molecules with high efficiency, including antigenic proteins, and release them in a controlled manner.

The exhausted CD4+CXCR5+ T cells involve the pathogenesis of human tuberculosis disease

open access: yesInternational Journal of Infectious Diseases, 2018
Objectives: CD4+CXCR5+ T cells have previously been established. However, their decreased frequency during tuberculosis (TB) disease is only partially understood.

Blocking Formation of the Stable HIV Reservoir: A New Perspective for HIV-1 Cure

open access: yesFrontiers in Immunology, 2019
Recent studies demonstrate that the stable HIV-1 reservoir in resting CD4+ T cells is mostly formed from viruses circulating when combination antiretroviral therapy (ART) is initiated.

Mdivi-1, a mitochondrial fission inhibitor, modulates T helper cells and suppresses the development of experimental autoimmune encephalomyelitis. [PDF]

open access: yes, 2019
BACKGROUND: Unrestrained activation of Th1 and Th17 cells is associated with the pathogenesis of multiple sclerosis and its animal model, experimental autoimmune encephalomyelitis (EAE).

A screen of Crohn's disease-associated microbial metabolites identifies ascorbate as a novel metabolic inhibitor of activated human T cells. [PDF]

open access: yes, 2019
Microbial metabolites are an emerging class of mediators influencing CD4+ T-cell function. To advance the understanding of direct causal microbial factors contributing to Crohn's disease, we screened 139 predicted Crohn's disease-associated microbial ...

Constitutive CD8 expression allows inefficient maturation of CD4+ helper T cells in class II major histocompatibility complex mutant mice. [PDF]

open access: yes, 1994
Although mature CD4+ T cells bear T cell receptors (TCRs) that recognize class II major histocompatibility complex (MHC) and mature CD8+ T cells bear TCRs that recognize class I MHC, it is possible that the initial commitment of an immature thymocyte to ...

Cyclin kinase inhibitor p21: a mediator of immune tolerance: direct and indirect evidence [PDF]

open access: yes, 2009
*Background:* Uncontrolled proliferation of T-cells is considered a barrier to the induction of transplantation tolerance by T regulatory cells. Therefore, cyclin kinase inhibitor p21, one of the most potent inhibitors of cell proliferation, may exert an

Asymmetric thymocyte death underlies the CD4:CD8 T-cell ratio in the adaptive immune system [PDF]

open access: yes, 2013
It has long been recognized that the T-cell compartment has more CD4 helper than CD8 cytotoxic T cells, and this is most evident looking at T-cell development in the thymus.
