Memory T cells: strategies for optimizing tumor immunotherapy

Protein & Cell, 2020
Several studies have demonstrated that memory T cells including stem cell memory (Tscm) T cells and central memory (Tcm) T cells show superior persistence and antitumor immunity compared with effector memory T (Tem) cells and effector T (Teff) cells ...

Memory T Cells Discrepancies in COVID-19 Patients

Microorganisms, 2023
The immune response implicated in Coronavirus disease 2019 (COVID-19) pathogenesis remains to be fully understood. The present study aimed to clarify the alterations in CD4+ and CD8+ memory T cells’ compartments in SARS-CoV-2-infected patients, with an ...

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 ...

Age related human T cell subset evolution and senescence

Immunity & Ageing, 2019
T cells are fundamental effector cells against viruses and cancers that can be divided into different subsets based on their long-term immune protection and immediate immune response effects.

C-Myc regulation by costimulatory signals modulates the generation of CD8+ memory T cells during viral infection [PDF]

Open Biology, 2016
The signalling mechanisms of costimulation in the development of memory T cells remain to be clarified. Here, we show that the transcription factor c-Myc in CD8+ T cells is controlled by costimulatory molecules, which modulates the development of memory ...

Effector and memory CD4+ and CD8+ T cells in the chronic infection process.

Folia Histochemica et Cytobiologica, 2009
T cell memory in comparison with B cell memory is not well understood. This review focuses on CD8+ and CD4+ memory T cells. In this article we try to define memory cells and also present models of memory T cells formation. We would also like to delineate

Effector memory differentiation increases detection of replication-competent HIV-l in resting CD4+ T cells from virally suppressed individuals. [PDF]

, 2019
Studies have demonstrated that intensive ART alone is not capable of eradicating HIV-1, as the virus rebounds within a few weeks upon treatment interruption.

Molecular signatures distinguish human central memory from effector memory CD8 T cell subsets [PDF]

, 2005
Memory T cells are heterogeneous in terms of their phenotype and functional properties. We investigated the molecular profiles of human CD8 naive central memory (TCM), effector memory (TEM), and effector memory RA (TEMRA) T cells using gene expression ...
