CD8+CD122+ T-cells: a newly emerging regulator with central memory cell phenotypes [PDF]
CD8+CD122+ T-cells have been traditionally described as antigen-specific memory T-cells that respond to previously encountered antigens more quickly and vigorously than their naïve counterparts.

Smad4 represses the generation of memory-precursor effector T cells but is required for the differentiation of central memory T cells. [PDF]
AbstractThe transcriptional regulation underlying the differentiation of CD8+ effector and memory T cells remains elusive. Here, we show that 18-month-old mice lacking the transcription factor Smad4 (homolog 4 of mothers against decapentaplegic, Drosophila), a key intracellular signaling effector for the TGF-β superfamily, in T cells exhibited lower ...

CD4−CD8− (double-negative, DN) T cells are critical orchestrators of the cytokine network associated with the pathogenic inflammatory response in one of the deadliest cardiomyopathies known, Chagas heart disease, which is caused by Trypanosoma cruzi ...

Background Solid tumors pose unique roadblocks to treatment with chimeric antigen receptor (CAR) T cells, including limited T-cell persistence, inefficient tumor infiltration, and an immunosuppressive tumor microenvironment. To date, attempts to overcome

Extensive Replicative Capacity of Human Central Memory T Cells [PDF]
Abstract To characterize the replicative capacity of human central memory (TCM) CD4 T cells, we have developed a defined culture system optimized for the ex vivo expansion of Ag-specific CD4+ T cells. Artificial APCs (aAPCs) consisting of magnetic beads coated with Abs to HLA class II and a costimulatory Ab to CD28 were prepared; peptide-

Concurrent generation of effector and central memory CD8 T cells during vaccinia virus infection. [PDF]
It is generally thought that during the contraction phase of an acute anti-viral T cell reponse, the effector T cells that escape activation-induced cell death eventually differentiate into central memory T cells over the next several weeks.

Central memory CD4+ T cells dominate the normal cerebrospinal fluid [PDF]
To use cerebrospinal fluid (CSF) immune phenotyping as a diagnostic and research tool, we have set out to establish reference values of white blood cell (WBC) subsets in CSF.We assessed the absolute numbers and percentages of WBC subsets by 6-color flow cytometry in paired CSF and blood samples of 84 individuals without neurological disease who ...

Background SARS-CoV-2 pre-existing T-cell immune reactivity can be present in some people. A general perturbation of the main peripheral lymphocyte subsets has been described in severe COVID-19 patients, but very few studies assessed the general memory T-

Cutting Edge: Central Memory CD8 T Cells in Aged Mice Are Virtual Memory Cells [PDF]
Abstract The number of memory phenotype CD8 T cells increases dramatically with aging in both humans and mice. However, the mechanism for this is unknown. The prevailing hypothesis is that memory T cells accumulate with aging as a result of lifelong antigenic stimulation. However, data supporting this supposition are lacking.

A CD45RO+ stem cell memory T cell population intermediate to canonical stem cell memory and central memory T cells in human cancer. [PDF]
Abstract T memory stem cells (Tscm) are integral for effective immunotherapy and antitumor responses, but little is known about Tscm immunobiology in solid human tumors. Here we identify self-renewing and multipotent Tscm tumor-infiltrating lymphocytes (TILs) in human cancer and present a novel Tscm subset which expresses CD45RO, is derived ...
