Abstract

T cells are used in many cell-based cancer treatments. However, oxidative stress that is induced during various chronic inflammatory conditions, such as cancer, can impair the immune system and have detrimental effects on T cell function. In this study, we have investigated the sensitivity of different human T cell subsets to H2O2-induced oxidative stress. We showed that central memory (CD45RA−CCR7+) and effector memory (CD45RA−CCR7−) T cells are more sensitive to H2O2 as compared with naive (CD45RA+CCR7+) T cells. Furthermore, the study showed that CD8+ effector memory T cells are more sensitive to low levels of H2O2 (5 μM) compared with other types of T cells investigated. H2O2-exposed CD45RO+ T cells showed mitochondrial depolarization prior to caspase 3 activity. Moreover, the pan-caspase inhibitor z-Val-Ala-Asp(OMe)-fluoromethylketone rescued cells from death. These experiments suggest that H2O2-induced cell death of CD45RO+ T cells acts via the mitochondrial pathway and that caspase involvement is needed. This study suggests that oxidative stress in cancer patients can be disadvantageous for T cell-based adoptive cell transfer therapies, since effector memory T cells are the primary phenotype of the cells administered.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • T cells expressing CD57 and KLRG1 are more susceptible to H2O2-induced apoptosis than total lymphocytes and naive phenotype cells in vitro.

    “T cells expressing cell-surface proteins associated with differentiation or “senescence” (e.g., CD57 and KLRG1) are more susceptible to H2O2 induced apoptosis than total lymphocytes (Wang and Lin 2010) and cells of a naïve phenotype (e.g., CD45RA + CCR7+) in vitro (Takahashi et al. 2005).”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
