International Classification:

A61K 49/00

US Classification:

424 92

Abstract:

T cell anergy has been correlated with defective Ras signaling. However, neither a causal relationship nor the mechanism of Ras hypoactivation have been established. Using adenoviral transduction of CAR Tg T cells to enable genetic manipulation in nonproliferating cells, we show that Ras61L restores IL-2 production and MAP kinase signaling in T cells anergized in vitro or in vivo. A gene array screen revealed upregulated diacylglycerol kinase (DGK) in the anergic state, which was confirmed by RT-PCR and Western blot analysis. A DGK inhibitor significantly restored IL-2 production by anergic cells. Our data support a causal role for DGK and defective Ras signaling in T cell anergy.

Abstract:

Embodiments concern methods and composition related to anergic T-cells in patients, such as cancer patients. T cell anergy is a hyporesponsive state induced by TCR engagement in the absence of costimulation (Schwartz, 2003). Anergy induction was initially observed in vitro using chemically-fixed antigen presenting cells (APCs). Subsequently, it was found that anergy could be induced by immobilized anti-CD3 mAb or calcium ionophores (such as ionomycin) in vitro, and by superantigen and soluble antigenic peptide in vivo. Indirect evidence has suggested that T cell dysfunction in the tumor microenvironment and establishment of transplant tolerance is partially due to T cell anergy (Gajewski et al., 2011).
