Crossresistance to immunotherapy is cell intrinsic, acquired during
Given the parallel existence of different nomenclatures for subsets of specific phenotypes of CD8 + T cells, we clarify below the terms used throughout the paper:. T cell exhaustion. State of T.

The generation of these qualitatively superior CD8 + T cells that mediate viral control underlies the synergy between PD-1 and IL-2. Our results show that the PD-1 + TCF1 + stem-like CD8 + T cells, also referred to as precursors of exhausted CD8 + T cells, are not fate-locked into the exhaustion program and their differentiation trajectory can be changed by IL-2 signals.
CaTCH reveals a strong clonal selection of RAFi/MEKitreated melanoma
T cells recognize foreign antigens using T-cells receptors (TCRs). TCRs recognize foreign epitopes within the context of MHC proteins as a complex, the peptide-MHC complex (pMHC). as opposed to LCMV-Arm that causes acute infection. Rafi Ahmed, at that time a postdoctoral fellow in the Oldstone lab,.
Inhibition of the reactivated MAPK pathway in RAFi resistant RTT
Contributed by Rafi Ahmed, May 17, 2019 (sent for review March 1, 2019; reviewed by Nina Bhardwaj and Stephen C. Jameson) We have recently defined a novel population of PD-1 (programmed cell death 1)+ TCF1 (T cell factor 1)+ virus-specific CD8 T cells that function as resource cells during chronic LCMV infection and pro-

Rafi Ahmed; T cell dysfunction is a characteristic feature of chronic viral infection and cancer. Recent studies in chronic lymphocytic choriomeningitis virus (LCMV) infection have defined a PD-1.
The RTT signaling program predicts immunotherapy response in patients
We compared low-dose sequential inhibitor treatment to low-dose concurrent treatment. For sequential treatment, cells were treated with the initial RAFi or ERKi for 3 days, and then the other inhibitor ([RAFi + ERKi] or [ERKi + RAFi]) was added. In Pa02C cells, RAFi/ERKi resulted in 70% fewer cells than vehicle or either inhibitor alone (Figure.

Chronic viral infections are characterized by a state of CD8 + T-cell dysfunction that is associated with expression of the programmed cell death 1 (PD-1) inhibitory receptor. A better understanding of the mechanisms that regulate CD8 + T-cell responses during chronic infection is required to improve immunotherapies that restore function in exhausted CD8 + T cells.
Phenotype characterization of human melanoma cells resistant to dabrafenib
Anti-PD-L1 antibody treatment is shown to inhibit viral replication in mice synergistically with adoptively transferred CXCR5+ CD8+ T cells. Rafi Ahmed and colleagues show that chronic LCMV.

A major unanswered question is what distinguishes the majority of activated CD8 T cells that die after an acute viral infection from the small fraction (5-10%) that survive to become long-lived memory cells. In this study we show that increased expression of the interleukin 7 receptor alpha-chain (I.

Binding of the PD1-IL2v immunocytokine to PD-1 and IL-2Rβγ on the same cell leads to an alternative differentiation of stem-like CD8+ T cells into better effectors rather than exhausted T.

Determination of cell free RAF inhibition potency for RAFi. Cell free IC 50 s of RAFi were performed at Nanosyn (Sunnyvale, CA) using a cascade MAPK-pathway assay format, measuring the ultimate phosphorylation of a peptide substrate for ERK. Compounds (250 nl of a 100x DMSO stock) were dispensed by an Echo 650 acoustic liquid handler (Beckman.

PD-1+TCF1+ stem-like CD8+ T cells—precursors of exhausted CD8+ T cells—are not fate-locked into the exhaustion program; their differentiation trajectory can be changed by IL-2 signals.
The TME of RTT tumors shows reduced and dysfunctional CD103⁺ DCs a, T
Chronic viral infection induces exhaustion of antigen-specific T cells. Hudson and colleagues define a transitory, effector-like population of CD8+ T cells that are recently generated from stem-like CD8+ T cells in chronic infection. These transitory cells contribute to viral control and are increased in number following PD-1 pathway blockade.

Edited by Rafi Ahmed, Emory University, Atlanta, GA, and approved February 3, 2020 (received for review August 8, 2019) February 24, 2020.. As CD8 T cells primed at the onset of infection become functionally exhausted, thymic function and T-lymphopoiesis is restored, demonstrating an additional role for how T cell exhaustion allows normal.
