Correction Ox40 Triggering Blocks Suppression by Regulatory T Cells and Facilitates Tumor Rejection

The authors regret that two of the fl ow cytometry histograms in Fig. 3 C were inadvertently duplicated. The corrected fi gure and its legend appear below. Figure 3. Tumor-infi ltrating T reg cells express functional OX40. (A) TILs were purifi ed from a pool of CT26 tumor nodules, and the CD4 + cell population was analyzed by fl ow cytometry (percentages are shown). As controls, CD4 + T cells w...

Triggering of OX40 (CD134) on CD4(+)CD25+ T cells blocks their inhibitory activity: a novel regulatory role for OX40 and its comparison with GITR.

OX40 (CD134) is a member of the tumor necrosis factor (TNF) receptor family that is transiently expressed on T cells after T-cell receptor (TCR) ligation. Both naive and activated CD4(+)CD25+ regulatory T cells (T reg's) express OX40 but its functional role has not been determined. Since glucocorticoid-induced tumor necrosis factor receptor (GITR), a related TNF receptor family member, influenc...

Concomitant Increase of OX40 and FOXP3 Transcripts in Peripheral Blood of Patients with Breast Cancer

Background: Regulatory T cells (T-regs) have an important role in cancer by suppression of protective antitumor immune responses. Regulatory T cells express the forkhead/winged helix transcription factor (FOXP3) and OX40 molecules which have important regulatory roles in the immune system. Objective: To evaluate FOXP3 and OX40 transcripts in the peripheral blood mononuclear cells of women with ...

PD-1 Blockade and OX40 Triggering Synergistically Protects against Tumor Growth in a Murine Model of Ovarian Cancer

The co-inhibitory receptor Programmed Death-1 (PD-1) curtails immune responses and prevent autoimmunity, however, tumors exploit this pathway to escape from immune destruction. The co-stimulatory receptor OX40 is upregulated on T cells following activation and increases their clonal expansion, survival and cytokine production when engaged. Although antagonistic anti-PD-1 or agonistic anti-OX40 ...
