Genomic and functional characterization of human T cell responses to co-stimulation with an agonistic anti-CD27 mAb, 1F5 (Varlilumab)

ABSTRACT: CD27, a member of the tumor necrosis factor receptor super family (TNFRSF7), is constitutively expressed on the majority of mature T cells, memory B cells, and a portion of NK cells. Here we report on the 1F5-induced immune modulation of isolated human T cells. In vitro activation of peripheral blood-derived T cells from different healthy volunteers with mAb 1F5 showed that crosslinking of CD27 in the presence of CD3 stimulation (OKT3 mAb) was essential to elicit proliferation and broad spectrum of cytokine release. Analysis of this response on a multiplex cytokine array system revealed a Th1-biased cytokine profile (IFN-gamma, IL-2 and TNF-alpha). Transcriptional profiling by microarray RNA hybridization is underway to map specific and global gene expression changes following 1F5 modulation of T cells.

Expression data from T-cell Acute Lymphoblastic Leukemia (T-ALL) patient-derived xenograft treated with anti-CD3 mAb

Project description:T-cell acute lymphoblastic leukemia is a hematological malignancy treated by chemotherapy, with a poor prognosis. We have demonstrated that activation of the T cell receptor (TCR) by anti-CD3 antibodies has a potent anti-leukemic effect in patient-derived xenograft models (PDX) of T-ALL. Therefore, with this experiment, we aim to identify the molecular mechanisms underlying the anti-leukemic properties of the OKT3 anti-CD3 mAb in T-ALL PDX.

Expression data from T-cell Acute Lymphoblastic Leukemia (T-ALL) patient-derived xenograft treated with anti-CD3 mAbs.

Project description:T-cell acute lymphoblastic leukemia is an aggressive hematological malignancy treated with chemotherapy and has a poor prognosis. In previous studies, we demonstrated that T cell receptor (TCR)-induced negative selection is highly effective in combating T-ALL in mouse models. Moreover, targeting the TCR of diagnostic T-ALL-derived PDX with anti-hCD3 (aCD3) mAb OKT3 or the clinically relevant aCD3 mAb Teplizumab resulted in leukemic cell death, regression of leukemia, and improved host survival. The objective of the present experiment is to uncover the molecular mechanisms responsible for the anti-leukemic properties of the anti-CD3 mAbs OKT3 and Teplizumab in a T-ALL PDX model. We compare the transcriptomic profiles of FACS-sorted T-ALL cells extracted from T-ALL patient-derived xenograft (PDX) treated for 6h with isotype control antibody IgG2a or OKT3 mAb or Teplizumab mAb.

CD27 costimulation modulates naïve T cell activation through TRAF2/SHP-1 and induces memory-associated gene regulatory networks.

Project description:Engagement of CD27 during naïve CD8+ T (TN) cell activation is critical for T cell memory generation through poorly understood mechanisms. To examine the effects of CD27 signaling during TN cell activation we designed a synthetic trimeric CD70 ligand. In conjunction with T cell receptor (TCR) stimulation, ligation of CD27 resulted in immediate receptor internalization, recruitment of TRAF2/SHP-1, and modulation of Lck and ERK/AKT signaling in cells receiving concurrent CD28 costimulation. Independent of this modulatory effect on CD28 costimulated T cells, CD27 signaling enhanced ATF2, FOXO1, and FOXP1 transcription factor circuits, which induced T cell memory rather than the effector associated gene programs observed with CD28 costimulation alone. CD27-costimulated T cells engineered with a chimeric antigen receptor (CAR) exhibited improved tumor control. CD27 signaling during TN cell activation modulates activation strength and directs memory T cell properties that may benefit therapeutic T cells engineered with CARs or T cell receptors.

Chronic CD27-CD70 costimulation promotes type 1-specific polarization of effector Tregs

Project description:Most T lymphocytes, including regulatory T cells, express the CD27 costimulatory receptor in steady state conditions. There is evidence that CD27 engagement on conventional T lymphocytes favors the development of Th1 and cytotoxic responses in mice and humans, but the impact on the regulatory lineage is unknown. In this report, we examined the effect of constitutive CD27 engagement on both regulatory and conventional CD4+ T cells in vivo, in the absence of intentional antigenic stimulation. Our data show that both T cell subsets convert into type 1 effectors, characterized by cell activation, cytokine production, response to IFN-and CXCR3-dependent migration to inflammatory sites. Our data highlight the role of the transcription factor Eomes in this process. We conclude that CD27 may regulate the development of Th1 immunity in peripheral tissues as well as the subsequent switch of the effector response into long-term memory.

RNA sequencing analysis of ex vivo expanded CD27+CD70- and CD27-CD70+ human regulatory T cells

Project description:Our study shows that after extended stimulation of human CD4+CD25+CD127- Tregs in vitro, a stable cell subset that downregulates CD27 and upregulates CD70 develops. Expanded CD27+CD70- Tregs display a gene profile which closely relates to the previously described “Treg gene signature”, whereas CD27-CD70+ Tregs express some genes associated with Treg gene signature and some genes overexpressed in conventional T cells.

Comparison of mouse NK cell subsets defined by CD27 and CD11b expression

Project description:Previous reports have defined three subsets of mouse NK cells on the basis of the expression of CD27 and CD11b. The developmental relationship between these subsets was unclear. To address this issue, we evaluated the overall proximity between mouse NK cell subsets defined by CD27 and CD11b expression using pangenomic gene expression profiling. The results suggest that CD27+CD11b-, CD27+CD11b+ and CD27-CD11b+ correspond to three different intermediates stages of NK cell development.

Transcriptional profiles of CD27 negative and positive MAIT cells from PBMC of diabetic obese patients

Project description:Our previous observation found CD27 negative MAIT cell subset is associated with T2D progression in overweight/obese patients. To identify the difference of functional properties between CD27 negative and positive MAIT subsets under obesity related T2D condition, we isolated circulating CD27+ or CD27- CD3+ CD161+ TCR Va7.2+ MAIT cells from PBMC of three diabetic obese patients and performed bulk RNA-seq based on Smart-seq2 protocol. By the comparison of CD27- and CD27+ MAIT cells, we found CD27- MAIT cell exhibit an increased mitochondrial mass and decreased response to bacterium transcriptional pattern compared to CD27+ MAIT cells in diabetic obese patients, indicating the imbalanced cell-bacteria interaction might contribute to T2D progression in overiweight/obese people.

CD27 marks embryonic hematopoietic stem cells

Project description:Cell surface markers of adult hematopoietic stem cells (HSCs) are well established, but fewer markers are available for embryonic HSCs and their immediate precursors (pre-HSCs) in the major arteries. We performed RNA-Seq on a population of cells from the major arteries of embryonic day 11.5 mouse embryos enriched for lymphoid progenitors, pre-HSCs, and HSCs. We determined that Tnfrsf7, encoding CD27, a member of the tumor necrosis factor receptor superfamily, is upregulated in this population. CD27 is found on ~5% of hematopoietic cluster cells in the major arteries, and enriches for progenitors with lymphoid potential, embryonic HSCs, and Type II pre-HSCs (CD144+CD45+), and fetal liver HSCs. It does not, however, enrich for yolk sac derived erythro-myeloid progenitors. Collectively, those data show that CD27 is a new cell surface marker of embryonic HSCs and Type II pre-HSCs.
