CAR-T Panel Functional Annotations

This panel includes 780 genes covering T-cell biology and the pathways and processes important to T-Cell research and development, especially signaling pathways influencing T-cell differentiation and activity, phenotypic and metabolic switches, T-cell subsets associated with differentiation and activation state, T-Cell Receptor diversity and immune cell profiling.

Essential CAR-T Biology
DescriptionPathways and Processes
PhenotypeMultiple subtypes of T-cells and the phenotypic changes that accompany them can be distinguished via the cytokines and pathways that maintain, promote, and modulate their activity.Notch, Wnt signaling, Tfh, TGF-beta, Th1, Th17, Th2, Th9, Treg, Innate-like T-cells, Vitamin A (RA) Signaling
Cell TypesOther cell types can contaminate the population of active CAR-T cells. Similarly, measurement of B-cell populations may aid in assessment of whole blood post-infusion measurement of tumor burden in B-cell lymphomas.Immune cell profiling
TCR DiversityThe TCR diversity of CAR-T cells can provide information on the number of clones present after leukapheresis, manufacturing, and infusion.TCR Content
ActivationT-cell activation is primarily mediated by antigens presented to the TCR complex and modulated by costimulatory molecules. Downstream of the TCR, multiple pathways induce transcriptional changes that lead to the production of chemokines and cytokines. Cell surface receptors signal a change in phenotype.Chemokine Signaling, Costimulatory Molecules, Interleukin Signaling, TCR signaling, JAK-STAT, MAPK and PI3K Signaling, Myc targets, NFAT, Antigen processing & presentation, T-cell activation markers
MetabolismFundamental changes in T-cell metabolism are induced upon activation to enable rapid cell division and thus expansion of relevant clones. These changes can be observed across basic metabolic pathways, including carbohydrate and fatty acid metabolism.Glycolysis, Mitochondrial biogenesis, Fatty Acid Metabolism
Glutamine metabolism, Circadian Clock, One-carbon metabolism, Oxidative phosphorylation, mTOR, Cell Cycle, Autophagy
PersistenceOngoing presence of a T-cell and cytotoxic T-cell population can be measured by via cell type profiling. By measuring molecules involved in T-cell migration we can assess the ability of T-cells to home in on their target antigens.T-cell migration, T-cell cell type profiling
ExhaustionT-cell exhaustion can be induced by costimulatory molecules, other cell-cell interactions, and cell death via apoptosis.T-cell exhaustion markers, Apoptosis, Interactions with Non-Lymphoid Cells, Costimulatory Molecules
ToxicityToxicity is correlated with certain cytokine and chemokine profiles. These signals can induce a pro-inflammatory environment in various tissues and lead to off-target toxicities of CAR-T treatment.NK cell cytotoxicity, NKT Receptors, NF-kB, Type I interferon signaling
Type II interferon signaling, Interleukin signaling, Chemokine signaling

Immune Cell Profiling and TCR Diversity Features

Genes included in the CAR-T Characterization Panel provide unique cell profiling and TCR diversity data to measure the relative abundance of immune cell types1 and shifts in TCR populations2 . The tables below summarize the cell type and TCR diversity content in the panel, as qualified through biostatistical approaches and selected literature in the field of immunology.

Cell Type
DescriptionPanel Genes
# Genes
B CellsB cells are the primary mediators of the humoral immune response, bearing antigen-specific B cell receptors and producing antibodies that can enable the immune system to respond to a broad variety of antigens. B cells can also function as MHC class II antigen presenting cells to stimulate T cell immunity.BLK, CD19, CD20, TNFRSF179
T CellsT-cells mediate cell-based immunity by recognizing primarily peptide antigens displayed on MHC class I or class II and either producing cytokines or directly killing the presenting cell.CD3D, CD3E, CD3G, CD6, SH2D1A6
TH1CD4+ T cell subset that produces IL2 and Interferon-gamma to promote cellular immunity by acting on CD8+ T Cells, NK Cells and Macrophages.TBX211
Regulatory T Cells (Tregs)CD4+ T Cells that suppress effector B and T Cells and play a central role in suppression of the immune response and tolerance to self-antigens.FOXP31
CD8+ T CellsA subset of T cells that are capable of binding cognate-antigen expressing cells via class I MHC and directly lysing them via perforin and granzymes.CD8A, CD8B2
Exhausted CD8+ T CellsT-cells overstimulated by antigen can develop an "exhausted" phenotype, in which they are no longer effective in targeting antigen-bearing cells.CD244, EOMES, CD2234
Cytotoxic CellsAll cells capable of cytotoxic activity, which can include T, NKT, and NK-cells.CTSW, GNLY, GZMA, GZMB, GZMH, CD161, CD94, KLRK1, PRF110
Dendritic CellsProfessional antigen presenting cells that internalize, process, and present antigens to lymphocytes via MHC class I and class II along with costimulatory signals to initiate cellular immune responses.CCL13, CD209, HSD11B13
MacrophagesPluripotent cells with critical roles in initiating innate and adaptive immune responses, phagocytosing abnormal cells, and regulating wound healing and tissue repair.CD163, CD68, CD844
Mast CellsMast cells release histamine containing granules and other signals in order to promote inflammation and regulate allergic responses.MS4A2, TPSAB14
NeutrophilsNeutrophils are highly abundant cells that respond early to sites of infection or inflammation, phagocytose cellular debris, and promote downstream immunity.CSF3R, CD16, S100A126
Natural Killer (NK) CellsCytotoxic cells of the innate immune system that are a significant source of interferon-gamma and are capable of directly killing targeted cells via detection of a loss in MHC surface expression.NKP46, XCL22
NK CD56dim cellsThe amount of CD56 present on an NK cell is indicative of its age and differentiation state; CD56 dim cells are mature NK cells, more commonly found in peripheral blood than secondary lymphoid tissues, and have the greatest cytolytic activity.IL21R, KIR2DL3, KIR3DL1, KIR3DL23
