Marker descriptions
CD155
CD155 is an adhesion molecule belonging to the Nectin/Nectin-like family that is often overexpressed in tumor cells and involved in many different processes such as cell adhesion, migration and proliferation. It is now referred to as an immune checkpoint protein and interacts with CD96, CD226, and T cell immunoreceptor with immunoglobulin and ITIM domains (TIGIT) on tumor-infiltrating lymphocytes to modulate the immune function in tumor immune microenvironment.
CD27
CD27 also known as TNFRSF7 is a member of the tumor necrosis factor receptor superfamily and plays a key role in T-cell activation by providing a costimulatory signal. Bound to its natural ligand CD70, CD27 signaling enhances T-cell proliferation and differentiation to effector and memory T cells and therefore has potential as an immune modulatory target in cancer treatment.
CD28
The CD28 surface receptor is normally expressed on CD4+ T-cells and some CD8+ T-cells to provide co-stimulatory signals required for T cell activation and survival. Its natural ligands, the B7 molecules, are found on various antigen-presenting cells. CD28 expression increases in activated T-cells. CD28 is the receptor for CD80 (B7.1) and CD86 (B7.2) proteins.
CD40
CD40 receptor and its ligand CD40L (CD154) belong to the TNF:TNFR family. CD40 is expressed on B cells, macrophages and DCs, as well as many nonimmune cells. The CD40–CD40 ligand (CD40L) system is of pivotal importance in the immune response via interactions between T cells and antigen-presenting cells. Recent data suggests that CD40 activation is critical to convert so-called cold tumors to hot ones, thus sensitizing them to checkpoint inhibition.
CD70
The CD27/CD70 costimulatory pathway is part of the TNF receptor/ligand family and regulates cellular activity in subsets of T, B and natural killer cells. CD70 is only transiently expressed on T and B cells following antigen activation and on mature dendritic cells. The interaction of CD70/CD27 is implicated in tumor cell and regulatory T cell survival.
CD73
The membrane bound NT5E (CD73) is an ecto-5′-nucleotidase (NT5E) hydrolyzing extracellular adenosine monophosphate (AMP) into adenosine and inorganic phosphate. NT5E plays a significant role as immune-inhibitory checkpoint molecule. Indeed, infiltration of tumors by NT5E expressing regulatory immune cells such as Tregs results in accumulation of immunosuppressive adenosine that can activate cAMP signaling in T cells expressing the A2A adenosine receptor (ADORA2A).
CD80
CD80 (also known as B7-1) is a costimulatory molecule known for its role in T-cell activation and also in regulating the activity of normal and malignant B cells. CD80 is the ligand for the proteins CD28 (for autoregulation and intercellular association) and CTLA-4 (for attenuation of regulation and cellular disassociation) found on the surface of T-cells. It is currently recognized as one of the most potent costimulatory molecules by which immune cells limit cancer progression.

Due to its broad expression on lymphocytes, TIGIT may prevent tumour antigen release by NK cells, impair T cell priming by DCs or inhibit cancer cell killing by CD8+ T cells. Inhibition of TIGIT may restore anti-tumor T cell activity through competition with its costimulatory receptor, CD226.
CD39
CD39 is a NTPDase (ecto-nucleoside triphosphate diphosphohydrolase) that regulates immune responses balance by hydrolyzing ATP and ADP. It is expressed by B cells, innate cells, regulatory T cells as well as activated CD4 and CD8 T cells, which, in coordination with several other markers such as CD73 can result in local production of adenosine leading to an immunosuppressive environment.

CD38
CD38 also known as cyclic ADP ribose hydrolase is a glycoprotein found on the surface of CD4+, CD8+ T cells, B lymphocytes and natural killer cells. CD38 also functions in cell adhesion, signal transduction and calcium signaling particularly its enzymatic activity which includes the production of adenosine diphosphate ribose (ADPR) or cyclic ADPR (cADPR). The functions of CD38 in the tumor microenvironment ultimately decrease extracellular NAD+, alters calcium signaling cascades, and produce immunosuppressive adenosine.
CD4
CD4 is a member of the immunoglobulin superfamily and is part of the TCR/CD3 complex, binding to MHC class II molecules and participating in signal transduction through recruitment of tyrosine kinase Lck. CD4 expression is used to identify helper T cells of which there are many different subsets including Th1, Th2, Th9, Th17, regulatory T cell, and follicular helper T cell. Each of these contributes to immune function through their unique cytokine profile.

CD22 also known as Siglec-2 is a transmembrane glycoprotein expressed by mature B cells. It inhibits signal transduction by the B cell receptor and its co-receptor CD19 as well as B cell survival, through mechanisms that are both dependent on, and independent of, its ligand-binding activity. Given that CD22 is expressed on the surface of most B-cell leukemias and lymphomas it has therefore been explored as a target for CAR and Ab-based therapies.
CD27
CD27 also known as TNFRSF7 is a member of the tumor necrosis factor receptor superfamily and plays a key role in T-cell activation by providing a costimulatory signal.

Presentation of the antigen by MHC II complex is critical in CD4 activation and development of adaptive immune response. Along with APC’s, B cells and epithelial cells also present the MHC II molecule.
PAX5
Paired box protein Pax-5 (Pax5) are important regulators in early development, and alterations in the expression of their genes are thought to contribute to tumor development. Its expression is detectable as early as the pro–B cell stage and subsequently in all further stages of B cell development until the plasma cell stage are important regulators in early development. They have been implicated in human B cell malignancies, as it is deregulated by chromosomal translocations in a subset of acute lymphoblastic leukemias and non-Hodgkin lymphomas.

BIM expression is correlated with improved tumor survival outcome; and its, up-regulation can restore cancer cells sensitive to targeted therapies.
Ki67
Ki67 is a nuclear marker associated with cellular proliferation. Ki67 is present within the nucleus of cells undergoing division during interphase but is absent in quiescent cells. Ki67 can also be used as a prognostic indicator in certain cancers.
MCL-1
Myeloid leukemia 1 (MCL-1) is an antiapoptotic protein of the BCL-2 family that prevents apoptosis by binding to the pro-apoptotic BCL-2. The abilities of malignant cells to evade cell death likewise depend on individual or multiple pro-survival proteins BCL-2 family members (MCL-1, BCL-2, BCL-XL) that bind to and sequester pro-apoptotic BH3-only activator as well as effector molecules.
CD27
CD27 also known as TNFRSF7 is a member of the tumor necrosis factor receptor superfamily and plays a key role in T-cell activation by providing a costimulatory signal. Bound to its natural ligand CD70, CD27 signaling enhances T-cell proliferation and differentiation to effector and memory T cells and therefore has potential as an immune modulatory target in cancer treatment.
CD3
CD3 is a multimeric protein composed of 4 subunits (γ, δ, ε, ζ), which are part of the T-cell receptor (TCR). Engagement of CD3 induces downstream signaling events that result in T-cell activation. The specificity of the CD3 antigen for T cells and its appearance at all stages of T cell development makes it an ideal T cell marker for both the detection of normal T cells and T cell neoplasms.
CD38
CD38 also known as cyclic ADP ribose hydrolase is a glycoprotein found on the surface of CD4+, CD8+ T cells, B lymphocytes and natural killer cells. CD38 also functions in cell adhesion, signal transduction and calcium signaling particularly its enzymatic activity which includes the production of adenosine diphosphate ribose (ADPR) or cyclic ADPR (cADPR). The functions of CD38 in the tumor microenvironment ultimately decrease extracellular NAD+, alters calcium signaling cascades, and produce immunosuppressive adenosine.
CD4
CD4 is a member of the immunoglobulin superfamily and is part of the TCR/CD3 complex, binding to MHC class II molecules and participating in signal transduction through recruitment of tyrosine kinase Lck. CD4 expression is used to identify helper T cells of which there are many different subsets including Th1, Th2, Th9, Th17, regulatory T cell, and follicular helper T cell. Each of these contributes to immune function through their unique cytokine profile.
CD45RO
CD45RO is expressed on activated and memory T cells, some B cell subsets, activated monocytes/macrophages, and granulocytes. Lack of CD45RO on T cells indicates naive T cell subsets while CD45RO expression indicated previous antigen exposure and defines the memory T cell subset. High density of CD45RO+ T cells in solid tumors is associated with a better prognosis.
CD70
The CD27/CD70 costimulatory pathway is part of the TNF receptor/ligand family and regulates cellular activity in subsets of T, B and natural killer cells. CD70 is only transiently expressed on T and B cells following antigen activation and on mature dendritic cells. The interaction of CD70/CD27 is implicated in tumor cell and regulatory T cell survival.
CD8
CD8 is primarily expressed on cytotoxic T cells, but it can also be expressed on cortical thymocytes, dendritic cells and NK cells. CD8 is a transmembrane glycoprotein that is a co-receptor for the T cell receptor (TCR). CD8 binds MHC Class I to aid in antigen recognition and TCR-mediated activation. CD8 forms dimers of CD8ɑ and CD8β and clone C8/144B recognizes the alpha form of CD8.
FoxP3
FoxP3, or Forkhead Box P3 is a transcription factor important in the development and inhibitory function of regulatory T cells (Tregs). FoxP3 functions by inhibiting cytokine production and T cell effector function, thus playing a crucial role in maintenance of immunological tolerance and control of immune responses against tumors and pathogens.
GrzB
Granzyme B (GrzB) is a serine protease stored in secretory granules of Cytotoxic T lymphocytes (CTLs) and Natural killer (NK) cells. Activated cytotoxic cells release granzyme B which enters the target cells where it can interact with cellular substrates to initiate cell death.
LAG3
Lymphocyte-activation gene 3 (LAG3) is a member of the immunoglobulin superfamily and a CD4 homolog. It is an immune checkpoint receptor protein found on the cell surface of effector T cells and regulatory T cells (Tregs) and functions to control T cell response, activation and growth. Accumulating evidence indicates that LAG3 is an inhibitory coreceptor and plays pivotal roles in autoimmunity, tumor immunity, and anti-infection immunity.
PD-1
Programmed cell death protein 1, also known as PD-1 and CD279, is an inhibitory receptor expressed by all T cells during activation. It regulates T cell effector functions during physiological responses, including acute and chronic infection, cancer, and autoimmunity. When PD-1 is bound to his ligand PD-L1, it prevents T cells from killing target cells including cancer cells.
PD-L1
Programmed cell death ligand 1 (PD-L1) is a type 1 transmembrane protein (B7-H1) that belongs to the B7 ligands family and may be expressed on both, hematopoietic cells (dendritic cells, macrophages, mast cells, T cells and B cells) and non-hematopoietic cells, including endothelial, epithelial and tumor cells. It plays an immunosuppressive role by inhibiting T-cell activity. Overexpression of PD-L1 by cancer cells may enable them to evade the host immune response, conferring a growth advantage to such tumors.
CD20
CD20 is a B cell differentiation antigen expressed in B cell development from early pre-B cell stage to mature B cell stage but lost on differentiation into plasma cells. Its role is in regulating B- cell activation, proliferation and differentiation. Aberrant CD20 expression has been described in mainly B cell tumor types such as Burkitt lymphoma, non-Hodgkin lymphoma, and chronic lymphocytic leukemia (CLL).
CD3
CD3 is a multimeric protein composed of 4 subunits (γ, δ, ε, ζ), which are part of the T-cell receptor (TCR). Engagement of CD3 induces downstream signaling events that result in T-cell activation. The specificity of the CD3 antigen for T cells and its appearance at all stages of T cell development makes it an ideal T cell marker for both the detection of normal T cells and T cell neoplasms.
CD335
CD335, also known as NKp46, belongs to the natural cytotoxicity receptor (NCR) family and it is selectively expressed on NK cells and a subset of NKT cells. It is involved in NK cell triggering of receptors recognizing non-MHC ligands during the process of natural cytotoxicity and tumor cell lysis by NK cells.
CD38
CD38 also known as cyclic ADP ribose hydrolase is a glycoprotein found on the surface of CD4+, CD8+ T cells, B lymphocytes and natural killer cells. CD38 also functions in cell adhesion, signal transduction and calcium signaling particularly its enzymatic activity which includes the production of adenosine diphosphate ribose (ADPR) or cyclic ADPR (cADPR). The functions of CD38 in the tumor microenvironment ultimately decrease extracellular NAD+, alters calcium signaling cascades, and produce immunosuppressive adenosine.

CD45RO is expressed on activated and memory T cells, some B cell subsets, activated monocytes/macrophages, and granulocytes. Lack of CD45RO on T cells indicates naive T cell subsets while CD45RO expression indicated previous antigen exposure and defines the memory T cell subset. High density of CD45RO+ T cells in solid tumors is associated with a better prognosis.
CD56
CD56, also known as neural cell adhesion molecule (NCAM) is a transmembrane glycoprotein often considered a marker of neural lineage commitment due to its discovery site. CD56 expression is most strongly associated with natural killer (NK) cells but it has also been detected on other lymphoid cells, including gamma delta (γδ), T cells and activated CD8+ T cells, as well as dendritic cells.
CD68
CD68 is expressed on human macrophages and other mononuclear phagocytes. CD68 is a heavily glycosylated glycoprotein that is involved in ligand binding and is a member of the scavenger receptor family. CD68 functions in phagocytic activities and macrophage homing. An increased CD68+ macrophage index is associated with metastasis, shorter disease-free interval, poor prognosis, and reduced overall survival in multiple types of cancer.
CD8
CD8 is primarily expressed on cytotoxic T cells, but it can also be expressed on cortical thymocytes, dendritic cells and NK cells. CD8 is a transmembrane glycoprotein that is a co-receptor for the T cell receptor (TCR). CD8 binds MHC Class I to aid in antigen recognition and TCR-mediated activation. CD8 forms dimers of CD8ɑ and CD8β and clone C8/144B recognizes the alpha form of CD8.
BCMA
B-cell maturation antigen (BCMA), also referred to as tumor necrosis factor receptor superfamily member 17 (TNFRSF17) is a member of the tumor necrosis factor receptor superfamily and is expressed by mature B lymphocytes, plays a critical role in regulating B-cell proliferation and survival. Its overexpression and activation are associated with several hematologic malignancies, including multiple myeloma, non-Hodgkin lymphoma, and Hodgkin lymphoma.
CD138
CD138 (syndecan-1) is a canonical plasma cell marker. Its many functions, include wound healing, cell adhesion and endocytosis. Importantly many proteins can bind to CD138, including extracellular matrix components and integrins for adhesion. Altered CD138 expression has been described in various malignant tumor types and poor patient prognosis.
CD19
CD19 is also known as B-Lymphocyte Surface Antigen B4, T-Cell Surface Antigen Leu-12 and CVID3 and is expressed on follicular dendritic cells and B cells. It is critically involved in establishing intrinsic B cell signaling levels by modulating both B cell receptor (BCR)-dependent and independent signaling. It also regulates early lymphomagenesis by stabilizing the expression of the proto-oncogene c-myc.
CD22
CD22 also known as Siglec-2 is a transmembrane glycoprotein expressed by mature B cells. It inhibits signal transduction by the B cell receptor and its co-receptor CD19 as well as B cell survival, through mechanisms that are both dependent on, and independent of, its ligand-binding activity. Given that CD22 is expressed on the surface of most B-cell leukemias and lymphomas it has therefore been explored as a target for CAR and Ab-based therapies.
CD27
CD27 also known as TNFRSF7 is a member of the tumor necrosis factor receptor superfamily and plays a key role in T-cell activation by providing a costimulatory signal. Bound to its natural ligand CD70, CD27 signaling enhances T-cell proliferation and differentiation to effector and memory T cells and therefore has potential as an immune modulatory target in cancer treatment.

CD38 also functions in cell adhesion, signal transduction and calcium signaling particularly its enzymatic activity which includes the production of adenosine diphosphate ribose (ADPR) or cyclic ADPR (cADPR). The functions of CD38 in the tumor microenvironment ultimately decrease extracellular NAD+, alters calcium signaling cascades, and produce immunosuppressive adenosine.
MHC II
Major Histocompability Complex II (MHC II) molecules are heterodimer complex that presents peptide antigen on the surface of the professional antigen presenting cells (APC’s) like macrophages and dendritic cells. Presentation of the antigen by MHC II complex is critical in CD4 activation and development of adaptive immune response. Along with APC’s, B cells and epithelial cells also present the MHC II molecule.
PAX5
Paired box protein Pax-5 (Pax5) are important regulators in early development, and alterations in the expression of their genes are thought to contribute to tumor development. Its expression is detectable as early as the pro–B cell stage and subsequently in all further stages of B cell development until the plasma cell stage are important regulators in early development. They have been implicated in human B cell malignancies, as it is deregulated by chromosomal translocations in a subset of acute lymphoblastic leukemias and non-Hodgkin lymphomas.
