CD27 is a member of the tumor necrosis factor receptor superfamily.^[5] It is currently of interest to immunologists as a co-stimulatory immune checkpoint molecule, and is the target of an anti-cancer drug in clinical trials.^[6]

Expression

During mouse embryonic development, specific (medium) expression levels of CD27 (in addition to high cKit,^[7][8] medium Gata2,^[9][10][8] and high CD31^[8] expression levels) define the very first adult definitive hematopoietic stem cells generated in the aorta-gonad-mesonephros region.^[8] Furthermore, CD27 is expressed on both naïve and activated effector T cells as well as NK cells and activated B cells.^[5] It is a type I transmembrane protein with cysteine-rich domains, but once T cells have become activated, a soluble form of CD27 can be shed.^[5][6]

Function

The protein encoded by this gene is a member of the TNF-receptor superfamily.^[11] This receptor is required for generation and long-term maintenance of T cell immunity. It binds to ligand CD70, and plays a key role in regulating B-cell activation and immunoglobulin synthesis.^[5]

When CD27 binds CD70, a signaling cascade leads to the differentiation and clonal expansion of T cells.^[11] The cascade also results in improved survival and memory of cytotoxic T cells and increased production of certain cytokines.^[12] This receptor transduces signals that lead to the activation of NF-κB and MAPK8/JNK.^[11] Adaptor proteins TRAF2, TRAF3, and TRAF5 have been shown to mediate the signaling process of this receptor via ubiquitination.^[5][6] CD27-binding protein (SIVA), a proapoptotic protein, can bind to this receptor and is thought to play an important role in the apoptosis induced by this receptor.^[13]

In murine γδ T cells its expression has been correlated with the secretion of IFNγ.^[14]

Clinical significance

As a drug target

Varlilumab is an IgG1 antibody that binds to CD27 and is an experimental cancer treatment.^[6] This agonist antibody stimulates CD27 when it binds.^[6] The drug is in early clinical trials and appears to stimulate T cells and increase production of cytokines such as interferon-gamma.^[6][11]

Interactions

CD27 has been shown to interact with SIVA1,^[15] TRAF2^[16][17] and TRAF3.^[16][17]

Mutations

Some mutations can decrease the expression of CD27. Three such mutations, C53Y, C96Y, and R107C, are located in the cysteine-rich domains of CD27.^[5]
