CD27

a type I transmembrane protein present on mature T cells, medullary thymocytes, and some B cells that is a ligand for CD70 and serves as a member of the nerve growth factor family; expressed in chronic lymphocytic leukemia.

During the year, Roche and Celldex Therapeutics entered into a clinical trial collaboration to evaluate the safety, tolerability and preliminary efficacy of varlilumab, Celldex's CD27 targeting investigational antibody, and MPDL3280A (anti-PDL1), Roche's investigational cancer immunotherapy in a Phase 1/2 study in renal cell carcinoma.
Molecular cloning of human and mouse Fas cDNAs demonstrated that it belongs to the tumor necrosis factor receptor (TNFR) superfamily, which includes the low-affinity nerve growth factor receptor (NGFR), TNFR types I and II, human B-cell antigen CD40, T-cell antigen CD27, and OX40 (Johnson et al.
Based on the expression of CD27 and CD45RA, [gamma][delta] T cells can also be classified into four subsets: naive (CD27+CD45RA+), effector memory (CD27-CD45RA-), central memory (CD27+CD45RA-), and terminally differentiated (CD27-CD45RA+) [21].
In contrast, the noncanonical NF-[kappa]B-activating pathway is activated by B-cell activating factor (BAFF) [35], lymphotoxin [beta] (LT[beta]) [36], CD40 ligand [37], CD27 ligand [38], human T-cell leukemia virus (HTLV) [39], and Epstein-Barr virus (EBV) [40] and it relies on IKK[alpha] and causes activation of NF-[kappa]B2/RelB complexes by inducing the proteolytic processing of the NF-[kappa]B2/p100 precursor.

These cells are characterized by the surface pattern of effector-type or effector-memory T cells (expression of CD45RA, CD11a, CD11b, CLA, [alpha]E[beta]7 and absence of CD27, CD28, CD56, CD62L).
We also performed a nested polymerase chain reaction assay for several genes of interest, including CTLA-4, IL-17A, IL-17B, IL-17C, IL-17D, IL-17E, IL-17F, PLZF, Foxp3, RORyt, CD27, and CD70.
These dynamic changes were also reflected in proportional changes of differentiated CD4 cells that lack CD27 and CCR7, expanding to 72.
