CD27 is a co-stimulatory molecule of T cells, and inherited CD27 deficiency is characterized by high susceptibility to EBV infection, though the underlying pathological mechanisms have not yet been identified.

Since homozygosity mapping and exome sequencing did not reveal additional modifying factors, our findings suggest that lack of functional CD27 predisposes towards a combined immunodeficiency associated with potentially fatal EBV-driven hemo-phagocytosis, lymphoproliferation, and lymphoma development.

The observation of defective memory B cells with abnormal cell marker expression and function demonstrates that naive CVID B cells including those expressing IgD(+) CD27(+), in analogy to cord blood and hyper-IgM syndrome B cells, may be responsible for their failure to differentiate into plasma cells and to produce high-affinity antibodies of different isotypes.

Using flow cytometry, we further demonstrated that there was a reduction in B cells (CD19+), switched memory B cells (CD27+IgD-) and T follicular helper (Tfh) cells (both CD4+CXCR5+ and CD4+CXCR5Hi) in a CVID patient with NFKB2/p100Δ19, compared to healthy controls.

While the physiology of the costimulatory systems including OX40-OX40L, CD28/CTLA-4-CD80/86, ICOS-B7RP1 and CD70-CD27 has been relatively well studied in SLE, recent data on the immunopathology of the CD137-CD137 ligand (CD137L) system in murine lupus models and patients with SLE highlight the critical role of this costimulatory system in initiating and perpetuating the diverse clinical and serological phenotypes of SLE.
