Based on the results of this study, it can be suggested that FGG performed around DIs lacking KT is a reliable method, leading to significant improvements in clinical and inflammatory parameters. Further long-term studies including more DIs are needed to clarify the role of KT on maintenance of DIs.

Biallelic mutations in the genes encoding CD27 or its ligand CD70 underlie inborn errors of immunity characterized predominantly by EBV-associated immune dysregulation, such as chronic viremia, severe infectious mononucleosis, hemophagocytic lymphohistiocytosis (HLH), lymphoproliferation and malignancy. A comprehensive understanding of the natural history, immune characteristics and transplant outcomes has remained elusive. Here, in a multi-institutional global collaboration, we collected clinical information of 49 patients from 29 families (CD27 n=33, CD70 n=16), including 24 previously unreported individuals and identified a total of 16 distinct mutations in CD27, and 8 in CD70, respectively. The majority (90%) of patients were EBV+ at diagnosis, but only ~30% presented with infectious mononucleosis. Lymphoproliferation and lymphoma were the main clinical manifestations (70% and 43%, respectively), and 9 of the CD27-deficient patients developed HLH. Twenty-one (43%) patients developed autoinflammatory features including uveitis, arthritis and periodic fever. Detailed immunological characterization revealed aberrant generation of memory B and T cells, including a paucity of EBV-specific T cells, and impaired effector function of CD8+ T cells, thereby providing mechanistic insight into cellular defects underpinning the clinical features of disrupted CD27/CD70 signaling. Nineteen patients underwent allogeneic hematopoietic stem cell transplantation (HSCT) prior to adulthood predominantly because of lymphoma, with 95% survival without disease recurrence. Our data highlight the marked predisposition to lymphoma of both CD27- and CD70-deficient patients. The excellent outcome after HSCT supports the timely implementation of this treatment modality particularly in patients presenting with malignant transformation to lymphoma.

The NK cell targeting strategy has not yet been approved for lung cancer treatment. More clinical studies focusing on the role of NK cells in lung cancer pathogenesis are warranted to develop novel NK cell-based therapeutic approaches for the treatment of lung cancer.

Statins possess a wide variety of pleiotropic properties that are independent of their lipid-lowering abilities such as attenuating inflammation, oxidative stress, coagulation, platelet aggregation and stimulating bone formation. The aim of the study is to evaluate the effect of statins on clinical periodontal parameters and gingival crevicular fluid (GCF) levels of IL-1β, IL-10, and myeloperoxidase (MPO) in inflammatory periodontal diseases. Seventy-nine subjects with hyperlipidemia and 48 systemically healthy controls (C) were included. Hyperlipidemic patients were either given a diet (HD) or prescribed statin (HS). Patients were classified into three subgroups as those who were periodontally healthy (h), who had gingivitis (g), or who had chronic periodontitis (p). Blood samples were collected for the measurement of lipid profiles. Plaque index (PI), gingival index (GI), probing pocket depth (PD), clinical attachment level (CAL), and percentage of bleeding on probing (BOP) were recorded. Gingival crevicular fluid levels of IL-1β, IL-10, and MPO were measured in order to determine the anti-inflammatory and antioxidant effects of statins. Probing depth values of the HSp group were significantly lower than those of the Cp group. Percentage of BOP of the HSg group was significantly lower than those of the HDg and Cg groups. While the IL-1β level of the HSp group was significantly lower than that of the HDp group, IL-10 levels of the HSg group were significantly higher than those of the HDg group. MPO levels were significantly lower in the HSg group when compared to those in the HDg and Cg groups. Statin use decreased the IL-1β and MPO levels and enhanced IL-10 in GCF. It can be suggested that statins may attenuate periodontal inflammation and progression of periodontal inflammation.
