Identifying a Murine Xenograft Model Relevant to Light-Chain Specific Approaches to Human Ig Light-Chain Diseases
CONCLUSIONS: The ALMC-1, RPMI 8226 and H929 IP models did not meet the criteria we required in order to effectively test specific interventions on circulating LC (Table 1). The NSG JJN3 IP model had a short latency period for LC, β2M and FLUX measurements, and had significant correlations among these measurements. The NSG JJN3 model met our criteria. We are currently evaluating soluble BCMA levels in this model also, These measurements will allow investigators to distinguish the impact of interventions on LC specifically, independent of tumor cells. We have used this model successfully to test an RNAi approach to redu...

NF κB and Kidney Injury
Conclusion As a critical regulator of inflammation and cell survival, the NFκB pathway is a promising target for diagnosing and treating kidney diseases. For modulation of the NFκB pathway in the clinic, a number of molecules can effectively inhibit NFκB signaling by targeting the receptors, associated adaptors, IKKs, IκBs and transcriptional regulators (144). There is further clinical evidence on small-molecule inhibitors of IKKα and NIK from recent trials on anti-cancer therapies (145). These clinical trials showed that the cancer-selective pharmacodynamic response of DTP3, the co...

Engineered Extracellular Vesicles From Human Periodontal-Ligament Stem Cells Increase VEGF/VEGFR2 Expression During Bone Regeneration
Conclusion In conclusion our results evidenced that 3D-COL/hPDLSCs/PEI-EVs may be an efficacious strategy to induce bone regeneration and vascularization of bone defects, thanks to its capacity to increase the levels of VEGF. Ethics Statement The study was performed in accordance with the guidelines of the Helsinki Declaration (2013). The written approval for the human periodontal ligament collection performed in this study has been obtained from the Medical Ethics Committee at the Medical School, “G. d’Annunzio” University of Chieti–Pescara, Chieti, Italy (n°266/17.04.14, Principal in...

Human CAR NK Cells: A New Non-viral Method Allowing High Efficient Transfection and Strong Tumor Cell Killing
In conclusion, the method of NK cell transfection described in our present study is highly efficient, does not require expensive dedicated structures necessary for viral transduction and avoids possible risks associated with the use of viral vectors. Importantly, it may be applied to NK cells or NK-92 cell line, greatly improving their anti-tumor activity and providing a new NK cell-based platform for new protocols of adoptive immuno-therapy of cancer. Ethics Statement The Ethical Committee of IRCCS Bambino Gesù Pediatric Hospital approved the study (825/2014). Author Contributions TI designed and performed res...
