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...

Myeloid Derived Suppressor Cells Interactions With Natural Killer Cells and Pro-angiogenic Activities: Roles in Tumor Progression
Conclusions MDSC are major players in the immunosuppressive scenario in cancer, thanks to their phenotype heterogeneity and critical interaction with several innate immune cells, thus representing a crucial target in oncology. Here we reviewed the interactions of MDSCs with NK cells. The contribution of key cytokines, chemokines and mediators active in this process have been discussed. We also described the contribution of MDSC on angiogenesis directly or indirectly through interactions with NK and immunosuppressive activities. A parallel of the cancer associated to the decidual counterpart of these cells is discussed, a...
