Current Development of siRNA Bioconjugates: From Research to the Clinic
In this study, it was shown that the main factor determining the nature of the biodistribution of conjugates is their lipophilicity. Conjugates of siRNA with lower lipophilicity; i.e., derivatives of retinoic acid, lithocholic acid, and docosahexanoic acid with greater efficiency than cholesterol conjugates accumulated in the kidneys, bladder, and lungs of the mouse after subcutaneous injection (Biscans et al., 2018). This fact is consistent with previous data that showed that more lipophilic conjugates bind more efficiently to serum components, and thus are not excreted by the kidneys (Wolfrum et al., 2007; Osborn et al.,...

Coenzyme Q10, Statin, and Spinocerebellar Ataxias (P6.047)
CONCLUSIONS:CoQ10 is associated with better clinical outcome in SCA1, 2, and 3 whereas statins are associated with worse clinical outcome in SCA6. These drug exposures did not appear to influence clinical progression within 2 years. CoQ10 and statins may have only symptomatic effects or require a longer period of time for disease modification.Study Supported by:American Brain Foundation Research Fellowship, Rare Disease Clinical Research Network RC1NS068897, and NINDS K08 NS083738.Disclosure: Dr. Kuo has nothing to disclose.

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...
