Engineered dendritic cells from cord blood and adult blood accelerate effector T cell immune reconstitution against HCMV.

Human cytomegalovirus (HCMV) harmfully impacts survival after peripheral blood hematopoietic stem cell transplantation (PB-HSCT). Delayed immune reconstitution after cord blood (CB)-HSCT leads to even higher HCMV-related morbidity and mortality. Towards a feasible dendritic cell therapy to accelerate de novo immunity against HCMV, we validated a tricistronic integrase-defective lentiviral vector (coexpressing GM-CSF, IFN-α, and HCMV pp65 antigen) capable to directly induce self-differentiation of PB and CB monocytes into dendritic cells processing pp65 ("SmyleDCpp65").

Intracellular delivery of full length recombinant human mitochondrial L-Sco2 protein into the mitochondria of permanent cell lines and SCO2 deficient patient's primary cells.

Mutations in human SCO2 gene, encoding the mitochondrial inner membrane Sco2 protein, have been found to be responsible for fatal infantile cardioencephalomyopathy and cytochrome c oxidase (COX) deficiency. One potentially fruitful therapeutic approach for this mitochondrial disorder should be considered the production of human recombinant full length L-Sco2 protein and its deliberate transduction into the mitochondria. Recombinant L-Sco2 protein, fused with TAT, a Protein Transduction Domain (PTD), was produced in bacteria and purified from inclusion bodies (IBs).
