Generation of one iPSC line (IMEDEAi007-A) by Sendai Virus transduction of PBMCs from a Psoriasis donor.

Psoriasis is a chronic inflammatory skin disease that speeds up the life cycle of skin cells, forming scales and red patches that are itchy and sometimes painful. It is a complex disease of autoimmune origin and genetic predisposition with more than 10 different loci associated. Here we described the production of an iPSC line generated by Sendai Virus (Klf4, Oct3/4, Sox2 and c-Myc) reprogramming of Peripheral Blood Mononuclear Cells (PBMCs) from a Psoriasis patient.

Generation of a human iPSC line (IMEDEAi008-A) derived from natural homozygous CCR5-Δ32 PBMCs enriched in the pro-erythroblast population.

A 32 base pair deletion in the C-C chemokine receptor type gene (CCR5-Δ32), the main Human Immunodeficiency Virus (HIV) co-receptor results in a non-functional protein. Individuals homozygous for the CCR5-Δ32 mutation are resistant to HIV infection. Here we report the generation, from pro-erythroblast enriched Peripheral Blood Mononuclear Cells (PBMCs) from a naturally occurring CCR5-Δ32/Δ32 individual, of the fully characterized iPSC line IMEDEAi008-A.

iPSC-Derived Intestinal Organoids from Cystic Fibrosis Patients Acquire CFTR Activity upon TALEN-Mediated Repair of the p.F508del Mutation.

Cystic fibrosis (CF) is the main genetic cause of death among the Caucasian population. The disease is characterized by abnormal fluid and electrolyte mobility across secretory epithelia. The first manifestations occur within hours of birth (meconium ileus), later extending to other organs, generally affecting the respiratory tract.

New Bicistronic TALENs Greatly Improve Genome Editing.

Genome editing has become one of the most powerful tools in present-day stem cell and regenerative medicine research, but despite its rapid acceptance and widespread use, some elements of the technology still need improvement. In this unit, we present data regarding the use of a new, more efficient type of transcription activator-like effector nuclease (TALEN) for gene editing. Our group has generated bicistronic genes in which classical TALEN coding sequences are linked by 2A elements to different reporter molecules, such as fluorochromes (TALEN-F) or membrane receptors (TALEN-M).
