Incidentally my sister just got a paper published in the New England Journal with a similar approach (kill switch) for use in gene therapy http://www.nejm.org/d

Incidentally my sister just got a paper published in the New England Journal with a similar approach (kill switch) for use in gene therapy http://www.nejm.org/doi/full/10.1056/NEJMoa1106152 http://www.nejm.org/doi/full/10.1056/NEJMoa1106152 This could be pretty important work to make gene therapy much safer. A single dose of dimerizing drug, given to four patients in whom GVHD developed, eliminated more than 90% of the modified T cells within 30 minutes after administration and ended the GVHD without recurrence.
