I went looking for better information and I found the initial study published in Nature in 2016 and based on Japanese news sources it does look like the “vaccination” delivery is going into clinical trials soon. The study was quite interesting and the proposed mechanism of action makes sense and was tested both in vitro and in vivo. Here’s the link to the 2016 article. (It’s kind of dense on the renal physiology and immunology side of things, but the science is sound and potentially can be extended to treat humans with kidney disease in the future.)
