Specifically in the peripheral nervous system, there's been some work along these lines, primarily in anesthetized experiments, using ChR2-expressing stem cells, which integrate into denervated nerves, and enable optogenetic control of the previously denervated muscles. See here: http://www.ncbi.nlm.nih.gov/pubmed/24700859
We wrote a review recently about what's been happening in optogenetics in the peripheral nervous system/spinal cord. That's here: http://www.ncbi.nlm.nih.gov/pubmed/27147590
Within pharma, Derek Lowe has been blogging for many years, with a mix of posts focusing on new developments as well as broader strategic questions. http://blogs.sciencemag.org/pipeline/ The comment section there is also typically informed.
And you feel every ounce of those when reading them. Most good versions of this class of book are this heavy (typically prescribed for the late 'undergrad'/first year grad introductory class reading). The neuroscience equivalent (Kandel, Schwartz, Jessell) is 8.7 pounds, with very thin pages.
[1] Such as: "In 2014, Judah Rosner from the National Institutes of Health drew attention to this “fake fact” in a letter to Microbe magazine. More recent estimates, he noted, put the total number of human cells at anywhere from 15 trillion to 724 trillion, and the number of gut microbes at anywhere between 30 trillion and 400 trillion. Which gives a ratio that can best be expressed as ¯\_(ツ)_/¯."
Stanford's release on this goes into more scientific detail, and has a nice interview with the senior author in which she discusses the background behind the work.
There's a news article about the paper that Science wrote up, which goes into some of the history of the work and has a broad sampling of views on the relevance of this paper within the broader context. http://news.sciencemag.org/biology/2015/03/ultrasound-therap...
