Head to head narcolepsy/hypersomnia study

At the sleep research meeting in San Antonio this year, there were signs of an impending pharmaceutical arms race in the realm of narcolepsy. The big fish in a small pond, Jazz Pharmaceuticals, was preparing to market its recently FDA-approved medication: Sunosi/solriamfetol. Startup Harmony Biosciences was close behind with pitolisant, already approved in Europe. On the horizon are experimental drugs designed to more precisely target the neuropeptide deficiency in people with classic narcolepsy type 1 Read more

Anti-inflammatory approach suppresses cancer metastasis in animal models

An anti-inflammatory drug called ketorolac, given before surgery, can promote long-term survival in animal models of cancer metastasis, a team of scientists has found. The research suggests that flanking chemotherapy with ketorolac or similar drugs -- an approach that is distinct from previous anti-inflammatory cancer prevention efforts -- can unleash anti-tumor immunity. The findings, published in Journal of Clinical Investigation, also provide a mechanistic explanation for the anti-metastatic effects of ketorolac, previously observed in human Read more

I3 Venture awards info

Emory is full of fledgling biomedical proto-companies. Some of them are actual corporations with employees, while others are ideas that need a push to get them to that point. Along with the companies highlighted by the Emory Biotech Consulting Club, Dean Sukhatme’s recent announcement of five I3 Venture research awards gives more examples of early stage research projects with commercial potential. This is the third round of the I3 awards; the first two were Wow! Read more

Aging, CVD risk factors and progenitor cells

Cardiologists Ibhar Al Mheid, Arshed Quyyumi and colleagues from Emory’s Clinical Cardiovascular Research Institute recently published a paper that weaves together insights from past research on circulating progenitor cells. They tease apart the influences of age and cardiovascular disease (CVD) risk factors on these cells, whose regenerative capacity has made them the target of much investigation. From this research, one can infer that the circulatory system has a limited regenerative capacity, and stress upon the system earlier in life depletes it later.

Circulating progenitor cells are rare cells in the blood that can become white or red blood cells, as well as endothelial cells, which line blood vessels and repair them when damaged by cardiovascular disease. Quyyumi and his colleagues have sought to deliver progenitor cells, derived from the patient’s own bone marrow, to the heart – or less invasively, spur them out of the bone marrow with drugs.
