Drugs are more effective at certain times of day [technologyreview.com]:

The study also revealed that the liver is more susceptible to infections such as malaria at certain points in the circadian cycle, when fewer inflammatory proteins are being produced—possibly because its response to pathogens declines after meals, when it has typically been exposed to an influx of microorganisms that might trigger inflammation even if they are not harmful.

“One of the earliest applications for this method could be fine-tuning drug regimens of already approved drugs to maximize their efficacy and minimize their toxicity,” says Professor Sangeeta Bhatia, SM ’93, PhD ’97, a member of MIT’s Koch Institute for Integrative Cancer Research and the Institute for Medical Engineering and Science (IMES), who is the senior author of the new study [doi.org].

The MIT researchers are now working with collaborators to analyze a cancer drug they suspect may be affected by circadian cycles, and they hope to investigate whether this may be true of drugs used in pain management as well. They are also taking advantage of the cycles in inflammatory signals to study infections that are usually difficult to establish in engineered livers, including certain types of malaria.
