Summary: New research has demonstrated the significant role that an irregular body clock plays in driving inflammation in the body’s immune cells, with implications for the most serious and prevalent diseases in humans.
Dr George Timmons, lead author on the study, said: “Our results add to the growing body of work showing why disruption of our body clock leads to inflammatory and infectious disease, and one of the aspects is fuel usage at the level of key immune cells such as macrophages.”
Dr Annie Curtis, Senior Lecturer at RCSI School of Pharmacy and Biomolecular Sciences and senior author on the paper, added: “This study also shows that anything which negatively impacts on our body clocks, such as insufficient sleep and not enough daylight, can impact on the ability of our immune system to work effectively.”
