A new CU Boulder study, published Dec. 12 in the journal Cell, sheds light on the subject by identifying what the authors describe as an "immune system tuning dial," which originated as a bug in ...

"A light-activated probe reveals TB immune system evasion mechanisms." ScienceDaily. ScienceDaily, 22 April 2025. <www.sciencedaily.com / releases / 2025 / 04 / 250421163100.htm>.

The immune system is complex, and its main function is to protect the organism from viruses, infections, and other hostile agents.

The domain is activated by blue light, which switches the protein function on and off. They then re-engineered human natural killer immune cells with the light-sensitive septin-7 protein.

Funded by the Biotechnology and Biological Sciences Research Council (BBSRC), the study on mice shows that the brain’s hypothalamus controls how the immune system adapts during fasting, through ...

In the study, first author Anna Nogalska and her colleagues found striking differences in how quickly the immune system ages—even among lab mice with the same genetic background raised in ...

De Leo showed that up to 600 genes inside each immune system cell are activated as they take on inv ading pathogens — evidence that the cells themselves change to defeat an enemy.

Previously, Ben Swarts, Sloan Siegrist and colleagues developed light-activated chemical probes that mimic some of these compounds and studied how they might interact with a host’s immune cells. Now, ...
