Key Highlights
•
A new study reveals that innate immune cells, like macrophages, can “remember” past infections through a sticky mechanism where the signaling molecule IFN-γ gets retained on their surface. This prolonged signaling creates a “trained” state, which could explain how our bodies maintain heightened alertness against future threats long after an initial infection is gone.

Scientists have mapped the intricate dance of electron transfer within the enzyme nitric oxide synthase (NOS), which is crucial for producing nitric oxide, a key signaling molecule in our cardiovascular and nervous systems. They found that the transfer is “conformationally gated,” meaning specific physical movements of the enzyme’s parts must align perfectly to pass the electrons, a discovery that could inform new therapies for heart and brain conditions.

A correction has been issued for a major study on endothelial NADPH oxidases, enzymes that produce reactive oxygen species involved in blood vessel function and disease. This underscores the ongoing process of verification and refinement in science, ensuring that foundational knowledge about cellular signaling in our circulatory system is accurate and reliable.
