Anxious Jew Redux, Professor Ian Robertson & Blindboy

Doctors are great at diagnosing or assigning diagnoses. It is something that makes many of them very happy. & other pitfalls of modern medicine!

Today I listened to a fantastic Blindboy Podcast with the Scottish Psychologist Ian Robertson. Please listen. Here. Actually, maybe read this then decide. I don’t I believe have much success with my Podcast recommendations. I can but try. So. Anxious Jew. I have written about this a few times. It is at the intersection of epigenetics (which my Biologist son tells me I misunderstand) and the…

Nervous in Defence

Our nervous system plays a key role in regulating immunity. Illustrated, for example, by the finding that stimulating a major nerve serving the heart, lungs and gut – the vagus – can relieve a damaging inflammatory response made by the immune system. But many of the details of how these two systems communicate remain to be uncovered. One important link is a kind of T cell, an immune cell that produces a neurotransmitter Ach when it senses release of an adrenalin-like hormone by nerves in response to stresses, such as tissue damage or infection. Called ChAT+ T cells, researchers investigated their role during bacterial infection. On the left is a section of gut of a normal mouse infected with C. rodentium (in red), and on the right gut from a mouse genetically-engineered to lack ChAT+ cells. Without ChAT+ cells the bacterial infection is heavier, demonstrating how important these neuro-immune go-betweens are for host defence.
