The chirality, or handedness, of nanoparticles shapes how they engage with the immune system — a finding that might help to inform the design of vaccines and anticancer therapeutics.

United States Latest News, United States Headlines

Shape is all-important for molecules, especially when it comes to a property known as chirality .

A chiral molecule exists in two forms, called enantiomers, that are chemically identical, but are mirror images of each other, and that interact with other molecules in different ways. Chiral molecules have long been used in drug design — and some molecules can even be tailored to interact with the body in enantiomer-specific ways.

I couldn't read this article (behind paywall), but I have long been fascinated with the chirality of organic molecules in cells. Nature is cool no matter how close you look. RIP E.O. Wilson

Nanoparticle asymmetry shapes an immune responseThe chirality, or handedness, of nanoparticles is shown to be a key factor in determining how well such particles engage with the immune system — a finding that might help to inform the design of vaccines and anticancer therapeutics. - Francis Crick, Nobel Prize recipient for discovery of DNA structure: 'Every time I write a paper on the origin of life, I determine I will never write another one, because there is too much speculation running after too few facts.'

Deep immune phenotyping reveals similarities between aging, Down syndrome, and autoimmunityUsing immune clock models and a new analysis pipeline, scientists in ScienceTM find individuals with DownSyndrome may be more vulnerable to autoimmune disorders due to accelerated aging of their immune systems. Inflammaging ScienceTM Oh ScienceTM My son ,now 24, has (please use the correct term) 'Down's Syndrome' (not DOWN) and has an autoimmune disease. However, so do/did myself (duel RA & PA as well as signs of Lupis) and his great grandfather (ALS). Going to be hard to trace autoimmune with trisomy not being inherited.
