I have Ms. This article is very interesting. Weird how genes work.


The analysis suggests that herders migrating from the Pontic Steppe (specifically central/eastern Europe) introduced genes that increased susceptibility for MS to the populations of northern Europe. The results also show that, at the time, the introduction of these genes represented a process known as “positive natural selection.” This means that the genes provided an advantage – they likely helped herders to fight off infections they were exposed to because of the animals they were herding. Over time, however, the genes began to contribute to the immune response that attacks the body’s own nervous system in MS.

Fascinating how genetics can carry both advantages and challenges over time. It’s incredible to see how historical migrations and lifestyles shaped health outcomes like MS today. Thanks for sharing this.
