A stroke not only causes acute damage to the brain, but can also have long-term health implications for other organs -- such as the heart. Researchers have worked on the hypothesis that the high rate of comorbidities that develop after a stroke could have a common immunological cause.
And they actually managed to find it: The origin of the dysfunctions in other parts of the body lies in the immunological memory of the blood-forming cells in bone marrow.
Using single-cell sequencing techniques, Liesz and his team demonstrated the presence of permanent proinflammatory changes in the transcriptome of certain immune cells in several organs. In other words, certain gene segments are transcribed differently there after the stroke, which unbalances the proteome. These epigenetic modifications occur most frequently in the heart, where they can cause scarring and impair pumping function.
