Atherosclerotic cardiovascular diseases, including myocardial infarction and ischemic stroke, are the leading cause of mortality worldwide. A team of researchers shows that the protein MIF-2/D-DT acts as an atypical chemokine and a non-cognate ligand of CXCR4, which helps promote the development of atherosclerosis and inflammation in blood vessels. The study improves our understanding of how inflammation in blood vessels is connected to liver problems in atherosclerotic diseases and points out potential treatment pathways.

The Amyloid Cascade model of Alzheimer’s disease suggests that plaques of amyloid-β (Aβ) are the primary cause of the disease and trigger other pathological changes, such as the spread of abnormal tau protein. The exact connection between amyloid and tau buildup is not clear. Researchers now found an essential piece to this puzzle: by analyzing PET and MRI imaging, they show that amyloid drives the spread of tau by evoking neuronal hyperconnectivity.

The accumulation of amyloid-β plaques is known to initiate a pathological cascade that leads to neurodegeneration and dementia. How these plaques are formed is only partially understood. Here, we provide evidence that aggregation of Apolipoprotein E (APOE) together with amyloid-β within the lysosomal system of microglia may trigger the generation of amyloid-β plaques.

Researchers have compared a type of immune cells (CD8 T cells) of monozygotic twin pairs, where one twin has MS while the other shows no signs or subclinical signs of neuroinflammation. They found specific changes indicating that CD8-positive T cells play a crucial role in the early stages of multiple sclerosis. These findings can potentially open up new therapeutic avenues and could be used to develop improved diagnostic methods.

The central nervous system's decreased ability to regenerate as we age limits its ability to recover after demyelinating injuries, such as MS lesions. Researchers have now discovered that through training the immune system inactive microglia can be reprogrammed, restoring their ability to repair neuronal lesions.

Recurrent strokes in the days and weeks after the initial event are a common problem in patients whose original cause was arteriosclerosis. An international team of researchers has uncovered the mechanisms underlying this process and proposed a new therapy involving DNase enzymes to break down cell-free DNA. If confirmed in humans, these findings could lead to improved stroke therapy.

A stroke not only causes immediate damage to the brain, but it can also have long-term health effects on other organs, such as the heart. In a recent study published in Cell, researchers demonstrate that persistent pro-inflammatory changes in myeloid cells after stroke play a direct role in the development of cardiac fibrosis, independent of other factors that can lead to cardiovascular issues.

Age-related myelin damage leads to white matter inflammation, but its impact on chronic neurodegenerative diseases remains unclear. A recent study reveals that amyloidosis alone can cause age-related oligodendrocyte and myelin damage in mouse models of Alzheimer's disease. The research team discovered that CD8 T cells contribute to neurodegenerative diseases associated with amyloidosis by abnormally activating microglia, resulting in myelin damage.

Researchers have made significant progress in unraveling novel mechanisms of glia-to-neuron conversion. Using novel methods in epigenome profiling, they identified that a posttranslational modification of the reprogramming neurogenic transcription factor profoundly impacts epigenetic rewiring and the improvement in neuronal programming. They identified a novel protein as key player in this conversion process, namely the transcriptional regulator YingYang1 that physically interacts with the neurogenic factor to open up the chromatin.
