    Aggressive cerebral cavernous malformations (CCMs) are found to grow through a three-hit cancer-like mechanism, involving gain of function of a gene that promotes vascular growth, and loss of function of genes that suppress it.

    Lipopolysaccharide derived from gut bacteria can accelerate the formation of cerebral cavernous malformations by activating TLR4 on endothelial cells, and polymorphisms that increase expression of the genes encoding TLR4 or its co-receptor CD14 are associated with higher CCM lesion burden in humans.

    New drugs and more focused therapy might cut down on atrial fibrillation and reduce the incidence of stroke.

    Tat-NR2B9c, a PSD-95 inhibitor, is shown to reduce stroke-induced behavioural and neuroanatomical deficits in cynomolgous macaques when administered in the presence of an ischemic penumbra, suggesting the potential of PSD-95 inhibition as a neuroprotectant strategy for clinical investigation.

    Uninterrupted blood flow through the small vessels of the brain is essential for cerebral function and viability. Small clots that form in the vessels can be — but are not always — removed by haemodynamic forces and the fibrinolytic system. Here, a third mechanism for the removal of emboli is described: the endothelial cells that line the vessel walls send out membrane projections that envelop the emboli and move them into the perivascular parenchyma tissue. In aged mice, this process is markedly delayed.
