The Ellender group recently demonstrated that distinct embryonic progenitor pools in the lateral ganglionic eminence (LGE), which generate the spiny projection neurons of the striatum, convey key features to their progeny. Of these features it was the synaptic integration within large-scale neuronal circuits that was most profoundly impacted by progenitor pool of origin. For example, the striatal spiny projection neurons derived from so-called apical intermediate progenitors expressing the gene tubulin-1 were mainly innervated by the medial prefrontal cortex – a brain region that has been implicated in a plethora of neurological and psychiatric disorders. This finding allows for further exploration and study of this important pathway in the future.

New BHF study offers potential of new clinical options for cardiac treatment

A new study, led by Professor Kim Dora in association with Professor Raimondo Ascione at the University of Bristol, has shown abnormalities in the tiny blood vessels of human hearts which cannot be detected by current heart scans. Poor myogenic (automatic) tone, where blood flow in these vessels is abnormal, is thought to develop independent of disease in the larger arteries, which can be treated using stents or bypass surgeries.
