Meet the Rosehip Cell, A New Kind of Neuron

“ On Monday, an international team of researchers introduced the world to a new kind of neuron, which, at this point, is believed to exist only in the human brain. The long nerve fibers known as axons of these densely bundled cells bulge in a way that reminded their discoverers of a rose without its petals—so much that they named them ‘rosehip cells.’”

Scientists identify a new kind of human brain cell

“In a new study published today in the journal Nature Neuroscience, Lein and his colleagues reveal one possible answer to that difficult question. The research team, co-led by Lein and Gábor Tamás, Ph.D., a neuroscientist at the University of Szeged in Szeged, Hungary, has uncovered a new type of human brain cell that has never been seen in mice and other well-studied laboratory animals.”

“ These rosehip cells show an immunohistochemical profile matching a single transcriptomically defined cell type whose specific molecular marker signature is not seen in mouse cortex. Rosehip cells in layer 1 make homotypic gap junctions, predominantly target apical dendritic shafts of layer 3 pyramidal neurons, and inhibit backpropagating pyramidal action potentials in microdomains of the dendritic tuft.”
