How Zika virus induces congenital microcephaly

An international team of researchers identified a specific mechanism leading to Zika virus-associated microcephaly, involving protein misfolding and endoplasmic reticulum stress. This triggers the unfolded protein response, promoting apoptosis in neuronal cells and reducing cortical neuron development.
