    The Unfolded Protein Response Components IRE1α and XBP1 Promote Human Coronavirus Infection

    Investigators found that the human coronaviruses HCoV-OC43, human coronavirus OC43, and SARS-CoV-2 both robustly activated the IRE1α–XBP1 branch of the unfolded protein response in cultured cells.

    Histidine-Rich Protein II Nanoparticle Delivery of Heme Iron Load Drives Endothelial Inflammation in Cerebral Malaria

    The authors discovered an important mechanism for blood–brain barrier disruption that was driven by unique features of histidine-rich protein II, a protein secreted by Plasmodium falciparum during the blood stage of malaria infection.
