The new coronavirus, known as SARS-CoV-2, may be using part of the human body’s own immune response against us, a new study suggests. The novel coronavirus is known to use a keyhole called the ACE2 receptor to “unlock” a cell and get inside, where it replicates and wreaks havoc. Now, researchers have found that the gene that encodes the ACE2 receptor may be stimulated by interferons, one of the body’s main defenses against viruses. When a foreign pathogen invades, interferons act like “first responders”; the immune system releases these proteins to alert other cells that there’s a pathogen in the body.
