The results of a study led by Northern Arizona University and the Translational Genomics Research Institute (TGen), an affiliate of City of Hope, suggest the immune systems of people infected with COVID-19 may rely on antibodies created during infections from earlier coronaviruses to help fight the disease.

COVID-19 isn’t humanity’s first encounter with a coronavirus, so named because of the corona, or crown-like, protein spikes on their surface. Before SARS-CoV-2 the virus that causes COVID-19 humans have navigated at least 6 other types of coronaviruses.
The study sought to understand how coronaviruses (CoVs) ignite the human immune system and conduct a deeper dive on the inner workings of the antibody response. The published findings, “Epitope-resolved profiling of the SARS-CoV-2 antibody response identifies cross-reactivity with endemic human coronaviruses,” appear in the journal

As Alzheimer’s tangle pathology progresses, neurodegeneration sweeps through the brain in a stereotypical fashion. But why do some neurons perish early on, while their neighbors persist until the bitter end? A study published January 11 in Nature Neuroscience addressed this question by tracing the gene-expression profiles of neurons in the brains of people who died in the early or late stages of the disease. Among myriad subpopulations of cells, the researchers zeroed in on subsets of excitatory neurons that express the transcription factor RORB as the first to succumb. Initially in the entorhinal cortex, and then later in the outer neocortex, excitatory neurons bearing this particular marker were selectively vulnerable to tau accumulation, and to death. The study, led by Lea Grinberg and Martin Kampmann, both at the University of California, San Francisco, also pegged a type of reactive astrocyte that may shirk its duties of protecting and nourishing neurons. In all,
