The Science Behind Coronavirus Series III: Mutations – Los Angeles Times

In the third installment of the Los Angeles Times series “The Science Behind Coronavirus,” Dr. Patrick Soon-Shiong, the executive chairman of the Los Angeles Times, examines the pandemic’s newest threat: a second wave of global infections fueled by mutations to the virus. The mutations, as Dr. Soon-Shiong explains, raise critical questions about the potential for re-infection by new variants, and pose the problem that therapies and vaccines may not be as effective as hoped.

Severely ill COVID-19 patients display impaired exhaustion features in SARS-CoV-2-reactive CD8+ T cells – Science

The molecular properties of CD8+ T cells that respond to SARS-CoV-2 infection are not fully known. Here, we report on the single-cell transcriptomes of >80,000 virus-reactive CD8+ T cells, obtained using a modified Antigen-Reactive T cell Enrichment (ARTE) assay, from 39 COVID-19 patients and 10 healthy subjects. COVID-19 patients segregated into two groups based on whether the dominant CD8+ T cell response to SARS-CoV-2 was ‘exhausted’ or not. SARS-CoV-2-reactive cells in the exhausted subset were increased in frequency and displayed lesser cytotoxicity and inflammatory features in COVID-19 patients with mild compared to severe illness.

Residual symptoms and lower lung function in patients recovering from SARS-CoV-2 infection – European Respiratory Journal

About half of the patients recovering from SARS-CoV-2 have persistent symptoms and reduced lung function as long as 2 months after infection. This is common even in younger SARS-CoV-2 convalescents with few comorbidities.
