Immune reminisces about a year in COVID-19 immunology, Steph’s receiving the Pfizer vaccine, and answers to listener questions about a challenge study with common cold CoVs, T cell exhaustion, how CD4 T cells control infections, and more.
Immune catches up on COVID listener email, including discussions about long-term COVID, cross-reactive memory to SARS-CoV-2, common mucosal surfaces, the risky business of peptide mega-pools, immunodominant epitopes and much more.
Sallie joins Immune to discuss her career, emphasizing the importance of a good mentor and the ability to pivot, and her research, which has focused on mother to child transmission of infectious diseases including HIV/AIDS, CMV, and more recently, COVID-19/SARS-CoV-2.
Immune describes the striking loss of germinal centers in lymph nodes and spleen in patients with severe COVID-19, providing an explanation for short-lived humoral immunity and limited somatic hypermutation of antibodies to SARS-CoV-2.
Immune examines antibodies to SARS-CoV-2, including the relationship between severe COVID-19 and anti-spike antibodies, kinetics of production, and correlates of protection.
Immune explains a study demonstrating T cells that react with SARS-CoV-2 epitopes in individuals who have never been infected with the virus, implying cross-reactivity with common cold coronaviruses.
Immune explains a study of 125 COVID-19 patients by deep immune profiling, which revealed three immunotypes associated with poor clinical prognosis or recovery.
Brianne Barker joins Immune to discuss the immune response to infection with SARS-CoV-2, including immune respones, pathogenesis, immunopathology and more.
