Immune discusses immunological imprinting, also called original antigenic sin, in the context of infection with SARS-CoV-2 and influenza virus.
Immune discusses the current understanding of immune memory to SARS-CoV-2 infection and COVID-19 vaccines, which supersedes that of any other acute infectious disease.
Cindy, Steph, Brianne, and Vincent do a rapid review of 11 immunology papers, including a wiring diagram for the immune system, group A streptococcus vaccines, systems immunology prediction of vaccines, class switch towards IgG4 after SARS-CoV-2 mRNA vaccination, very bad B cells, monoclonal antibody to two streptococcal M protein epitopes, transcriptional atlas of response to 13 vaccines, impact of SARS-CoV-2 exposure history on T cell and IgG response, neutrophilic inflammation predisposes to RSV infection, commensals avoiding recognition, and continuous germinal center invasion contributes to diversity of immune response.
Immune reveals a CD8+ regulatory subset of T cell subset that suppress pathogenic T cells and are active in autoimmune diseases and infectious diseases including COVID-19.
Immune 50: Red blood cells are immune sentinels
- November 11, 2021
- Tagged as: anemia, COVID-19, DNA, immune, immunology, innate immunity, macrophage, red blood cell, sepsis, Tlr9
Immune reviews evidence that toll-like receptor 9 on the surface of red blood cells binds DNA, leading to uptake by macrophages and innate immune activation.

- Tagged as: antibody, B cells, coronavirus, COVID-19, immune, immunology, memory B cells, pandemic, SARS-CoV-2
Christian joins Immune to discuss the humoral memory response in a cohort of 87 individuals 1.3 and 6.2 months after infection with SARS-CoV-2.
Immune 41: Zebrafish immunology with Madina Wane
- January 25, 2021
- Tagged as: anosmia, COVID-19, fish, gills, immune, immunology, pandemic, SARS-CoV-2, zebrafish
Madina joins Immune to explain how the immune system of zebrafish gills compares to its functional counterpart in mammals, the lungs, and to discuss a zebrafish model for understanding olfactory loss during COVID-19.
Immune 40: COVID-19 nuances
- December 30, 2020
- Tagged as: antibody, coronavirus, COVID-19, immune, immunity, immunology, pandemic, SARS-CoV-2, T cell, T cell exhaustion, vaccine
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.
