CD8+ tissue-resident memory T-cell development depends on infection-matching re...
Barros, Leandro; Piontkivska, Daryna; Figueiredo-Campos, Patrícia; Fanczal, Júlia; Ribeiro, Sofia Pereira; Baptista, Marta; Ariotti, SilviaImmunological memory is critical for immune protection, particularly at epithelial sites, which are under constant risk of pathogen invasions. To counter invading pathogens, CD8+ memory T cells develop at the location of infection: tissue-resident memory T cells (TRM). CD8+ T-cell responses are associated with type-1 infections and type-1 regulatory T cells (TREG) are important for CD8+ T-cell development, howe...
Seroprevalence of anti‐SARS‐CoV‐2 antibodies in COVID‐19 patients and healthy v...
Figueiredo-Campos, Patricia; Blankenhaus, Birte; Mota, Catarina; Gomes, Andreia; Serrano, Marta; Ariotti, Silvia; Costa, Catarina; Nunes-Cabaço, HelenaSARS-CoV-2 has emerged as a human pathogen, causing clinical signs, from fever to pneumonia-COVID-19-but may remain mild or asymptomatic. To understand the continuing spread of the virus, to detect those who are and were infected, and to follow the immune response longitudinally, reliable and robust assays for SARS-CoV-2 detection and immunological monitoring are needed. We quantified IgM, IgG, and IgA antibodi...

To understand the continuing spread of the virus, to detect those who are and were infected, and to follow the immune response longitudinally, reliable and robust assays for SARS-CoV-2 detection and immunological monitoring are needed.

Immunology: skin T cells switch identity to protect and heal
Ariotti, Silvia; Veldhoen, MarcSkin-resident T cells protect against invasive microorganisms. A new study reports that commensal-specific type-17 (but not type-1) T cells in the skin are poised to switch to a type-2 response upon tissue injury and contribute to wound repair.
