Systematic Evaluation of Nasal Immune Cell Sampling and Antigen-specific T cell Detection using Cryopreserved Nasal Swabs

Wesley Huisman, Mark A. Power, Nina Le Bert, Elena Mitsi, Nile Verleur, Lisa A. King, D.W. de Vos, Giovanni E. Loe-Sack-Sioe, Helen R. Wagstaffe, Renate S. Hagedoorn, Iman Satti, Corine H. GeurtsvanKessel, Arnaud Marchant, Pieter Pannus, Mirjam H.M. Heemskerk, , Simon P. Jochems

This study evaluates nasal immune cell sampling methods and antigen-specific T cell detection using cryopreserved nasal swabs, finding that flocked swabs yield more cells and cryopreservation preserves functional T cells.

Maternal vaccination timing shapes the composition and maturation of antibody clonotypes transferred to the newborn

Aisha Yesbolatova, Lowrey Peyton, Nicholas C. Curtis, Tae Kim, Jinyoung Yoon, Hunter J. Melton, Noor M Taher, Tae-Geun Yu, Brian H. Kim, Dhvanir N. Kansara, Matthew R. Stoner, Ellison Ober, Emma Varella, Pieter Pannus, Larissa DeBrabandere, , Jiwon Lee

This study examines how maternal vaccination timing affects antibody clonotype transfer to newborns, finding that earlier vaccination leads to more diverse but less persistent clonotypes, while later vaccination results in more persistent, affinity-matured antibodies in cord blood.

Late induction of IgG4 following SARS-CoV-2 mRNA vaccination in pregnant and non-pregnant individuals includes clonotypes raised early in the response

Dhvanir N. Kansara, Tae-Geun Yu, Neel Kansara, Noor M Taher, Aisha Yesbolatova, Larissa DeBrabandere, Joshua A. Weiner, Gabriela Kovacikova, Andrew P. Hederman, Pieter Pannus, Stéphanie Depickère, Maria E Goosens, An Vercoutere, Nicolás Dauby, Kevin K. Ariën, , Margaret E. Ackerman

This study examines how pregnancy affects humoral immunity after SARS-CoV-2 mRNA vaccination, finding delayed IgG4 induction and clonotype characteristics associated with pregnancy.
