We profiled adaptive immunity in COVID-19 patients with active infection or after
recovery and created a repository of currently >14 million B and T cell receptor
(BCR and TCR) sequences from the blood of these patients. The B cell response
showed converging IGHV3-driven BCR clusters closely associated with SARS-CoV-2
antibodies. Clonality and skewing of TCR repertoires were associated with
interferon type I and III responses, early CD4(+) and CD8(+) T cell activation,
and counterregulation by the co-receptors BTLA, Tim-3, PD-1, TIGIT, and CD73.
Tfh, Th17-like, and nonconventional (but not classical antiviral) Th1 cell
polarizations were induced. SARS-CoV-2-specific T cell responses were driven by
TCR clusters shared between patients with a characteristic trajectory of
clonotypes and traceability over the disease course. Our data provide fundamental
insight into adaptive immunity to SARS-CoV-2 with the actively updated repository
providing a resource for the scientific community urgently needed to inform
therapeutic concepts and vaccine development.
