Single-cell landscape of bronchoalveolar immune cells in patients with COVID-19.

TLDR
Single-cell transcriptome and T cell receptor analysis of bronchoalveolar lavage fluid suggests enrichment of proinflammatory macrophages in patients with severe COVID-19 and the presence of clonally expanded CD8 + T cells in Patients with moderate CO VID-19.
Abstract
Respiratory immune characteristics associated with Coronavirus Disease 2019 (COVID-19) severity are currently unclear. We characterized bronchoalveolar lavage fluid immune cells from patients with varying severity of COVID-19 and from healthy people by using single-cell RNA sequencing. Proinflammatory monocyte-derived macrophages were abundant in the bronchoalveolar lavage fluid from patients with severe COVID-9. Moderate cases were characterized by the presence of highly clonally expanded CD8+ T cells. This atlas of the bronchoalveolar immune microenvironment suggests potential mechanisms underlying pathogenesis and recovery in COVID-19.

SCENIC: Single-Cell Regulatory Network Inference And Clustering

TL;DR: SCENIC (Single Cell rEgulatory Network Inference and Clustering) is the first method to analyze scRNA-seq data using a network-centric, rather than cell-centric approach and allows for the simultaneous tracing of genomic regulatory programs and the mapping of cellular identities emerging from these programs.

Human Tissue-Resident Memory T Cells Are Defined by Core Transcriptional and Functional Signatures in Lymphoid and Mucosal Sites

TL;DR: A core transcriptional profile within the CD69+ subset of memory CD4+ and CD8+ T cells in lung and spleen that is distinct from that of CD69- TEM cells in tissues and circulation is identified, providing a unifying signature for human TRM and a blueprint for designing tissue-targeted immunotherapies.

Virus-specific memory CD8 T cells provide substantial protection from lethal severe acute respiratory syndrome coronavirus infection.

TL;DR: Using a prime-boost immunization approach, it is shown that virus-specific CD8 T cells protect susceptible 8- to 10-month-old mice from lethal SARS-CoV challenge, and future vaccines against emerging coronaviruses should emphasize the generation of a memoryCD8 T cell response for optimal protection.
