Abstract

Extensive cellular heterogeneity exists within specific immune-cell subtypes classified as a single lineage, but its molecular underpinnings are rarely characterized at a genomic scale. Here, we use single-cell RNA-seq to investigate the molecular mechanisms governing heterogeneity and pathogenicity of Th17 cells isolated from the central nervous system (CNS) and lymph nodes (LN) at the peak of autoimmune encephalomyelitis (EAE) or differentiated in vitro under either pathogenic or non-pathogenic polarization conditions. Computational analysis relates a spectrum of cellular states in vivo to in-vitro-differentiated Th17 cells and unveils genes governing pathogenicity and disease susceptibility. Using knockout mice, we validate four new genes: Gpr65, Plzp, Toso, and Cd5l (in a companion paper). Cellular heterogeneity thus informs Th17 function in autoimmunity and can identify targets for selective suppression of pathogenic Th17 cells while potentially sparing non-pathogenic tissue-protective ones.

  • scRNA-seq has been widely used to reveal the characteristics of immunity in different fields.

    “It is notable that scRNA-seq has been widely used to reveal the characteristics of immunity in different fields. 6-10”

    From Single-Cell RNA Sequencing to Dissect the Immunological Network of Autoimmune Myocarditis. (2020) · cites this paper as [6]

    The Results section (page not available in our copy) shows that the paper uses single-cell RNA-seq to characterize Th17 immune cells, and the Introduction describes its value for interrogating cell states. This supports an example of the method revealing immune-cell characteristics, but the paper does not establish that it has been widely used across different fields. (LLM, conf=0.84)

  • Recent studies have successfully applied co-expression-like approaches to single-cell data to identify pathogenicity regulators that co-vary with pro-inflammatory genes.

    “by Gaublomme et al. [37] to identify pathogenicity regulators that co-vary with pro-inflammatory genes”

    From Mapping gene regulatory networks from single-cell omics data (2018) · cites this paper as [37]

  • Even cells of the same type can exhibit substantial heterogeneity, reflecting finer sub-types, regulated functional variation, or inherent stochasticity.

    “even cells of the same ‘type’ can exhibit substantial heterogeneity, reflecting finer sub-types, regulated functional variation, or inherent stochasticity1–6”
  • The number of undetected transcripts is correlated with batch effects and other metrics of library quality, and weakly expressed transcripts are more frequently undetected.

    “Indeed, the number of undetected transcripts is correlated to batch effects60 and other metrics of library quality, and transcripts that are weakly expressed when detected are also more frequently undetected1.”
  • The main axes of variation in scRNA-seq data are often dominated by technical factors such as library complexity, proportion of reads aligned to the genome, and proportion of detected transcripts.

    “The main axes of variation (i.e., first few principal components) in scRNA-seq data are often dominated by additional technical factors1,60, such as library complexity64, proportion of reads that were successfully aligned to the genome, and proportion of detected transcripts”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
