Cell Metadata

non-TRDV2+ gdT

Full Name: non-TRDV2+ gamma-delta T cell
Closest Ontology Term: gamma-delta T cellCL:0000798
Synonyms Terms that have the same, or nearly the same, meaning as the selected cell type.: non-TRDV2+ gamma-delta T-lymphocyte, non-TRDV2+ gamma-delta T-cell, non-TRDV2+ gammadelta T cell, non-TRDV2+ gd T cell, non-TRDV2+ gamma-delta T lymphocyte
Category Class of which the cell type is a subclass.: T cellCL:0000084
Ontology Assessment Disagreements with any aspect of the Cell Ontology.: —
Marker Gene Evidence Gene markers used by researcher to assign this cell annotation.: TRDC, TRGC1, TRGC2, CCL5, KLRK1, NKG7
Canonical Marker Genes: TRDC, TRGC1, TRGC2, CCL5, KLRK1, NKG7
Rationale: γδ T cells are a distinct subgroup of T cells containing T cell receptors (TCR) γ and δ chains. In this cluster we identified a clear signature of gd T cells: KLRD1, KLRC2, TRGC1, TRGC2 and TRDC (Pizzolato et al., 2019)
Rationale DOI: 10.1073/pnas.1818488116

Set of Labels Description: The annotation provided in this first version comprises 42 categories that provide a stable categories to classify single-cell transcriptomes of SLOs, useful for tools like Azimuth (see external URLs). In the next version, we will add a more detailed classification, encompassing all cell types and states identified in the tonsil atlas. A validation cohort was included to confirm the presence and accuracy of each annotation this latter level, using criteria such as cell neighborhood preservation, conservation of bona fide marker genes, and annotation confidence derived from the KNN classifier. For a full description and interpretation of this validation cohort, please refer to the final section of the manuscript.
Annotation Method: manual
