Selected cohort requirements

Samples meeting selected requirements: 0 cases / 0 controls

View matching samples

21 case / 12 control samples elsewhere in the study have incomplete or conflicting evidence; they are not included above

Patient pairs verified in indexed sample metadata: 0

A case/control comparison meeting these requirements is not confirmed.

Counts describe samples, not independent patients. Pair verification uses explicit subject identifiers in indexed sample metadata. Zero verified pairs does not establish that the study is unpaired; reported matched-normal design alone is insufficient.

Summary

Deregulated myeloid cells infiltrating to the joints likely contribute to rheumatoid arthritis (RA) pathogenesis through multiple mechanisms, including the secretion of proinflammatory cytokines and the induction of pathogenic adaptive Th17 cells, that mediate joint damage. However, the individual contribution of specific myeloid subsets such as CD1c+ and CD141+ conventional dendritic cells (cDC) to RA development and progression has been poorly studied and remains unclear. In particular, the potential molecular mechanisms specifically affecting CD1c+ cDCs in RA patients and their functional implications have not been characterized. Using RNA-seq, multiparametric flow cytometry and in vitro functional assays, we compared in parallel transcriptional, phenotypical and functional characteristics of monocytes, CD1c+ and CD141+ cDCs from the blood and synovial fluid of RA patients.

Overall design

We performed RNA sequencing using RNA from Monocytes, Dendritic Cd1c+ and Dendritic Cd141 cells obtained from blood/sinovial fluid of Rheumatoid Arthritis versus healthy/CPPD matched controls.

Blockers

  • 9 samples are still unassigned.

Next Steps

  • Resolve unassigned or review-needed samples in the grouping table.

Analysis Preparation Checklist

4/6 ready

Group labels reviewed

Needs review

Siftome proposed case and control labels, but no reviewer confirmation is stored yet.

Open the sample grouping CSV and confirm group labels before analysis.

Minimum sample count met

Ready

Both groups meet the minimum of 2 samples.

Confirm whether the cohort is large enough for the intended statistical analysis.

Processed counts available

Ready

Processed data availability is marked true in the GEO index.

Verify that downloaded processed files contain usable count or expression identifiers.

Ambiguous samples handled

Needs review

0 review-needed samples and 9 unassigned samples remain.

Resolve ambiguous and unassigned samples before finalizing the contrast.

Exclusion decisions recorded

Ready

No hard-excluded samples were detected by the current rules.

Record any manual exclusions in the downstream analysis notes.

Source traceability preserved

Ready

The dataset and sample accessions can be traced back to GEO.

Keep GEO accessions with exported metadata.

Bioinformatician Review

Bioinformatician review required

Ask a bioinformatician to review grouping, count availability, exclusions, and design before DE.

Analysis readiness has blockers that must be resolved before DE.

One or more samples are unassigned and need manual grouping decisions.

Mixed specimen/source groups must be separated before analysis.

Why This Is Ranked Here

Tumor vs normal
Not suitable Dataset does not meet the current suitability threshold.

Applied Review Decisions

No active review decisions affect this ranking.

Derived Classifications

  • Disease context Rheumatoid arthritis Disease context came from Normalization rules.
  • Likely case group Rheumatoid arthritis 21 samples
  • Likely control group Control 12 samples

Intent Interpretation

  • Downgrade or exclusion reason Downgraded for tissue search because specimen/source classes are mixed. Derived from current-intent ranking reasons.

Ranking Facts

Supporting evidence

  • Comparison: Disease/model vs control. Specimen: Mixed specimen/source. Comparison suitability: 0%.
  • Prioritized assay: bulk RNA-seq is the active assay expectation.
  • Interpreted disease metadata: Rheumatoid arthritis.
  • Processed data is available for downstream review.
  • External evidence: PubMed links 2 publications; 2 DOIs available: PMID 36194479, PMID 37916875.
  • Publication context: NLRC4-mediated activation of CD1c+ DC contributes to perpetuation of synovitis in rheumatoid arthritis.. JCI insight, 2022. PMID 36194479. DOI 10.1172/jci.insight.152886.
  • Publication context: MICa/b-dependent activation of natural killer cells by CD64(+) inflammatory type 2 dendritic cells contributes to autoimmunity.. The EMBO journal, 2023. PMID 37916875. DOI 10.15252/embj.2023113714.

Cautions

  • Downgraded for tissue search because specimen/source classes are mixed.
  • Disease/control design without a tumor/normal comparison is outside tumor/normal triage.
  • Mixed specimen/source dataset downgraded until tissue samples are clearly separated.
  • Overall score capped because comparison suitability is weak for the selected search intent.
  • Comparison suitability score is below the Phase 1 recommended threshold.
