ORIGINAL ARTICLE: Repertoire and Clonality of T‐Cell Receptor Beta Variable Genes Expressed in Endometrium and Blood T Cells of Patients with Recurrent Spontaneous Abortion
Bibliographic record
Abstract
PROBLEM: Recurrent spontaneous abortion (RSA) is a relatively common disorder, the underlying causes of which are thought to be immunological in most cases. METHOD OF STUDY: Expression profile and clonality pattern of T-cell receptor beta variable (TCRBV) genes in endometrium and blood of patients with RSA were investigated by semi-quantitative reverse transcriptase polymerase chain reaction (RT-PCR) using BV gene-specific primers. Relative expression of each BV family was determined and clonal expansion of the over-expressed genes was assessed by analysis of CDR3 length polymorphism. RESULTS: Compared to blood, relative expression of four TCRBV genes was significantly higher in the endometrium of RSA group. Over-expressed genes, except for TCRBV3, all had restricted and oligoclonal patterns of expression in the endometrium. CONCLUSION: Endometrial T cells have a skewed TCRBV repertoire with restricted transcript heterogeneity, which is shared by both groups and minor variations observed in this pattern in RSA patients may reflect more recent and/or repeated exposure to nominal antigens or superantigens.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
