Abstract
The debate about the state of the marsupial immune system has entered a new era with the recent publication of the tammar wallaby (Macropus eugenii) genome. The aim of this study was to investigate two important components of the T-cell signalling cascade in M. eugenii to determine whether there are any significant differences between the genome and the expressed gene sequences and to elucidate the putative structures. Molecular methods, predominantly RACE PCR and RT–PCR, using cDNA obtained from mRNA isolated from M. eugenii lymph node tissue, were used to determine the sequence of functional motifs in the TCR? and ZAP-70 molecules. Structure prediction algorithms were used to determine their secondary and tertiary structures for comparison with the structures elucidated by X-ray crystallography in humans and other mammals. Differences between the genome and the expressed sequence were found in the ZAP-70 molecule. Homology modelling demonstrated that the predicted structure of the TCR? molecule was different from those of other mammals while the structure of the ZAP-70 molecule was very similar. It is concluded that the T-cell signalling cascade in the adaptive immune system of marsupials shows similar features to that of other mammals.

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 it
