Reviewer #3 (Public review): Loss of Flower/FLWR-1 induces an increase in neuronal excitability and causes defective recycling of synaptic vesicles
Bibliographic record
Abstract
The Flower protein is proposed to couple synaptic vesicle fusion to recycling in different model organisms. It is supposed to trigger activity-dependent bulk endocytosis by conducting Ca2+ at endocytic sites. However, this mode of action is debated. Here, we investigate the role of the nematode homolog (FLWR-1) in neurotransmission in Caenorhabditis elegans. Our results confirm that FLWR-1 facilitates the recycling of synaptic vesicles at the neuromuscular junction. Ultrastructural analysis of synaptic boutons after hyperstimulation surprisingly reveals an accumulation of endosomal structures in flwr-1 mutants. These findings do not support a role of FLWR-1 in the formation of bulk endosomes but rather a function in their breakdown following cleavage from the plasma membrane. Unexpectedly, loss of FLWR-1 conveys increased neuronal excitability which causes an excitation-inhibition imbalance. Finally, we obtained evidence that this increased transmission at the neuromuscular junction might be caused by deregulation of MCA-3, the nematode homolog of the plasma membrane Ca2+ ATPase (PMCA).

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
