Abstract

fetched live from OpenAlex

Dscams (down syndrome cell adhesion molecules) play an important role in the formation of neural circuits. Various studies have highlighted the role of dscams in two major wiring strate- gies, self-avoidance and tiling, leading to broad and uniform branching. The Drosophila dscam1 protein, which has thousands of isoforms formed by alternative splicing, has been shown to confer unique identities to cells and mediate homotypic recognition, homophilic repulsion and consequently self-avoidance behavior between neurites of a single neuron. The Drosophila dscam2 protein mediates homophilic repulsion between projections from the same class of cells, in a process called tiling. The vertebrate dscam has been shown to mediate both tilingand self-avoidance. however, the mechanisms by which this is accomplished in the absence of homotypic recognition are unclear. This review provides an overview of functional similarities and differences between dscam homologues in invertebrate and vertebrate species, and describes some mechanisms proposed to account for these differences.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Not 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.
