Virus-mediated delivery of antibody targeting TAR DNA-binding protein-43 mitigates associated neuropathology
Bibliographic record
Abstract
The cytoplasmic aggregation of TAR DNA-binding protein-43 (TDP-43) is a hallmark of degenerating neurons in amyotrophic lateral sclerosis (ALS) and subsets of frontotemporal dementia (FTD). In order to reduce TDP-43 pathology, we generated single-chain (scFv) antibodies against the RNA recognition motif 1 (RRM1) of TDP-43, which is involved in abnormal protein self-aggregation and interaction with p65 NF-κB. Virus-mediated delivery into the nervous system of a scFv antibody, named VH7Vk9, reduced microgliosis in a mouse model of acute neuroinflammation and mitigated cognitive impairment, motor defects, TDP-43 proteinopathy, and neuroinflammation in transgenic mice expressing ALS-linked TDP-43 mutations. These results suggest that antibodies targeting the RRM1 domain of TDP-43 might provide new therapeutic avenues for the treatment of ALS and FTD.

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.
