Abstract
Stabilized antisense lipid particles (SALP) have been developed for the systemic delivery of oligonucleotides. The impact of intravenous SALP administration was measured with respect to activation of natural killer (NK) and NK1.1+ T (NKT) cells in the livers of immunocompetent mice. Treatment with a SALP containing a highly mitogenic oligonucleotide (INX-6295) generated an increase in NK cytolytic activity and cell number within the liver but did not appear to affect the number of hepatic NKT cells or their cytolytic activity. The same results were observed after intravenous administration of the mitogenic oligonucleotide alone. Interestingly, treatment with a SALP containing a weakly mitogenic oligonucleotide (INX-6300) also activated the liver NK cells, whereas the oligonucleotide alone was unable to elicit these effects. The NK stimulatory activity of a SALP containing INX-6300 required both lipid and oligonucleotide components. These results demonstrate that in addition to modifying the pharmacokinetics and biodistribution of intravenously administered oligonucleotides, SALP possess immunostimulatory activity independent of oligonucleotide mitogenicity, which can serve as an adjuvant to antisense therapies for cancer.

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 it
