Abstract
The humoral immune response mounted in BALB/c mice against bovine serum albumin or cholera toxin B subunit was compared when the antigens were associated with liposomes composed of either archaeal ether lipids or conventional lipids. Antibody titres in sera from mice immunised intraperitoneally were elevated to an extent comparable to those achieved with Freund's adjuvant by encapsulating bovine serum albumin in archaeal lipid vesicles (archaeosomes) of about 200 nm diameter. Comparison among six archaeosome and three conventional liposome compositions established that archaeosomes were generally much superior in potentiating an immune response. Further, only two immunisations, at the most, were needed to achieve close to the maximum antibody titre, as shown with archaeosomes composed of the polar lipids from Methanobrevibacter smithii, an inhabitant of the human colon. A similar positive response to presenting the more immunogenic cholera B subunit protein to the immune system of mice was shown for M. smithii archaeosomes. Encapsulation of the antigen in the archaeosome was necessary to achieve the full humoral response. This represents the first study to our knowledge where archaeosomes have been evaluated in vivo as possible antigen carriers.

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
