Chicken biliary exosomes enhance CD4<sup>+</sup>T proliferation and inhibit ALV-J replication in liver
Bibliographic record
Abstract
Exosomes, which are small membrane vesicles of endocytic origin, carry lipids, RNA/miRNAs, and proteins and have immune modulatory functions. In this study, we isolated exosomes from the bile of specific pathogen-free chickens, 42-43 days of age, by using an ultracentrifugation and filtration method. The density of the exosomes, isolated by sucrose gradient fractionation, was between 1.13 and 1.19 g/mL. Electron microscopic observation of the liver showed that exosomes were present in the space of Disse and bile canaliculus. Chicken biliary exosomes displayed typical saucer-shaped, rounded morphology. Using liquid chromatography mass spectrum methodology, 196 proteins, including exosomal markers and several unique proteins, were identified and compared with mouse biliary exosomes. Noteworthy, CCCH type zinc finger antiviral protein was found on chicken biliary exosomes never described before. Furthermore, our data show that chicken biliary exosomes promote the proliferation of CD4(+) and CD8(+) T cells and monocytes from liver. In addition, chicken biliary exosomes significantly inhibit avian leukosis virus subgroup J, which is an oncogenic retrovirus, from replicating in the DF-1 cell line. These data indicate that chicken biliary exosomes possess the capacity to influence the immune responses of lymphocytes and inhibit avian leukosis virus subgroup J (ALV-J).

How this classification was reachedexpand
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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
