Abstract
The liver is a sizeable visceral organ whose primary functions involve nutrient metabolism, clearance of toxins, and energy storage. Besides these critical functions, the liver is also a major immunological site. It is populated by several specialized resident immune cells, including B cells, T Cells, dendritic cells, and several populations of macrophages. It is also the site for the production and release of acute-phase proteins during inflammation. One reason for garrisoning these immune sentinels and effectors in the liver is its relative location in the circulatory system. The liver is the first significant organ downstream of the intestine, where blood originating from the intestine enters the liver through the portal vein. This organization facilitates the liver's uptake and processing of nutrient-rich blood directly from the intestinal source. However, the intestine is also home to trillions of microbes, many of which are commensals but also represent potential pathogens. As such, the portal blood supply represents an avenue for systemic infection. To sterilize the portal blood, the liver immune system filters pathogens, which is primarily accomplished by liver macrophages. Here, we will discuss the major populations of macrophages resident in the liver, their location, functions, development, and role in maintaining the liver in the face of injury and infection.

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.
