Phagocytosis in macrophages is regulated by the ATP-binding cassette family gene ABCF1
Bibliographic record
Abstract
Abstract Phagocytosis is a conserved biological mechanism that is integral to tissue remodeling, clearance of apoptotic cells, and immune defense in animals. Additionally, it serves as a pivotal means of sustenance for diverse unicellular eukaryotes. In the context of mammals, this crucial role is fulfilled by specific cell types such as macrophages, monocytes, dendritic cells, and neutrophils. It is orchestrated by an array of receptors, kinases, cytoskeletal elements, and enzymes, working collaboratively to enable the recognition, engulfment, and internalization of particles. Despite its profound significance, the intricate mechanisms underpinning the regulation of this phenomenon remains enigmatic. In this study, we present compelling evidence indicating the involvement of ABCF1, a member of the ATP-binding cassette family, in the FcγRIIA phagocytic pathway. ABCF1’s contribution lies in facilitating downstream signal activation through interactions with Src family members and SYK, pivotal players in this cascade. Additionally, our findings highlight ABCF1’s essentiality in the biosynthesis of various SFKs (Src family kinases) and MAPKs (mitogen-activated protein kinases). These molecules collectively oversee the orchestration of phagocytic cup formation, a pivotal step governing the engulfment process within macrophages. Consequently, the regulation of ABCF1 presents a potential avenue for modulating phagocytosis, allowing for the precise modulation of this fundamental process to either enhance or attenuate according to the specific physiological demands.

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.
