ULBP1, 2, 3: novel MHC class I-related molecules that bind to human cytomegalovirus glycoprotein UL16, activate NK cells
Bibliographic record
Abstract
New members of the extended MHC class I-like family were identified based on their ability to bind human cytomegalovirus glycoprotein UL16 and/or their mutual homology. Soluble UL16 binding proteins (ULBP) competed with each other for binding to NK cells. Treatment of human and mouse NK cells with ULBP led to increased production of cytokines/chemokines, proliferation, cytotoxic activity and up-regulation of activation-associated surface molecules. The presence of ULBP during the stimulation phase of the CTL assay caused increased cytotoxic activity. Addition of soluble recombinant UL16 protein inhibited the biological activities mediated by ULBP, suggesting the existence of a novel mechanism utilized by CMV to evade elimination by the host immune system.
Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

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.
