Abstract

fetched live from OpenAlex

This is a protocol used to perform T cell assays using whole blood (collected in EDTA tubes) or cells from bronchoalveolar lavage (BAL). We have successfully used this protocol for rhesus macaques, cynomolgus macaques, and African green monkeys (although antibody mix provided was titrated on macaques). It allows the characterization of T cells into Th1 and Th2 (or Tc1 and Tc2) phenotypes. It technically offers 64 different activation profiles (4 cytokines + CD107a + CD69). The nature and concentration of the stimulant is left unspecified as we have used different ones depending on reagent availability. This protocol was designed to deal with samples coming from containment labs (> CL2) at our facility. If you are using this protocol at a different facility please ensure that proper testing and approvals are in place. The protocol can be used for experiments completed entirely in CL2, simply go from step 17 directly to 31.

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.

Not 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.
