Abstract

fetched live from OpenAlex

The fate of CD8+ T cells is sculpted not only by antigenic stimulation and cytokine milieu but, increasingly, by metabolic context. In their recent Nature Immunology study, Sharma and colleagues report a previously underappreciated and temporally constrained nutrient-sensing mechanism in which methionine (Met) availability during the earliest minutes of T-cell receptor engagement exerts durable control over T-cell function, exhaustion, and antitumor efficacy. Their findings expose a critical metabolic window, within just 30 minutes of activation, during which extracellular Met shapes intracellular signaling and transcriptional fate decisions through a posttranslational mechanism involving arginine methylation of the calcium-activated potassium channel KCa3.1. These findings open the door to timed interventions that modulate Met and potentially enhance T-cell responses.

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.
