An mRNA vaccine induces antimycobacterial immunity by activating DNA damage repair and autophagy
Bibliographic record
Abstract
Effective vaccines are urgently needed for the control of tuberculosis (TB). Here, we report that an mRNA TB vaccine is highly effective and exhibits both prophylactic and therapeutic activity in the zebrafish model of TB. Adult zebrafish immunized with the mRNA vaccine survived significantly longer after Mycobacterium marinum challenge compared to those immunized with the DNA vaccine. Furthermore, post-infection treatment with the mRNA vaccine drastically reduced the bacterial burden. The mRNA vaccine activated multiple DNA break repair systems that are essential for the normal development and function of adaptive immunity, but did not activate the canonical DNA damage responses that promote cell death. This highlights a profound connection between DNA damage repair and the activation of immune responses under physiological processes of immunization. Remarkably, the mRNA vaccine induced autophagy in granulomas, coinciding with bacterial killing and cell survival. Collectively, these findings demonstrate that the mRNA vaccine elicits potent innate and adaptive immunity, providing effective host protection against mycobacterial challenge.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 teacher head, not a consensus.
