Abstract

fetched live from OpenAlex

Mycobacterium tuberculosis (M. tb), the causative agent of tuberculosis, poses a significant global health problem. Toll-like receptors (TLRs) on the surface of phagocytic cells facilitate pathogen recognition and mount an inflammatory innate immune response upon activation. The role of TLR2 and TLR4 in the innate immune response to M. tb is intricate and complex, with evidence supporting both host and pathogen beneficial outcomes. Using CRISPR-Cas9 editing to generate TLR2 and TLR4 knockout macrophages, I assessed the role of these receptors in mycobacterial infection. I demonstrated that the absence of either of these receptors negatively impacts the replication and survival of M. tb within the macrophage during late-stage infection. Secondly, I found that TLR2 and TLR4 have differential, gene-specific roles in the induction of pro-inflammatory cytokines. Ultimately these findings support the notion that TLR2 and TLR4 serve pathogen beneficial roles in infection.

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.
