Abstract
Research relating to host inflammatory processes during malaria infection has focused on Toll-like receptors, membrane-bound receptors implicated in innate sensing, and phagocytosis of parasitized erythrocytes by host cells. This is the first study to examine the role of Nod proteins, members of the Nod-like receptor (NLR) family of cytoplasmic proteins involved in pathogen recognition, in a murine model of cerebral malaria (Plasmodium berghei ANKA, PbA). Here, we find that nod1nod2(-/-) mice infected with PbA show no difference in survival or parasitemia compared with wild-type infected animals. However, cytokine levels, notably those associated with NLR activation including interleukin (IL)1-beta, KC, and MCP-1, and proteins linked to malaria pathogenesis, such as interferon-gamma (IFN-gamma), were decreased in the nod-1nod2(-/-) animals. We therefore demonstrate for the first time that Nod proteins are activated in response to parasites, and they play a role in regulating host inflammatory responses during malaria infection.

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 it
