Abstract
Summary Microglia and non‐professional immune cells (endothelial cells, neurons) participate in the recognition and removal of pathogens and tissue debris in the injured central nervous system through major pro‐inflammatory processes. However, the mechanisms involved in regulating these responses remain ill‐characterized. We herein show that CD93, also known as complement C1qRp/AA4 stem cell marker, has an important role in the regulation of inflammatory processes. The role of CD93 was evaluated in two models of neuroinflammation. We used the MOG‐experimental autoimmune encephalomyelitis (EAE) model and the antibody‐dependent EAE (ADEAE), which were induced in wild‐type and CD93 knockout mice. We found that CD93 was highly expressed by neurons, endothelial cells and microglia (ramified >> amoeboid). Astrocytes and oligodendrocytes did not to express CD93. We further observed that CD93‐deficient (CD93 −/− ) mice presented a more robust brain and spinal cord inflammation in EAE and ADEAE. Encephalitis in CD93 −/− was characterized by increased numbers of infiltrating M1 macrophages (CD11c + CD206 − ) and amoeboid microglia exhibiting a more activated phenotype (Tomato Lectin high Cox2 high ). Damage to and leakage through the blood–brain barrier was increased in CD93 −/− animals and was associated with a more robust neuronal injury when compared with wild‐type EAE mice. We propose that CD93 is an important neuro‐immune regulator to control central nervous system inflammation.

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
