Microglia in Health and Diseases: Integrative Hubs of the Central Nervous System (CNS)
Bibliographic record
Abstract
Microglia are usually referred to as "the innate immune cells of the brain," "the resident macrophages of the central nervous system" (CNS), or "CNS parenchymal macrophages."These labels allude to their inherent immune function, related to their macrophage lineage.However, beyond their classic innate immune responses, microglia also play physiological roles crucial for proper brain development and maintenance of adult brain homeostasis.Microglia sense both external and local stimuli through a variety of surface receptors.Thus, they might serve as integrative hubs at the interface between the external environment and the CNS, able to decode, filter, and buffer cues from outside, with the aim of preserving and maintaining brain homeostasis.In this perspective, we will cast a critical look at how these multiple microglial functions are acquired and coordinated, and we will speculate on their impact on human brain physiology and pathology. MICROGLIA ACROSS THE LIFE SPANU nderstanding microglia requires becoming acquainted with their ontogeny, for which we rely on a concordant (where compared) set of observations in humans and mice.As with other tissue macrophages, such as those in skin and liver (Langerhans and Kupffer cells; Mrquez-Ropero et al. 2020), microglia are not derived from bone marrow myeloid progenitors that

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.
