Reduced expression of TLR3, TLR10 and TREM1 by human macrophages in Chronic cavitary pulmonary aspergillosis, and novel associations of VEGFA, DENND1B and PLAT
Bibliographic record
Abstract
Chronic cavitary pulmonary aspergillosis (CCPA) is an uncommon but serious pulmonary disease of humans, with an annual mortality rate of 10–30%. It is caused by the fungus Aspergillus fumigatus. Patients are overtly immunocompetent; however, some immunogenetic defect is likely. To investigate this, we performed a genetic association study analysing biologically plausible candidate genes in 112 CCPA patients and 279 healthy controls, and investigated gene expression in monocyte-derived macrophages from patients and controls at baseline and during stimulation with A. fumigatus. Single-nucleotide polymorphisms (SNPs) associated with CCPA were found in TLR1, CLEC7A (dectin-1), PLAT (n = 2), VEGFA, and DENND1B. Macrophages from CCPA patients showed low TLR3 and TLR10 expression and high TREM1 expression at baseline, as compared with macrophages from healthy subjects, with major expression differences being seen in most Toll-like receptors (TLRs) during 9 h of co-culture with A. fumigatus. The differences in baseline expression between the healthy and CCPA groups suggest roles for TLR3 and TLR10 in susceptibility to CCPA, and the association of SNPs in PLAT (n = 2), VEGFA and DENND1B supports novel roles for plasminogen activation and angiogenesis and of these genes specifically in susceptibility to CCPA.

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.
