Changes in Peripheral Blood Mononuclear Cells - Novel Evidence for an Immunomodulatory Aspect in Bell’s Palsy?
Bibliographic record
Abstract
Background : Patients with Bell’s Palsy (BP): a very common neuropathy of the facial nerve-showed significant decreases of T- and B-lymphocytes in earlier studies. Besides a viral infection an autoimmune process leading to this disease has been discussed. Methods : 15 patients with BP and 15 healthy, age-matched individuals were included in this study. In addition to routine blood parameters peripheral blood mononuclear cells (PBMCs) were isolated by Ficoll density gradient. Afterwards, in CD14 + (monocytes), CD68 + (macrophages), CD3 + (T-lymphocytes) or CD19 + (B-lymphocytes) the percentage of cells, expressing pro-inflammatory (CD40, TNF- α , and COX-2), pro-apoptotic (Caspase-3, PARP), pro-adhesive (CD38) and oxidative stress-related (MnSOD) proteins were measured by two-color fluorescence-activated cell sorter analyses. Results: In comparison to healthy individuals, patients with BP revealed significantly elevated plasma levels of C-reactive protein and total leukocyte count, while levels of T- and B-lymphocytes were significantly decreased. In BP patients all subpopulations under test showed a significant increase in percentage of CD38 + as well as of pro-inflammatory (CD40 + , TNF- α + ) cells; additionally monocytes showed a significant increase in percentage of MnSOD positive cells. Conclusions: Our data shows new evidence for an involvement of the immune system in BP. Therefore, we suggest that future investigations of PBMCs in BP patients represent a very promising approach to further elucidate possible pathomechanisms. doi:10.4021/ jnr108 w

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.
