Compensatory Anion Currents in Kv1.3 Channel-deficient Thymocytes
Bibliographic record
Abstract
Kv1.3 is a voltage-gated potassium channel with roles in human T cell activation/proliferation, cell-mediated cytotoxicity, and volume regulation and is thus a target for therapeutic control of T cell responses. Kv1.3 is also present in some mouse thymocyte subsets and splenocytes, but its role in the mouse is less well understood. We report the generation and characterization of Kv1.3-deficient (Kv1.3-/-) mice. In contrast to wild-type cells, the majority of Kv1.3-/- thymocytes had no detectable voltage-dependent potassium current, although RNA and protein for several potassium channel subunits were found in the thymocyte population. Surprisingly, the level of chloride current in the Kv1.3-/- thymocytes was increased approximately 50-fold over that in wild-type cells. There were no abnormalities in lymphocyte types or absolute numbers in thymus, spleen, and lymph nodes and no obvious defect in thymocyte apoptosis or T cell proliferation in the Kv1.3-/- animals. The compensatory effects of the enhanced chloride current may account for the apparent lack of immune system defects in Kv1.3-/-mice.

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.
