Bioelectric and Mechanotransductive Modulation of Mast Cell Activation Thresholds as a treatment for MCAS

This paper presents a novel conceptual framework for understanding and treating mast cell hypersensitivity, with a focus on Mast Cell Activation Syndrome (MCAS). Rather than emphasizing downstream mediator release or immune signaling pathways, the work reframes mast cell dysfunction as a disorder of altered activation threshold regulation. The paper proposes that mast cell sensitivity is governed, in part, by intrinsic bioelectric and mechanotransductive mechanisms that shape cellular excitability upstream of calcium-dependent activation. By integrating principles from immunology, biophysics, and systems biology, the paper introduces a unified model in which membrane potential stability, ion channel dynamics, and mechanical signal processing converge to determine whether mast cells activate in response to diverse stimuli. This framework offers a biologically plausible explanation for the heterogeneity and unpredictability of triggers observed in MCAS and highlights previously underexplored regulatory layers that may be therapeutically targeted.
