Demonstrates a novel wave model for signal flow in pathways, suggesting innovative insights into cellular processes.
The study commenced with a discrete model of signal flow in signalling pathways based on a system of sequential, one-step, irreversible reactions with unknown kinetics and governed by a linear master equation. Building upon this, a continuous, non-linear model was created with a (1+1)-dimensional, integro-differential, space- and time-dependent wave equation that describes signal flow as a non-local, spatiotemporal, chirped envelope, dissipative solitary wave X(s,t) with two-phase hyperbolic up- and down-chirps. The phase and group velocities, and the group delay and dispersion, were determined. Transitions within the temporal and spatial profiles of X(s,t) were shown to be governed by inhomogeneous or homogeneous Poisson processes, respectively. The spatial profile represents a novel and hitherto unexploited tool for investigating signalling pathways. The energy characteristics of both profiles were determined and applied to signalling pathways that target IκB kinase activity in macrophages and T-bet transcription factor expression in T helper cells.
