Tubuloglomerular feedback (TGF) contributes to hemodynamics control by adjusting the single nephron glomerular filtration rate according to the chloride concentration sensed downstream. To analyze the TGF system, which is a negative feedback loop, we first formulate model equations consisting of a partial differential equation that describes solute conservation along the thick ascending limb, and a delay equation that describes the feedback response. Depending on model parameters, in particular the feedback delay and gain, the model may predict limit-cycle oscillations or a time-independent steady state, following a transient perturbation. We analyze the dynamic behaviors of the TGF model by linearizing the model equations and deriving a characteristic equation. Numerical simulations can also be conducted to assist in the interpretation of the analysis.
