Comprehensive mapping of sensory and sympathetic innervation of the developing kidney.

The kidneys act as finely tuned sensors to maintain physiological homeostasis. Both sympathetic and sensory nerves modulate kidney function through precise neural control. However, how the kidneys are innervated during development to support function remains elusive.

Comprehensive mapping of sensory and sympathetic innervation of the developing kidney.

The kidney functions as a finely tuned sensor to balance body fluid composition and filter out waste through complex coordinated mechanisms. This versatility requires tight neural control, with innervating efferent nerves playing a crucial role in regulating blood flow, glomerular filtration rate, water and sodium reabsorption, and renin release. In turn sensory afferents provide feedback to the central nervous system for the modulation of cardiovascular function.
