Diagnostic ultrasound imaging has proven to be effective in diagnosing various respiratory diseases in human and animal subjects. We demonstrate a comprehensive ultrasound protocol utilized by Dr. Zuo's lab to analyze diaphragm kinetics specifically in mouse models. This is also a non-invasive research technique which can provide quantitative information on mouse respiratory muscle function.

Compound muscle action potential recording quantitatively assesses functional diaphragm innervation by phrenic motor neurons. Whole-mount diaphragm immunohistochemistry assesses morphological innervation at individual neuromuscular junctions. The goal of this protocol is to demonstrate how these two powerful methodologies can be used in various rodent models of spinal cord disease.

We describe a method for tracking the endomembrane rupture elicited by the intracellular bacteria Shigella flexneri and Mycobacterium tuberculosis upon host cell invasion. Our assay makes use of CCF4, a host cytoplasmic FRET probe in live or fixed cells. This reporter is degraded by an enzyme activity present on the bacterial surface.

Diaphragm thickness and function can be assessed in healthy individuals and critically ill patients using point-of-care ultrasound. This technique offers an accurate, reproducible, feasible, and well-tolerated method for evaluating diaphragm structure and function.
FAQs
Traumatic pressure changes can tear the diaphragm and interrupt its normal excursion during breathing. Because this muscle helps separate and mechanically coordinate the chest and abdomen, a defect can reduce the effectiveness of thoracic movement. The resulting impairment is mechanical rather than purely neural, although it can alter the conditions under which respiratory motor circuits must operate.
When abdominal organs move into the thoracic cavity, they occupy space that would otherwise support lung expansion. This displacement can compress the lungs and reduce ventilation, adding a spatial limitation to the loss of normal diaphragmatic movement. The combination helps explain why respiratory impairment may reflect both the size of the structural defect and the extent of thoracic compression.
The phrenic nerves and cervical spinal circuits coordinate activity in the diaphragm as part of respiratory control. Diaphragm rupture does not simply represent a failure of neural signaling; it also creates structural damage in the muscle that receives that command. Studying both components helps distinguish disrupted neural control from impaired force transmission and movement.
Traumatic pressure changes and penetrating injury represent different mechanisms that can produce the same type of diaphragmatic damage. Pressure-related injury reflects force applied to the body, whereas penetration directly disrupts tissue. Recognizing the cause provides context for evaluating the defect, interpreting respiratory findings, and considering how structural damage may have affected nearby thoracic and abdominal anatomy.
Evaluation combines clinical imaging with respiratory assessment. Imaging can help identify the diaphragmatic defect and the movement of abdominal organs into the thoracic cavity, while respiratory assessment indicates how the injury affects breathing. Considering both structural and functional findings is important because the visible tear and its effect on ventilation do not necessarily represent identical degrees of impairment.
Surgical repair is intended to restore the disrupted separation and mechanics between the chest and abdomen. By addressing the structural defect, treatment can help reduce the abnormal movement of abdominal organs into the thoracic cavity and support more effective respiratory mechanics. Its relevance extends beyond anatomy because improved mechanical conditions influence how respiratory neural commands are expressed.
This injury provides a context for examining how cervical spinal circuits and phrenic nerve activity interact with damaged respiratory muscle tissue. Neural commands may remain important even when structural disruption limits diaphragmatic movement. Comparing respiratory control with the resulting mechanical performance can clarify how nervous-system coordination and tissue integrity jointly determine breathing outcomes.
