chronic constriction injury of the distal infraorbital nerve (dion-cci) in mice to study trigeminal neuropathic pain

Neuropathic pain arises from damage to the somatosensory nervous system, leading to abnormal transmission of sensory signals to the brain. Somatosensory nerve damage does not always lead to neuropathic pain, but the prevalence increases with the severity of clinical neuropathy1,2. Neuropathic pain patients experience specific symptoms such as spontaneous sensations (burning, pins and needles, electric sensations) and abnormally intense or prolonged pain to innocuous or noxious stimulation that tend to become chronic and resistant to treatment with conventional pain medication3. Significant progress in the field of neuropathic pain research stems from the discovery that loosely constricting ligatures around the sciatic nerve in rats leads to behaviors resembling human neuropathic pain conditions4. The animals display reduced thresholds to heat, cold, and mechanical stimulation, and exhibit nocifensive behaviors. Despite the inherent biological differences in pain processing between humans and rodents, animal models are a valuable tool for studying the underlying mechanisms in the development of neuropathic pain and testing newly proposed treatment strategies.
Sensory reflex-based pain testing paradigms have been extensively used in neuropathic pain models, but measuring ongoing pain or other frequently accompanied disturbances (sleeping disorder, depression, anxiety) has not received sufficient attention considering that these are common clinical symptoms affecting quality of life5,6,7,8. Face grooming behavior in rats has been documented as a measure of spontaneous neuropathic pain following chronic constriction injury (CCI) of the infraorbital nerve (IoN)9,10. In addition, rats also develop hyperresponsiveness to mild tactile stimulation of the IoN territory, which is indicative of mechanical allodynia.
Compared to mice, because of their larger size, rats are better suited for surgical injuries. However, mice offer cost and space efficiency and require smaller drug quantities. Also, the advent of transgenic technology has further boosted the use of mice11,12. Therefore, the overall goal of this procedure is to perform a surgical infraorbital nerve injury in mice, similar to that in rats, that induces changes in spontaneous and evoked behavior for the study of trigeminal neuropathic pain.

Lesión crónica por constricción del nervio infraorbitario distal (DIoN-CCI) en ratones para estudiar el dolor neuropático del trigémino

The overall goal of this procedure is to perform an infraorbital nerve injury in mice to study the development of trigeminal neuropathic pain and to test new treatment strategies. Isolated phase grooming behavior after infraorbital nerve ligation is one of the few animal models to study spontaneous neuropathic pain. But its use has long been hampered by the complexity of performing an infraorbital nerve ligation.Compared to sensory reflex based pain testing, such as from fray or withdrawal responses from heat or cold stimulation, measuring spontaneous or ongoing pain has not received sufficient attention, considering that this is an important clinical symptom affecting quality of life. The distal approach to the infraorbital nerve has the advantage of being a surgically less demanding procedure than the intraorbital approach. It is minimally invasive, and can be performed without using a stereotaxic frame.

El objetivo general de este procedimiento es realizar una lesión del nervio infraorbitario en ratones para estudiar el desarrollo del dolor neuropático del trigémino y probar nuevas estrategias de tratamiento. El comportamiento de acicalamiento en fase aislada después de la ligadura del nervio infraorbitario es uno de los pocos modelos animales que estudia el dolor neuropático espontáneo. Pero su uso se ha visto obstaculizado durante mucho tiempo por la...
