Dorsal Root Ganglion Neurons In Chemotherapy Induced Neuropathy is an important component in the neurobiology of neurodegenerative diseases. This page provides detailed information about its structure, function, and role in disease processes.
Overview
Dorsal root ganglion (DRG) neurons are pseudounipolar sensory neurons located in the dorsal root ganglia that transmit sensory information from the periphery to the spinal cord. These neurons are particularly vulnerable to chemotherapy-induced neuropathy (CIPN), a dose-limiting complication of cancer treatment. Common chemotherapeutics causing DRG toxicity include platinum agents, taxanes, vinca alkaloids, and proteasome inhibitors.
Chemotherapy-induced peripheral neuropathy (CIPN) is a dose-limiting side effect of many chemotherapeutic agents. Dorsal root ganglion (DRG) neurons are particularly vulnerable due to their unique anatomy and lack of a blood-nerve barrier.

Dorsal Root Ganglion Neurons in Chemotherapy-Induced Neuropathy
Dorsal Root Ganglion Neurons In Chemotherapy Induced Neuropathy is an important component in the neurobiology of neurodegenerative diseases. This page provides detailed information about its structure, function, and role in disease processes.
Overview
Dorsal root ganglion (DRG) neurons are pseudounipolar sensory neurons located in the dorsal root ganglia that transmit sensory information from the periphery to the spinal cord. These neurons are particularly vulnerable to chemotherapy-induced neuropathy (CIPN), a dose-limiting complication of cancer treatment. Common chemotherapeutics causing DRG toxicity include platinum agents, taxanes, vinca alkaloids, and proteasome inhibitors.
Chemotherapy-induced peripheral neuropathy (CIPN) is a dose-limiting side effect of many chemotherapeutic agents. Dorsal root ganglion (DRG) neurons are particularly vulnerable due to their unique anatomy and lack of a blood-nerve barrier.
Dorsal root ganglion (DRG) neurons are sensory neurons whose cell bodies reside in the dorsal root ganglia along the spinal cord[^1]. These neurons transmit sensory information including pain, temperature, and touch from the periphery to the central nervous system.
Chemotherapy-induced peripheral neuropathy (CIPN) is a dose-limiting side effect of many chemotherapeutic agents that primarily affects DRG neurons due to their unique anatomy and vulnerability[^2]. DRG neurons lack a blood-nerve barrier, making them exposed to circulating toxins. Additionally, their large cell bodies and long axons create high metabolic demands that make them susceptible to mitochondrial dysfunction.
Common chemotherapies causing CIPN include: platinum agents (oxaliplatin, cisplatin), taxanes (paclitaxel, docetaxel), vinca alkaloids (vincristine), and proteasome inhibitors (bortezomib)[^3].
