New Nature Paper Describing Mouse Spinal Projecting Neuron Atlas
Today a study led by Drs. Carla Winter, Anne Jacobi, and Junfeng Su in our lab was published in Nature as part of a collection of papers for the Brain Initiative Cell Census Network 2.0. Utilizing virus-mediated retrograde labeling and snRNA-seq, our study presents a detailed atlas of spinal projecting neurons (SPNs), categorizing them into 3 divisions, 13 subclasses, and 76 types across key brain regions. This taxonomy reveals distinct transcriptomic and anatomical characteristics of SPNs, highlighting their diverse roles in connecting the brain to the spinal cord. By establishing a baseline map of spinal projecting neurons through our study, we can now investigate how spinal cord injuries or stroke affect these diverse neural pathways, potentially leading to the development of targeted therapies.

Non-Invasive Treatments for Spinal Cord Injury
Neural circuits entirely within the spinal cord can control key aspects of locomotion. Even when there is a severe spinal cord injury (SCI) and the connections with the brain are totally broken, these internal circuits, or propriospinal network, may be structurally intact – so why not somehow take advantage of this remaining intraspinal circuitry to help people with SCI? A major technical challenge is how to efficiently target these widely distributed propriospinal neurons.

Zhigang He receives 2019 Reeve-Irvine Research Medal
The Reeve-Irvine Research Medal recognizes an individual, or individuals, who have made highly meritorious scientific contributions in the area of spinal cord repair, and whose research has stood the test of time and scrutiny. The medal includes a $50,000 cash award generously provided by Joan Irvine Smith and the Athalie R. Clarke Foundation. Their kindness has made it possible to continue to recognize the work of pioneering investigators whose work has brought us closer to cures for afflictions affecting the spinal cord. The 20th Reeve-Irvine Research Medal is awarded to Dr. Zhigang He for his critical contributions to promoting axonal plasticity and regeneration after spinal cord injury .

Myelin Restored on Regenerated Optic Nerve Fibers of Mice in Study
Using a two-pronged approach, researchers were able to restore myelin on regenerated nerve fibers in a mouse model of optic nerve injury, which has implications for multiple sclerosis (MS) and other diseases associated with myelin loss, a study reported.
The study, “Robust Myelination of Regenerated Axons Induced by Combined Manipulations of GPR17 and Microglia,” was published in the journal Neuron.
The hallmark of MS is the loss of the myelin sheath — a fatty protective coating surrounding the fibers, or axons, of nerve cells (neurons). Without myelin, electrical impulses traveling along axons are slower and less efficient, leading to nerve cell degeneration in the central nervous system (CNS, brain and spinal cord) and a range of disease symptoms.

NIH to investigate minor cannabinoids and terpenes for potential pain-relieving properties
Despite a lack of robust evidence, cannabinoids — such as CBD — are often assumed to be safe and effective in managing pain and used for such purposes in real-world settings. Now, nine new research awards totaling approximately $3 million will investigate the potential pain-relieving properties and mechanisms of actions of the diverse phytochemicals in cannabis, including both minor cannabinoids and terpenes. These awards, funded by the National Center for Complementary and Integrative Health (NCCIH), part of the National Institutes of Health (NIH), will strengthen the evidence regarding cannabis components and whether they have potential roles in pain management.
