Research Interest

The research interest in the Zeng lab is to explore the molecular mechanisms of energy homeostasis and diseases to better understand fundamental biological processes. Currently, our major direction is energy balance, including metabolic homeostasis and diseases, neural and immune regulation of metabolism and neuro-inflammation. Understanding these processes may provide key insights into the therapeutics of metabolic related diseases, including obesity, diabetes, and immunological disorders.


Topics of Research

Energy balance

 

Efferent signals from the central nervous system represent a key layer of regulation of white adipose tissue (WAT). We exploit the volume fluorescence-imaging technique to visualize the neural arborizations in mouse inguinal WAT at single-fiber resolution. The imaging reveals a dense network of sympathetic arborizations that had been previously undetected by conventional methods, with sympathetic fibers being in close apposition to > 90% of adipocytes. We demonstrate that these sympathetic fibers originate from the celiac ganglia, which are activated by cold challenge. Sympathetic-specific deletion of TrkA receptor or pharmacologic ablation by 6-hydroxydopamine abolishes these intra-adipose arborizations and, as a result, cold-induced beiging of inguinal WAT. Furthermore, we find that local sympathetic arborizations function through beta-adrenergic receptors in this beiging process. These findings uncover an essential link connecting efferent neural signals with metabolism of individual adipocytes.

Neuroinflammation

 

Neuroinflammation is a crucial mechanism in many neurological disorders. Injury to the peripheral sensory nerves leads to a neuroinflammatory response in the somatosensory pathway, from dorsal root ganglia (DRG) to the spinal cord, contributing to neuropathic pain. We find that ciliary neurotrophic factor (CNTF), highly expressed in Schwann cells, mediates neuroinflammatory response through the activating signal transducer and activator of transcription 3 (STAT3) and inducing interleukin 6 (IL-6) in sensory neurons. Cntf deficiency attenuates neuroinflammation in DRG and the spinal cord with alleviated pain post-injury. Recombinant CNTF applied to the sensory nerves recapitulates neuroinflammation in the DRG and spinal cord, with consequent pain development. We delineate the CNTF-STAT3-IL-6 axis in mediating the onset and progression of the inflammatory cascade from the periphery to the spinal cord with therapeutic implications for neuropathic pain.

We find that dual leucine zipper kinase (DLK) is required for the neuronal intrinsic immune response to induce cytokines and chemokines such as Ccl2, Ccl7, and Ccl12 upon nerve injury. The DLK-controlled injury response in sensory neurons could regulate CD11b+ immune cell infiltration in the dorsal root ganglia, as well as microgliosis and astrogliosis in the spinal dorsal horn but not the ventral horn. Deficiency of Dlk drastically alleviates the neuropathic pain elicited by chronic constriction injury of the sciatic nerve. Thus, DLK is an essential component that mediates the neuronal intrinsic immune response to nerve injury in sensory neurons and regulates inflammation in the spinal cord.
