A Critical Role for DLK and LZK in Axonal Repair in the Mammalian Spinal Cord.

J Neurosci 2022 05 31;42(18):3716-3732. Epub 2022 Mar 31.

Department of Neurosciences, School of Medicine

The limited ability for axonal repair after spinal cord injury underlies long-term functional impairment. Dual leucine-zipper kinase [DLK; MAP kinase kinase kinase 12; MAP3K12] is an evolutionarily conserved MAP3K implicated in neuronal injury signaling from to mammals. However, whether DLK or its close homolog leucine zipper kinase (LZK; MAP3K13) regulates axonal repair in the mammalian spinal cord remains unknown. Read More

Palmitoylation couples the kinases DLK and JNK3 to facilitate prodegenerative axon-to-soma signaling.

Sci Signal 2022 03 29;15(727):eabh2674. Epub 2022 Mar 29.

Shriners Hospitals Pediatric Research Center (Center for Neurorehabilitation and Neural Repair), Lewis Katz School of Medicine at Temple University, 3500 N. Broad Street, Philadelphia, PA 19140, USA.

Dual leucine-zipper kinase (DLK; a MAP3K) mediates neuronal responses to diverse injuries and insults through the c-Jun N-terminal kinase (JNK) family of mitogen-activated protein kinases (MAPKs). Here, we identified two ways through which DLK is coupled to the neural-specific isoform JNK3 to control prodegenerative signaling. JNK3 catalyzed positive feedback phosphorylation of DLK that further activated DLK and locked the DLK-JNK3 module in a highly active state. Read More

Cellular Neuroscience, Neurodegeneration, Repair, Departments of Neurology and of Neuroscience, Yale University School of Medicine, New Haven, CT 06536, USA. Electronic address:

Adult mammalian central nervous system (CNS) trauma interrupts neural networks and, because axonal regeneration is minimal, neurological deficits persist. Repair via axonal growth is limited by extracellular inhibitors and cell-autonomous factors. Based on results from a screen in vitro, we evaluate nearly 400 genes through a large-scale in vivo regeneration screen. Read More

Bach1 promotes muscle regeneration through repressing Smad-mediated inhibition of myoblast differentiation.

PLoS One 2020 10;15(8):e0236781. Epub 2020 Aug 10.

Department of Biochemistry, Tohoku University Graduate School of Medicine, Sendai, Miyagi, Japan.

It has been reported that Bach1-deficient mice show reduced tissue injuries in diverse disease models due to increased expression of heme oxygenase-1 (HO-1)that possesses an antioxidant function. In contrast, we found that Bach1 deficiency in mice exacerbated skeletal muscle injury induced by cardiotoxin. Inhibition of Bach1 expression in C2C12 myoblast cells using RNA interference resulted in reduced proliferation, myotube formation, and myogenin expression compared with control cells. Read More

Deletion of Calcineurin in Schwann Cells Does Not Affect Developmental Myelination, But Reduces Autophagy and Delays Myelin Clearance after Peripheral Nerve Injury.

J Neurosci 2020 08 8;40(32):6165-6176. Epub 2020 Jul 8.

Hunter James Kelly Research Institute.

In the PNS, myelination occurs postnatally when Schwann cells (SCs) contact axons. Axonal factors, such as Neuregulin-1 Type III, trigger promyelinating signals that upregulate myelin genes. Neuregulin-1 Type III has been proposed to activate calcineurin signaling in immature SCs to initiate differentiation and myelination. Read More

A R inhibition in alleviating spatial recognition memory impairment after TBI is associated with improvement in autophagic flux in RSC.

J Cell Mol Med 2020 06 12;24(12):7000-7014. Epub 2020 May 12.

State Key Laboratory of Trauma, Burn, and Combined Injury, Department of Occupational Disease, Daping Hospital, Army Medical University, Chongqing, China.

Spatial recognition memory impairment is an important complication after traumatic brain injury (TBI). We previously found that spatial recognition memory impairment can be alleviated in adenosine A receptor knockout (A R KO) mice after TBI, but the mechanism remains unclear. In the current study, we used manganese-enhanced magnetic resonance imaging and the Y-maze test to determine whether the electrical activity of neurons in the retrosplenial cortex (RSC) was reduced and spatial recognition memory was impaired in wild-type (WT) mice after moderate TBI.

Targeted disruption of dual leucine zipper kinase and leucine zipper kinase promotes neuronal survival in a model of diffuse traumatic brain injury.

Mol Neurodegener 2019 11 27;14(1):44. Epub 2019 Nov 27.

Department of Neurology, The Johns Hopkins University School of Medicine, Baltimore, MD, 21205, USA.

Background: Traumatic brain injury (TBI) is a major cause of CNS neurodegeneration and has no disease-altering therapies. It is commonly associated with a specific type of biomechanical disruption of the axon called traumatic axonal injury (TAI), which often leads to axonal and sometimes perikaryal degeneration of CNS neurons. We have previously used genome-scale, arrayed RNA interference-based screens in primary mouse retinal ganglion cells (RGCs) to identify a pair of related kinases, dual leucine zipper kinase (DLK) and leucine zipper kinase (LZK) that are key mediators of cell death in response to simple axotomy.

Wallerian degeneration as a therapeutic target in traumatic brain injury.

Curr Opin Neurol 2019 12;32(6):786-795

Department of Pathology, Division of Neuropathology.

Purpose Of Review: Diffuse or traumatic axonal injury is one of the principal pathologies encountered in traumatic brain injury (TBI) and the resulting axonal loss, disconnection, and brain atrophy contribute significantly to clinical morbidity and disability. The seminal discovery of the slow Wallerian degeneration mice (Wld) in which transected axons do not degenerate but survive and function independently for weeks has transformed concepts on axonal biology and raised hopes that axonopathies may be amenable to specific therapeutic interventions. Here we review mechanisms of axonal degeneration and also describe how these mechanisms may inform biological therapies of traumatic axonopathy in the context of TBI. Read More

Multitasking: Dual Leucine Zipper-Bearing Kinases in Neuronal Development and Stress Management.

Annu Rev Cell Dev Biol 2019 10;35:501-521

Department of Neurosciences, School of Medicine, University of California, San Diego, La Jolla, California 92093, USA; email:

The dual leucine zipper-bearing kinase (DLK) and leucine zipper-bearing kinase (LZK) are evolutionarily conserved MAPKKKs of the mixed-lineage kinase family. Acting upstream of stress-responsive JNK and p38 MAP kinases, DLK and LZK have emerged as central players in neuronal responses to a variety of acute and traumatic injuries. Recent studies also implicate their function in astrocytes, microglia, and other nonneuronal cells, reflecting their expanding roles in the multicellular response to injury and in disease. Read More
