Chitosan Tubes Inoculated with Dental Pulp Stem Cells and Stem Cell Factor Enhance Facial Nerve-Vascularized Regeneration in Rabbits.

ACS Omega 2022 Jun 26;7(22):18509-18520. Epub 2022 May 26.

Department of Materials Science and Engineering, State Key Laboratory of New Ceramics and Fine Processing, Tsinghua University, Beijing 100084, China.

Facial nerve injury is a common clinical condition that leads to disfigurement and emotional distress in the affected individuals, and the recovery presents clinical challenges. Tissue engineering is the standard method to repair nerve defects. However, nerve regeneration is still not satisfactory because of poor neovascularization after implantation, especially for the long-segment nerve defects. Read More

Delivery of Basic Fibroblast Growth Factor Through an Forming Smart Hydrogel Activates Autophagy in Schwann Cells and Improves Facial Nerves Generation the PAK-1 Signaling Pathway.

Front Pharmacol 2022 1;13:778680. Epub 2022 Apr 1.

Department of Otorhinolaryngology, The Second Affiliated Hospital and Yuying Children's Hospital of Wenzhou Medical University, Wenzhou, China.

Although studies have shown that basic fibroblast growth factor (bFGF) can activate autophagy and promote peripheral nerve repair, the role and the molecular mechanism of action of bFGF in the facial nerve are not clear. In this study, a thermosensitive forming poloxamer hydrogel was used as a vehicle to deliver bFGF for treating facial nerve injury (FNI) in the rat model. Using H&E and Masson's staining, we found that bFGF hydrogel can promote the functional recovery and regeneration of the facial nerve. Read More

Psychol Health Med 2022 Mar 8:1-12. Epub 2022 Mar 8.

Department of Biomedical Engineering, Chengde Medical University, Chengde, Hebei, China.

Compared with their younger counterparts, older adults are inclined to allocate more attentional resources to positive over negative materials. This age-related positivity effect has been reported in various experimental paradigms; however, studies have not investigated the attention stage at which it appears or its potential neural mechanism. Thus, we investigated the time and frequency domain dynamics of younger and older adults during emotional attention processes. Read More

Overexpression of c-Jun inhibits erastin-induced ferroptosis in Schwann cells and promotes repair of facial nerve function.

J Cell Mol Med 2022 04 22;26(8):2191-2204. Epub 2022 Feb 22.

Department of Otorhinolaryngology-Head and Neck Surgery, Xinhua Hospital, Shanghai Jiaotong University School of Medicine, Shanghai, China.

Myelin undergoes various changes after nerve injury, and c-Jun has a close relationship with Schwann cells (SCs). However, it remains unclear whether c-Jun can be involved in nerve repair by regulating ferroptosis. To explore this, we first set up a facial nerve injury model and detected the changes of ferroptosis-related proteins and c-Jun by immunofluorescence and Western blot. Read More

Muscle-Nerve-Nerve Grafting Improves Facial Reanimation in Rats Following Facial Nerve Injury.

Front Neurol 2021 8;12:723024. Epub 2021 Dec 8.

Department of Otolaryngology-Head and Neck Surgery, Loyola University of Chicago, Maywood, IL, United States.

Nerve injury resulting in muscle paralysis from trauma or surgery is a major medical problem. Repair of such injuries with existing nerve grafting and reconstructive techniques often results in less than optimal outcomes. After previously demonstrating significant return of function using muscle-nerve-muscle (MNM) grafting in a rat facial nerve model, this study compares a variant of the technique, muscle-nerve-nerve (MNN) neurotization to MNM and interposition (IP) nerve grafting.

Controlled release of ciliary neurotrophic factor from bioactive nerve grafts promotes nerve regeneration in rats with facial nerve injuries.

J Biomed Mater Res A 2022 04 18;110(4):788-796. Epub 2021 Nov 18.

Department of Neurosurgery, Shanghai Ninth People's Hospital, Shanghai Jiao Tong University School of Medicine, Shanghai, China.

It is critical to repair severed facial nerves, as lack of treatment may cause long-term motor and sensory impairments. Ciliary neurotrophic factor (CNTF) plays an important role in terms of enhancing nerve axon regrowth and maturation during peripheral nerve regeneration after injury. However, simple application of CNTF to the transected nerve site does not afford functional recovery, because it is rapidly flushed away by bodily fluids. Read More

The differentiation state of the Schwann cell progenitor drives phenotypic variation between two contagious cancers.

PLoS Pathog 2021 11 15;17(11):e1010033. Epub 2021 Nov 15.

School of Biological Sciences, University of Southampton, Southampton, United Kingdom.

Contagious cancers are a rare pathogenic phenomenon in which cancer cells gain the ability to spread between genetically distinct hosts. Nine examples have been identified across marine bivalves, dogs and Tasmanian devils, but the Tasmanian devil is the only mammalian species known to have given rise to two distinct lineages of contagious cancer, termed Devil Facial Tumour 1 (DFT1) and 2 (DFT2). Remarkably, DFT1 and DFT2 arose independently from the same cell type, a Schwann cell, and while their ultra-structural features are highly similar they exhibit variation in their mutational signatures and infection dynamics.

J Hand Surg Am 2021 Nov 11. Epub 2021 Nov 11.

Division of Plastic and Reconstructive Surgery, Stony Brook University Hospital, Stony Brook Medicine, Stony Brook, NY; Department of Orthopaedic Surgery, Stony Brook University Hospital, Stony Brook Medicine, Stony Brook, NY. Electronic address:

Purpose: Brachial plexus injuries (BPI) with complete root avulsions remains a clinical challenge due to a paucity of nerves available for nerve transfer and innervation of free functioning muscle transfers (FFMT). The hypoglossal and hemihypoglossal nerve has not been studied as a donor nerve option for FFMTs in brachial plexus reconstruction, despite successful outcomes of hypoglossal nerve transfers in facial reanimation surgery. We hypothesized that the hypoglossal nerve could be an appropriate candidate for surgical repair of BPI using FFMT. Read More

Laboratory for Regeneration of Sensorimotor Systems, The Netherlands Institute for Neuroscience, Royal Netherlands Academy of Arts and Sciences (KNAW), Meibergdreef 47, Amsterdam 1105BA, The Netherlands.

The regeneration-associated gene (RAG) expression program is activated in injured peripheral neurons after axotomy and enables long-distance axon re-growth. Over 1000 genes are regulated, and many transcription factors are upregulated or activated as part of this response. However, a detailed picture of how RAG expression is regulated is lacking.

Ann Plast Surg 2022 03;88(3):308-312

Department of Plastic Surgery, University of Tennessee Health Science Center (UTHSC), Memphis, TN.

Abstract: Direct neurotization is a method that involves direct implantation of nerve fascicles into a target tissue, that is, muscle fibers, skin, cornea, and so on, with the goal of restoring aesthetic, sensation and or functional capacity. This technique has been implemented since the early 1900s, with numerous experimental and clinical reports of success.
