Lee JM, Choi YJ, Yoo MC, Yeo SG. Central Facial Nervous System Biomolecules Involved in Peripheral Facial Nerve Injury Responses and Potential Therapeutic Strategies. Antioxidants (Basel) 2023; 12:antiox12051036. [PMID: 37237902 DOI: 10.3390/antiox12051036] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/23/2023] [Revised: 04/20/2023] [Accepted: 04/29/2023] [Indexed: 05/28/2023] Open
Abstract
Peripheral facial nerve injury leads to changes in the expression of various neuroactive substances that affect nerve cell damage, survival, growth, and regeneration. In the case of peripheral facial nerve damage, the injury directly affects the peripheral nerves and induces changes in the central nervous system (CNS) through various factors, but the substances involved in these changes in the CNS are not well understood. The objective of this review is to investigate the biomolecules involved in peripheral facial nerve damage so as to gain insight into the mechanisms and limitations of targeting the CNS after such damage and identify potential facial nerve treatment strategies. To this end, we searched PubMed using keywords and exclusion criteria and selected 29 eligible experimental studies. Our analysis summarizes basic experimental studies on changes in the CNS following peripheral facial nerve damage, focusing on biomolecules that increase or decrease in the CNS and/or those involved in the damage, and reviews various approaches for treating facial nerve injury. By establishing the biomolecules in the CNS that change after peripheral nerve damage, we can expect to identify factors that play an important role in functional recovery from facial nerve damage. Accordingly, this review could represent a significant step toward developing treatment strategies for peripheral facial palsy.

Abstract
Herpes simplex virus type 1 (HSV-1) results in the development of Bell's pals but still, the pathophysiology of the facial nerve paralysis is still not fully studied. The main objective is to establish an animal model of type 1 herpes simplex virus (HSV-1)-induced face paralysis in the mouse and to investigate the pattern of changes in intercellular adhesion molecule -1(ICAM-1) expression in the facial nucleus of the brain stem in mice with facial paralysis as well as the effects of glucocorticoids on intercellular adhesion molecule -1(ICAM-1) expression. A total of 170 4-week-old Balb/c male mice were randomly divided into the virus inoculation group (n = 135), saline control group (n = 26), and blank control group (n = 9). Mice in the virus inoculation group that showed facial paralysis were divided into A, B, and C subgroups. The A group did not receive any treatments, the B group received methylprednisolone sodium succinate (MPSS) intervention, and the C group received MPSS + RU486 treatment. The mouse model of facial paralysis was established by inoculating HSV-1 to the skin at the back of the ears. The facial nerve function of mice was assessed, and real-time PCR and western blot were used to assess ICAM-1 expression in the facial nucleus of the brain stem in mice with facial paralysis after drug intervention. In the virus inoculation group, 95 mice (55.88%) showed varying degrees of facial paralysis symptoms within 2-5 days after inoculation. The ICAM-1 gene and protein expression levels remained at low levels in the facial nucleus of the brain stem of mice in the saline group, which showed no significant difference compared to the normal control group (P > 0.05). However, for mice of the virus inoculation group, ICAM-1 expression increased at 6 h after the occurrence of facial paralysis and peaked after 2 days, differing significantly from the blank control group (P < 0.01). ICAM-1 expression subsequently decreased gradually. In the HSV-1 + MPSS group, ICAM-1 protein expression decreased significantly on the 2nd day after facial paralysis. In the HSV-1 + MPSS + RU486 group, MPSS inhibition of ICAM-1 protein expression was reduced. The results suggested that ICAM-1 is involved in the pathological processes by which HSV-1 induces facial paralysis in mice, and the treatment effects of MPSS for Bell's palsy can be achieved by the inhibition of MCP-1.

Abstract
It has been documented that infection of herpes simplex virus type 1 (HSV-1) contributes to the initiation of Bell's palsy. However, the exact mechanisms responsible for this disorder have not been fully elucidated to date. A mouse model of facial palsy induced by HSV-1 provides an opportunity to investigate the alteration in activities of nuclear factor-kappa B (NF-κB) and its consequent effect on two key inflammatory factors, i.e., tumor necrosis factor (TNF)-α and cyclooxygenase-2 (COX-2), as well as the effect of glucocorticoids (GCs) in this work. I-kappa B (IκB)-α phosphorylation and NF-κB nuclear translocation were measured by western blotting, and NF-κB/DNA binding activity was assessed by electrophoretic mobility shift assay (EMSA). Results showed the IκB-α phosphorylation and degradation as well as NF-κB activation in a time-dependent manner. The expression of TNF-α and COX-2 were determined by real-time polymerase chain reaction (PCR), western blotting and/or enzyme-linked immunosorbent assay (ELISA) respectively. Concomitant with the activation, the expression and secretion of TNF-α and COX-2 were rapidly induced in HSV-1-infected paralyzed mice. Conversely, the activation of NF-κB and up-regulation of TNF-α and COX-2 were blocked by pretreatment with NF-κB inhibitor pyrrolidine dithiocarbamate (PDTC) before being inoculated with HSV-1 to mice. In addition, GCs inhibited the nuclear translocation and DNA binding activity of NF-κB via inhibiting IκB-α degradation. Meanwhile, TNF-α production and COX-2 expression were significantly reduced by GCs. In conclusion, HSV-1 inoculation induced the activation of NF-κB, expression and secretion of TNF-α and COX-2 in the facial paralyzed mice, while, glucocorticoid effectively down-regulated TNF-α and COX-2 expression in HSV-1-induced paralyzed mice.

Abstract
Bell's palsy presents a unilateral weakness or paralysis of the face due to acute dysfunction of the peripheral facial nerve with no readily identifiable cause. Although data show that herpes simplex virus type 1 (HSV-1) may be the possible causative agent of Bell's palsy, the precise mechanism of the paralysis is still unknown. SHANK-associated RH domain-interacting protein (SHARPIN) is thought to play a role in the control of inflammatory responses. In order to clarify the molecular pathway of SHARPIN involved in the facial palsy caused by HSV-1 in mice and the inhibitory effect of corticosteroids, we used 4-week-old Balb/c mice inoculated with HSV-1 for experiments. The expression and location of SHARPIN in the facial nucleus of brainstem were detected respectively by quantitative real-time polymerase chain reaction, western blot and immunofluorescence. Expression level of SHARPIN increased and peaked at 2 days and then decreased in the facial nucleus of brainstem after the manifestation of the facial paralysis. After the administration of MPSS, the protein expression of SHARPIN at the peak point was down-regulated. Our results suggest that SHRPIN were activated during the inflammatory reaction in the HSV-1-induced facial paralysis. MPSS can effectively inhibit the expression of SHARPIN that may contribute to attenuate HSV-1-mediated nervous system damage.

Abstract
OBJECTIVE Herpes simplex virus 1 (HSV-1) is regarded as an important underlying cause of Bell's palsy, but the immunologic mechanism remains unknown. Here, we employed a mouse facial paralysis model to investigate the expressions of CD4(+) T lymphocytes and interleukin (IL)-2 and -4 in the left draining cervical lymph nodes (LCLN) and spleen, as well as the inhibitory effects of glucocorticoids (GCs). METHODS HSV-1 was inoculated into the surface of the posterior auricle to generate the facial paralysis model. The paralyzed mice were divided into three groups; in one group without any treatment, mice were killed at different time points, and those in the other two groups were injected with methylprednisolone sodium succinate (MPSS) or with a combination of MPSS and GC receptor blocker (RU486). The expression levels of CD4(+) T lymphocytes and CD4(+)-IL-2(+) and CD4(+)-IL-4(+) cells in the LCLN and spleen were detected by fluorescence-activated cell sorting. RESULTS Expression levels of CD4(+), IL-2, and IL-4 first increased then decreased in LCLN and spleen and peaked 5 and 7 days, respectively, after the manifestation of facial paralysis. All the data at the peak points were significantly different compared with control (p < 0.05), and these effects were inhibited by MPSS. CONCLUSION Our results suggest that CD4(+), IL-2, and IL-4 participate in the HSV-1-induced facial paralysis immune response. MPSS can effectively attenuate HSV-1-mediated nervous system damage, which is associated with its inhibitory effect on expression of these inflammatory markers.

Abstract
The aim of this study is to explore the changes of matrix metalloproteinase-9 (MMP9) in the mouse brainstem during the development of facial paralysis induced by herpes simplex virus type 1 (HSV-1) and the inhibitory effect of methylprednisolone sodium succinate (MPSS) on MMP9 expression. HSV-1 was inoculated into the surface of posterior auricle of mouse to establish a paralyzed animal model. The paralyzed mice were divided randomly into three groups. In one group without any treatment, mice were killed at different time points of 6 h, 1, 2, 3, and 7 days post-induction of facial paralysis; in the other two groups, mice were injected daily with MPSS and a combination of MPSS and glucocorticoid receptor blocker (RU486) for 2 days, respectively. The expression of MMP9 in the facial nucleus of brainstem was detected by Western blot, quantitative real-time polymerase chain reaction, and immunofluorescence technique. A total of 52.07 % of mice developed unilateral facial paralysis after inoculated with HSV-1. Both mRNA and protein expression of MMP9 were present at low levels in normal facial nucleus of brainstem and were increased significantly after facial paralysis with its peak time at 2 days post-induction of facial paralysis. Expression of MMP9 of paralyzed mice was inhibited by MPSS, and the inhibition could be blocked by RU486. Our findings suggest that MMP9 in mouse brainstem is involved in the evolution of facial palsy induced by HSV-1 and may play an important role in the pathogenesis of this disease. MPSS might effectively relieve HSV-1-mediated damages by inhibitory effect on expression of MMP9 in HSV-1-induced facial paralysis.
