Avian infectious bronchitis virus (IBV), a coronavirus, causes infectious bronchitis leading to enormous economic loss in the poultry industry worldwide. Hypericin (HY) is an excellent compound that has been investigated in antiviral, antineoplastic, and antidepressant. To investigate the inhibition effect of HY on IBV infection in chicken embryo kidney (CEK) cells, 3 different experimental designs: pre-treatment of cells prior to IBV infection, direct treatment of IBV-infected cells, and pre-treatment of IBV prior to cell infection were used. Quantitative real-time PCR (qRT-PCR), immunofluorescence assay (IFA), flow cytometry, and fluorescence microscopy were performed and virus titer was determined by TCID 50 . The re-sults revealed that HY had a good anti-IBV effect when HY directly treated the IBV-infected cells, and virus infectivity decreased in a dose-dependent manner. Furthermore, HY inhibited IBV-induced apoptosis in CEK cells, and significantly reduced the mRNA expression levels of Fas, FasL, JNK, Bax, Caspase 3, and Caspase 8, and significantly increased Bcl-2 mRNA expression level in CEK cells. In addition, HY treatment could decrease IBV-induced reactive oxygen species (ROS) generation in CEK cells. These results suggested that HY showed potential antiviral activities against IBV infection involving the inhibition of apoptosis and ROS generation in CEK cells.

Ex Output:
Protective effects of hypericin against infectious bronchitis virus induced apoptosis and reactive oxygen species in chicken embryo kidney cells

Ramsay Hunt syndrome (RHS) is characterized by varicella zoster virus (VZV) infection in the geniculate ganglion of the facial nerve. It typically presents with ipsilateral facial palsy and vesicles in the external auditory canal [1] . Recognizing atypical clinical manifestations of RHS, though not frequently reported, is of clinical importance for clinicians. For instance, RHS without vesicles, condition known as zoster sine herpete [2] , is difficult to distinguish itself from Bell's palsy. Although the vestibulocochlear nerve is frequently co-involved during the course of RHS, multiple lower cranial nerve involvement has rarely been described in the literature [5] [6] [7] [8] [9] [10] [11] [12] . Additionally, laryngitis due to VZV associated with RHS is not a well-recognized clinical entity. We herein report a case of Ramsay Hunt syndrome with zoster pharyngitis involving multiple lower cranial nerves. A 66-year-old woman with a history of hypertension was hospitalized because of progressive dizziness, right-side facial weakness and dysphagia. The patient was in her usual state of health until 6 days before admission, when sore throat and odynophagia developed, associated with subjective fevers and anorexia. Two days before admission, the patient reported dizziness, right-side facial weakness associated with pain radiating to the right ear, and dysphagia. The patient denied headache, photophobia, neck stiffness, nausea or vomiting. On the morning of admission, the patient developed right-side tinnitus, unsteady gait and inability to close the right eye. On physical examination, the patient appeared to be in mild distress. The temperature was 101.8 8F, blood pressure 176/93 mm Hg, pulse 102 beats per minute, respirations 20 breaths per minute and oxygen saturation 97% on room air. Her heart sounds were regular without murmurs and her lungs were clear to auscultation. On otologic examination, a few vesicles were observed in the external auditory canal of the right ear with a normal tympanic membrane. Neurological examination revealed peripheral facial nerve palsy (VII), with involvement of the left vestibulocochlear nerve (VIII), glossopharyngeal nerve (IX) and vagus nerve (X) ( Table 1) . Spinal accessory nerve (XI) and hypoglossal nerve (XII) were intact. Flexible laryngoscopic examination revealed erythema and erosive lesions on the right side of the epiglottis and arytenoid. There was an asymmetry of the soft palate. A biopsy of the erosive lesions was not performed. A non-contrast computed tomography of the head and temporal bone revealed no abnormalities. Ramsay Hunt syndrome with laryngitis due to varicella zoster virus was suspected and the patient was started on acyclovir and steroid therapy. After the completion of a 7-day course of the combination therapy, the patient's neurological symptoms improved except for the facial nerve palsy. Healed erosions on the IDCases 2 (2015) 47-48 A B S T R A C T Ramsay Hunt syndrome is characterized by varicella zoster virus infection affecting the geniculate ganglion of the facial nerve. It typically presents with vesicles in the external auditory canal associated with auricular pain and peripheral facial nerve paralysis. Although vestibulocochlear nerve is frequently co-involved during the course of Ramsay Hunt syndrome, multiple lower cranial nerve involvement has rarely been described in the literature. In addition, laryngitis due to varicella zoster virus is a diagnostic challenge due to its unfamiliarity among clinicians. We report a case of Ramsay Hunt syndrome with laryngitis involving multiple lower cranial nerves.

Seven coronaviruses (CoVs) have been isolated from humans so far. Among them, three emerging pathogenic CoVs, including severe acute respiratory syndrome coronavirus (SARS-CoV), Middle East respiratory syndrome coronavirus (MERS-CoV), and a newly identified CoV (2019-nCoV), once caused or continue to cause severe infections in humans, posing significant threats to global public health. SARS-CoV infection in humans (with about 10% case fatality rate) was first reported from China in 2002, while MERS-CoV infection in humans (with about 34.4% case fatality rate) was first reported from Saudi Arabia in June 2012. 2019-nCoV was first reported from China in December 2019, and is currently infecting more than 70000 people (with about 2.7% case fatality rate). Both SARS-CoV and MERS-CoV are zoonotic viruses, using bats as their natural reservoirs, and then transmitting through intermediate hosts, leading to human infections. Nevertheless, the intermediate host for 2019-nCoV is still under investigation and the vaccines against this new CoV have not been available. Although a variety of vaccines have been developed against infections of SARS-CoV and MERS-CoV, none of them has been approved for use in humans. In this review, we have described the structure and function of key proteins of emerging human CoVs, overviewed the current vaccine types to be developed against SARS-CoV and MERS-CoV, and summarized recent advances in subunit vaccines against these two pathogenic human CoVs. These subunit vaccines are introduced on the basis of full-length spike (S) protein, receptorbinding domain (RBD), non-RBD S protein fragments, and non-S structural proteins, and the potential factors affecting these subunit vaccines are also illustrated. Overall, this review will be helpful for rapid design and development of vaccines against the new 2019-nCoV and any future CoVs with pandemic potential. This review was written for the topic of Antivirals for Emerging Viruses: Vaccines and Therapeutics in the Virology section of Frontiers in Microbiology.
