CERE-120 Prevents Irradiation-Induced Hypofunction and Restores Immune Homeostasis in Porcine Salivary Glands. MOLECULAR THERAPY-METHODS & CLINICAL DEVELOPMENT 2020; 18:839-855. [PMID: 32953934 PMCID: PMC7479444 DOI: 10.1016/j.omtm.2020.07.016] [Citation(s) in RCA: 13] [Impact Index Per Article: 3.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 03/07/2020] [Accepted: 07/27/2020] [Indexed: 02/07/2023]
Abstract
Salivary gland hypofunction causes significant morbidity and loss of quality of life for head and neck cancer patients treated with radiotherapy. Preventing hypofunction is an unmet therapeutic need. We used an adeno-associated virus serotype 2 (AAV2) vector expressing the human neurotrophic factor neurturin (CERE-120) to treat murine submandibular glands either pre- or post-irradiation (IR). Treatment with CERE-120 pre-IR, not post-IR, prevented hypofunction. RNA sequencing (RNA-seq) analysis showed reduced gene expression associated with fibrosis and the innate and humoral immune responses. We then used a minipig model with CERE-120 treatment pre-IR and also compared outcomes of the contralateral non-IR gland. Analysis of gene expression, morphology, and immunostaining showed reduced IR-related immune responses and improved secretory mechanisms. CERE-120 prevented IR-induced hypofunction and restored immune homeostasis, and there was a coordinated contralateral gland response to either damage or treatment. CERE-120 gene therapy is a potential treatment for head and neck cancer patients to influence communication among neuronal, immune, and epithelial cells to prevent IR-induced salivary hypofunction and restore immune homeostasis.

Delivery of human erythropoietin gene with an adeno-associated virus vector through parotid glands to treat renal anaemia in a swine model. Gene Ther 2017; 24:692-698. [PMID: 28753201 DOI: 10.1038/gt.2017.70] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/11/2017] [Revised: 07/20/2017] [Accepted: 07/21/2017] [Indexed: 12/18/2022]
Abstract
Anaemia is a common complication of chronic kidney disease, for which there is presently no adequate treatment. The delivery of human erythropoietin (hEPO) cDNA to salivary glands reportedly increases red blood cell counts, haematocrit (HCT) and haemoglobin concentration, representing a potential new method of renal anaemia treatment. However, no studies have examined the effects of this method in an animal model of renal anaemia. Here we established a miniature pig animal model of renal anaemia through continuous feeding with adenine. In these animals, we delivered the AAV2hEPO gene to the parotid glands through Stensen's duct. As a control, we transferred AAVLacZ. Enzyme-linked immunosorbent assay was used to detect hEPO in serum and saliva. Red blood counts and serum biochemistry were used to evaluate how hEPO gene administration affected renal anaemia. Compared with the control group, we found increased hEPO concentrations in parotid saliva and serum, respectively, at 2 and 6 weeks after AAV2hEPO administration to the anaemic animals. HCT and haemoglobin were also increased after AAV2hEPO was delivered; most serum indicators of renal damage were not changed over the time span of the experiment, suggesting the adenine-induced kidney damage had not been completely reversed. However, blood urea nitrogen and B2 microglobulin levels showed small but significant improvement. Overall, our present findings suggest that adeno-associated virus 2 (AAV2)-mediated gene transduction of hEPO via the parotid gland is a promising potential alternative therapy for renal anaemia.

Abstract
Background: Low-level, chronic viral infections have been suspect in the development of select autoimmune diseases, including primary Sjögren's syndrome (pSS). Multiple studies have shown stimulation of antiviral response pathways in pSS tissues suggestive of a viral infection. Yet, with this data in hand, a causal link between a viral infection and development of pSS had not been identified. Therefore, a study was designed to further define the viral landscape within pSS-affected salivary gland tissue to identify potential viral-mediated triggers in the pathogenesis of this autoimmune disease. Methods: A viral microarray was utilized to measure viral transcripts present in salivary gland tissue from patients diagnosed with pSS compared to healthy controls. Murine models of salivary gland localized HDV antigen expression were developed to evaluate the capacity of a chronic HDV signature to trigger the development of a pSS-like phenotype. Results: Through this analysis, two distinct viral profiles were identified, including the increased presence of hepatitis delta virus (HDV) in 50% of pSS patients evaluated. Presence of HDV antigen and sequence were confirmed in minor salivary gland tissue. Patients with elevated HDV levels in salivary gland tissue were negative for detectible hepatitis B virus (HBV) surface antigen and antibodies to HBV or HDV. Expression of HDV antigens in vivo resulted in reduced stimulated saliva flow, increase in focal lymphocytic infiltrates, and development of autoantibodies. Conclusion: Identification of HDV in pSS patients and induction of a complete pSS-like phenotype in vivo provides further support of a viral-mediated etiopathology in the development of pSS.

Plasmid DNA is internalized from the apical plasma membrane of the salivary gland epithelium in live animals. Histochem Cell Biol 2012; 138:201-13. [PMID: 22544351 DOI: 10.1007/s00418-012-0959-7] [Citation(s) in RCA: 14] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Accepted: 04/13/2012] [Indexed: 10/28/2022]
Abstract
Non-viral-mediated gene delivery represents an alternative way to express the gene of interest without inducing immune responses or other adverse effects. Understanding the mechanisms by which plasmid DNAs are delivered to the proper target in vivo is a fundamental issue that needs to be addressed in order to design more effective strategies for gene therapy. As a model system, we have used the submandibular salivary glands in live rats and we have recently shown that reporter transgenes can be expressed in different cell populations of the glandular epithelium, depending on the modality of administration of plasmid DNA. Here, by using a combination of immunofluorescence and intravital microscopy, we have explored the relationship between the pattern of transgenes expression and the internalization of plasmid DNA. We found that plasmid DNA is internalized: (1) by all the cells in the salivary gland epithelium, when administered alone, (2) by large ducts, when mixed with empty adenoviral particles, and (3) by acinar cells upon stimulation of compensatory endocytosis. Moreover, we showed that plasmid DNA utilizes different routes of internalization, and evades both the lysosomal degradative pathway and the retrograde pathway towards the Golgi apparatus. This study clearly shows that in vivo approaches have the potential to address fundamental questions on the cellular mechanisms regulating gene delivery.
