Abstract
Uveal melanoma (UM), the most common primary malignant tumor of the eye in adults, is difficult-to-treat. UM has a relatively high mortality secondary to distant metastasis and poor overall survival with existing therapies. The oncolytic virus herpes simplex virus type-1 (HSV-1) has been approved for clinical use in melanoma. This double-stranded DNA virus was suspected to directly activate lysis specifically in neoplastic cells. We tested the antitumor efficacy of recombinant oncolytic HSV-1-EGFP (oHSV-EGFP) in UM and characterized the local and systemic antitumor innate immune response in a murine xenograft model. We first determined the efficacy of the oncolytic virus in 92.1, MUM2B and MP41 cell lines. In murine xenograft models, oHSV-EGFP reduced intraocular tumors as well as systemic subcutaneous tumors. A significant change in cytokines was observed in viral infected cells, especially a rise in IFNγ. In vivo analyses showed increased anti-tumorigenic M1 macrophages and decreased pro-tumorigenic M2 macrophages in peripheral blood, and intraocular and distant tumors after intravitreal viral treatment. Increased infiltration of natural killer cells and mature dendritic cells was also detected after viral treatment. In addition, no virus was detected in major organs after the treatment. Our data support that oHSV-EGFP is effective, neoplasm specific, immune active and safe, providing possible clinical translatable options to treat ocular and metastatic UM.

Abstract
Purpose: To assess the immune status of acute retinal necrosis (ARN) patients and to investigate the immune cell types involved in the immunopathogenesis.Methods: Peripheral blood and intraocular fluid were collected from 17 ARN patients and 9 control subjects. The Percentage of immune cells was measured using flow cytometry, levels of complement and antibodies were determined by rate nephelometry, and cytokine levels in the serum and aqueous humor (AH) were detected using cytokine quantitative chips. Data were analyzed using SPSS 23.0. p < .05 was considered statistically significant.Results: Proportion of T-helper 17 cells (p = .034) in serum and concentrations of multiple cytokines associated with Th17 cells (IL-6, IL-17, IL-17 F, IL-21, IL-22) in AH and serum were elevated of ARN patients.Conclusion: Th17 cells appeared to participate in the development of ARN. We found inflammatory cytokines and cells were elevated in the serum and AH of ARN patients.

Intravitreal treatment with antisense oligonucleotides targeting tumor necrosis factor-α in murine herpes simplex virus type 1 retinitis. Graefes Arch Clin Exp Ophthalmol 2011; 250:231-8.

Abstract
BACKGROUND Tumor necrosis factor alpha (TNF-α) is a proinflammatory cytokine known to participate in intraocular inflammatory disease. This study investigated whether treatment with intravitreal antisense-oligonucleotides (ASON) targeting TNF-α mRNA affects the progression of herpes simplex virus 1 (HSV-1) retinitis in mice. METHODS The in vivo uptake of the oligonucleotid after intravitreal injection was determined with FITC-labeled TNF-α ASON. HSV-retinitis was induced on day 0 by the injection of HSV-1 (KOS strain) into the anterior chamber (AC) of the right eyes of BALB/c mice (von Szily model). The left contralateral eyes were injected intravitreally on day 7 with TNF-α ASON, sequence-unspecific control ASON (CON), or buffer. The clinical course of retinitis, ocular inflammatory cell-infiltration, TNF-α expression in the eye by ELISA, delayed-type hypersensitivity (DTH) reaction, virus-neutralizing antibody titers in the serum, uptake of [3H]thymidine from regional lymph node (rln) cells, and viral content in the eyes were determined. RESULTS In vivo, strong fluorescence of FITC- TNF-α ASON was detected in the choroid and retina up to 3 days after intravitreal injection, but none in the rln. After treatment of eyes with ASON, decreased expression of TNF-α in the eye, and reduced incidence and severity of retinitis on day 10 after infection (P < 0.05) could be found. The other parameters were not significantly influenced after TNF-α ASON treatment. CONCLUSIONS TNF-α participates in the pathology of HSV-1 retinitis. Local inhibition of TNF-α mRNA by intraocular TNF-α ASON injection did not influence the systemic HSV-specific immune response or the antiviral response in the eye, but reduced ocular inflammatory bystander damage.

Abstract
PURPOSE After uniocular anterior chamber (AC) injection of HSV-1, the anterior segment of BALB/c mice becomes inflamed and infected; however, virus does not spread from the anterior segment to cause retinitis in the injected eye. The purpose of these studies was to determine whether interferon (IFN-)-γ and Mac-1(+) cells play a role in preventing direct anterior-to-posterior spread of HSV-1 in the injected eye. METHODS One AC of adult female BALB/c mice was injected with HSV-1 (KOS). The location of IFN-α, IFN-β, and IFN-γ in the injected eye was determined by immunofluorescence, and mRNA expression was quantified by qPCR. Injected eyes of IFN-γ knockout or clodronate-treated macrophage-depleted mice were examined to determine whether the absence of IFN-γ or Mac-1(+) macrophages affected the sites or timing of virus spread. RESULTS IFN-α, IFN-β, and IFN-γ were observed in the anterior segment of injected eyes through 72 hours and mRNA levels of IFN-β and IFN-γ were increased in virus-infected eyes 48 to 120 hours after infection. However, the absence of IFN-γ or macrophages did not affect either the sites or the timing of HSV-1 infection in injected eyes. CONCLUSIONS Protection of the retina of the injected eye does not depend on a single cell type or cytokine. In addition, in the eye, as in other sites of the body, there are redundancies in the innate response to virus infection.

The Role of Plasmacytoid Dendritic Cells in Innate and Adaptive Immune Responses against Alpha Herpes Virus Infections. Adv Virol 2011; 2011:679271. [PMID: 22312349 PMCID: PMC3265311 DOI: 10.1155/2011/679271] [Citation(s) in RCA: 10] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/23/2010] [Accepted: 02/02/2011] [Indexed: 12/18/2022] Open
Abstract
In 1999, two independent groups identified plasmacytoid dendritic cells (PDC) as major type I interferon- (IFN-) producing cells in the blood. Since then, evidence is accumulating that PDC are a multifunctional cell population effectively coordinating innate and adaptive immune responses. This paper focuses on the role of different immune cells and their interactions in the surveillance of alpha herpes virus infections, summarizes current knowledge on PDC surface receptors and their role in direct cell-cell contacts, and develops a risk factor model for the clinical implications of herpes simplex and varicella zoster virus reactivation. Data from studies involving knockout mice and cell-depletion experiments as well as human studies converge into a "spider web", in which the direct and indirect crosstalk between many cell populations tightly controls acute, latent, and recurrent alpha herpes virus infections. Notably, cells involved in innate immune regulations appear to shape adaptive immune responses more extensively than previously thought.
