October 28, 2015 | Progress made with novel breakthrough vaccines: new production cell lines cope with difficult to express toxic antigens
Munich, 28 October 2015, very soon will there be novel breakthrough vaccines in the market. Associating vaccines with just prophylaxis is a thought of the past, increasingly, vaccines will demonstrate therapeutic effects specifically in the field of so far difficult to address tumor diseases (immune therapies).
A critical hurdle has in the past been making enough of the vaccine vector material. This is especially difficult if not impossible when critical antigens are toxic because they are of viral or bacterial origin as is the case for HIV envelope proteins and bacterial virulence factors. This occurs in the majority of cases.more...more in German....

August 19, 2014 |Tissue specific optimized AAV Plasmids are now available to make research & therapy more targeted
Munich, 19 August 2014, viral vectors are a new class of biologics that help treat diseases caused by defective gene function / proteins (“gene therapy”). More than 20 companies worldwide the majority of which originate in the United States are applying viral vectors to conduct clinical studies.
A key hurdle when applying viral vectors is to limit the transduction (gene transfer) to the appropriate cells of a specific tissue without affecting their surrounding environment. But, how can an expression system differentiate between tissue or even cell type? SIRION Biotech, in cooperation with U of Munich (LMU) and U of Cologne, has developed a line of viral vectors with specific promotors that are only active in a specific set of targetetd cells to initiate the desired gene expression. Using this method, the gene of interest is only being expressed in the targeted tissue which is relevant for the desired therapy. This improves the effectiveness of the therapy and also addresses safety concerns by reducing the likelihood of side effects. more...
June 12, 2014 | Adenovirus Vectors meet critical FDA requirement regarding risk of contamination with infectious agents; a critical hurdle on their way to clinical studies can be overcome
SIRION Biotech has its viral vectors tested by SGS Vitrology for replication competent adenovirus (RCA)
Viral vectors present themselves as a new class of biologics that help treat diseases caused by defective genes / proteins (“gene therapy”). About 20 companies worldwide the majority of which originating in the United States are applying viral vectors to conduct clinical studies.
A key safety concern is the risk of transmission of infectious agents by inadequately tested products, specifically any replication competent adenovirus (RCA) still being administered to the patient. RCA comes from working with the most common production cell line used for replication defective adenovirus vectors, HEK293. Besides ethical concerns around HEK293, the cell line may complement the critical E1 replication gene that is lacking in the vector. The concern that RCA could lead to adverse events in patients led FDA to recommend limits on RCA levels in clinical lots of adenovirus vectors. more...
March 25, 2014 | Overcoming hurdles of HCMV vaccine development: Munich researchers claim progress
Recent patent publication introduces a viral vector that is both infecting endothelial cells and is eliciting an immune response
Munich, Infections by Human Cytomegalovirus (HCMV) are among the medically most significant herpesvirus infections. About 30 – 40.000 infants p.a. are born already infected in the USA alone, millions when including countries less developed. Individuals with a competent immune system cope with such infection, less so individuals that have experienced organ transplants or HIV. Such individuals then suffer life-threatening inflammatory diseases over and over again. The National Vaccine Committee of the US Institute of Medicine made an effective HCMV vaccine a highest level priority due to society costs in both morbidity groups.
No vaccine is commercially available, the therapy of choice is a single hit chemotherapy with known severe side effects. Searching for an effective HCMV vaccine has become a #1 priority in vaccine research.
25. März 2014 | Fortschritte bei der Entwicklung eines Zytomegalieimpfstoffs: das Patent Münchner Forscher ist publiziert
Die jüngste Veröffentlichung eines Patents beschreibt einen viralen Vektor, der zugleich Endothelzellen der innersten Wandschicht befällt und die gewünschte Immunantwort auslöst.
München, Infektionen des humanen Zytomegalievirus (HCMV) gehören zu den medizinisch bedeutendsten Infektionen des Herpesvirus. Etwa 30 – 40.000 Neugeborene im Jahr allein in USA sind hiermit infiziert, Millionen bei Einbeziehung der weniger entwickelten Welt. Menschen mit einem gut ausgeprägten Immunsystem wehren eine solche Infektion ab, Menschen mit HIV oder Organtransplantationen weniger. Solche Menschen leiden immer wieder an lebensbedrohenden Entzündungskrankheiten. Das Nationale Impfstoffkomitee des Amerikanischen Institute of Medicine hat der Entwicklung eines wirksamen Impfstoffs gegen HCMV oberste Priorität eingeräumt.
March 20, 2014 | Human Taste Sensation can now be investigated on a molecular level with stably proliferating Human Taste Cells
SIRION Biotech provides adenovirus to transduce proliferating-promoting genes to viable human taste cells from fungiform papillae
Munich,Chemical Senses by Oxford University Press posted a publication this week regarding stably proliferating taste bud cell lines for the study of the molecular mechanism of taste sensation. Researchers from near Frankfurt and Munich identified HTC-8 cells expressing bitter taste receptor genes. Bitter tastants triggered functionally distinct signaling pathways in such HTC-8 cells. SIRION Biotech was critical in generating adenovirus that helped transducing human taste cells such that they proliferate and maintain taste cell-specific properties and authentic responsiveness to taste stimuli.
