The Sumoylation Of The Non-Structural Protein 1 Of The Influenza A Virus Plays A Dual Role During Viral Infection, Jason Michael Chacon
The Sumoylation Of The Non-Structural Protein 1 Of The Influenza A Virus Plays A Dual Role During Viral Infection, Jason Michael Chacon
Open Access Theses & Dissertations
The potential for a highly pathogenic influenza pandemic remains a concern for global health. The ability of the influenza virus to undergo antigenic shift and genetic drift give circulating strains of influenza the high probability of developing resistance to current antiviral therapies. Emerging strains of higher virulence, to which the infected person has not had any previous exposure to viral antigens, pose a greater threat of serious illness and death. Currently, there is no antiviral therapy that is effective against all strains of influenza, emphasizing the need to develop new strategies that target cellular systems required for viral replication to …

Sumoylation Affects Ns1'S Ability To Neutralize The Interferon Response, Jeanette Cecilia Gonzalez
Open Access Theses & Dissertations
It is of huge concern the possibility that at some point in the future we may face a new pandemic involving a highly pathogenic virus due to our current preventive and treatment options to fight this viral disease. The main reason for such limitations is the ability of the virus to go over constant antigenic shifts and drifts on its viral surface proteins HA and NA. The constant mutations that affect this virus cause the need of developing new vaccines for each influenza season. Periodically, the World Health Organization (WHO) reports that around 10% of the world population gets infected …

The Characterization Of The Interplay Between Sumoylation And Influenza A Virus, Andres Santos
Open Access Theses & Dissertations
Influenza A virus is a negative sense single stranded RNA virus responsible for multiple devastating pandemics in the past. This virus is capable of entering multiple eukaryotic hosts, sequestering, and using their cellular machinery for its own replicative purposes. This plethora of molecular events is all orchestrated through a shockingly limited repertoire of only 11 viral proteins. All of which are all strictly dependent on cellular processes such as post-transcriptional regulation, protein translation, post-translational modifications, etc. This study is focused on the characterization of the interplay between Influenza A virus and the cellular SUMOylation system. The first part of this …

Open Access Theses & Dissertations
The most important current anti-influenza weapons, vaccination and antiviral drugs, can be rapidly rendered fully ineffective thanks to the virus's high mutational rate, which produces viruses exhibiting new antigenic properties and structural proteins insensitive to the drug's mechanism of action. One attractive alternative is to develop drugs that modulate the activity of cellular systems either required for viral growth or able to neutralize viral growth. Here we demonstrate that the cellular SUMOylation system, a post-translational modification involving the conjugation of the Small Ubiquitin-like MOdifier (SUMO) to specific protein targets using a Ubiquitin-like enzymatic cascade, interacts closely with influenza virus during …
