Janssen, Riny, Krogfelt, Karen A., Cawthraw, Shaun A., Pelt, Wilfrid Van, Wagenaar, J.A., Owen, Robert J.

Campylobacter is a major cause of acute bacterial diarrhea in humans worldwide (3). The incidence of human campylobacteriosis increased exponentially during the last decade of the 20th century (183),...

Influence of amino acids of a carrier protein flanking an inserted T cell determinant on T cell stimulation (1994)

Janssen, Riny, Wauben, Marca, Der Zee, Ruurd Van, De Gast, Manja, Tommassen, Jan

CD4+ helper T cells recognize antigen in association with MHC class II molecules. To investigate the role of the context of a minimal T cell epitope on presentation and recognition in...

Novel Salmonella enterica Serovar Typhimurium Protein That Is Indispensable for Virulence and Intracellular Replication

Van Der Straaten, Tahar, Van Diepen, Angela, Kwappenberg, Kitty, Van Voorden, Sjaak, Franken, Kees, Janssen, Riny, ...

Upon contact with host cells, the intracellular pathogen Salmonella enterica serovar Typhimurium promotes its uptake, targeting, and survival in intracellular niches. In this process, the bacterium...

An Epitope Delivery System for Use with Recombinant Mycobacteria

Hetzel, Charlotte, Janssen, Riny, Ely, Sarah J., Kristensen, Nanna M., Bunting, Karen, Cooper, Jonathan B., ...

We have developed a novel epitope delivery system based on the insertion of peptides within a permissive loop of a bacterial superoxide dismutase molecule. This system allowed high-level expression...

A Superoxide-Hypersusceptible Salmonella enterica Serovar Typhimurium Mutant Is Attenuated but Regains Virulence in p47phox−/− Mice

Van Diepen, Angela, Van Der Straaten, Tahar, Holland, Steven M., Janssen, Riny, Van Dissel, Jaap T.

Salmonella enterica serovar Typhimurium is a gram-negative, facultative intracellular pathogen that predominantly invades mononuclear phagocytes and is able to establish persistent infections. One of...

Salmonella enterica Serovar Typhimurium RamA, Intracellular Oxidative Stress Response, and Bacterial Virulence

Van Der Straaten, Tahar, Zulianello, Laurence, Van Diepen, Angela, Granger, Donald L., Janssen, Riny, Van Dissel, Jaap T.

Escherichia coli and Salmonella enterica serovar Typhimurium have evolved genetic systems, such as the soxR/S and marA regulons, to detoxify reactive oxygen species, like superoxide, which are formed...

Salmonella Gene rma (ramA) and Multiple-Drug-Resistant Salmonella enterica Serovar Typhimurium

Van Der Straaten, Tahar, Janssen, Riny, Mevius, Dik J., Van Dissel, Jaap T.

MarA and its homologue, RamA, have been implicated in multidrug resistance (MDR). RamA overexpression in Salmonella enterica serovar Typhimurium and Escherichia coli conferred MDR independently of...

Gamma Irradiation or CD4+-T-Cell Depletion Causes Reactivation of Latent Salmonella enterica Serovar Typhimurium Infection in C3H/HeN Mice

Van Diepen, Angela, Van De Gevel, Joke S., Koudijs, Margaretha M., Ossendorp, Ferry, Beekhuizen, Henry, Janssen, Riny, ...

Upon infection with Salmonella, a host develops an immune response to limit bacterial growth and kill and eliminate the pathogen. Salmonella has evolved mechanisms to remain dormant within the body,...

Host Transcription Profiles upon Primary Respiratory Syncytial Virus Infection▿ †

Janssen, Riny, Pennings, Jeroen, Hodemaekers, Hennie, Buisman, Annemarie, Van Oosten, Marijke, De Rond, Lia, ...

Respiratory syncytial virus (RSV) is a common cause of severe lower respiratory tract infection in children. Severe RSV disease is related to an inappropriate immune response to RSV resulting in...

The Same IκBα Mutation in Two Related Individuals Leads to Completely Different Clinical Syndromes
