Brucella abortus is a facultative intracellular bacterium capable of surviving inside macrophages. The VirB complex, which is highly similar to conjugative DNA transfer apparatuses, is required for intracellular replication. A conserved NTP-binding domain in VirB4 suggests that one or both proteins couple energy by NTP hydrolysis to transport of putative effector molecule(s). Here it is shown t...
Synthetic lethal genetic interaction networks define genes that work together to control essential functions and have been studied extensively in Saccharomyces cerevisiae using the synthetic genetic array (SGA) analysis technique (ScSGA). The extent to which synthetic lethal or other genetic interaction networks are conserved between species remains uncertain. To address this question, we compa...
Hepatitis C virus (HCV) infection develops into chronicity in 80% of all patients, characterized by persistent low-level replication. To understand how the virus establishes its tightly controlled intracellular RNA replication cycle, we developed the first detailed mathematical model of the initial dynamic phase of the intracellular HCV RNA replication. We therefore quantitatively measured vira...
Positive-sense RNA viruses are responsible for frequent and often devastating diseases in humans, animals, and plants. However, the development of effective vaccines and anti-viral therapies targeted towards these pathogens has been hindered by an incomplete understanding of the molecular mechanisms involved in viral replication. One common feature of all positive-sense RNA viruses is the manip...
The facultative intracellular pathogen Salmonella enterica resides in a specific membrane-bound compartment termed the Salmonella-containing vacuole (SCV). Despite being segregated from access to metabolites in the host cell cytosol, Salmonella is able to efficiently proliferate within the SCV. We set out to unravel the nutritional supply of Salmonella in the SCV with focus on amino acids. We s...
conclusions core-lds interaction may be an underlying molecular mechanism to induce liver steatosis in patients with hcv infection. this interaction is also crucial for efficient viral replication and persistence in infected cells. steatosis can also interfere with efficient standard interferon therapy treatment. management of steatosis should be considered along with standard care for achievin...
