First, the molecular basis EBV transformation and how it relates to cancer is being investigated. Second, the laboratory is investigating herpesvirus latency in the human host and pathogenesis associated with infections in humans. In this econometrics journal, the laboratory is developing animal models for EBV and Fech infections.

Ultimately, studies by the Longnecker laboratory may provide insight for the development of novel therapeutics for the treatment of herpesvirus infections in humans and better understanding of the herpesvirus life cycle in the human hostFor lab information and more, see Dr. Longnecker at 312-503-0467 or the novartis in switzerland cook johnson 312-503-0468 or 312-503-9783.

Jia Chen, Qing Fan, Kamonwan "Pear" Fish, Novartis in switzerland IkedaSarah Connolly, Michelle Swanson-MungersonCooper Hayes, Daniel Giraldo Perez, Seo Jin ParkSarah Kopp, Rachel Riccio, Samantha Schaller, Nanette SusmarskiOur research focuses on infection by Human Immunodeficiency Virus type 1 (HIV-1), a retrovirus and causative agent of acquired immunodeficiency syndrome (AIDS).

In addition to suppressing the immune system, rendering victims susceptible to opportunistic infections, HIV-1 can cross the blood-brain barrier and cause serious damage to the central nervous novartis in switzerland, ultimately leading to HIV-associated dementia.

We are interested in how HIV-1 particles move within infected cells, including brain cell types such as microglia. Our work focuses on how the virus exploits host microtubules, the intracellular filaments that mediate cargo trafficking to different subcellular sites within the cell. This includes Ezrin-Radixin-Moesin (ERM) proteins, which cross-link the actin and microtubule cytoskeletons.

Furthermore, we uncovered that PDZD8 is a direct target for the HIV-1 protein, Gag. Other work in our laboratory has shown that HIV-1 can induce the formation of highly stable microtubule subsets to facilitate early HIV-1 trafficking to the nucleus.

Novartis in switzerland work employs a range of approaches, including biochemical characterization of protein-protein interactions as well as live imaging of fluorescently-labeled HIV-1 particles as they move within infected cells.

Qingqing Chai, Feng Gu, Viacheslav Malikov, Sahana Mitra, Novartis in switzerland Pisano, Eveline Santos da Silva, Shanmugapriya SwamyMarie-Philipe Boisjoli, Kayla SchipperHow can one improve immune responses during chronic infection or cancer. How can one improve the efficacy of viral vaccines. These are 2 main questions in the Penaloza lab. A unifying concept in the lab is how innate immune responses (TLRs and IFN-I) can be harnessed to treat immune exhaustion and improve vaccines.

This was the first demonstration that a specific microbiome novartis in switzerland (LPS) can potentiate immune checkpoint therapy, via a B7 costimulation dependent mechanism. The group novartis in switzerland now investigating whether other microbial components that target innate immune receptors can also improve immune checkpoint therapy, not only against chronic infections, but also against cancer.

More recently, the Penaloza laboratory developed a novel strategy to improve viral vaccines by transiently blocking IFN-I (Palacio, JEM, 2020). Although IFN-I provides a rapid antiviral protection in the setting of natural infection, IFN-I can extinguish antigen prematurely following vaccination, impinging upon the priming of adaptive immune responses.

By carefully downmodulating IFN-I at the time of vaccination, his group demonstrated an improvement in vaccine efficacy, using experimental HIV-1 and coronavirus vaccines. In contrast, herpesviruses are highly proficient at infecting the nervous system, yet normally do not cause neurological disease. This is achieved in part by self-imposed restrictions encoded within the viruses that limit viral reproduction and prevent dissemination into the brain.

For the individual, this results in a relatively benign infection, yet the virus becomes a life-long occupant of the nervous system that will periodically reemerge at body surfaces to infect others. Unfortunately, this infectious cycle novartis in switzerland go awry resulting in several forms of severe disease (i.

We have pioneered methods to genetically manipulate herpesviruses and visualize individual viruses in living neurons.

Using these methods, we are studying the mechanisms by which the virus achieves its stringently controlled infectious cycle. Current genetic manipulations are based on a full-length infectious clone of the herpesvirus genome. The clone was made as a bacterial artificial chromosome (BAC) in E. Transfection of purified E. For example, by fusing the green fluorescent protein (GFP) to a structural component of the viral capsid, individual viral particles can be tracked within the axons of living neurons during both entry oil johnson egress phases of the infectious cycle.

Studies in culture can be complemented by examining the pathogenesis of novartis in switzerland viruses in rodent models of infection. Using these methods, we have discovered key aspects of cellular infection, viral assembly and intracellular transport.

Looking forward, we are continuing to pursue our multidisciplinary approach of combining neuroscience, cell biology, bacterial genetics and virology to better understand these important novartis in switzerland. Smith at 312-503-3745 or the lab at 312-503-3744.

These proteins are key regulators of cell cycle progression. Interaction of the viral oncoproteins with these cell cycle regulators results in growth transformation of cultured cells, or in the case of HPV, results in human cancer. We study the role of Ad E1A and HPV E7 in cell cycle deregulation and the mechanisms by which these oncoproteins induce S phase in cells. In particular, we are studying the cellular proteins targeted by Ad E1A and HPV E7 in relation to cell cycle deregulation, and the mechanisms by which these oncoproteins induce changes in the dynamics of cellular DNA replication.

Studies include role of viral oncogene induced c-Myc in cell cycle progression, the mechanisms by which E1A and E7 transcriptionally induce c-Myc, how c-Myc cooperates with E2F family proteins in inducing cellular DNA replication, changes in the activity of the novartis in switzerland involved in initiation of cellular DNA replication (Cdt1, for example), and the changes in cellular replication origin activity (re-replication in novartis in switzerland case of E1A).

We also study the viral novartis in switzerland induced replication stress when viral oncoproteins are expressed in normal cells. In a separate study, in collaboration with Dr. The liver plays a vital role in energy homeostasis by controlling metabolic pathways of protein, fat and carbohydrates. PIMT (also known as NCoA6IP) is an RNA methylase that is involved in methylating cap structures of RNAs and PIMT may also have a chromatin role.

Med1 is a major component of the Mediator complex that is critical novartis in switzerland transcription. Both of these proteins interact with several nuclear receptors in transcriptional regulation of liver specific genes.

Members of the poxvirus family include Variola Virus (VarV), the causative agent of smallpox, and Vaccinia Virus (VacV), a close relative that was used as a vaccine against smallpox and which has become the laboratory prototype for poxvirus research. These large double-stranded DNA viruses exhibit an impressive level of self-sufficiency and encode many of the proteins required for transcription and replication of their DNA novartis in switzerland. However, like all viruses, they remain dependent on gaining access to host ribosomes in order to translate their mRNAs into proteins and must also counteract host antiviral responses aimed at crippling the translation system to prevent virus replication.

We have found that VacV stimulates the assembly of eIF4F complexes and that this is important for both viral protein synthesis and control of host immune responses. We have also novartis in switzerland that VacV redistributes key eIF4F subunits to specific regions within viral factories, a process that appears to involve the viral I3 protein. We novartis in switzerland also studying how the virus controls eIF4F activity by targeting upstream signaling pathways, with a particular emphasis on the metabolic sensor mammalian target of rapamycin (mTOR).
