In the Ferris lab, we use genetically diverse mouse strains to better understand the role of genetic variation in immune responses to a variety of insults. We then study these variants mechanistically. We also develop genetic and genomic datasets and resources to better identify genetic features associated with these immunological differences.

My research aims to understand the pathogenesis and host immune response to emerging and re-emerging viral infections, including encephalitic alphaviruses such as chikungunya virus and respiratory coronaviruses such as SARS-CoV-2. Other areas of interest include examination of genetic and environmental factors that influence the response to infection and disease outcome, evaluation of vaccines and novel therapeutics against emerging viruses, and development and optimization of animal models of infectious disease.

We want to understand why common pediatric respiratory virus infections cause severe disease in some people. Currently we focus on enterovirus D68, which typically causes colds but rarely causes acute flaccid myelitis, a polio-like paralyzing illness in children. We study both the pathogen and the host immune response, as both can contribute to pathogenesis. Projects focus on use of reverse genetic systems to create reporter viruses to infect both human respiratory epithelial cultures and small animal models such as mice. Human monoclonal antibody effects on pathogenesis are also of interest.

We use studies of HIV/SIV evolution to reveal information about viral dynamics in vivo. This typically involves genetic and/or phenotypic analyses of viral populations in samples from HIV-infected humans or SIV-infected nonhuman primates (NHPs). We are currently exploring the mechanisms that contribute to neurocognitive impairment in HIV-infected people by sequencing viral populations in the CNS of humans and NHPs not on antiretroviral therapy. We are also using these approaches to examine viral populations that persist during long-term antiretroviral therapy in an effort to better understand the viral reservoirs that must be targeted in order to cure HIV-infected people.

My research interests are focused on mechanisms associated with altered innate immune functions, which lead to dysregulated adaptive immunity. Currently my research program has three major arms integrated through with a central philosophy. Specifically, our laboratory focuses on the contribution of epithelial cell biology and signaling to innate and adaptive immune homeostasis and dysfunction. We study the contribution of what I term ‘epithelial cell innate immune (dys)function’ to three major disease conditions: pancreatic cancer, type 1 diabetes (autoimmunity), and periodontal disease (autoinflammation). While appearing to be a diverse research program, we have found that many of the mechanisms and systems in play are surprisingly (or maybe not so surprisingly) similar allowing for rapid translation of our findings. Importantly, previous investigations into the role of epithelial cells in immunobiology have been hindered by a lack of robust primary cell culture techniques, which our laboratory has been able to overcome using both animal and human tissues. Thus, using our novel and unique tools we are able to evaluate our findings in the human conditions, again making translation of our findings that much more feasible. In addition to my primary research objectives, my collaborative research programs, have allowed me to be involved, at some level, in investigating the basic biology of health, multiple autoimmune conditions, autoinflammation, sepsis, and exercise induced inflammation I have been blessed with the opportunities to couple my passions and expertise with that of others to bring together multiple research communities with the goal of advancing human health and hope to be able to continue to do so for years to come.

We study the molecular mechanisms of HIV latency. Transcriptional silencing of HIV is a key mechanism of persistence in patients, and is a barrier to viral eradication, but little is known about the latent reservoir or the molecular mechanisms that regulate it. As such, our repertoire of drugs for targeting latently infected cells is limited. Some latency reversing agents (LRAs) have been developed, but these are typically reactivate only a minor subset of proviruses. This inefficiency is in part due to the reservoir not constituting a uniform target, but instead being a heterogeneous set of cells with diverse characteristics and restrictions to HIV expression. However, most analyses of latency use bulk cell cultures assays in which crucial information about the behavior of individual cells is lost. Also, latently infected cells in patient samples are exceedingly rare, making them very difficult to study directly. New technological breakthroughs in the field of single cell analysis as well as the development of primary cell models for HIV latency now open the possibility of observing how latently infected cells form and are maintained at single cell resolution. Our lab has developed tools to study the establishment, maintenance and reversal of HIV latency at single cell resolution using multi-omics methods. Furthermore, we combine these approaches with genetic perturbation, time-lapse microscopy and novel bioengineering tools to gain insight into how the host cell regulates HIV latency. We have recently discovered using single cell RNAseq (scRNAseq) that latency in primary CD4 T cells is associated with expression of a distinct transcriptional signature (Bradley et al 2018). Our hypothesis is that this signature represents part of a cellular program that regulates latency, and that this program is an exciting novel target for the development of LRAs. Ongoing projects in the lab involve the application of new technologies to our model systems, and testing/validation of the roles of host cell pathways we have identified in HIV latency. Our overall goal is to identify new targets for the development of drugs to clear the HIV reservoir.

Research in my lab focuses on investigating sex specific effects of air pollutants and new and emerging tobacco products on respiratory immune health. Specifically, the Rebuli lab is examining how the interaction of sex (genetic and hormonal) and toxicant exposure can alter respiratory health. As the majority of research has been historically conducted in men, male animals, or male-derived cell culture models, there is a paucity of information on female respiratory health and sex differences in the effects of toxicant exposure. We are working to fill this knowledge gap by better understanding the role of genetic and hormonal sex on respiratory health. This is particularly important in understanding the development of sex-biased diseases, where men or women are more susceptible to disease development after environmental exposures, such viral infection, asthma, and chronic obstructive pulmonary disease (COPD). We are interested in toxicants such as ozone, wood smoke, cigarette smoke, and e-cigarette aerosols. We investigate effects at both the individual and population level by using clinical (observational clinical studies and prospective exposure trials) and translational (in vitro and ex vivo cell culture) models of the respiratory immune system.

The overall focus of our lab is to develop new and exciting approaches for enhancing the efficacy of cancer immunotherapies. We utilize cutting-edge techniques to identify transcriptional and epigenetic regulators controlling T cell differentiation and function in the tumor microenvironment, and we seek to leverage this insight to reprogram or tailor the activity of T cells in cancer. Our group is also interested in understanding how to harness or manipulate T cell function to improve vaccines and immunotherapies for acute and chronic infections.

Antiretroviral therapy (ART) is effective in suppressing HIV-1 replication in the periphery, however, it fails to eradicate HIV-1 reservoirs in patients. The main barrier for HIV cure is the latent HIV-1, hiding inside the immune cells where no or very low level of viral particles are made. This prevents our immune system to recognize the latent reservoirs to clear the infection. The main goal of my laboratory is to discover the molecular mechanisms how HIV-1 achieves its latent state and to translate our understanding of HIV latency into therapeutic intervention.

Several research programs are undertaking in my lab with a focus of epigenetic regulation of HIV latency, including molecular mechanisms of HIV replication and latency establishment, host-virus interaction, innate immune response to viral infection, and the role of microbiome in the gut health. Extensive in vitro HIV latency models, ex vivo patient latency models, and in vivo patient and rhesus macaque models of AIDS are carried out in my lab. Multiple tools are applied in our studies, including RNA-seq, proteomics, metabolomics, highly sensitive digital droplet PCR and tissue RNA/DNAscope, digital ELISA, and modern and traditional molecular biological and biochemical techniques. We are also very interested in how non-CD4 expression cells in the Central Nervous System (CNS) get infected by HIV-1, how the unique interaction among HIV-1, immune cells, vascular cells, and neuron cells contributes to the initial seeding of latent reservoirs in the CNS, and whether we can target the unique viral infection and latency signaling pathways to attack HIV reservoirs in CNS for a cure/remission of HIV-1 and HIV-associated neurocognitive disorders (HAND). We have developed multiple tools to attack HIV latency, including latency reversal agents for “Shock and Kill” strategy, such as histone deacetylase inhibitors and ingenol family compounds of protein kinase C agonists, and latency enforcing agents for deep silencing of latent HIV-1. Several clinical and pre-clinical studies are being tested to evaluate their potential to eradicate latent HIV reservoirs in vivo. We are actively recruiting postdocs, visiting scholars, and technicians. Rotation graduate students and undergraduate students are welcome to join my lab, located in the UNC HIV Cure Center, for these exciting HIV cure research projects.
