Abstract
Cancers associated with the oncogenic gammaherpesviruses, Epstein-Barr virus and Kaposi sarcoma herpesvirus, are notable for their constitutive activation of the transcription factor signal transducer and activator of transcription 3 (STAT3). To better understand the role of STAT3 during gammaherpesvirus latency and the B cell response to infection, we used the model pathogen murine gammaherpesvirus 68 (MHV68). Genetic deletion of STAT3 in B cells of CD19cre/+Stat3f/f mice reduced peak MHV68 latency approximately sevenfold. However, infected CD19cre/+Stat3f/f mice exhibited disordered germinal centers and heightened virus-specific CD8 T cell responses compared to wild-type (WT) littermates. To circumvent the systemic immune alterations observed in the B cell-STAT3 knockout mice and more directly evaluate intrinsic roles for STAT3, we generated mixed bone marrow chimeric mice consisting of WT and STAT3 knockout B cells. We discovered a dramatic reduction in latency in STAT3 knockout B cells compared to their WT B cell counterparts in the same lymphoid organ. RNA sequencing of sorted germinal center B cells revealed that MHV68 infection shifts the gene signature toward proliferation and away from type I and type II IFN responses. Loss of STAT3 largely reversed the virus-driven transcriptional shift without impacting the viral gene expression program. STAT3 promoted B cell processes of the germinal center, including IL-21-stimulated downregulation of surface CD23 on B cells infected with MHV68 or EBV. Together, our data provide mechanistic insights into the role of STAT3 as a latency determinant in B cells for oncogenic gammaherpesviruses.IMPORTANCEThere are no directed therapies to the latency program of the human gammaherpesviruses, Epstein-Barr virus and Kaposi sarcoma herpesvirus. Activated host factor signal transducer and activator of transcription 3 (STAT3) is a hallmark of cancers caused by these viruses. We applied the murine gammaherpesvirus pathogen system to explore STAT3 function upon primary B cell infection in the host. Since STAT3 deletion in all CD19+ B cells of infected mice led to altered B and T cell responses, we generated chimeric mice with both normal and STAT3-deleted B cells. B cells lacking STAT3 failed to support virus latency compared to normal B cells from the same infected animal. Loss of STAT3 impaired B cell proliferation and differentiation and led to a striking upregulation of interferon-stimulated genes. These findings expand our understanding of STAT3-dependent processes that are key to its function as a pro-viral latency determinant for oncogenic gammaherpesviruses in B cells and may provide novel therapeutic targets.

Abstract
Infection with chikungunya virus (CHIKV) causes disruption of draining lymph node (dLN) organization, including paracortical relocalization of B cells, loss of the B cell-T cell border, and lymphocyte depletion that is associated with infiltration of the LN with inflammatory myeloid cells. Here, we found that, during the first 24 hours of infection, CHIKV RNA accumulated in MARCO-expressing lymphatic endothelial cells (LECs) in both the floor and medullary LN sinuses. The accumulation of viral RNA in the LN was associated with a switch to an antiviral and inflammatory gene expression program across LN stromal cells, and this inflammatory response - including recruitment of myeloid cells to the LN - was accelerated by CHIKV-MARCO interactions. As CHIKV infection progressed, both floor and medullary LECs diminished in number, suggesting further functional impairment of the LN by infection. Consistent with this idea, antigen acquisition by LECs, a key function of LN LECs during infection and immunization, was reduced during pathogenic CHIKV infection.

Abstract
To disseminate through the body, Zika virus (ZIKV) is thought to exploit the mobility of myeloid cells, in particular monocytes and dendritic cells. However, the timing and mechanisms underlying shuttling of the virus by immune cells remains unclear. To understand the early steps in ZIKV transit from the skin, at different time points, we spatially mapped ZIKV infection in lymph nodes (LNs), an intermediary site en route to the blood. Contrary to prevailing hypotheses, migratory immune cells are not required for the virus to reach the LNs or blood. Instead, ZIKV rapidly infects a subset of sessile CD169+ macrophages in the LNs, which release the virus to infect downstream LNs. Infection of CD169+ macrophages alone is sufficient to initiate viremia. Overall, our experiments indicate that macrophages that reside in the LNs contribute to initial ZIKV spread. These studies enhance our understanding of ZIKV dissemination and identify another anatomical site for potential antiviral intervention.

Abstract
Disseminated coccidioidomycosis (DCM) is caused by Coccidioides, pathogenic fungi endemic to the southwestern United States and Mexico. Illness occurs in approximately 30% of those infected, less than 1% of whom develop disseminated disease. To address why some individuals allow dissemination, we enrolled patients with DCM and performed whole-exome sequencing. In an exploratory set of 67 patients with DCM, 2 had haploinsufficient STAT3 mutations, and defects in β-glucan sensing and response were seen in 34 of 67 cases. Damaging CLEC7A and PLCG2 variants were associated with impaired production of β-glucan-stimulated TNF-α from PBMCs compared with healthy controls. Using ancestry-matched controls, damaging CLEC7A and PLCG2 variants were overrepresented in DCM, including CLEC7A Y238* and PLCG2 R268W. A validation cohort of 111 patients with DCM confirmed the PLCG2 R268W, CLEC7A I223S, and CLEC7A Y238* variants. Stimulation with a DECTIN-1 agonist induced DUOX1/DUOXA1-derived hydrogen peroxide [H2O2] in transfected cells. Heterozygous DUOX1 or DUOXA1 variants that impaired H2O2 production were overrepresented in discovery and validation cohorts. Patients with DCM have impaired β-glucan sensing or response affecting TNF-α and H2O2 production. Impaired Coccidioides recognition and decreased cellular response are associated with disseminated coccidioidomycosis.

Abstract
Viremia in the vertebrate host is a major determinant of arboviral reservoir competency, transmission efficiency, and disease severity. However, immune mechanisms that control arboviral viremia are poorly defined. Here, we identify critical roles for the scavenger receptor MARCO in controlling viremia during arthritogenic alphavirus infections in mice. Following subcutaneous inoculation, arthritogenic alphavirus particles drain via the lymph and are rapidly captured by MARCO+ lymphatic endothelial cells (LECs) in the draining lymph node (dLN), limiting viral spread to the bloodstream. Upon reaching the bloodstream, alphavirus particles are cleared from the circulation by MARCO-expressing Kupffer cells in the liver, limiting viremia and further viral dissemination. MARCO-mediated accumulation of alphavirus particles in the draining lymph node and liver is an important host defense mechanism as viremia and viral tissue burdens are elevated in MARCO-/- mice and disease is more severe. In contrast to prior studies implicating a key role for lymph node macrophages in limiting viral dissemination, these findings exemplify a previously unrecognized arbovirus-scavenging role for lymphatic endothelial cells and improve our mechanistic understanding of viremia control during arthritogenic alphavirus infection.

Abstract
Although enteric helminth infections modulate immunity to mucosal pathogens, their effects on systemic microbes remain less established. Here, we observe increased mortality in mice coinfected with the enteric helminth Heligmosomoides polygyrus bakeri (Hpb) and West Nile virus (WNV). This enhanced susceptibility is associated with altered gut morphology and transit, translocation of commensal bacteria, impaired WNV-specific T cell responses, and increased virus infection in the gastrointestinal tract and central nervous system. These outcomes were due to type 2 immune skewing, because coinfection in Stat6-/- mice rescues mortality, treatment of helminth-free WNV-infected mice with interleukin (IL)-4 mirrors coinfection, and IL-4 receptor signaling in intestinal epithelial cells mediates the susceptibility phenotypes. Moreover, tuft cell-deficient mice show improved outcomes with coinfection, whereas treatment of helminth-free mice with tuft cell-derived cytokine IL-25 or ligand succinate worsens WNV disease. Thus, helminth activation of tuft cell-IL-4-receptor circuits in the gut exacerbates infection and disease of a neurotropic flavivirus.

Abstract
The oropharyngeal mucosa serves as a perpetual pathogen entry point and a critical site for viral replication and spread. Here, we demonstrate that type 1 innate lymphoid cells (ILC1s) were the major immune force providing early protection during acute oral mucosal viral infection. Using intravital microscopy, we show that ILC1s populated and patrolled the uninfected labial mucosa. ILC1s produced interferon-γ (IFN-γ) in the absence of infection, leading to the upregulation of key antiviral genes, which were downregulated in uninfected animals upon genetic ablation of ILC1s or antibody-based neutralization of IFN-γ. Thus, tonic IFN-γ production generates increased oral mucosal viral resistance even before infection. Our results demonstrate barrier-tissue protection through tissue surveillance in the absence of rearranged-antigen receptors and the induction of an antiviral state during homeostasis. This aspect of ILC1 biology raises the possibility that these cells do not share true functional redundancy with other tissue-resident lymphocytes.

Abstract
Humoral immune responses initiate in the lymph node draining the site of viral infection (dLN). Some viruses subvert LN B cell activation; however, our knowledge of viral hindrance of B cell responses of important human pathogens is lacking. Here, we define mechanisms whereby chikungunya virus (CHIKV), a mosquito-transmitted RNA virus that causes outbreaks of acute and chronic arthritis in humans, hinders dLN antiviral B cell responses. Infection of WT mice with pathogenic, but not acutely cleared CHIKV, induced MyD88-dependent recruitment of monocytes and neutrophils to the dLN. Blocking this influx improved lymphocyte accumulation, dLN organization, and CHIKV-specific B cell responses. Both inducible nitric oxide synthase (iNOS) and the phagocyte NADPH oxidase (Nox2) contributed to impaired dLN organization and function. Infiltrating monocytes expressed iNOS through a local IRF5- and IFNAR1-dependent pathway that was partially TLR7-dependent. Together, our data suggest that pathogenic CHIKV triggers the influx and activation of monocytes and neutrophils in the dLN that impairs virus-specific B cell responses. Elucidating mechanisms by which viruses subvert B cell immunity and establish persistent infection is essential for the development of new therapeutic strategies against chronic viral infections. The humoral immune response initiates in the lymph node draining the site of viral infection. However, how persistent viruses evade B cell responses is poorly understood. In this study, we find that infection with pathogenic, persistent chikungunya virus triggers rapid recruitment of neutrophils and monocytes to the draining lymph node, which impair structural organization, lymphocyte accumulation, and downstream virus-specific B cell responses that are important for control of infection. This work enhances our understanding of the pathogenesis of acute and chronic CHIKV disease and highlights how local innate immune responses in draining lymphoid tissue dictate the effectiveness of downstream adaptive immunity.

Abstract
Abstract
The generation of a robust CD8+ T cell response is critical for the elimination of virally infected cells and is dependent on presentation of viral antigen in the draining lymph node. Although we know much about antigen presentation in general, how antiviral T cell activation is precisely accomplished at the spatial level remains incompletely understood. Much of our knowledge of spatial details of viral antigen presentation derives from studies in which virus is subcutaneously injected, which likely differs greatly from presentation after virus replicates in the tissue and naturally drains to the regional lymph node. In order to better understand viral antigen presentation in the lymph node after viral replication in the skin and the impact on the initiation of CD8+ T cell responses, we infected mice in the ear pinna with vaccinia virus (VACV) epicutaneously using a bifurcated needle. VACV replicates to high titers in the skin, and viral antigen and genomes are detectable in the draining cervical lymph node by day 5 post infection, far beyond that after subcutaneous VACV injection. We are currently exploring the spatiotemporal dynamics of T cell activation as well as the antigen presenting cell subsets important for priming after epicutanous VACV infection. These findings are of significance for both our basic understanding of antiviral immunity and for the development of new T cell-based vaccination strategies, where optimization of CD8+ T cell responses is essential.

Abstract
Abstract
Smallpox, caused by infection with variola virus, led to devastating human pandemics with high mortality until eradication through a global vaccination campaign. Despite eradication, the precise immune mechanisms underlying recovery from infection are incompletely understood. The most common model employed to study smallpox is murine infection with vaccinia virus (VACV), the virus used for human smallpox vaccination. VACV models of smallpox infection commonly employ intranasal or even intravenous routes of infection, with both resulting in widespread viral dissemination. However, variola virus infected humans through the oropharyngeal mucosa, after which oral lesions developed and ruptured, spilling copious infectious virus into the saliva (the route of human-to-human spread). To understand protection in this critical barrier site, we developed a mouse model of lip (labial mucosal) infection. After labial administration, VACV replicates to high titers and two waves of group I innate lymphoid cells (ILCs) are recruited in response to infection. Intravital imaging revealed highly mobile ILCs in the oral mucosa, most of which failed to contact virus-infected cells. Despite the lack of stable contacts, depletion of NK1.1+ cells enhanced viral replication and spread. Instead, ILCs delivered IFN-γ to the mucosal tissue, inducing an antiviral signature in the epithelium. Together, these data illustrate the complex nature of immune protection in a critical yet overlooked tissue during viral pathogenesis.

Abstract
Abstract
Despite intense interest in antiviral T cell priming, the routes of virion movement in lymph nodes (LNs) are imperfectly understood. Current models fail to explain how virus-infected cells rapidly appear within the LN interior after viral infection. To better understand virion trafficking in the LN, we determined virion and infected-cell locations after pox- and zika-virus administration. Surprisingly, many rapidly infected cells in the LN interior were adjacent to LN conduits. Using confocal and electron microscopy, we clearly visualized virions within conduits. Functionally, CD8+ T cells rapidly and preferentially associated with vaccinia-infected cells deeper in the LN, leading to T cell activation in the LN interior. These results reveal that, contrary to dogma, even large virions can flow through lymph node conduits to infect T cell zone DCs that prime CD8 + T cells.

Abstract
Abstract
CD8+ T cells play a critical role in the elimination of viral infections. After epicutaneous infection with vaccinia virus (VACV), virus replicates in skin keratinocytes and antigen drains to the lymph node, priming antigen-specific CD8+ T cells. Once activated, CD8+ T cell migration into the skin occurs independent of cognate antigen recognition. In laboratory mice, which are immunologically naive prior to viral infection, only antigen-specific CD8+ T cells are activated and can migrate into the skin. However, as humans are exposed to many more pathogens than laboratory mice, activated CD8+ cells present in the circulation can be recruited to the site of infection, regardless of their antigen specificity. To model this phenomenon in mice, we adoptively transferred OT-I CD8+ T cells, infected in the footpad with non-replicating virus to activate these T cells, and then infected epicutaneously with recombinant VACV expressing or lacking SIINFEKL (the cognate antigen for OT-I cells). This system allows the robust recruitment of both antigen-specific and non-specific antiviral CD8+ T cells into the skin. Using a combination of flow cytometry and confocal and intravital microscopy, we are currently investigating the spatial distribution of antigen-specific and non-specific CD8+ T cells in the skin. Additionally, we are quantifying cytokine production by these CD8+ T cells under various conditions, including after infection with viruses expressing distinct antigens, in close proximity. These studies should provide additional clarity on the role of antigen in CD8+ T cell spatial distribution in infected peripheral tissues.

Abstract
Cell motility is essential for viral dissemination1. Vaccinia virus (VACV), a close relative of smallpox virus, is thought to exploit cell motility as a means to enhance the spread of infection1. A single viral protein, F11L, contributes to this by blocking RhoA signalling to facilitate cell retraction2. However, F11L alone is not sufficient for VACV-induced cell motility, indicating that additional viral factors must be involved. Here, we show that the VACV epidermal growth factor homologue, VGF, promotes infected cell motility and the spread of viral infection. We found that VGF secreted from early infected cells is cleaved by ADAM10, after which it acts largely in a paracrine manner to direct cell motility at the leading edge of infection. Real-time tracking of cells infected in the presence of EGFR, MAPK, FAK and ADAM10 inhibitors or with VGF-deleted and F11-deleted viruses revealed defects in radial velocity and directional migration efficiency, leading to impaired cell-to-cell spread of infection. Furthermore, intravital imaging showed that virus spread and lesion formation are attenuated in the absence of VGF. Our results demonstrate how poxviruses hijack epidermal growth factor receptor-induced cell motility to promote rapid and efficient spread of infection in vitro and in vivo.

Abstract
Intravital multiphoton microscopy (MPM) allows the direct visualization of viral infections in real time as they occur in living animals. Here we describe the routes and considerations for murine infection with vaccinia virus (VACV) for imaging, and the preparation of the skin and inner lip (labial mucosa) of infected animals for MPM. Using different recombinant VACVs expressing fluorescent proteins in combination with transgenic fluorescent reporter mice, MPM imaging can be used to examine the movements, interactions, and functions of virus-infected cells or selected immune cell populations after infection.

Abstract
Probing the limits of CD8+ T cell immunosurveillance, we inserted the SIINFEKL peptide into influenza A virus (IAV)-negative strand gene segments. Although IAV genomic RNA is considered noncoding, there is a conserved, relatively long open reading frame present in segment 8, encoding a potential protein termed NEG8. The biosynthesis of NEG8 from IAV has yet to be demonstrated. Although we failed to detect NEG8 protein expression in IAV-infected mouse cells, cell surface Kb-SIINFEKL complexes are generated when SIINFEKL is genetically appended to the predicted C terminus of NEG8, as shown by activation of OT-I T cells in vitro and in vivo. Moreover, recombinant IAV encoding of SIINFEKL embedded in the negative strand of the neuraminidase-stalk coding sequence also activates OT-I T cells in mice. Together, our findings demonstrate both the translation of sequences on the negative strand of a single-stranded RNA virus and its relevance in antiviral immunosurveillance.

Abstract
Chikungunya virus (CHIKV) causes acute and chronic rheumatologic disease. Pathogenic CHIKV strains persist in joints of immunocompetent mice, while the attenuated CHIKV strain 181/25 is cleared by adaptive immunity. We analyzed the draining lymph node (dLN) to define events in lymphoid tissue that may contribute to CHIKV persistence or clearance. Acute 181/25 infection resulted in dLN enlargement and germinal center (GC) formation, while the dLN of mice infected with pathogenic CHIKV became highly disorganized and depleted of lymphocytes. Using CHIKV strains encoding ovalbumin-specific TCR epitopes, we found that lymphocyte depletion was not due to impaired lymphocyte proliferation. Instead, the accumulation of naive lymphocytes transferred from the vasculature to the dLN was reduced, which was associated with fewer high endothelial venule cells and decreased CCL21 production. Following NP-OVA immunization, NP-specific GC B cells in the dLN were decreased during pathogenic, but not attenuated, CHIKV infection. Our data suggest that pathogenic, persistent strains of CHIKV disable the development of adaptive immune responses within the dLN.

Abstract
Influenza A virus gene segment 7 encodes two proteins: the M1 protein translated from unspliced mRNA and the M2 protein produced by mRNA splicing and largely encoded by the M1 +1 reading frame. To better understand the generation of defective ribosomal products relevant to MHC class I Ag presentation, we engineered influenza A virus gene segment 7 to encode the model H-2 K(b) class I peptide ligand SIINFEKL at the M2 protein C terminus. Remarkably, after treating virus-infected cells with the RNA splicing inhibitor spliceostatin A to prevent M2 mRNA generation, K(b)-SIINFEKL complexes were still presented on the cell surface at levels ≤60% of untreated cells. Three key findings indicate that SIINFEKL is produced by cytoplasmic translation of unspliced M1 mRNA initiating at CUG codons within the +1 reading frame: 1) synonymous mutation of CUG codons in the M2-reading frame reduced K(b)-SIINFEKL generation; 2) K(b)-SIINFEKL generation was not affected by drug-mediated inhibition of AUG-initiated M1 synthesis; and 3) K(b)-SIINFEKL was generated in vitro and in vivo from mRNA synthesized in the cytoplasm by vaccinia virus, and hence cannot be spliced. These findings define a viral defective ribosomal product generated by cytoplasmic noncanonical translation and demonstrate the participation of CUG-codon-based translation initiation in pathogen immunosurveillance.

Abstract
Skin infection with the poxvirus vaccinia (VV) elicits a powerful, inflammatory cellular response that clears virus infection in a coordinated, spatially organized manner. Given the high concentration of pro-inflammatory effectors at areas of viral infection, it is unclear how tissue pathology is limited while virus-infected cells are being eliminated. To better understand the spatial dynamics of the anti-inflammatory response to a cutaneous viral infection, we first screened cytokine mRNA expression levels after epicutaneous (ec.) VV infection and found a large increase the anti-inflammatory cytokine IL-10. Ex vivo analyses revealed that T cells in the skin were the primary IL-10-producing cells. To understand the distribution of IL-10-producing T cells in vivo, we performed multiphoton intravital microscopy (MPM) of VV-infected mice, assessing the location and dynamic behavior of IL-10 producing cells. Although virus-specific T cells were distributed throughout areas of the inflamed skin lacking overt virus-infection, IL-10+ cells closely associated with large keratinocytic foci of virus replication where they exhibited similar motility patterns to bulk antigen-specific CD8+ T cells. Paradoxically, neutralizing secreted IL-10 in vivo with an anti-IL-10 antibody increased viral lesion size and viral replication. Additional analyses demonstrated that IL-10 antibody administration decreased recruitment of CCR2+ inflammatory monocytes, which were important for reducing viral burden in the infected skin. Based upon these findings, we conclude that spatially concentrated IL-10 production limits cutaneous viral replication and dissemination, likely through modulation of the innate immune repertoire at the site of viral growth.

Abstract
CD8(+) T cells play a critical role in limiting peripheral virus replication, yet how they locate virus-infected cells within tissues is unknown. Here, we have examined the environmental signals that CD8(+) T cells use to localize and eliminate virus-infected skin cells. Epicutaneous vaccinia virus (VV) infection, mimicking human smallpox vaccination, greatly increased expression of the CXCR3 chemokine receptor ligands CXCL9 and CXCL10 in VV-infected skin. Despite normal T cell numbers in the skin, Cxcr3(-/-) mice exhibited dramatically impaired CD8(+)-T-cell-dependent virus clearance. Intravital microscopy revealed that Cxcr3(-/-) T cells were markedly deficient in locating, engaging, and killing virus-infected cells. Further, transfer of wild-type CD8(+) T cells restored viral clearance in Cxcr3(-/-) animals. These findings demonstrate a function for CXCR3 in enhancing the ability of tissue-localized CD8(+) T cells to locate virus-infected cells and thereby exert anti-viral effector functions.

Abstract
Despite extensive ex vivo investigation, the spatiotemporal organization of immune cells interacting with virus-infected cells in tissues remains uncertain. To address this, we used intravital multiphoton microscopy to visualize immune cell interactions with virus-infected cells following epicutaneous vaccinia virus (VV) infection of mice. VV infects keratinocytes in epidermal foci and numerous migratory dermal inflammatory monocytes that outlie the foci. We observed Ly6G(+) innate immune cells infiltrating and controlling foci, while CD8(+) T cells remained on the periphery killing infected monocytes. Most antigen-specific CD8(+) T cells in the skin did not interact with virus-infected cells. Blocking the generation of reactive nitrogen species relocated CD8(+) T cells into foci, modestly reducing viral titers. Depletion of Ly6G(+) and CD8(+) cells dramatically increased viral titers, consistent with their synergistic but spatially segregated viral clearance activities. These findings highlight previously unappreciated differences in the anatomic specialization of antiviral immune cell subsets.

Abstract
CCR5-binding chemokines produced in the draining lymph node after vaccinia virus infection guide naive CD8+ T cells toward DCs and away from the macrophage-rich zone, thereby facilitating optimal CD8+ T cell activation and cytokine production. Naive antiviral CD8+ T cells are activated in the draining LN (DLN) by dendritic cells (DCs) presenting viral antigens. However, many viruses infect LN macrophages, which participate in initiation of innate immunity and B cell activation. To better understand how and why T cells select infected DCs rather than macrophages, we performed intravital microscopy and ex vivo analyses after infecting mice with vaccinia virus (VV), a large DNA virus that infects both LN macrophages and DCs. Although CD8+ T cells interact with both infected macrophages and DCs in the LN peripheral interfollicular region (PIR), DCs generate more frequent and stable interactions with T cells. VV infection induces rapid release of CCR5-binding chemokines in the LN, and administration of chemokine-neutralizing antibodies diminishes T cell activation by increasing T cell localization to macrophages in the macrophage-rich region (MRR) at the expense of PIR DCs. Similarly, DC ablation increases both T cell localization to the MRR and the duration of T cell–macrophage contacts, resulting in suboptimal T cell activation. Thus, virus-induced chemokines in DLNs enable antiviral CD8+ T cells to distinguish DCs from macrophages to optimize T cell priming.
