Abstract
Metabolic programming and reprogramming have emerged as pivotal mechanisms for altering immune cell function. Thus, immunometabolism has become an attractive target area for treatment of immune-mediated disorders. Nonetheless, many hurdles to delivering metabolic cues persist. In this review, we consider how biomaterials are poised to transform manipulation of immune cell metabolism through integrated control of metabolic configurations to affect outcomes in autoimmunity, regeneration, transplant, and cancer. We emphasize the features of nanoparticles and other biomaterials that permit delivery of metabolic cues to the intracellular compartment of immune cells, or strategies for altering signals in the extracellular space. We then provide perspectives on the potential for reciprocal regulation of immunometabolism by the physical properties of materials themselves. Lastly, opportunities for clinical translation are highlighted. This discussion contributes to our understanding of immunometabolism, biomaterials-based strategies for altering metabolic configurations in immune cells, and emerging concepts in this evolving field.

Abstract
Recent clinical studies show activating multiple innate immune pathways drives robust responses in infection and cancer. Biomaterials offer useful features to deliver multiple cargos, but add translational complexity and intrinsic immune signatures that complicate rational design. Here a modular adjuvant platform is created using self-assembly to build nanostructured capsules comprised entirely of antigens and multiple classes of toll-like receptor agonists (TLRas). These assemblies sequester TLR to endolysosomes, allowing programmable control over the relative signaling levels transduced through these receptors. Strikingly, this combinatorial control of innate signaling can generate divergent antigen-specific responses against a particular antigen. These assemblies drive reorganization of lymph node stroma to a pro-immune microenvironment, expanding antigen-specific T cells. Excitingly, assemblies built from antigen and multiple TLRas enhance T cell function and antitumor efficacy compared to ad-mixed formulations or capsules with a single TLRa. Finally, capsules built from a clinically relevant human melanoma antigen and up to three TLRa classes enable simultaneous control of signal transduction across each pathway. This creates a facile adjuvant design platform to tailor signaling for vaccines and immunotherapies without using carrier components. The modular nature supports precision juxtaposition of antigen with agonists relevant for several innate receptor families, such as toll, STING, NOD, and RIG.

Abstract
Biomaterials hold great promise for vaccines and immunotherapy. One emerging biomaterials technology is microneedle (MNs) delivery. MNs are arrays of micrometer-sized needles that are painless and efficiently deliver cargo to the specialized immunological niche of the skin. MNs typically do not require cold storage and eliminate medical sharps. Nearly all materials exhibit intrinsic properties that can bias immune responses toward either pro-immune or inhibitory effects. Thus, because MNs are fabricated from degradable polymers to enable cargo loading and release, understanding the immunological profiles of these matrices is essential to enable new MN vaccines and immunotherapies. Additionally, understanding the mechanical properties is important because MNs must penetrate the skin and conform to a variety of skin or tissue geometries. Here we fabricated MNs from important polymer classes – including extracellular matrix biopolymers, naturally-derived polymers, and synthetic polymers – with both high- and low-molecular-weights (MW). We then characterized the mechanical properties and intrinsic immunological properties of these designs. The library of polymer MNs exhibited diverse mechanical properties, while causing only modest changes in innate signaling and antigen-specific T cell proliferation. These data help inform the selection of MN substrates based on the mechanical and immunological requirements needed for a specific vaccine or immunotherapy application.

Abstract
The coronavirus disease 2019 (COVID-19) public health crisis has reached critical mass, but interdisciplinary research efforts have provided the global community with the first effective medical intervention to fight the pandemic—COVID-19 vaccines. Two of the vaccines approved for use in the United States and Europe deliver nucleic acid in the form of mRNA, the success of which would not be possible without biomaterials. Lipid nanoparticle (LNP)-based mRNA vaccines, discussed in this perspective, protect nucleic acids from degradation and deliver cargo directly to the intracellular compartment of cells where it is translated into the antigenic severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) spike protein that triggers protective immune responses. Despite success of LNP-based mRNA vaccines thus far, the pandemic has highlighted the need for emerging technologies that enable rapid development and increased accessibility to vaccination. Microneedle arrays, also discussed in this study, provide features that could lower barriers to vaccine access in resource-poor regions. The ability to exchange antigens within arrays could also facilitate swift vaccine deployment as public health needs evolve (e.g., in response to SARS-CoV-2 variants or entirely new pathogens). Therefore, the COVID-19 pandemic has spotlighted the readiness and value of biomaterials for the prevention and management of disease outbreaks.

Abstract
Patients with activated phosphatidylinositol 3-kinase delta (PI3Kδ) syndrome (APDS) present with sinopulmonary infections, lymphadenopathy, and cytomegalvirus (CMV) and/or Epstein-Barr virus (EBV) viremia, yet why patients fail to clear certain chronic viral infections remains incompletely understood. Using patient samples and a mouse model (Pik3cdE1020K/+ mice), we demonstrate that, upon activation, Pik3cdE1020K/+ CD8+ T cells exhibit exaggerated features of effector populations both in vitro and after viral infection that are associated with increased Fas-mediated apoptosis due to sustained FoxO1 phosphorylation and Fasl derepression, enhanced mTORC1 and c-Myc signatures, metabolic perturbations, and an altered chromatin landscape. Conversely, Pik3cdE1020K/+ CD8+ cells fail to sustain expression of proteins critical for central memory, including TCF1. Strikingly, activated Pik3cdE1020K/+ CD8+ cells exhibit altered transcriptional and epigenetic circuits characterized by pronounced interleukin-2 (IL-2)/STAT5 signatures and heightened IL-2 responses that prevent differentiation to memory-like cells in IL-15. Our data position PI3Kδ as integrating multiple signaling nodes that promote CD8+ T cell effector differentiation, providing insight into phenotypes of patients with APDS.

Abstract
Outcomes during immunotherapy are impacted not only by the specific therapeutic signals and pharmacodynamics, but also by the biophysical forms in which signals are delivered. This integration is determinative in autoimmunity because the disease is caused by immune dysregulation and inflammation. Unfortunately, the links between nanomaterial design, biophysical properties, and immune regulation are poorly defined. Here we designed cationic peptide antigens with defined charge distributions and then used electrostatics to assemble these peptides into complexes with anionic regulatory cues. We first show complexes induce antigen-specific tolerance during myelin-driven autoimmunity. We next show the affinity between these immune cues is controlled by charge balance and that affinity confers distinct biophysical properties important in immunological processing, including antigen availability. The underlying binding affinities between the self-assembled signals influences inflammatory gene expression in dendritic cells and antigen-specific regulatory outcomes in self-reactive transgenic T cells. This granular understanding of nanomaterial-immune interactions contributes to a more rational immunotherapy design.

Abstract
Autoimmune diseases like multiple sclerosis (MS), type 1 diabetes, and lupus occur when the immune system attacks host tissue. Immunotherapies that promote selective tolerance without suppressing normal immune function are of tremendous interest. Here, nanotechnology was used for rational assembly of peptides and modulatory immune cues into immune complexes. Complexes containing self-peptides and regulatory nucleic acids reverse established paralysis in a preclinical MS model. Importantly, mice responding to immunotherapy maintain healthy, antigen-specific B and T cell responses during a foreign antigen challenge. A therapeutic library isolating specific components reveals that regulatory nucleic acids suppress inflammatory genes in innate immune cells, while disease-matched peptide sequences control specificity of tolerance. Distinct gene expression profiles in cells and animals are associated with the immune signals administered in particulate and soluble forms, highlighting the impact of biophysical presentation of signals. This work provides insight into the rational manipulation of immune signaling to drive tolerance.

Abstract
Objective In individuals with mitochondrial disease, respiratory viral infection can result in metabolic decompensation with mitochondrial hepatopathy. Here, we used a mouse model of liver-specific Complex IV deficiency to study hepatic allostasis during respiratory viral infection. Methods Mice with hepatic cytochrome c oxidase deficiency (LivCox10−/−) were infected with aerosolized influenza, A/PR/8 (PR8), and euthanized on day five after infection following three days of symptoms. This time course is marked by a peak in inflammatory cytokines and mimics the timing of a common clinical scenario in which caregivers may first attempt to manage the illness at home before seeking medical attention. Metabolic decompensation and mitochondrial hepatopathy in mice were characterized by serum hepatic testing, histology, electron microscopy, biochemistry, metabolomics, and bioenergetic profiling. Results Following influenza infection, LivCox10−/− mice displayed marked liver disease including hepatitis, enlarged mitochondria with cristae loss, and hepatic steatosis. This pathophysiology was associated with viremia. Primary hepatocytes from LivCox10−/− mice cocultured with WT Kupffer cells in the presence of PR8 showed enhanced lipid accumulation. Treatment of hepatocytes with recombinant TNFα implicated Kupffer cell-derived TNFα as a precipitant of steatosis in LivCox10−/− mice. Eliminating Kupffer cells or blocking TNFα in vivo during influenza infection mitigated the steatosis and mitochondrial morphologic changes. Conclusions Taken together, our data shift the narrative of metabolic decompensation in mitochondrial hepatopathy beyond the bioenergetic costs of infection to include an underlying susceptibility to immune-mediated damage. Moreover, our work suggests that immune modulation during metabolic decompensation in mitochondrial disease represents a future viable treatment strategy needing further exploration. Influenza infection leads to worsening mitochondrial function and steatohepatitis in a model of mitochondrial hepatopathy. Kupffer cells may mediate this damage by the uptake of influenza virus and the secretion of TNFa. Hepatocytes affected by mitochondrial disease have a lower threshold for immune mediated toxicity by TNFa. Modulating the immune response leads to an improvement in the phenotype.

Abstract
Activated phosphoinositide 3-kinase delta syndrome (APDS), also known as p110 delta-activating mutation causing senescent T cells, lymphadenopathy and immunodeficiency (PASLI), is an autosomal dominant primary human immunodeficiency (PID) caused by heterozygous gain-of-function mutations in PIK3CD, which encodes the p110δ catalytic subunit of PI3K. This recently described PID is characterized by diverse and heterogeneous clinical manifestations that include recurrent respiratory infections, lymphoproliferation, progressive lymphopenia, and defective antibody responses. A major clinical manifestation observed in the NIH cohort of patients with PIK3CD mutations is chronic Epstein-Barr virus (EBV) and/or cytomegalovirus viremia. Despite uncontrolled EBV infection, many APDS/PASLI patients had normal or higher frequencies of EBV-specific CD8+ T cells. In this review, we discuss data pertaining to CD8+ T cell function in APDS/PASLI, including increased cell death, expression of exhaustion markers, and altered killing of autologous EBV-infected B cells, and how these and other data on PI3K provide insight into potential cellular defects that prevent clearance of chronic infections.

Abstract
Immunometabolism aims to define the role of intermediary metabolism in immune cell function, with bioenergetics and the mitochondria recently taking center stage. To date, the medical literature on mitochondria and immune function extols the virtues of mouse models in exploring this biologic intersection. While the laboratory mouse has become a standard for studying mammalian biology, this model comprises part of a comprehensive approach. Humans, with their broad array of inherited phenotypes, serve as a starting point for studying immunometabolism; specifically, patients with mitochondrial disease. Using this top-down approach, the mouse as a model organism facilitates further exploration of the consequences of mutations involved in mitochondrial maintenance and function. In this review, we will discuss the emerging phenotype of immune dysfunction in mitochondrial disease as a model for understanding the role of the mitochondria in immune function in available mouse models.

Abstract
Abstract
The catalytic p110δ subunit of PI3K drives AKT pathways orchestrating activation and differentiation of T and B cells. Patients with gain of function mutations in Pik3cd (encoding for p110δ) exhibit a primary immunodeficiency characterized by lymphopenia, lymphadenopathy, recurrent and chronic infections, and occasionally lymphoma. They have reduced circulating naïve and increased effector T cell numbers, fewer class switched memory B cells and inefficient responses to vaccination. Nonetheless, in patient peripheral blood we find increased frequencies of T follicular helper (Tfh) cells. We have generated a mouse model expressing constitutively active p110δ that recapitulates many features of the human disease. Pik3cdMut mice, both in steady state condition and after immunization, display increased Tfh and germinal center (GC) B cell numbers in secondary lymphoid organs. Moreover, naïve mutant transgenic T cells (OT-II) preferentially acquire Tfh cell phenotype when adoptively transferred to WT mice, indicative of a T cell intrinsic defect. Nonetheless, despite increased Tfh and GC B cells, antigen specific B cell responses are reduced, particularly antigen-specific IgG. In contrast, we find the appearance of autoantibodies in Pik3cdMut mice. We further find that mutant OT-2 cells differentiate to Tfh cells independently from ICOS-ICOSL interactions. In line with this, mutant T cells show higher phosphorylation and inactivation of FoxO1, potent inhibitor of Tfh cell differentiation, that is phosphorylated and inhibited by AKT activation downstream of ICOS. Our results demonstrate that hyperactivated PI3Kδ leads to increased generation of Tfh cells and germinal centers, yet with defective in vivo function.

Abstract
Patients with mutations in inducible T cell kinase (ITK) are susceptible to viral infections, particularly EBV, suggesting that these patients have defective function of CD8+ CTLs. In this study, we evaluated the effects of ITK deficiency on cytolysis in murine CTLs deficient in ITK, and both human and murine cells treated with an ITK inhibitor. We find that ITK deficiency leads to a global defect in the cytolysis of multiple targets. The absence of ITK both affected CTL expansion and delayed the expression of cytolytic effectors during activation. Furthermore, absence of ITK led to a previously unappreciated intrinsic defect in degranulation. Nonetheless, these defects could be overcome by early or prolonged exposure to IL-2, or by addition of IL-12 to cultures, revealing that cytokine signaling could restore the acquisition of effector function in ITK-deficient CD8+ T cells. Our results provide new insight into the effect of ITK and suboptimal TCR signaling on CD8+ T cell function, and how these may contribute to phenotypes associated with ITK deficiency.

Abstract
X-linked lymphoproliferative disease (XLP-1) is an often-fatal primary immunodeficiency associated with the exuberant expansion of activated CD8(+) T cells after Epstein-Barr virus (EBV) infection. XLP-1 is caused by defects in signaling lymphocytic activation molecule (SLAM)-associated protein (SAP), an adaptor protein that modulates T cell receptor (TCR)-induced signaling. SAP-deficient T cells exhibit impaired TCR restimulation-induced cell death (RICD) and diminished TCR-induced inhibition of diacylglycerol kinase α (DGKα), leading to increased diacylglycerol metabolism and decreased signaling through Ras and PKCθ (protein kinase Cθ). We show that down-regulation of DGKα activity in SAP-deficient T cells restores diacylglycerol signaling at the immune synapse and rescues RICD via induction of the proapoptotic proteins NUR77 and NOR1. Pharmacological inhibition of DGKα prevents the excessive CD8(+) T cell expansion and interferon-γ production that occur in SAP-deficient mice after lymphocytic choriomeningitis virus infection without impairing lytic activity. Collectively, these data highlight DGKα as a viable therapeutic target to reverse the life-threatening EBV-associated immunopathology that occurs in XLP-1 patients.

Abstract
BACKGROUND Tuberculosis (TB) remains a leading cause of morbidity and mortality worldwide, yet no new drugs have been developed in the last 40 years. OBJECTIVE The exceedingly lengthy TB chemotherapy and the increasing emergence of drug resistance complicated by HIV co-infection call for the development of new TB drugs. These problems are further compounded by a poor understanding of the biology of persister bacteria. METHODS New molecular tools have offered insights into potential new drug targets, particularly the enzymes of the shikimate pathway, which is the focus of this review. RESULTS/CONCLUSION Shikimate pathway enzymes, especially shikimate kinase, may offer attractive targets for new TB drug and vaccine development.

Abstract
Whole-body bioimaging was employed to study the effects of passive immunotherapies on lethality and viral dissemination in BALB/c mice challenged with recombinant vaccinia viruses expressing luciferase. WRvFire and IHD-J-Luc vaccinia viruses induced lethality with similar times to death following intranasal infection, but WRvFire replicated at higher levels than IHD-J-Luc in the upper and lower respiratory tracts. Three types of therapies were tested: licensed human anti-vaccinia virus immunoglobulin intravenous (VIGIV); recombinant anti-vaccinia virus immunoglobulin (rVIG; Symphogen, Denmark), an investigational product containing a mixture of 26 human monoclonal antibodies (HuMAbs) against mature virion (MV) and enveloped virion (EV); and HuMAb compositions targeting subsets of MV or EV proteins. Bioluminescence recorded daily showed that pretreatment with VIGIV (30 mg) or with rVIG (100 μg) on day -2 protected mice from death but did not prevent viral replication at the site of inoculation and dissemination to internal organs. Compositions containing HuMAbs against MV or EV proteins were protective in both infection models at 100 μg per animal, but at 30 μg, only anti-EV antibodies conferred protection. Importantly, the t statistic of the mean total fluxes revealed that viral loads in surviving mice were significantly reduced in at least 3 sites for 3 consecutive days (days 3 to 5) postchallenge, while significant reduction for 1 or 2 days in any individual site did not confer protection. Our data suggest that reduction of viral replication at multiple sites, including respiratory tract, spleen, and liver, as monitored by whole-body bioluminescence can be used to predict the effectiveness of passive immunotherapies in mouse models.
