Abstract
Acute myeloid leukemia (AML) is a clonal hematopoietic stem and progenitor cell malignancy characterized by poor clinical outcomes. Major histocompatibility complex class I polypeptide-related sequence A and B (MICA/B) are stress proteins expressed by cancer cells, and antibody-mediated inhibition of MICA/B shedding represents a novel approach to stimulate immunity against cancers. We found that the MICA/B antibody 7C6 potently inhibits the outgrowth of AML in 2 models in immunocompetent mice. Macrophages were essential for therapeutic efficacy, and 7C6 triggered antibody-dependent phagocytosis of AML cells. Furthermore, we found that romidepsin, a selective histone deacetylase inhibitor, increased MICB messenger RNA in AML cells and enabled subsequent stabilization of the translated protein by 7C6. This drug combination substantially increased surface MICA/B expression in a human AML line, pluripotent stem cell-derived AML blasts and leukemia stem cells, as well as primary cells from 3 untreated patients with AML. Human macrophages phagocytosed AML cells following treatment with 7C6 and romidepsin, and the combination therapy lowered leukemia burden in a humanized model of AML. Therefore, inhibition of MICA/B shedding promotes macrophage-driven immunity against AML via Fc receptor signaling and synergizes with an epigenetic regulator. These results provide the rationale for the clinical testing of this innovative immunotherapeutic approach for the treatment of AML.

Microb Pathog 2020; 150:104684. [PMID: 33301858 DOI: 10.1016/j.micpath.2020.104684] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/14/2020] [Revised: 12/03/2020] [Accepted: 12/04/2020] [Indexed: 11/15/2022]
Abstract
Autoimmunity can potentially pre-dispose to, exacerbate or ameliorate pathogenic infections. The current study was designed to compare and understand the infection outcomes with Salmonella enterica serovar Typhimurium ATCC 14028s (S. Typhimurium) wild type (WT) and attenuated ΔrpoS strains, in autoimmune-prone lpr mice. C57BL/6 (B6) and B6/lpr (lpr) 6-8 weeks old mice were orally infected with S. Typhimurium WT and ΔrpoS strains. Disease outcomes were assessed with respect to survival, organ bacterial load, tissue damage and inflammation in infected mice. The acute infection stage (day 4) was examined and compared to the later stages (up to day 12) post ΔrpoS infection. S. Typhimurium WT exhibited an acute and lethal infection in both B6 and lpr mice. However, the ΔrpoS strain exhibited prolonged infection with reduced mortality in B6 mice but complete mortality in lpr mice. During late infection, bacterial load and serum IFNγ levels were higher in the ΔrpoS strain infected lpr mice compared to B6 mice. The ΔrpoS strain infected lpr mice also exhibited greater bacterial faecal shedding and greater tissue histopathological changes. Interestingly, ΔrpoS-infected B6 mice displayed minimal microbial load in the brain; however, sustained brain bacterial load was observed in ΔrpoS-infected lpr mice, corresponding to abnormal gait. Overall, S. Typhimurium ΔrpoS is competent in establishing infection but compromised in sustaining it. Nonetheless, lpr mice are less efficient in controlling this attenuated infection. The findings from the study demonstrate that genetic pre-disposition to autoimmunity is sufficient for greater host susceptibility to infection by attenuated S. Typhimurium strains.

A lack of Fas/FasL signalling leads to disturbances in the antiviral response during ectromelia virus infection. Arch Virol 2016; 161:913-28.

Abstract
Ectromelia virus (ECTV) is an orthopoxvirus (OPV) that causes mousepox, the murine equivalent of human smallpox. Fas receptor-Fas ligand (FasL) signaling is involved in apoptosis of immune cells and virus-specific cytotoxicity. The Fas/FasL pathway also plays an important role in controlling the local inflammatory response during ECTV infection. Here, the immune response to the ECTV Moscow strain was examined in Fas (-) (lpr), FasL (-) (gld) and C57BL6 wild-type mice. During ECTV-MOS infection, Fas- and FasL mice showed increased viral titers, decreased total numbers of NK cells, CD4(+) and CD8(+) T cells followed by decreased percentages of IFN-γ expressing NK cells, CD4(+) and CD8(+) T cells in spleens and lymph nodes. At day 7 of ECTV-MOS infection, Fas- and FasL-deficient mice had the highest regulatory T cell (Treg) counts in spleen and lymph nodes in contrast to wild-type mice. Furthermore, at days 7 and 10 of the infection, we observed significantly higher numbers of PD-L1-expressing dendritic cells in Fas (-) and FasL (-) mice in comparison to wild-type mice. Experiments in co-cultures of CD4(+) T cells and bone-marrow-derived dendritic cells showed that the lack of bilateral Fas-FasL signalling led to expansion of Tregs. In conclusion, our results demonstrate that during ECTV infection, Fas/FasL can regulate development of tolerogenic DCs and Tregs, leading to an ineffective immune response.

Abstract
Programmed cell death is an integral part of host defense against invading intracellular pathogens. Apoptosis, programmed necrosis, and pyroptosis each serve to limit pathogen replication in infected cells, while simultaneously promoting the inflammatory and innate responses that shape effective long-term host immunity. The importance of carefully regulated cell death is evident in the spectrum of inflammatory and autoimmune disorders caused by defects in these pathways. Moreover, many viruses encode inhibitors of programmed cell death to subvert these host responses during infection, thereby facilitating their own replication and persistence. Thus, as both virus and cell vie for control of these pathways, the battle for survival has shaped a complex host-pathogen interaction. This review will discuss the multifaceted role that programmed cell death plays in maintaining the immune system and its critical function in host defense, with a special emphasis on viral infections.

Abstract
CD8 T cells are a key component of immunity to many viral infections. They achieve this through using an array of effector mechanisms, but precisely which component/s are required for protection against a respiratory orthopox virus infection remains unclear. Using a model of respiratory vaccinia virus infection in mice, we could specifically determine the relative contribution of perforin, TRAIL, and IFN-γ-mediated pathways in protection against virus induced morbidity and mortality. Unexpectedly, we observed that protection against death was mediated by IFN-γ without any involvement of the perforin or TRAIL-dependent pathways. IFN-γ mRNA and protein levels in the lung peaked between days 3 and 6 postinfection. This enhanced response coincided with the emergence of virus-specific CD8 T cells in the lung and the cessation of weight loss. Transfer experiments indicated that CD8 T cell-autonomous expression of IFN-γ restricts virus-induced lung pathology and dissemination to visceral tissues and is necessary for clearance of virus. Most significantly, we show that CD8 T cell-derived IFN-γ is sufficient to protect mice in the absence of CD4 and B-lymphocytes. Thus, our findings reveal a previously unappreciated mechanism by which effector CD8 T cells afford protection against a highly virulent respiratory orthopox virus infection.

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.
