Abstract
CCR5 is among the most studied chemokine receptors due to its profound significance in human health and disease. The notion that CCR5 is a functionally redundant receptor was challenged through the demonstration of its unique protective role in the context of West Nile virus in both mice and humans. In the nearly two decades since this initial discovery, numerous studies have investigated the role of CCR5 in the context of other medically important neurotropic flaviviruses, most of which appear to support a broad neuroprotective role for this receptor, although how CCR5 exerts its protective effect has been remarkably varied. In this review, we summarize the mechanisms by which CCR5 controls neurotropic flaviviruses, as well as results from human studies evaluating a genetic link to CCR5, and propose unexplored areas of research that are needed to unveil even more exciting roles for this important receptor.

Innate and adaptive immune gene expression in the brain is associated with neuropathological changes after infection with bovine alpha-herpesvirus-5 in mice. Vet Microbiol 2023; 285:109845. [PMID: 37634288 DOI: 10.1016/j.vetmic.2023.109845] [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: 03/29/2023] [Revised: 08/04/2023] [Accepted: 08/07/2023] [Indexed: 08/29/2023]
Abstract
Bovine alpha herpesvirus-5 (BoAHV-5) is related to the development of meningoencephalitis in cattle. Very little is known about the molecular pathways involved in the central nervous system (CNS) damage associated with inflammation during BoHV-5 infection in mice. To better identify the specific immunological pathways triggered by BoAHV-5 infection in mice, we evaluated the mRNA expression of 84 genes involved in innate and adaptive immune responses. We compared gene expression changes in the cerebrum from noninfected and infected mice with BoHV-5 at a 1 × 107 TCID50. Then, we analyzed the association of these genes with neurological signs, neuropathology, and activation of glial cells in response to BoHV-5 infection. Three days after BoAHV-5 infection, increased expression of TNF, IL-2, CXCL10, CXCR3, CCR4, CCL5, IFN-γ, IL-10, IRF7, STAT1, MX1, GATA 3 C3, LIZ2, caspase-1 and IL-1b was found. We also observed the upregulated expression of the CD8a, TBX21 and CD40LG genes and the downregulated expression of the CD4 gene after BoAHV-5 infection. In addition, BoHV-5-infected animals showed higher levels of all the evaluated inflammatory mediators (TNF, IFN-γ and IL-10) on day 3 postinfection. BoAHV-5-infected animals showed neurological changes along with meningoencephalitis, neuropil vacuolation, hemorrhage and reactive gliosis. Astrogliosis and microgliosis, indicated by increased expression of glial fibrillary acidic protein (GFAP) and ionized calcium-binding adapter molecule 1 (Iba-1), were found throughout the neuropil in infected brains. Moreover, cleaved caspase-3 immunopositive glio-inflammatory cells were visualized around some blood vessels in areas of neuroinflammation in the cerebrum. In agreement on that we found higher cleaved caspase-3 and Iba-1 expression evaluated by western blot analysis in the brains of infected mice compared to control mice. In conclusion, our results revealed.

Low avidity circulating SARS-CoV-2 reactive CD8+ T cells with proinflammatory TEMRA phenotype are associated with post-acute sequelae of COVID-19. Front Microbiol 2023; 14:1196721. [PMID: 37333646 PMCID: PMC10272838 DOI: 10.3389/fmicb.2023.1196721] [Citation(s) in RCA: 3] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/30/2023] [Accepted: 05/16/2023] [Indexed: 06/20/2023] Open
Abstract
The role of adaptive SARS-CoV-2 specific immunity in post-acute sequelae of COVID-19 (PASC) is not well explored, although a growing population of convalescent COVID-19 patients with manifestation of PASC is observed. We analyzed the SARS-CoV-2-specific immune response, via pseudovirus neutralizing assay and multiparametric flow cytometry in 40 post-acute sequelae of COVID-19 patients with non-specific PASC manifestation and 15 COVID-19 convalescent healthy donors. Although frequencies of SARS-CoV-2-reactive CD4+ T cells were similar between the studied cohorts, a stronger SARS-CoV-2 reactive CD8+ T cell response, characterized by IFNγ production and predominant TEMRA phenotype but low functional TCR avidity was detected in PASC patients compared to controls. Of interest, high avidity SARS-CoV-2-reactive CD4+ and CD8+ T cells were comparable between the groups demonstrating sufficient cellular antiviral response in PASC. In line with the cellular immunity, neutralizing capacity in PASC patients was not inferior compared to controls. In conclusion, our data suggest that PASC may be driven by an inflammatory response triggered by an expanded population of low avidity SARS-CoV-2 reactive pro-inflammatory CD8+ T cells. These pro-inflammatory T cells with TEMRA phenotype are known to be activated by a low or even without TCR stimulation and lead to a tissue damage. Further studies including animal models are required for a better understanding of underlying immunopathogensis. Summary: A CD8+ driven persistent inflammatory response triggered by SARS-CoV-2 may be responsible for the observed sequelae in PASC patients.

Abstract
BACKGROUND & AIMS The stroma in pancreatic ductal adenocarcinoma (PDAC) contributes to its immunosuppressive nature and therapeutic resistance. Herein we sought to modify signaling and enhance immunotherapy efficacy by targeting multiple stromal components through both intracellular and extracellular mechanisms. METHODS A murine liver metastasis syngeneic model of PDAC was treated with focal adhesion kinase inhibitor (FAKi), anti-programmed cell death protein 1 (PD-1) antibody, and stromal hyaluronan (HA) degradation by PEGylated recombinant human hyaluronidase (PEGPH20) to assess immune and stromal modulating effects of these agents and their combinations. RESULTS The results showed that HA degradation by PEGPH20 and reduction in phosphorylated FAK expression by FAKi leads to improved survival in PDAC-bearing mice treated with anti-PD-1 antibody. HA degradation in combination with FAKi and anti-PD-1 antibody increases T-cell infiltration and alters T-cell phenotype toward effector memory T cells. FAKi alters the expression of T-cell modulating cytokines and leads to changes in T-cell metabolism and increases in effector T-cell signatures. HA degradation in combination with anti-PD-1 antibody and FAKi treatments reduces granulocytes, including granulocytic- myeloid-derived suppressor cells and decreases C-X-C chemokine receptor type 4 (CXCR4)-expressing myeloid cells, particularly the CXCR4-expressing granulocytes. Anti-CXCR4 antibody combined with FAKi and anti-PD-1 antibody significantly decreases metastatic rates in the PDAC liver metastasis model. CONCLUSIONS This represents the first preclinical study to identify synergistic effects of targeting both intracellular and extracellular components within the PDAC stroma and supports testing anti-CXCR4 antibody in combination with FAKi as a PDAC treatment strategy.

Abstract
ObjectivesBesides CD4 regulatory T-cells (Tregs), immunosuppressor FoxP3+ CD8 T-cells are emerging as an important subset of Tregs, which contribute to immune dysfunction and disease progression in HIV infection. However, FoxP3+ CD8 T-cell dynamics in acute HIV infection and following early antiretroviral therapy (ART) initiation remain understudied.MethodsSubsets of FoxP3+ CD8 T-cells were characterized both prospectively and cross-sectionally in PBMCs from untreated acute (n=26) and chronic (n=10) HIV-infected individuals, early ART-treated in acute infection (n=10, median of ART initiation: 5.5 months post-infection), ART-treated in chronic infection (n=10), elite controllers (n=18), and HIV-uninfected controls (n=21).ResultsAcute and chronic infection were associated with increased total, effector memory, and terminally differentiated FoxP3+ CD8 T-cells, while early ART normalized only the frequencies of total FoxP3+ CD8 T-cells. We observed an increase in FoxP3+ CD8 T-cell immune activation (HLADR+/CD38+), senescence (CD57+/CD28-), and PD-1 expression during acute and chronic infection, which were not normalized by early ART. FoxP3+ CD8 T-cells in untreated participants expressed higher levels of immunosuppressive LAP(TGF-β1) and CD39 than uninfected controls, whereas early ART did not affect their expression. The expression of gut-homing markers CCR9 and Integrin-β7 by total FoxP3+ CD8 T-cells and CD39+ and LAP(TGF-β1)+ FoxP3+ CD8 T-cells increased in untreated individuals and remained higher than in uninfected controls despite early ART. Elite controllers share most of the FoxP3+ CD8 T-cell characteristics in uninfected individuals.ConclusionsAlthough early ART normalized total FoxP3+ CD8 T-cells frequencies, it did not affect the persistent elevation of the gut-homing potential of CD39+ and LAP(TGF-β1)+ FoxP3+ CD8 T-cell, which may contribute to immune dysfunction.

Lenvatinib enhances T cell immunity and the efficacy of adoptive chimeric antigen receptor-modified T cells by decreasing myeloid-derived suppressor cells in cancer. Pharmacol Res 2021; 174:105829.

Abstract
BACKGROUND Lenvatinib, a tyrosine kinase inhibitor, has been approved for the treatment of several cancers. However, its regulatory activity and related mechanisms on T cell antitumour immunity need to be further investigated. METHODS The antitumour activity of lenvatinib in immunocompetent and immunodeficient mice was compared to determine the role of T cell immunity. The antitumour activity of T cells was analysed by cytokine production and adoptive T cell therapy. The immunosuppressive effects of MDSCs on T cells were determined by detecting cytokine production in T cells after being cocultured with MDSCs. The adjuvant immunotherapy effect of lenvatinib was determined by combination therapy with CAR-T cells targeted carbonic anhydrase IX (CAIX) in a murine renal cancer model. RESULTS The antitumour activity of lenvatinib was greater in immunocompetent mice than in immunodeficient mice and was attenuated by CD8+T cell depletion. Lenvatinib increased proliferation, tumour infiltration and antitumour activity of T cells. Importantly, adoptive transfer of lenvatinib-treated T cells showed a long-term antitumour response in vivo. Mechanistically, lenvatinib upregulated T cell-related chemokines (CXCL10 and CCL8) in tumours and decreased the frequency and immunosuppressive activity of MDSCs. Furthermore, lenvatinib enhanced the efficacy of CAR-T cells in a murine renal cancer model. CONCLUSION Our study revealed novel antitumour mechanisms of lenvatinib by enhancing T cell-mediated antitumour immunity. These findings are of great significance for guiding the clinical use of lenvatinib and provide a good candidate for future combination therapy with T-cell therapies or other immunotherapies.

Abstract
Ocular HSV-1 infection is a major cause of eye disease and innate and adaptive immunity both play a role in protection and pathology associated with ocular infection. Previously we have shown that M1-type macrophages are the major and earliest infiltrates into the cornea of infected mice. We also showed that HSV-1 infectivity in the presence and absence of M2-macrophages was similar to wild-type (WT) control mice. However, it is not clear whether the absence of M1 macrophages plays a role in protection and disease in HSV-1 infected mice. To explore the role of M1 macrophages in HSV-1 infection, we used mice lacking M1 activation (M1-/- mice). Our results showed that macrophages from M1-/- mice were more susceptible to HSV-1 infection in vitro than were macrophages from WT mice. M1-/- mice were highly susceptible to ocular infection with virulent HSV-1 strain McKrae, while WT mice were refractory to infection. In addition, M1-/- mice had higher virus titers in the eyes than did WT mice. Adoptive transfer of M1 macrophages from WT mice to M1-/- mice reduced death and rescued virus replication in the eyes of infected mice. Infection of M1-/- mice with avirulent HSV-1 strain KOS also increased ocular virus replication and eye disease but did not affect latency-reactivation seen in WT control mice. Severity of virus replication and eye disease correlated with significantly higher inflammatory responses leading to a cytokine storm in the eyes of M1-/- infected mice that was not seen in WT mice. Thus, for the first time, our study illustrates the importance of M1 macrophages specifically in primary HSV-1 infection, eye disease, and survival but not in latency-reactivation. Macrophages circulating in the blood or present in different tissues constitute an important barrier against infection. We previously showed that the absence of M2 macrophages does not impact HSV-1 infectivity in vivo. However, in this study we demonstrated an essential role of M1 macrophages in protection from primary HSV-1 replication, death, and eye disease but not in latency-reactivation.
