These cells rapidly migrate to sites of inflammation or tissue injury, facilitating pathogen clearance and tissue repair. The chemotactic signaling network regulating neutrophil recruitment is complex and not fully understood, particularly regarding damage-associated molecular patterns (DAMPs). In our previous research, we identified NMI as a DAMP that activates dendritic cells and macrophages, amplifying inflammatory responses and contributing to both acute and chronic inflammation. In this study, we investigated the role of NMI in neutrophil recruitment. We purified and characterized a recombinant murine NMI protein, ensuring endotoxin removal while preserving biological activity. In vivo experiments demonstrated that NMI enhances neutrophil recruitment in both a murine air pouch model and an acute peritonitis model, mediated by macrophage-derived chemokines. In vitro assays revealed a concentration-dependent increase in neutrophil migration induced by NMI, facilitated by chemokine secretion and subsequent migration through the CXCR2 receptor. Importantly, we established that NMI activates chemokine expression via the NF-kappaB signaling pathway. These findings provide insights into the mechanisms of NMI-induced neutrophil migration, enhancing our understanding of neutrophil recruitment during inflammation.","PeriodicalId":501182,"journal":{"name":"bioRxiv - Immunology","volume":"54 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-09-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142252116","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Comparative analysis of neutralization data from the CATNAP database revealed a nuanced relationship between bnAb activity and Env conformational plasticity, with substantial epitope-specific variation of bnAb potency ranging from increased to decreased activity against open, neutralization-sensitive Env. To systematically investigate the impact of Env conformational dynamics on bnAb potency we screened 126 JR-CSF point mutants for generalized neutralization sensitivity to weak-nAbs and plasma from people with chronic HIV-1 infection. 23 mutations at highly conserved sites resulted in neutralization phenotype with high Tier 1 sensitivity, which was associated with de-stabilization of the closed, prefusion conformation. Including 19 of these mutants into a Sensitivity Env mutant panel (SENSE-19), we classified bnAbs according to potency variations in response to trimer opening. To verify that these sensitivity patterns are independent of the in vitro assay system, replication-competent SENSE-19 mutant viruses were tested on primary CD4 T cells. While loss of potency on SENSE-19 was registered for bnAbs recognizing quaternary epitopes on pre-triggered Env, structural destabilization benefitted MPER bnAbs and other inhibitors known to have post-CD4 attachment neutralization activity. Importantly, for certain bnAbs targeting CD4bs, V3-glycan and interface epitopes, particularly low potency variation was noted, suggesting that Env conformational tolerance can be achieved but is not the rule. In summary, SENSE-19 screens revealed distinct Env flexibility tolerance levels between bnAb types that provide mechanistic insights in their function and broaden current neutralization breadth assessments.","PeriodicalId":501182,"journal":{"name":"bioRxiv - Immunology","volume":"192 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-09-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142252112","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In the present study, we investigated the potential of IL-27 neutralization to modify macrophage polarization and thus the tumor immune microenvironment.\u0000Methods and Analysis\u0000We monitored the effect of IL-27 neutralization on human macrophages. Flow cytometry, quantitative reverse transcription-PCR, ELISA and western blot were performed to validate, in vitro, the role of IL-27 on the acquisition of macrophage immunoregulatory functions. A murine Colon Adenocarcinoma model (MC38) was used to assess IL-27 neutralization in the microenvironment in vivo.\u0000Results\u0000In this study, we demonstrated the importance of IL-27 in the generation of human immunoregulatory macrophages. Mechanistically, IL-27 neutralization reduced the immunosuppressive properties of macrophages, such as cytokine secretion and membrane expression of immunosuppressive molecules. These modifications led to a reduction in the ability of macrophages to inhibit the function of CD4+ and CD8+ T cells. Furthermore, in vivo neutralization of IL-27 reduced MC38 tumor growth and could improve immune checkpoint inhibitor efficacy.\u0000Conclusions\u0000Collectively, we uncovered the role of IL-27 in the immunosuppressive tumor microenvironment (TME). We showed that IL-27 could be a target for macrophage repolarization and boosting of CD4+ and CD8+ T cell responses. IL-27 neutralization thus appears as a promising strategy to target macrophages in immunosuppressive TME and improve the clinical efficacy of immunotherapy protocols.","PeriodicalId":501182,"journal":{"name":"bioRxiv - Immunology","volume":"20 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-09-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142252110","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The immune system plays a crucial role in maintaining bone homeostasis and combating the development of osteoporosis. Immunoporosis is the term used to describe the recent convergence of research on the immune system's role in osteoporosis. Gut harbors the largest component of the immune system and there is growing evidence that intestinal immunity plays a vital role in regulating bone health. Gut-resident regulatory T cells (GTregs) play an essential role in inhibiting immune responses and preventing various inflammatory manifestations. Our findings show that GTregs have a pivotal role in the pathophysiology of post-menopausal osteoporosis (PMO). We investigated the potential of GTregs in regulating the development of bone cells in vitro. We observed that GTregs significantly enhance osteoblastogenesis with concomitant inhibition of osteoclastogenesis in a cell-ratio-dependent manner. We further report that the deficiency of short-chain fatty acids (SCFAs) in osteoporotic conditions substantially disrupts the composition of GTregs, leading to a loss of peripherally derived Tregs (pTregs) and an expansion of thymus-derived Tregs (tTregs). Moreover, the administration of probiotics Lactobacillus rhamnosus and Bifidobacterium longum modulated the GTregs compartment in an SCFA-dependent manner to mitigate inflammatory bone loss in PMO. Notably, SCFAs-primed GTregs were found to be significantly more effective in inhibiting osteoclastogenesis compared to unprimed GTregs. Altogether our results, for the first time, highlight the crucial role of GTregs in the pathophysiology of PMO, with potential clinical implications in the near future.","PeriodicalId":501182,"journal":{"name":"bioRxiv - Immunology","volume":"40 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-09-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142252109","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Optimum management of TB (particularly latent or MDR cases) warrants use of immunological approaches like subunit or peptide-based vaccination for tailoring effector immunity in patients. Since MHC class I is a potent enhancer element of host immunity and effective in clearing large variety of intracellular pathogens or tumors. In this context, we explore whether MHC-I restricted peptides from clinical isolates of M. tuberculosis can be used as an adjuvant for augmenting host immune responses. In the present study, we have synthesized various peptides from clinical isolates of M. tuberculosis which were having high affinity for Class I MHC molecules as potential immune enhancer for T cell or iNKT cell populations. We have evaluated the immunogenic potential of various MHC class I restricted epitopes (Rv2588c, Rv1357, Rv0148, Rv2973, Rv2557 and Rv2445) which were derived from clinical isolates of M. tuberculosis on increased proliferation of T or iNKT cells, release of IFN gamma secreted by T cells as well as NO as indicative parameters of immuno-stimulation. As expected, FACS and ELISA data clearly revealed that these peptides were potentially immunogenic for PBMCs from both healthy as well as 10 HC PTB patients. Our data clearly demonstrated a significant immune response in the PBMC from w PTB patients over healthy individuals which mimicked booster response. Our cytokine and nitric oxide data further revealed the influence of these peptides on sensitizing innate immune response as well.","PeriodicalId":501182,"journal":{"name":"bioRxiv - Immunology","volume":"141 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-09-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142268665","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study investigated the impact of common, acute viral infections prior to disease onset on ALS progression in the SOD1G93A mouse model. A single sublethal infection prior to onset of ALS clinical signs was associated with markedly accelerated ALS disease progression characterized by rapid loss of hindlimb function. Prior infection resulted in gliosis in the lumbar spine and upregulation of transcriptional pathways involved in inflammatory responses, metabolic dysregulation, and muscular dysfunction. Therapeutic suppression of gliosis with an anti-inflammatory small molecule, or administration of a direct-acting antiviral, was associated with significantly improved ALS clinical signs, akin to what was observed in uninfected animals. This study provides causal and mechanistic evidence that the immune response elicited by acute viral infections may be an important etiological factor that alters ALS disease trajectory, and provides insight into novel therapeutic and preventative strategies for ALS.","PeriodicalId":501182,"journal":{"name":"bioRxiv - Immunology","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-09-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142268661","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The nuclear factor (NF)-kB-dependent Toll pathway is a major regulator of innate immunity in insects. In mosquitoes, this pathway controls transcription of the majority of the known canonical humoral immune effectors, mediates anti-bacterial, anti-fungal and anti-viral immune responses, and contributes to malaria parasite killing. However, besides initial gene annotation of putative Toll pathway members and genetic analysis of the contribution of few key components to immunity, the molecular make-up and function of the Toll pathway in mosquitoes is largely unexplored. To facilitate functional analyses of the Toll pathway in mosquitoes, we report here manually annotated and refined gene models of Toll-like receptors and all putative components of the intracellular signal transduction cascade across 19 anopheline genomes, and in two culicine genomes. In addition, based on phylogenetic analyses, we identified differing levels of evolutionary constraint across the intracellular Toll pathway members, and identified a recent radiation of TOLL1/5 within the An. gambiae complex. Together, this study provides insight into the evolution of TLRs and the putative members of the intracellular signal transduction cascade within the genus Anopheles.","PeriodicalId":501182,"journal":{"name":"bioRxiv - Immunology","volume":"6 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-09-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142252114","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

With time, the Severe acute respiratory syndrome coronavirus 2 (SARS-COV-2) is also constantly mutating. Mutations lead to stronger infectivity or virulence of the virus, and some monoclonal antibodies against wild-type SARS-COV-2 are also challenging to play a role. Amubarvimab and Romlusevimab were originally developed against wild-type SARS-COV-2; however, these monoclonal antibodies' neutralizing efficacy and mechanism against these mutants are unknown. In this study, the binding ability of Amubarvimab and Romlusevimab to 7 mutant strains were tested by computer method and the interaction mechanism was explored. Our experimental data show that Amubarvimab can effectively bind most mutations and maintain the stability of the complexes mainly through hydrogen bond interaction; However, the binding efficiency of Romlusevimab was lower than that of Amubarvimab, and the stability of 18 the complexes was maintained mainly through electrostatic interaction. Both Amubarvimab and Romlusevimab show low binding potency against E406W and Q498Y mutations, so there is a certain probability of immune escape in the face of variants carrying E406W and Q498Y mutations when Amubarvimab and Romlusevimab are used in combination.","PeriodicalId":501182,"journal":{"name":"bioRxiv - Immunology","volume":"7 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-09-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142252121","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This pandemic outbreak was driven by the MPXV variant Clade IIb. In addition, Clade I viruses circulating in the Democratic Republic of Congo (DRC) are drawing increased attention as cases constantly rise and Clade Ib, first identified in 2023, is now co-circulating with Clade Ia and seems to exhibit enhanced human-to-human transmissibility. While most infected individuals display a self-limiting disease with singular pox-like lesions, some endure systemic viral spread leading to whole-body rash with risks for necrosis, organ loss, and death. Intra-host dissemination and cellular tropism of MPXV are largely unexplored in humans. To establish a potential susceptibility of circulating immune cells to MPXV, we exposed human PBMCs from healthy donors ex vivo to a currently circulating MPXV clade IIb virus isolate in absence and presence of IFN-α2a. qPCR of DNA extracted from cell lysates, but less from supernatants, revealed increasing MPXV DNA quantities that peaked at five to six days post-exposure, suggesting susceptibility of PBMCs to infection. IFN-α2a pretreatment markedly reduced the quantity of MPXV DNA, suggesting that infection is sensitive to type I IFNs. Plaque assays from supernatants showed that infection gave rise to de novo production of infectious MPXV. In virus-inclusive scRNA-sequencing, monocytes, cycling NK cells and regulatory CD4+ T-cells scored positive for viral RNA, suggesting that these are the MPXV-susceptible cell types within the human PBMC population. Analysis of differentially expressed genes displayed a pronounced downregulation of expression pathways driving innate immunity in MPXV-infected cells, a well-established feature of poxviral infection. Pretreatment of PBMCs with current antivirals Cidofovir and Tecovirimat resulted in reduced amounts of viral antigen production and of released infectivity, suggesting suitability of the human PBMC infection model as a platform for evaluation of current and future antivirals and justifying trials to investigate Cidofovir and Tecovirimat as drugs reducing intra-patient viral spread. Together, our data suggest that human PBMCs are productively infected by MPXV which is accompanied by significant modulation of the cellular milieu. Our results have the potential to illuminate aspects of intra-host propagation of MPXV that may involve a lymphohematogenous route for replication and/or intra-host dissemination.","PeriodicalId":501182,"journal":{"name":"bioRxiv - Immunology","volume":"54 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-09-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142252115","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
