In this study, we explored a novel therapeutic approach for the treatment of house dust mite allergen Der p 1induced asthma by aiming to eliminate specific population of B-cells involved in memory IgE response to Der p 1.Materials and methods: To achieve this aim, we developed and evaluated two different proDer p 1-based fusion proteins; an allergen-toxin (proDer p 1-ETA) and an allergen-drug conjugate (ADC) (proDer p 1-SNAP-AURIF) against Der p 1 reactive hybridomas as an in vitro model for Der p 1 reactive human B-cells. The strategy involved the use of proDer p 1 allergen as a cell-specific ligand to selectively deliver the bacterial protein toxin Pseudomonas exotoxin A (ETA) or the synthetic small molecule toxin Auristatin F (AURIF) into the cytosol of Der p 1 reactive cells for highly efficient cell killing.Results: As such, we demonstrated recombinant proDer p 1 fusion proteins were selectively bound by Der p 1 reactive hybridomas as well as primary IgG1+ B-cells from HDM-sensitized mice. The therapeutic potential of proDer p 1-ETA' and proDer p 1-SNAP-AURIF was confirmed by their selective cytotoxic activities on Der p 1 reactive hybridoma cells. The allergen-toxin demonstrated superior cytotoxic activity, with IC50 values in the single digit nanomolar value, compared to the ADC.Discussions: Altogether, the proof-of-concept experiments in this study provide a promising approach for the treatment of patients with house dust mite-driven allergic asthma.","PeriodicalId":73353,"journal":{"name":"Immunotherapy advances","volume":"3 1","pages":"ltac023"},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC9912260/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"10738268","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The HIC-Vac Annual Meeting (3rd and 4th November 2022) brought together stakeholders including researchers, ethicists, volunteers, policymakers, industry partners, and funders with a strong representation from low- and middle-income countries. The network enables sharing of research findings, especially in endemic regions. Discussions included pandemic preparedness and the role of human challenge to accelerate vaccine development during outbreak, with industry speakers emphasising the great utility of human challenge in vaccine development. Public consent, engagement, and participation in human challenge studies were addressed, along with the role of embedded social science and empirical studies to uncover social, ethical, and regulatory issues around human infection challenge studies. Study volunteers shared their experiences and motivations for participating in studies. This report summarises completed and ongoing human challenge studies across a variety of pathogens and demographics, and addresses other key issues discussed at the meeting.","PeriodicalId":73353,"journal":{"name":"Immunotherapy advances","volume":"28 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135447286","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}

TolDC therapy has demonstrated safety and efficacy in different experimental models of autoimmune disease, such as multiple sclerosis (MS), type 1 diabetes (T1D), and rheumatoid arthritis (RA). Moreover, data from phase I clinical trials have shown that therapy with tolDCs is safe and well tolerated by MS, T1D, and RA patients. Nevertheless, various parameters need to be optimized to increase tolDC efficacy. In this regard, one important parameter to be determined is the most appropriate route of administration. Several delivery routes, such as intravenous, subcutaneous, intraperitoneal, intradermal, intranodal, and intraarticular routes, have been used in experimental models as well as in phase I clinical trials. This review summarizes data obtained from preclinical and clinical studies of tolDC therapy in the treatment of MS, T1D, and RA and their animal models, as well as data from the context of cancer immunotherapy using mature peptide-loaded DC, and data from in vivo cell tracking experiments, to define the most appropriate route of tolDC administration in relation to the most feasible, safest, and effective therapeutic use.","PeriodicalId":73353,"journal":{"name":"Immunotherapy advances","volume":"3 1","pages":"ltad012"},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC10403757/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"10006351","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Therefore, understanding myeloid phagocytic responses to therapeutic antibodies is critical. Immunoglobulin Fc receptors and host characteristics were evaluated in phagocytosis of 3D-cultured CD20+ B-cell lymphoma (spheroids) treated with different anti-CD20 rituximab (RTX) monoclonal antibody isotypes. Monocytes from healthy donors of different ages and sexes were isolated, and their Fc receptors for IgG (FcγRI, FcγRIIa, FcγRIIIa) and IgA (FcαRI) were determined, as well as Fc receptor gene polymorphisms. Antibody-dependent phagocytosis was assessed using flow cytometry, confocal imaging, and Fc receptor blocking. RTX isotypes showed varying efficacy in stimulating the phagocytosis of spheroids. RTX-IgG3 proved to be the most efficient, followed by RTX-IgG1. Monocytes infiltrated RTX-treated spheroids at the periphery but migrated also into the core when stimulated with RTX-IgG3. Blocking FcγRI or FcγRIIa, but not FcγRIIIa, with antibodies inhibited RTX-IgG1 and RTX-IgG3-mediated phagocytosis. Monocytes from younger women demonstrated higher FcγRI and FcγRIIa levels compared to older women, while older men displayed increasing FcγRI and FcγRIIIa levels compared to younger men. Monocytes from younger women displayed greater phagocytic activity compared to older women, while older men had better IgG-mediated phagocytosis than younger men. Single Fc receptor levels, or FcγRIIa and FcγRIIIa genetic variants, had a low correlation with phagocytic intensity, likely as a result of multiple engagements of Fcreceptors for IgG-mediated phagocytosis. In conclusion, antibody isotype, Fc receptors, age, and sex influence tumor phagocytosis. This study exposes the relationship between host traits and the efficacy of therapeutic antibodies, providing insights into cancer immunotherapy treatment.","PeriodicalId":73353,"journal":{"name":"Immunotherapy advances","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135447896","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}
