The multiple-dose regimens, along with the high production costs of current rabies vaccines, limit their use in rabies-endemic countries with developing economies and consequently there is a need for new efficacious, low-cost rabies vaccines. This study investigates the immunogenicity of recombinant rabies virus glycoprotein (rRABVG), expressed in the yeast Komagataella phaffii (K. phaffii), as a candidate subunit rabies vaccine.METHODSMonoclonal antibodies were used to confirm neutralizing epitopes presence on the rRABVG. The rRABVG potency was estimated by antigen quantification methods using ELISA and SRID. Serological methods, specifically ELISA and RFFIT, were applied to investigate the immune response of mice groups immunized with rRABVG varying doses, with or without adjuvant.RESULTSThe potency estimated by antigen quantification was dependent on the method employed. Active immunization assessment using ELISA was effective when the solid-phase antigen is the rRABVG. The RFFIT data indicated that a single adjuvanted dose of 20 µg rRABVG is sufficient for virus-neutralizing antibodies induction at a protective level of 0.5 IU/mL within 10 days post immunization.CONCLUSIONThese data demonstrate that K. phaffii produced rRABVG is immunoactive and could be an attractive candidate to develop a low-cost subunit rabies vaccine.","PeriodicalId":13387,"journal":{"name":"Immunological Investigations","volume":"57 1","pages":"1-22"},"PeriodicalIF":2.8,"publicationDate":"2024-09-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142216585","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Several etiological theories are described in literature. Firstly, it is suggested that the gut plays an important role in the translocation of microbial products to the systemic circulation. Additionally, the production of autoantibodies that develop after the initial infection with SARS-CoV-2 might lead to many of its broad clinical symptoms. Finally, the superantigen theory where non-specific binding of the SARS-CoV-2 spike glycoprotein to the T-cell receptor leads to a subsequent activation of T cells, generating a powerful immune response. Despite the sudden outbreak of MIS-C and alarming messages, as of 2024, cases have declined drastically and subsequently show a less severe clinical spectrum.

The traditional classification of microglia as ramified, M1 (proinflammatory), or M2 (anti-inflammatory) phenotypes is overly simplistic, failing to capture the wide range of recently identified microglial phenotypes in various brain regions affected by neurodegenerative diseases. Altered and activated microglial phenotypes deviating from the typical ramified structure are significant features of many neurodegenerative conditions. Understanding the precise role of each microglial phenotype is intricate and sometimes contradictory. This review specifically focuses on elucidating recent modifications in microglial phenotypes within neurodegenerative diseases.
