Immunological enhancement of micro-nanoparticle formulated with risedronate and zinc as vaccine adjuvant in aged mice.
Background: Elderly individuals face heightened susceptibility to infectious diseases and diminished vaccine responses. Vaccine adjuvants offer a solution. Despite aluminum adjuvant's long history, its limitations in inducing strong cellular immunity and protecting immunocompromised individuals restrict its application. Building upon our previous development of zinc salt particle-based risedronate (Zn-RS), we systematically investigated the immunoenhancing effects of Zn-RS in aged mice and thoroughly explored the underlying mechanisms responsible for these observations in this study.
Results: Compared to formulations using aluminum adjuvant, Zn-RS combined with either varicella-zoster virus glycoprotein E (gE) or SARS-CoV-2 monovalent STFK protein (STFK) elicited significantly higher IgG and neutralization titers, as well as superior long-term humoral immunity. Moreover, Zn-RS induced greater quantities of dendritic cells (DCs), antigen-presenting cells (APCs), follicular helper T (TFH) cells, Th1/Th2/Th9/Th17 type immune cells, germinal center B cells (GCBs) and plasma cells.
Conclusions: These findings support Zn-RS as a promising adjuvant candidate for elderly populations, warranting further exploration of its mechanisms and potential applications.
期刊介绍:
Immunity & Ageing is a specialist open access journal that was first published in 2004. The journal focuses on the impact of ageing on immune systems, the influence of aged immune systems on organismal well-being and longevity, age-associated diseases with immune etiology, and potential immune interventions to increase health span. All articles published in Immunity & Ageing are indexed in the following databases: Biological Abstracts, BIOSIS, CAS, Citebase, DOAJ, Embase, Google Scholar, Journal Citation Reports/Science Edition, OAIster, PubMed, PubMed Central, Science Citation Index Expanded, SCImago, Scopus, SOCOLAR, and Zetoc.
