Abstract
Messenger RNA (mRNA) vaccines against infectious diseases and for anticancer immunotherapy have garnered considerable attention. Currently, mRNA vaccines encapsulated in lipid nanoparticles are administrated via intramuscular injection using a needle. However, such administration is associated with pain, needle phobia, and lack of patient compliance. Furthermore, side effects such as fever and anaphylaxis associated with the lipid nanoparticle components are also serious problems. Therefore, noninvasive, painless administration of mRNA vaccines that do not contain other problematic components is highly desirable. Antigen-presenting cells reside in the epidermis and dermis, making the skin an attractive vaccination site. Iontophoresis (ItP) uses weak electric current applied to the skin surface and offers a noninvasive permeation technology that enables intradermal delivery of hydrophilic and ionic substances. ItP-mediated intradermal delivery of biological macromolecules has also been studied. Herein, we review the literature on the use of ItP technology for intradermal delivery of naked mRNA vaccines which is expected to overcome the challenges associated with mRNA vaccination. In addition to the physical mechanism, we discuss novel biological mechanisms of iontophoresis, particularly ItP-mediated opening of the skin barriers and the intracellular uptake pathway, and how the combined mechanisms can allow for effective intradermal delivery of mRNA vaccines.

[PMID: 37464256 PMCID: PMC10361146 DOI: 10.1080/21645515.2023.2231333] [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: 04/06/2023] [Revised: 06/14/2023] [Accepted: 06/27/2023] [Indexed: 07/20/2023] Open
Abstract
Cancer represents a challenging medical problem worldwide. Several exploratory studies have been conducted to overcome these limitations. RNA vaccines play an important role in cancer prevention and treatment. Recent studies have shown that RNA vaccines play an important role in cancer prevention. However, there are currently no relevant bibliometric studies. This study aimed to apply bibliometrics to summarize the knowledge structure and research hotspots regarding the role of RNA vaccines in cancer. Publications related to RNA vaccines in cancer were searched on the web of science core collection (WoSCC) database. VOSviewers, CiteSpace and R package "bibliometrix" were used to conduct this bibliometric analysis. A total of 1399 articles were included, comprising 803 original articles and 596 reviews. The number of studies on RNA vaccines against cancer has been increasing annually. China and the United States were the principal countries of origin of publications. Johannes Gutenberg University Mainz, NCI, and Duke University were the main organizations. Frontiers in Immunology is the leading journal in the field. Hot keywords included tumor antigens, lipid nanoparticles, emerging roles, and dendritic cells. This is the bibliometric study to summarize the research trends and development of RNA vaccines for cancer. This information will provide a reference for researchers studying RNA vaccines against cancer.
