Abstract
Mucosal vaccines are receiving increasing interest both for protecting against infectious diseases and for inducing therapeutic immune responses to treat non-infectious diseases. However, the mucosal barriers of the lungs, gastrointestinal tract, genitourinary tract, nasal, and oral tissues each present unique challenges for constructing efficacious vaccines. Vaccination through each of these mucosae requires transport through the mucus and across specialized epithelia to reach tissue-specific immune cells and lymphoid structures, necessitating finely tuned and multifunctional strategies. Serving as inspiration for mucosal vaccine design, pathogens have evolved elaborate, diverse, and multipronged approaches to penetrate and infect mucosae. This review is focused on biomaterials-based strategies, many inspired by pathogens, for designing mucosal vaccine platforms. Passive and active technologies are discussed, along with the microbial processes that they seek to mimic.

[PMID: 35858677 PMCID: PMC9350170 DOI: 10.1111/jam.15720] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/01/2022] [Revised: 05/30/2022] [Accepted: 07/14/2022] [Indexed: 11/28/2022]
Abstract
Aims This study aimed to provide a safe, stable and efficient SARS‐CoV‐2 oral vaccine development strategy based on the type III secretion system of attenuated Salmonella and a reference for the development of a SARS‐CoV‐2 vaccine. Methods and Results The attenuated Salmonella mutant ΔhtrA‐VNP was used as a vector to secrete the antigen SARS‐CoV‐2 based on the type III secretion system (T3SS). The Salmonella pathogenicity island 2 (SPI‐2)‐encoded T3SS promoter (sifB) was screened to express heterologous antigens (RBD, NTD, S2), and the SPI‐2‐encoded secretion system (sseJ) was employed to secrete this molecule (psifB‐sseJ‐antigen, abbreviated BJ‐antigen). Both immunoblotting and fluorescence microscopy revealed effective expression and secretion of the antigen into the cytosol of macrophages in vitro. The mixture of the three strains (BJ‐RBD/NTD/S2, named AisVax) elicited a marked increase in the induction of IgA or IgG S‐protein Abs after oral gavage, intraperitoneal and subcutaneous administration. Flow cytometric analysis proved that AisVax caused T‐cell activation, as shown by a significant increase in CD44 and CD69 expression. Significant production of IgA or IgG N‐protein Abs was also detected by using psifB‐sseJ‐N(FL), indicating the universality of this strategy. Conclusions Delivery of multiple SARS‐CoV‐2 antigens using the type III secretion system of attenuated Salmonella ΔhtrA‐VNP is a potential COVID‐19 vaccine strategy. Significance and Impact of the Study The attenuated Salmonella strain ΔhtrA‐VNP showed excellent performance as a vaccine vector. The Salmonella SPI‐2‐encoded T3SS showed highly efficient delivery of SARS‐COV‐2 antigens. Anti‐loss elements integrated into the plasmid stabilized the phenotype of the vaccine strain. Mixed administration of antigen‐expressing strains improved antibody induction.

Abstract
Thousands of breakthrough infections are confirmed after intramuscular (i.m.) injection of the approved vaccines against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). Two major factors might contribute to breakthrough infections. One is the emergence of mutant variants of SARS-CoV-2, and the other is that i.m. injection has an inefficient ability to activate mucosal immunity in the upper respiratory tract. Here, we devised a dual-chambered nanocarrier that can codeliver the adjuvant CBLB502 with prefusion-spike (pre-S) onto a ferritin nanoparticle. This vaccine enabled enhanced systemic and local mucosal immunity in the upper and lower respiratory tract. Further, codelivery of CBLB502 with pre-S induced a Th1/Th2-balanced immunoglobulin G response. Moreover, the codelivery nanoparticle showed a Th1-biased cellular immune response as the release of splenic INF-γ was significantly heightened while the level of IL-4 was elevated to a moderate extent. In general, the developed dual-chambered nanoparticle can trigger multifaceted immune responses and shows great potential for mucosal vaccine development.

Abstract
In the last decades, many nanovectors were developed for different diagnostic or therapeutic purposes. However, most nanosystems have been designed using a “bottom-up” approach, in which the basic components of the nanovector become assembled to achieve complex and specific behaviors. Despite the fine control of formulative conditions, the complexity of these systems often results cumbersome and difficult to scale-up. Recently, biomimetic materials emerged as a complementary or alternative design approach through a “top-down strategy”, using cell-derived materials as building blocks to formulate innovative nanovectors. The use of cell membranes as nanoparticle coatings endows nanomaterials with the biological identity and some of the functions of the cells they are derived from. In this review, we discuss some of the latest examples of membrane coated and membrane-derived biomimetic nanomaterials and underline the common general functions offered by the biomaterials used. From these examples, we suggest a systematic classification of these biomimetic materials based on their biological sources and formulation techniques, with their respective advantages and disadvantages, and summarize the current technologies used for membranes isolation and integration on nanovectors. We also discuss some current technical limitations and hint to future direction of the improvement for biomimetics.
