The vascular and lymphatic vessels in this layer of skin also help transport mRNA vaccines and APCs to the draining lymph nodes to activate T and B cells (Kashem et al. Next, the mRNA-transfected DCs were validated with their phenotypes and functions, then re-introduced back to the patients to function as antigen-specific APCs (Benteyn et al.

In: Clinical procedures for safer patient care. Overall, LNPs-based mRNA vaccines have shown efficacy in preventing infectious diseases and treating cancers in preclinical and early-stage clinical studies (Bahl et al. 2010; Jayaraman et al. J Virol 87:3409–24, Wilgenhof S, Van Nuffel AMT, Benteyn D et al (2013) A phase IB study on intravenous synthetic mRNA electroporated dendritic cell immunotherapy in pretreated advanced melanoma patients.

PLoS ONE 13:e0201464, Belliveau NM, Huft J, Lin PJC et al (2012) Microfluidic synthesis of highly potent limit-size lipid nanoparticles for in vivo delivery of siRNA. These chip-based microfluidic devices mix two laminar flows, the RNA-containing aqueous phase and the carriers-containing solvent phase, through a confined microchannel equipped with chaotic mixers at a controlled speed, leading to rapid diffusion, change of polarity and self-assembly of mRNA-LNP at the interface (Belliveau et al. Both buffers contain calcium which was suggested to trigger the uptake of mRNA into human cells via a calcium-dependent route (Probst et al. Furthermore, protamine-CPP fusion protein combines cationic and cell-penetrating features. Intranodal (IN) injection directly introduces mRNA vaccines to the peripheral lymphoid organs where APCs and primed T or B cells interact (Fig 1e). 2017) or sonoporation (Dewitte et al. 2019)], only a few CPPs delivered mRNA vaccines. 2019). The viral particle and self-amplifying mRNA pair can be selected from either the same or different virus species (Dorange et al. J Control Release 156:203–11, Ying H, Zaks TZ, Wang RF et al (1999) Cancer therapy using a self-replicating RNA vaccine. 2017; Fooks et al. This formulation delivered OVA-mRNA and delayed OVA-expressing lymphoma growth in mice after IV injection (Fan et al. Cationic peptides contain many lysine and arginine residues that provide positively charged amino groups, therefore enabling complexing with nucleic acids through electrostatic interactions (Grau et al. For example, a cationic lipid, N-bis(2-hydroxyethyl)-N-methyl-N-(2-cholesteryloxy-carbonyl aminoethyl) ammonium bromide (BHEM-Chol), was mixed with a block copolymer poly(ethylene glycol)-block-poly(lactic-co-glycolic acid) (PEG-b-PLGA) and PLGA to form a lipid–polymer hybrid emulsion for mRNA delivery (Fan et al. 2012; Billingsley et al. Sci Rep 6:22509, Billingsley MM, Singh N, Ravikumar P et al (2020) Ionizable lipid nanoparticle-mediated mRNA delivery for human CAR T cell engineering. This epitope competition was alleviated by sequential injection of pp65-encoding mRNA on day 1 and all seven antigen-coding mRNAs on day 21 (John et al. Indian J Pharm Sci 80:781–789, Haabeth OAW, Blake TR, McKinlay CJ et al (2018) mRNA vaccination with charge-altering releasable transporters elicits human T cell responses and cures established tumors in mice. 2010). This four-level American English reading course uses carefully selected reading texts to help students read effectively. 2017). Despite the advantages of IV injection mentioned above, the plasma proteins, enzymes, and mechanical forces in the bloodstream may hinder the vaccine delivery (Reichmuth et al. 2019; Sebastian et al. Science (New York, N.Y.) 349:739, McCarthy HO, McCaffrey J, McCrudden CM et al (2014) Development and characterization of self-assembling nanoparticles using a bio-inspired amphipathic peptide for gene delivery. 2016; Van Lint et al. 2012). In particular, numerous mRNA vaccines are being developed to tackle infectious diseases and various types of cancer, with many advancing to different stages of clinical trials (Pardi et al. 1993). Hepatitis C is the most commonly reported bloodborne infection in the United States (1), and surveys conducted during 2013–2016 indicated an estimated 2.4 million persons (1.0%) in the nation were living with hepatitis C (2).Percutaneous exposure is the most efficient mode of hepatitis C virus (HCV) transmission, and injection drug use (IDU) is the … To broaden immunity with a multivalent mRNA vaccine, three self-amplifying mRNAs encoding hemagglutinin (HA) from three different influenza virus strains were formulated by a medium-length PEI in equal mass, co-delivered to mice intramuscularly, and protected mice against viral challenge (Vogel et al.

In the presence of a storage reagent, such as 10% trehalose, freeze-dried naked RNA remains stable in the refrigerator temperature (4 ℃) for up to 10 months (Jones et al. Such injection enhanced immune cell recruitment to the muscle injection site, expanded the antigen-specific CD8+ T-cell counts and resulted in better survival upon the influenza challenge than other groups receiving a single antigen-encoding self-amplifying mRNA (Manara et al. A variety of responses were observed in all patients, ranging from epitope-induced T-cell response, reduced metastasis to progression-free survival (Sahin et al.

Among the mucosal administration routes, intranasal and intravaginal administrations were utilized to deliver mRNA vaccines (Lorenzi et al. Naked mRNA vaccines are more susceptible to the delivery obstacles, namely, RNase degradation and intracellular delivery (Singer and Linderman 1990; Canton 2018). J Clin Investig 11:327–335, Harvey TJ, Liu WJ, Wang XJ et al (2004) Tetracycline-inducible packaging cell line for production of flavivirus replicon particles. Local injections, such as IM, ID, SC, and IN administrations, deliver LNPs mRNA vaccine to resident/infiltrating APCs and related immune cells, stimulating strong and prolonged local expression (Kreiter et al. Lipid and lipid-derived nanoparticles (LNPs) were previously used to deliver small molecule drugs and siRNAs (Brito et al. 2020). 2016). mRNA vaccines have been delivered in various formats: encapsulation by delivery carriers, such as lipid nanoparticles, polymers, peptides, free mRNA in solution, and ex vivo through dendritic cells. The delivery formats and delivery materials described above have advanced to various stages of preclinical and clinical studies.

The dose of the antigen-encoding mRNA was equal or several-fold larger than each of the three mRNAs encoding immunostimulatory proteins (Van Lint et al. 2016). 2020). In the presence of protamine, antigen-encoding mRNA was more resistant to RNase degradation, suggesting better stability in vitro (Hoerr et al. 2016). 2013). On one side, the immunogenicity might benefit vaccination by providing some adjuvant activity. Moreover, IV injections may also allow the direct access of mRNA vaccines to immune cells and lymphoid organs in the circulatory system, which may enhance the vaccination efficacy (Kranz et al. In this section, we summarize the recent results for the co-delivery of mRNA vaccines, including delivery formats, dose ratios, formulation methods, and injection routes of the components.

The resulting nanoparticle induced innate and specific immune responses in primary human DC upon in vitro delivery. Several features of in vitro transcribed mRNA contribute to its vaccine potential. It was the first classified as a high-severity season for all age groups, with high levels of outpatient clinic and emergency department visits for influenza-like illness, high rates of influenza-related hospitalization, and high mortality.

However, after co-formulating this mRNA with six additional antigen-encoding mRNAs in equal mass by LNP and simultaneous intramuscular injection, the anti-pp65 response was barely above the negative control. 2019). The use of new formulation technologies, such as continuous-flow microfluidic devices, enabled reproducible production of nanoparticles at various scales with controllable sizes (Jahn et al. If such interference is detected, modification of vaccination procedure, such as injection time, is likely needed to improve immune response. 2015; Batich et al. In this chapter, we summarize the routes of administrations for mRNA vaccines, discuss mRNA delivery carriers and their corresponding formulation methods, and overview the challenges and future development of mRNA vaccines. Hence, protection against RNases is critical for most in vivo delivery strategies. However, the formulation of polymer-based mRNA nanoparticles tends to have high polydispersity (Kowalski et al. 2017).

Human Gene Ther 10:2719–24, Zhuang X, Qi Y, Wang M et al (2020) mRNA vaccines encoding the HA protein of influenza A H1N1 virus delivered by cationic lipid nanoparticles induce protective immune responses in mice. Fourth, transportation and storage of mRNA may be easier than protein-based vaccines, since RNA, if protected properly against ribonucleases (RNases), is less prone to degradation compared to proteins (Stitz et al. 2018; Kose et al. A short CPP called Xentry (sequence: N-LCLRPVG-C) was fused to truncated protamine (sequence: N-RSQSRSRYYRQRQRSRRRRRRS-C) and delivered a protein-coding mRNA into several human cell lines in vitro (Bell et al. Interestingly, the delivery approach appeared to influence the vaccine efficacy of this co-delivery method. IN injection is considered to be an efficient way of vaccination, since the APCs in lymphoid organs can readily engulf the injected mRNA vaccine (Kreiter et al.
