In summary, protamine was the only peptide carrier evaluated in clinical trials of mRNA vaccines. Several special characteristics make DCs suitable vaccination targets, including their T-cell-oriented migration in the lymph nodes and high expression of major histocompatibility complex (MHC) molecules, co-stimulators, and cytokines (Garg et al. PLOS Negl Tropical Dis 10:e0004746, Sebastian M, Papachristofilou A, Weiss C et al (2014) Phase Ib study evaluating a self-adjuvanted mRNA cancer vaccine [RNActive(R)] combined with local radiation as consolidation and maintenance treatment for patients with stage IV non-small cell lung cancer. In the vaccination process, mRNA formulation and delivery strategies facilitate effective expression and presentation of antigens, and immune stimulation. Intravaginal injection is another approach to deliver mRNA vaccines to the site of infection to express neutralizing antibodies. 2005) and PKR (Anderson et al. Over 10 million scientific documents at your fingertips. 2019) and low anti-tumor activity against several types of cancer (Rausch et al. PAMAM dendrimer is another cationic polymer material.

Both buffers contain calcium which was suggested to trigger the uptake of mRNA into human cells via a calcium-dependent route (Probst et al. Muscles contain a large network of blood vessels that can help recruit and recirculate different types of immune cells, such as the infiltrating APCs, to the injection site (Liang et al. (2018). 2015). The total amount of protein produced via IV administration is often the highest compared to other routes (Pardi et al. 2019).

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. It is a vicinal diketone (two C=O groups, side-by-side) with the molecular formula C 4 H 6 O 2.Diacetyl occurs naturally in alcoholic beverages and is added to some foods to impart its buttery flavor. A recent study indicated that after IM injection of LNPs-encapsulated mRNA, the radiolabeled mRNA was detected at the site of injection and draining lymph node for at least 28 h (Lindsay et al. Cancer Immunol Res 7:B209, Sabnis S, Kumarasinghe ES, Salerno T et al (2018) A novel amino lipid series for mRNA delivery: improved endosomal escape and sustained pharmacology and safety in non-human primates. Expert Rev Vaccines 16:871–881, Ibrahim MM (2010) Subcutaneous and visceral adipose tissue: structural and functional differences. 2017). Therefore, IV injection is often used to deliver mRNAs encoding antibodies when the high functional concentration of neutralizing antibodies is required in the bloodstream (Kose et al. The three mRNAs were used in an equal mass ratio in mouse tumor models (Van Lint et al. Similar to functional lipid-based carriers, polymers can also protect RNA from RNase-mediated degradation and facilitate intracellular delivery (Kowalski et al. Additionally, the lymph vessels may directly transport small-sized lipid nanoparticles to draining lymph nodes (Moyer et al.

Compared to other preparation methods, the use of continuous-flow microfluidic devices increases reproducibility, improves molecular stability, reduces the chance of contamination, and is easily scaled up for preclinical and clinical studies (Damiati et al. 2013). For further stimulation and maturation, the DCs were transfected with mRNAs encoding specific antigens and maturation signals (Benteyn et al. Biomacromolecules, Boczkowski D, Nair SK, Snyder D et al (1996) Dendritic cells pulsed with RNA are potent antigen-presenting cells in vitro and in vivo. It gives beginner English learners easy access to the vocabulary, grammar and functions of English as it is actually used in a comprehensive range of social situations. 2017), intranodal (Kreiter 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.

Afluria ® Tetra (Seqirus) is a split virus quadrivalent inactivated influenza vaccine that was authorized for use in Canada in adults and children 5 years of age and older on February 22, 2018. Because of these properties, ID injection was tested in clinical studies for delivering mRNA vaccine encoding rabies virus glycoprotein (Alberer et al. Oncotarget 5, Joe PT, Christopoulou I, van Hoecke L et al (2019) Intranodal administration of mRNA encoding nucleoprotein provides cross-strain immunity against influenza in mice. Researchers have investigated many methods to deliver mRNA vaccines. Moreover, a recent study reported that a cationic copolymer material co-delivering one mRNA encoding OVA and a CpG ssDNA adjuvant eliminated OVA-expressing lymphoma tumor from mice after either SC or IV administration (Haabeth et al. Nature 274:923–924, Dong Y, Dorkin JR, Wang W et al (2016) Poly(glycoamidoamine) brushes formulated nanomaterials for systemic siRNA and mRNA delivery in vivo. When delivering mRNA vaccines, a comparison of several administration routes will help determine the most appropriate injection method and promote efficacy. One feature is the ease to store and prepare. (2001), Moyer et al.

For example, delivery carriers, such as lipid-derived and polymer-derived materials, dramatically increased cellular uptake of RNAs, thus receiving tremendous attention in recent years (Reichmuth et al. World Allergy Organ J 8:9, Seubert A, Calabro S, Santini L et al (2011) Adjuvanticity of the oil-in-water emulsion MF59 is independent of Nlrp3 inflammasome but requires the adaptor protein MyD88. Effective immunization observed in preclinical animal studies may or may not be applied to human. The LNPs usually contain one or more of the functional lipid components that are crucial for the intracellular RNA delivery described above (Midoux and Pichon 2015; Kowalski et al. 2016; Guardo et al. Ann Oncol 24:2686–93, Wolff JA, Malone RW, Williams P et al (1990) Direct gene transfer into mouse muscle in vivo. 2016) were developed. Cancer Immunol Immunother 65:1075–1083, Semple SC, Akinc A, Chen J et al (2010) Rational design of cationic lipids for siRNA delivery. 2019). 2018). The cationic or ionizable lipid materials, such as 1,2-di-O-octadecenyl-3-trimethylammonium propane (DOTMA), N,N-Dimethyl-2,3-bis[(9Z,12Z)-octadeca-9,12-dienyloxy]propan-1-amine (DLinDMA), and N1,N3,N5-tris(3-(didodecylamino)propyl)benzene-1,3,5-tricarboxamide (TT3) usually contain one or multiple amino groups (Semple et al.
