Abstract
Adenovirus (Ad) has been extensively developed as a gene delivery vector, but the potential side effect caused by systematic immunization remains one major obstacle for its clinical application. Needle-free mucosal immunization with Ad-based vaccine shows advantages but still faces poor mucosal responses. We herein report that the chemical engineering of single live viral-based vaccine effectively modulated the location and pattern of the subsequently elicited immunity. Through precisely assembly of functional materials onto single live Ad particle, the modified virus entered host cell in a phagocytosis-dependent manner, which is completely distinct from the receptor-mediated entry of native Ad. RNA-Seq data further demonstrated that the modified Ad-induced innate immunity was sharply reshaped via phagocytosis-related pathway, therefore promoting the activation and mature of antigen presentation cells (APC). Moreover, the functional shell enabled the modified Ad-based vector with enhanced muco-adhesion to nasal tissues in mice, and then prolonged resident time onto mucosal surface, leading to the robust mucosal IgA production and T cell immunity at local and even remote mucosal-associated lymphoid tissues. This study demonstrated that vaccine-induced immunity can be well modulated by chemistry engineering, and this method provides the rational design for needle-free mucosa-targeting vaccine against a variety of emerging infectious diseases.

Lin CH, Chang YC, Chang TK, Huang CH, Lu YC, Huang CH, Chen MJ. Enhanced expression of coxsackievirus and adenovirus receptor in lipopolysaccharide-induced inflammatory macrophages is through TRIF-dependent innate immunity pathway. Life Sci 2020; 265:118832. [PMID: 33259866 DOI: 10.1016/j.lfs.2020.118832] [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: 07/09/2020] [Revised: 11/17/2020] [Accepted: 11/23/2020] [Indexed: 10/22/2022]
Abstract
AIMS Inflammatory macrophages have been proposed as a therapeutic target for joint disorders caused by inflammation. This study aimed to investigate the expression and regulation of coxsackievirus-adenovirus receptor (CAR) in lipopolysaccharide (LPS)-stimulated inflammatory macrophages whereby to evaluate the feasibility of virus-directed enzyme prodrug therapy (VDEPT). MAIN METHODS Macrophage cell lines (RAW264.7 and J774A.1) and primary macrophage cells derived from rat spleen were used to evaluate the expression of CAR protein or CAR mRNA. Specific inhibitors for TLR4 pathway were used to investigate the regulation of CAR expression. CAR expression in rat joints was documented by immunohistochemistry. Conditionally replicating adenovirus, CRAd-EGFP(PS1217L) or CRAd-NTR(PS1217H6), and non-replicating adenovirus CTL102 were used to transduce genes for enhanced green fluorescent protein (EGFP) or nitroreductase (NTR), respectively. The expression of EGFP, NTR, and the toxicity induced by CB1954 activation were evaluated. KEY FINDINGS The in vitro experiments revealed that CAR upregulation was mediated through the TLR4/TRIF/IRF3 pathway in LPS-stimulated inflammatory macrophage RAW264.7 and J774A.1 cells. The inflammatory RAW264.7 cells upregulated CAR expression following LPS stimulation, leading to higher infectability, increased NTR expression, and enhanced sensitization to CB1954. In animal experiments, the induction of CAR expression was observed in the CD68-expressing primary macrophages and in the CD68-expressing macrophages within joints following LPS stimulation. SIGNIFICANCE In conclusion, we report an enhanced CAR expression in inflammatory macrophages in vitro and in vivo through the immune response elicited by LPS. Thus, the TLR4/TRIF/IRF3 pathway of macrophages, when activated, could facilitate the therapeutic application of adenovirus-mediated VDEPT.

Abstract
Monocytes provide initial surveillance for pathogenic glycopeptides via scavenger receptors (SRs) and for viruses via Toll-like receptors (TLRs) which trigger pro-inflammatory response. However, specific interactions between SR-A1 and TLRs have not yet been assessed in human cytomegalovirus (HCMV)-exposed monocytes. Our results showed two patterns of gene expression upon HCMV exposure: genes that were induced within 10 min include SR-A1, Lyn, TLR-2, and IL-12p35, whereas those induced at 1h are TLR-3, TLR-9, TRIF, IRF-3, and IFN-beta. NF-kappaB p65 and TNF-alpha were elevated at both 10 min and 1h post exposure. Further, inhibitory studies using neutralizing antibodies and morpholino antisense oligonucleotides suggested that within 10 min of HCMV exposure, transcription of TNF-alpha and IL-12 genes is TLR-2-dependent fashion. However, induction of both TLR-3-mediated IFN-beta and TLR-9-mediated TNF-alpha at 1h was dependent on SR-A1. These findings reveal a novel mechanistic insight into an interrelationship between SR-A1 and TLR-3/-9 signaling in HCMV-exposed monocytes.

Tat conjugation of adenovirus vector broadens tropism and enhances transduction efficiency. Life Sci 2008; 83:747-55.

Abstract
AIMS Adenovirus vectors (Advs) have been very useful for basic research and clinical gene therapy because they propagate to high titers and efficiently transduce cells and tissues regardless of the mitotic status. However, poor transduction of cells that lack the coxsackievirus and adenovirus receptor (CAR), the primary receptor for Advs, has limited Adv application. In this study, we attempted to generate novel Tat-Advs (Advs conjugated with the HIV Tat-derived peptide, a protein-transduction domain (PTD)) to broaden Adv tropism and enhance transduction efficiency. MAIN METHODS We constructed Tat-Advs by chemically conjugating Tat peptide to the surface-exposed lysine residues on Advs. We compared the gene transfer activity of Tat-Advs with that of unmodified Advs by measuring the luciferase expression in several types of cell lines. KEY FINDINGS Tat-Advs showed gene expression 1 to 3 log orders higher than unmodified Advs in CAR-negative adherent cells and blood cells, which are refractory to conventional Advs. The inhibition of Tat-Adv-mediated gene expression by heparin and macropinocytosis inhibitor confirms that binding of Tat-Adv to cellular HSPGs and macropinocytosis are essential for efficient CAR-independent transduction. We also demonstrated that Adv modified with another PTD (R8) had the same high transduction efficiency as Tat-Adv. SIGNIFICANCE These data suggest that Tat-Advs are important tools for transducing cells and will be useful as platform vectors for gene therapy.
