We previously reported that inactivated Sendai virus particle (hemagglutinating virus of Japan envelope; HVJ‐E) has anti‐tumor effects by eliciting IL‐6 production in dendritic cells (DCs). In the present study, we investigated which components of HVJ‐E elicit IL‐6 production. HVJ‐E containing F0 protein inactive for virus envelope–cell membrane fusion enhanced IL‐6 production. Reconstituted liposomes containing F protein stimulated IL‐6 production. The antibody against F protein inhibited IL‐6… 
Cancer immunotherapy using the Fusion gene of Sendai virus
TLDR
It is found that F plasmid treatment resulted in a significant increase in the secretion of the chemokine RANTES by tumour-infiltrating T cells, which means F gene therapy may show promise as a novel therapeutic for single or combined cancer immunotherapy.
Systemic Administration of a Novel Immune-Stimulatory Pseudovirion Suppresses Lung Metastatic Melanoma by Regionally Enhancing IFN-γ Production
TLDR
IL-12–conjugated HVJ-E is a promising tool for the treatment of cancers, including lung metastasis by inducing local production of IFN-γ in the lungs and generating large numbers of melanoma-specific CTLs.
A New Approach to Castration-Resistant Prostate Cancer Using Inactivated Virus
TLDR
HVJ-E therapy could be an innovative immune therapy for prostate cancer with an acceptable safety profile and treatment for CRPC patients was feasible, and the PSA levels of a subgroup of patients responded.
Hemagglutinating virus of Japan envelope (HVJ-E) can enhance the immune responses of swine immunized with killed PRRSV vaccine.
TLDR
The results suggest that HVJ-E could be employed as an effective adjuvant to enhance the humoral and cellular responses of piglets to PRRSV.

TLDR
It is reported that inactivated, replication-defective Sendai virus particles (HVJ-E) also has an antitumor effect through non-T cell immunity, and injection caused systemic activation of NK cells and enhanced their cytotoxity against tumor cells.
TLR-Independent Induction of Dendritic Cell Maturation and Adaptive Immunity by Negative-Strand RNA Viruses1
TLDR
The data presented here provide evidence for the existence of a novel intracellular pathway independent of TLR-mediated signaling responsible for live virus triggering of DC maturation and demonstrate its critical role in the onset of antiviral immunity.
Type I interferon induction pathway, but not released interferon, participates in the maturation of dendritic cells induced by negative-strand RNA viruses.
TLDR
A strong correlation between DC maturation and the ability of the virus to induce type I IFN synthesis was demonstrated, and separate pathways for the induction of cytokine secretion and the up-regulation of major histocompatibility complex and costimulatory molecules were activated.
Sendai virus internal fusion peptide: structural and functional characterization and a plausible mode of viral entry inhibition.
TLDR
It is found that SV-201 and its elongated form, SV-197, are highly potent in inducing fusion of the highly stable large unilamellar vesicles composed of egg phosphatidylcholine, a property found only in an extended version of the HIV-1 fusion peptide.
Glycoproteins of Sendai virus (HVJ) have a critical ratio for fusion between virus envelopes and cell membranes.
TLDR
It was found that for maximum cytotoxic activity of the vesicles, there was an optimal ratio of F to HN of two, which suggests that HN is not merely the initial binding site to the cell surface, and that interactions between HN and F proteins on the virus surface may be important for the biological activities of these proteins onThe cells.
Reconstituted fusion liposomes for gene transfer in vitro and in vivo
TLDR
HVJ-liposomes that are efficient in vitro and in vivo gene delivery vehicles based on cell fusion properties of the Sendai virus are developed, although replication of the viral genome is severely impaired by prior UV-irradiation of HVJ particles.
