Full eradication of pre-clinical human papilloma virus-induced tumors by a lentiviral vaccine
EMBO Mol Med. 2023 Sep 7:e17723. doi: 10.15252/emmm.202317723. Online ahead of print.ABSTRACTHuman papillomavirus (HPV) infections are the cause of all cervical and numerous oropharyngeal and anogenital cancers. The currently available HPV vaccines, which induce neutralizing antibodies, have no therapeutic effect on established tumors. Here, we developed an immuno-oncotherapy against HPV-induced tumors based on a non-integrative lentiviral vector encoding detoxified forms of the Early E6 and E7 oncoproteins of HPV16 and 18 genotypes, namely, "Lenti-HPV-07". A single intramuscular injection of Lenti-HPV-07 into mice bearing...

Leptin/lipopolysaccharide-treated dendritic cell vaccine improved cellular immune responses in an animal model of breast cancer
CONCLUSION: Compared to the Leptin-treated mDC and LPS-treated mDC vaccines, the Leptin/LPS-treated mDC vaccine was more effective in inhibiting BC development and boosting immune responses against tumor.PMID:37647347 | DOI:10.1080/08923973.2023.2253989

Plant Viruses as Adjuvants for Next-Generation Vaccines and Immunotherapy
Vaccines (Basel). 2023 Aug 16;11(8):1372. doi: 10.3390/vaccines11081372.ABSTRACTVaccines are the cornerstone of infectious disease control and prevention. The outbreak of SARS-CoV-2 has confirmed the urgent need for a new approach to the design of novel vaccines. Plant viruses and their derivatives are being used increasingly for the development of new medical and biotechnological applications, and this is reflected in a number of preclinical and clinical studies. Plant viruses have a unique combination of features (biosafety, low reactogenicity, inexpensiveness and ease of production, etc.), which determine their potentia...

Does Amyloid-β Aggregation Cause Broad Disruption of Proteostasis?
https://www.fightaging.org/archives/2023/08/does-amyloid-%ce%b2-aggregation-cause-broad-disruption-of-proteostasis/
Researchers here speculate on the ability of insoluble amyloid-β aggregates to be broadly disruptive of the solubility of many other proteins, and thus disruptive to cell and tissue function. Is this important in aging? The evidence here shows the existence of the mechanism in a lower species, but that doesn't n...

Viral nanoparticles: Current advances in design and development
Biochimie. 2023 Aug 10:S0300-9084(23)00197-9. doi: 10.1016/j.biochi.2023.08.006. Online ahead of print.ABSTRACTViral nanoparticles (VNPs) are self-assembling, adaptable delivery systems for vaccines and other therapeutic agents used in a variety of biomedical applications. The potential of viruses to invade and infect various hosts and cells renders them suitable as potential nanocarriers, possessing distinct functional characteristics, immunogenic properties, and improved biocompatibility and biodegradability. VPNs are frequently produced through precise genetic or chemical engineering, which involves adding diverse seque...

Alphaviruses in cancer immunotherapy
Int Rev Cell Mol Biol. 2023;379:143-168. doi: 10.1016/bs.ircmb.2023.03.011. Epub 2023 Jun 14.ABSTRACTAlphaviruses have frequently been engineered for cancer therapy, cancer immunotherapy, and cancer vaccine development. As members of self-replicating RNA viruses, alphaviruses provide high levels of transgene expression through efficient self-amplifying of their RNA genome in host cells. Alphavirus vectors can be used as recombinant viral particles or oncolytic viruses. Alternatively, either naked or nanoparticle-encapsulated RNA and DNA replicons can be utilized. In the context of cancer prevention and treatment, antitumor...

Viral vectors engineered for gene therapy
Int Rev Cell Mol Biol. 2023;379:1-41. doi: 10.1016/bs.ircmb.2023.05.005. Epub 2023 Jul 1.ABSTRACTGene therapy has seen major progress in recent years. Viral vectors have made a significant contribution through efficient engineering for improved delivery and safety. A large variety of indications such as cancer, cardiovascular, metabolic, hematological, neurological, muscular, ophthalmological, infectious diseases, and immunodeficiency have been targeted. Viral vectors based on adenoviruses, adeno-associated viruses, herpes simplex viruses, retroviruses including lentiviruses, alphaviruses, flaviviruses, measles viruses, rh...
