Evaluation of a DoE based approach for comprehensive modelling of the effect of lipid nanoparticle composition on nucleic acid delivery
Biomaterials. 2023 May 15;299:122158. doi: 10.1016/j.biomaterials.2023.122158. Online ahead of print.ABSTRACTTherapeutic nucleic acids (TNAs) comprise an alternative to conventional drugs for cancer therapy. Recently, stable nucleic acid lipid particles (SNALPs) have been explored to deliver TNA efficiently and safely both in vitro and in vivo. Small interfering RNA (siRNA) and messenger RNA (mRNA) based drugs have been suggested for a wide range of pathologies, and their respective lipid nanoparticle (LNP) formulations have been optimised using a Design of Experiments (DoE) approach. However, it is uncertain as to whether...

Core-shell tecto dendrimer-mediated cooperative chemoimmunotherapy of breast cancer
J Control Release. 2023 May 16:S0168-3659(23)00334-6. doi: 10.1016/j.jconrel.2023.05.021. Online ahead of print.ABSTRACTDevelopment of effective nanomedicines to deal with tumor immunogenicity and immunosuppression is vital to improve the immunotherapy efficacy. Herein, we developed a programmed strategy not only to activate the tumoral immune microenvironment through immunogenic cell death (ICD) effect but also to promote the maturation of dendritic cells (DCs) in lymph nodes through two modules of core-shell tecto dendrimer (CSTD)-based nanomedicines. The CSTDs with amplified tumor enhanced permeability and retention eff...

GSE160638 MYC induces immunotherapy and interferon- γ resistance through downregulation of JAK2
Contributors : Ettai Markovits ; Ran Elkon ; Michal J Besser ; Gal MarkelSeries Type : Expression profiling by high throughput sequencingOrganism : Homo sapiensImmunotherapy revolutionized the treatment of advanced melanoma. As the pathways mediating resistance to immunotherapy are largely unknown, we conducted transcriptome profiling of pre-immunotherapy tumor biopsies from melanoma patients that received PD-1 blockade (n=36) or adoptive cell therapy with tumor infiltrating lymphocytes (n=37). We identified two melanoma-intrinsic mutually exclusive gene programs, which are controlled by interferon- γ and MYC, and determi...

MYC induces immunotherapy and interferon- γ resistance through downregulation of JAK2
Cancer Immunol Res. 2023 Apr 19:CIR-22-0184. doi: 10.1158/2326-6066.CIR-22-0184. Online ahead of print.ABSTRACTImmunotherapy has revolutionized the treatment of advanced melanoma. Because the pathways mediating resistance to immunotherapy are largely unknown, we conducted transcriptome profiling of pre-immunotherapy tumor biopsies from melanoma patients that received PD-1 blockade or adoptive cell therapy with tumor-infiltrating lymphocytes. We identified two melanoma-intrinsic, mutually exclusive gene programs, which were controlled by interferon-γ (IFNγ) and MYC, and the association with immunotherapy outcome. MYC-over...

801 Novel nanoparticles mediate efficient siRNA/mRNA co-delivery to melanoma
Checkpoint immunotherapy has revolutionized treatment for patients with advanced or metastatic melanoma; however, many patients ’ tumors either fail to respond or develop secondary resistance. As a result, there is an urgent need for an off-the-shelf local treatment that can improve therapeutic outcomes by increasing immune activation and reducing immunosuppressive factors. We developed a library of novel lipophilic poly(b eta-amino ester) (PBAE)-based biodegradable nanoparticle (NP) formulations with different backbone, sidechain, and endcap monomers and various lipophilic/linear ratios to efficiently co-deliver mRNA an...

IDO2-siRNA carried by Salmonella combined with nifuroxazide attenuates melanoma growth
CONCLUSION: In conclusion, IDO2-siRNA combined with nifuroxazide therapy could serve a significant role in the treatment of melanoma-bearing mice, enhance the tumor immunity and provide an experimental basis for identifying a novel combination method for the treatment of melanoma clinically.PMID:36999419 | DOI:10.2174/1874467217666230329102030

Cationic lipid-assisted nanoparticles for simultaneous delivery of CD47 siRNA and R848 to promote antitumor immune responses
Discussion: To our best knowledge, our study pioneered co-delivery system for hydrophilic siCD47 and hydrophobic R848. It can maximize break tumor immune escape caused by CD47 and simultaneously enhance antigen presentation by activating DCs for effector T cell killing while regulating the tumor microenvironment as expected. Not only does it conform to the reports of previous basic research, but also it can break the bottleneck of their clinical application hopefully. Collectively, our findings could lay the foundation for future therapeutic strategies of TNBC.

Targeting ZDHHC9 potentiates anti-programmed death-ligand 1 immunotherapy of pancreatic cancer by modifying the tumor microenvironment
Biomed Pharmacother. 2023 Mar 22;161:114567. doi: 10.1016/j.biopha.2023.114567. Online ahead of print.ABSTRACTImmune checkpoint blockade (ICB) therapy targeting the programmed death 1/programmed death-ligand 1 (PD-1/PD-L1) axis has achieved considerable success in treating a wide range of cancers. However, most patients with pancreatic cancer remain resistant to ICB. Moreover, there is a lack of optimal biomarkers for the prediction of response to this therapy. Palmitoylation is mediated by a family of 23 S-acyltransferases, termed zinc finger Asp-His-His-Cys-type palmitoyltransferases (ZDHHC), which precisely control vari...

Nanoparticles overcome adaptive immune resistance and enhance immunotherapy via targeting tumor microenvironment in lung cancer
Lung cancer is one of the common malignant cancers worldwide. Immune checkpoint inhibitor (ICI) therapy has improved survival of lung cancer patients. However, ICI therapy leads to adaptive immune resistance and displays resistance to PD-1/PD-L1 blockade in lung cancer, leading to less immune response of lung cancer patients. Tumor microenvironment (TME) is an integral tumor microenvironment, which is involved in immunotherapy resistance. Nanomedicine has been used to enhance the immunotherapy in lung cancer. In this review article, we described the association between TME and immunotherapy in lung cancer. We also highligh...

Sialic acid-targeted cyclodextrin-based nanoparticles deliver CSF-1R siRNA and reprogram tumour-associated macrophages for immunotherapy of prostate cancer
Eur J Pharm Sci. 2023 Mar 21;185:106427. doi: 10.1016/j.ejps.2023.106427. Online ahead of print.ABSTRACTProstate cancer remains a serious condition threatening the health of men. Due to the complicated nature of the tumour microenvironment (TME), conventional treatments face challenges including poor prognosis and tumour resistance, therefore new therapeutic strategies are urgently needed. Small interfering RNA (siRNA), a double-stranded non-coding RNA, regulates specific gene expression through RNA interference. Tumour-associated macrophages (TAMs) are a potential therapeutic target in cancer immunotherapy. Colony stimula...
