Hyaluronic acid modified liposomes for targeted delivery of doxorubicin and paclitaxel to CD44 overexpressing tumor cells with improved dual-drugs synergistic effect

The application of combinational therapy breaks the limitation of monotherapy and achieves better clinical benefit for tumor therapy. Herein, a hyaluronic acid/Pluronic F68-based copolymer-mixed micelle was constructed for targeted delivery of chemotherapeutical agent docetaxel (PHDM) in combination with programmed cell death ligand-1(PD-L1) antibody. When PHDM+anti-PDL1 was injected into the blood system, PHDM could accumulate into tumor sites and target tumor cells via CD44-mediated endocytosis and possess tumor chemotherapy. While anti-PDL1 could target PD-L1 protein expressed on surface of tumor cells to the immune checkpoint blockade characteristic for tumor immunotherapy. This strategy could not only directly kill tumor cells but also improve CD8+ T cell level and facilitate effector cytokines release. In conclusion, the rational-designed PHDM+anti-PDL1 therapy strategy creates a new way for tumor immune-chemotherapy.

Work Done

Cancer is one of the reason for mortality and its individual and collective impact is substantial. Conventional chemotherapy utilizes drugs that can destroy Tumor cells effectively. But these agents destroy healthy cells along with the tumor cells, leading to many adverse effects which include hypersensitivity reactions, nephrotoxicity, and neurotoxicity. To minimize the adverse effects, various drug delivery systems (DDSs) has been developed. Among them, nanoparticles are attractive platforms for it. So this review paper explores the recent work done on targeted delivery, enhancing tumor accumulation and longer blood circulation using more effective biomaterial that will enhance the properties of nanoparticles. Moreover, various target-specific delivery of drugs like antibody-targeted, targeting delivery through angiogenesis, mitochondria, CD44 receptor are also explained.

Metastatic Sites

AbstractThe glycocalyx on tumor cells has been recently identified as an important driver for cancer progression, possibly providing critical opportunities for treatment. Metastasis, in particular, is often the limiting step in the survival to cancer, yet our understanding of how tumor cells escape the vascular system to initiate metastatic sites remains limited. Using an in vitro model of the human microvasculature, we assess here the importance of the tumor and vascular glycocalyces during tumor cell extravasation. Through selective manipulation of individual components of the glycocalyx, we reveal a mechanism whereby tumor cells prepare an adhesive vascular niche by depositing components of the glycocalyx along the endothelium. Accumulated hyaluronic acid shed by tumor cells subsequently mediates adhesion to the endothelium via the glycoprotein CD44. Trans-endothelial migration and invasion into the stroma occurs through binding of the isoform CD44v to components of the sub-endothelial extra-cellular matrix. Targeting of the hyaluronic acid-CD44 glycocalyx complex results in significant reduction in the extravasation of tumor cells. These studies provide evidence of tumor cells repurposing the glycocalyx to promote adhesive interactions leading to cancer progression. Such glycocalyx-mediated mechanisms may be therapeutically targeted to hinder metastasis and improve patient survival.

Effects Of Radiation

Melatonin is a hormone with different functions, antitumor actions being one of the most studied. Among its antitumor mechanisms is its ability to inhibit angiogenesis. Melatonin shows antiangiogenic effects in several types of tumors. Combination of melatonin and chemotherapeutic agents have a synergistic effect inhibiting angiogenesis. One of the undesirable effects of chemotherapy is the induction of pro-angiogenic factors, whilst the addition of melatonin is able to overcome these undesirable effects. This protective effect of the pineal hormone against angiogenesis might be one of the mechanisms underlying its anticancer effect, explaining, at least in part, why melatonin administration increases the sensitivity of tumors to the inhibitory effects exerted by ordinary chemotherapeutic agents. Melatonin has the ability to turn cancer totally resistant to chemotherapeutic agents into a more sensitive chemotherapy state. Definitely, melatonin regulates the expression and/or activity of many factors involved in angiogenesis which levels are affected (either positively or negatively) by chemotherapeutic agents. In addition, the pineal hormone has been proposed as a radiosensitizer, increasing the oncostatic effects of radiation on tumor cells. This review serves as a synopsis of the interaction between melatonin and angiogenesis, and we will outline some antiangiogenic mechanisms through which melatonin sensitizes cancer cells to treatments, such as radiotherapy or chemotherapy.

Toxic Reactions

Methotrexate (MTX) is an anchor drug for the treatment of rheumatoid arthritis (RA); however, long-term and high-dose usage of MTX for patients can cause many side effects and toxic reactions. To address these difficulties, selectively delivering MTX to the inflammatory site of a joint is promising in the treatment of RA. In this study, we prepared MTX-PEI@HA nanoparticles (NPs), composed of hyaluronic acid (HA) as the hydrophilic negative electrical shell, and MTX-linked branched polyethyleneimine (MTX-PEI) NPs as the core. MTX-PEI@HA NPs were prepared in the water phase by a one-pot method. The polymeric NPs were selectively internalized via CD44 receptor-mediated endocytosis in the activated macrophages. In the in vivo mice mode study, treatment with MTX-PEI@HA NPs mitigated inflammatory arthritis with notable safety at a high dose of MTX. We highlight the distinct advantages of aqueous-synthesized NPs coated with HA for arthritis-selective targeted delivery, thus verifying MTX-PEI@HA NPs as a promising MTX-based nanoplatform for treatment of RA.
