  • Publication number: 20230285559
    Abstract: A therapeutic hydrogel material is disclosed for the delivery of CAR-T cells that allows their distribution in the tumor resection recess, cavity, or void in combination with platelets decorated with the anti-programmed death-ligand 1 (PDL1) blocking antibody (aPDL1). The delivered hydrogel material acts as a reservoir for both CAR-T cells and platelet-bound aPDL1. Furthermore, inflammation occurring during the surgical wound healing triggers the release of platelet-derived microparticles containing the aPDL1. Cells delivered by the engineered hydrogel show significant control of local and distant tumor recurrence without causing toxic effects. In some embodiments, nanoparticles containing cytokines are also loaded in the therapeutic hydrogel material to maintain the activity and proliferation ability of CAR-T cells.

  • Publication number: 20230240981
    Abstract: A therapeutic hybrid microneedle patch mimics the inherent counter-regulatory effects of ?-cells and ?-cells for blood glucose management by dynamically releasing insulin or glucagon contained within the microneedles of the therapeutic hybrid microneedle patch. The two types of microneedles in the therapeutic hybrid microneedle patch share a co-polymerized matrix but comprise different ratios of the key monomers to be ‘dually-responsive’ to both hyper- and hypoglycemic glucose conditions. In a type 1 diabetic mouse model, the therapeutic hybrid microneedle patch effectively controls hyperglycemia while minimizing the occurrence of hypoglycemia in the setting of insulin therapy and simulated delayed meal or insulin overdose. In other embodiments, multiple patches are applied to achieve similar results.

  • Publication number: 20230218507
    Abstract: Chimeric antigen receptor T cells (CAR T) therapy reached a milestone in eradicating B-cell malignancies, but beneficial effects in solid tumors are not obtained yet. A porous microneedle patch is disclosed that carries CAR T cells to solid tumors (or other cell types). The device is a honeycomb-like porous microneedle patch that accommodates CAR T cells and allows in situ penetration-media seeding of CAR T cells within post-surgical resection of solid tumors. CAR T cells loaded in the pores of the microneedle tips were readily escorted to the tumor in an evenly scattered manner without losing their activity. Such microneedle-mediated local delivery enhanced infiltration and immune stimulation of CAR T cells as compared to direct intratumoral injection. This tailorable patch offers a transformative platform for scattered seeding of living cells for treating a variety of diseases. Other cell types may be loaded into the porous microneedles.

  • Publication number: 20230201128
    Abstract: The method of treating obesity-induced glucose intolerance and liver fibrosis includes administering to a patient a therapeutically effective amount of a substance for inhibiting the Notch signaling pathway of the patient. The substance is formed from encapsulated ?-secretase inhibitor (GSI) nanoparticles. As a non-limiting example, each nanoparticle may be formed from a GSI, such as dibenzazepine (a bioavailable GSI) encapsulated in poly(lactic co-glycolic acid) (PLGA). The encapsulated GSI nanoparticles (GSI NPs) provide localized and effective inhibition of hepatic Notch signaling, thus improving obesity-induced glucose tolerance and liver fibrosis without intestinal side effects.

  • Publication number: 20230010556
    Abstract: A cold atmospheric plasma (CAP)-mediated ICB therapy/delivery device are disclosed herein that employs a patch having microneedles that are used to deliver the CAP transdermally along with an immune checkpoint inhibitor for enhancing transdermal treatment efficacy. The hollow-structured microneedle patch can facilitate the transportation of CAP through the skin, causing tumor cell death. The release of cancer antigens then promotes the maturation of dendritic cells in the tumor-draining lymph nodes, subsequently initiating the T cell-mediated immune response. Anti-PDL1 antibody (aPDL1), an immune checkpoint inhibitor (or other immune checkpoint inhibitors), released from the microneedle patch (in some embodiments) further augments the anti-tumor immunity. The transdermal combinational CAP and ICB therapy inhibits tumor growth for both primary tumors as well as distant tumors, with prolonged survival in the tumor-bearing mice. Such results should translate to other species.

  • Publication number: 20220160841
    Abstract: A closed-loop insulin delivery system is described. More particularly, the presently disclosed insulin delivery system can comprise glucose-responsive vesicles that release insulin in response to hypoxia triggered by enzymatic reduction of glucose. In addition or as an alternative to insulin, the delivery system can release other diabetes treatment agents, such as non-insulin-based diabetes treatment agents. The vesicles can be prepared from a hypoxia sensitive polymer, such as a hypoxia-sensitive hyaluronic acid (HS-HA). The HS-HA can comprise hydrophobic groups that can be reduced in hypoxic environments to form hydrophilic groups. The vesicles can be loaded into microneedles and microneedle array patches for use in the treatment of diabetes or to otherwise regulate blood glucose levels in subjects in need of such treatment.
