Abstract: This disclosure is directed to therapeutic compositions, and more particularly to microparticle compositions for the controlled delivery of telmisartan and actinomycin D.

Abstract: A nanosystem and methods of treating, including prophylactically, coronavirus infections, such as those caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), by administering such nanosystem to a patient is presented. The nanosystem may be comprised of a single or a combination of therapeutic agents, optionally encapsulated in a nanoparticle having a targeting moiety directed to the particular coronavirus. For CoV-2 infections, at least one therapeutic agent, such as the dual DPP4/ACE2 inhibitor sitagliptin, may optionally be encapsulated within a nanoparticle having a fatty acid such as linoleic acid, as the targeting moiety. Administration can occur intranasally prior to infection for prophylactic treatment or post-infection for treatment of the viral infection.

Abstract: A multi-functional broad-spectrum antiviral and anti-inflammatory nanosystem and methods of treating, including prophylactically, coronavirus infections, such as those caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), by administering such nanosystem to a patient is presented. The nanosystem may be comprised of a combination of therapeutic agents directed to the particular coronavirus encapsulated in a nanoparticle that is surface coated with a targeting moiety. For CoV-2 infections, an antiviral such as the PPAR-? agonist leriglitazone (LG) and an siRNA targeting a conserved sequence of the virus can be encapsulated within a nanoparticle surface coated with a fatty acid such as linoleic acid, as the targeting moiety. Administration can occur intranasally prior to infection for prophylactic treatment or post-infection for treatment of the viral infection.

Abstract: This invention provides for a RSV-targeted nanoparticle PMN (RTPMN), combining HR2D anti-fusion peptide, and plasmid encoded siRNA against RSV-NS1 and/or RSV-P gene as a safe, effective and inexpensive anti-RSV prophylaxis and/or therapy.

Abstract: The preparation of dual functionalized nanoparticles is generally provided along with their application. The dual functionalized nanoparticles provide dual targeting and can effectively pass the blood brain barrier and target brain tissue. The dual targeted and dual responsive nanoparticles are functionalized to include at least two different ligands that are capable of transport across the blood brain barrier. The nanoparticles can be prepared from polymeric materials that can be biocompatible, provide long circulation life in a body, and be successfully ligated to both functionalities by use of acid-sensitive and/or redox potential-sensitive bonds for delivery across the blood brain barrier and delivery of a payload to brain tissue.

Abstract: A multifunctional dendrimer nanoparticle and method of treating diseases of the posterior segment of the eye is presented. The functionalized polyamidoamine (PAMAM) dendrimer effectively delivers drugs and/or genes to the posterior eye, thereby providing for the effective, non-invasive, and topical treatment of diseased in the posterior eye. The multifunctional dendrimer nanoparticle has shRNA-encoding DNA and small molecule drug encapsulated cyclodextrin complexed to the outer surface of the dendrimer for delivery to the posterior segment of the eye.

Abstract: The present disclosure relates to compositions and uses thereof for preventing and treating respiratory syncytial vims (RSV) infection. In some aspects, disclosed herein is a method for preventing or treating respiratory syncytial vims (RSV) infection in a subject, comprising administering to the subject a therapeutically effective amount of a composition comprising a short-chain fatty acid.

Abstract: Compositions and methods for treating traumatic brain injury (TBI) are presented. Novel dendriplexes are formed from poly(amidoamine) (PAMAM) dendrimers complexed with shRNA encoding DNA plasmids encapsulating shRNA encoding chemokine ligand 20 (CCL20) gene, chemokine receptor 6 (CCR6) gene, or a combination thereof. The dendriplexes are dually administered, both intranasally and intravenously, prior to administration of stem cells, such as human mesenchymal stem cells (hMSCs) for the treatment of traumatic brain injury (TBI). Administration of the dendriplexes prior to stem cell administration resulted in a decrease in neurodegeneration, neuroinflammation, microgliosis and astrogliosis. In addition, a synergistic increase in brain derived trophic factor (BDNF) was shown by administration of the combination of dendriplex and stem cell administration.
