  • Publication number: 20210008039
    Abstract: The present invention relates to the use of an Angiotensin II type 1 (AT1) receptor blocker for promoting sleep and/or the treatment of insomnia. It is based, at least in part, on the results of experiments performed using a validated rat model of stress-induced insomnia in which candesartan was found to ameliorate sleep disturbances induced by stress. Further, it was observed that this effect seems to be caused by blockade of AT1 receptors located in several brain regions that are key components of the neural circuitry activated during insomnia. In contrast to currently marketed treatments for insomnia, the AT1 receptor blocker was found to restore normal sleep without inhibiting REM sleep and/or inducing atypical wave components in the EEG.

  • Publication number: 20210000602
    Abstract: The invention relates generally to generation of biomimetic scaffolds for bone tissue engineering and, more particularly, to multi-level lamellar structures having rotated or alternated plywood designs to mimic natural bone tissue. The invention also includes methods of preparing and applying the scaffolds to treat bone tissue defects. The biomimetic scaffold includes a lamellar structure having multiple lamellae and each lamella has a plurality of layers stacked parallel to one another.

  • Publication number: 20210000858
    Abstract: Corneal stromal scars are the leading cause of corneal blindness. The present invention relates to methods and compositions useful in therapies for this pathological condition. The invention provides corneal stromal stem cells and certain other stem cells and as well as exosome polynucleotides produced by such cells, and methods for making and using these cells and compositions. The invention is based upon the discovery that exosomes and their associate active components obtained from these cells comprise agents having the same capacity as corneal stromal stem cells to reduce scarring and prevent scar formation in patients having corneal damage.

  • Publication number: 20200405644
    Abstract: The absence of regulatory T cells (Treg) may underlie disorders including but not limited to autoimmunity, dermatitis, periodontitis and even transplant rejection. Enhancing local numbers of Treg through in situ Treg expansion or induction is contemplated herein as a treatment option for these disorders. Current methods for in vivo Treg expansion are not Treg specific and are associated with many adverse side-effects. The data presented herein provides in vitro testing of a Treg-inducing microparticle providing a predictable controlled release for combinations of cytokines and drugs (e.g., IL-2, TGF-?, and/or rapamycin) resulting in targeted Treg migration. These controlled release microparticles are also capable of inducing FoxP3+ Treg in human cells in vitro suggesting that these compositions be developed into an in vivo Treg induction and expansion therapy.

  • Publication number: 20200405916
    Abstract: Methods of regenerating vital tooth tissue in situ after endodontic therapy include introducing a hydrogel scaffold into a root canal of a tooth in a patient after native pulp has been removed from the root canal. The hydrogel scaffold may comprise a sponge scaffold, and can be acellular. The hydrogel scaffold can contain chemotactic, angiogenic, neurogenic, and/or immunomodulatory biofactors that cause infiltration of endogenous cells from the patient into the root canal. Alternatively, such biofactors/drugs can be administered to the patient separately from the hydrogel scaffold. The hydrogel scaffold can fill the periapical space of an abscessed root.
