Abstract:
Some embodiments of the invention comprise methods, systems, and compositions to selectively induce, whether in vitro or in vivo, the neuronal differentiation of multipotent stromal cells through the application of microRNAs, including but not limited to miRNA-124, miRNA-137 and/or miRNA-9* expression products of those miRNAs, and molecules and compositions containing functional elements of those miRNAs. Some embodiments of the invention also comprise the therapeutic administration and use of such induced cells to treat mammalian injuries and diseases, including but not limited to, nervous system injuries or diseases that may otherwise result in decreased cell or system function.
Abstract:
A method of generating a population of cells useful for treating a brain disorder in a subject is disclosed. The method comprises contacting mesenchymal stem cells (MSCs) with at least one exogenous miRNA having a nucleic acid sequence at least 90% identical to a sequence selected from the group consisting of SEQ ID NOs: 15-19 and 27-35, thereby generating the population of cells and/or generating neurotrophic factors that may provide important signals to damaged tissues or locally residing stem cells. MSCs differentiated by miRs may also secrete miRs and deliver them to adjacent cells and therefore provide important signals to neighboring endogenous normal or malignant cells.

Abstract:
Therapeutic compounds based on synthetic sphingolipid analogs are provided, particularly alkylthiophenyl substituted ceramide analogs, suitable for treating degenerative, infectious, and other diseases.
Abstract:
A composition comprising bone marrow cells (BMC) and demineralized bone matrix (DBM) and/or mineralized bone matrix (MBM), optionally comprising bone morphogenetic protein (BMP), particularly for use in bone marrow transplantation, into bone marrow cavity or into extraskeletal sites, and methods of transplantation/implantation thereof. The composition and methods of the invention enable restoring and/or enhancing the formation of hematopoiectic microenvironment originating from the transplanted BMC, and are useful in the treatment of hematopoietic disorders, such as deficiency of stem cells and/or their products, genetic conditions resulting in abnormal stem cells and/or products, or hematopoietic disorders of malignant or non-malignant origin. The composition and method of the invention may also be used for the induction of graft tolerence, for the prevention of graft-v-host disease. It is mostly important that the compositions and methods of the invention may be applied for the treatment of diseases affecting primarily or secondarily the stromal microenvironment that supports and regulates hematopoiesis. Further provided is a kit for transplantation into a mammal of BMC in admixture with DBM and/or MBM.
Abstract:
The present invention features a method of inducing donor-specific tolerance in a host. Tolerogenic treatments of the present invention may be administered to a host prior to transplantation of donor-derived materials. The tolerogenic treatment involves (1) administering an immunosuppressive agent to a host mammal in a non-myeloablative regimen sufficient to decrease, but not necessarily to eliminate, the host mammal's functional T lymphocyte population; (2) infusing donor antigens from a non-syngeneic donor into the host mammal; (3) eliminating those host T lymphocytes responding to the infused donor antigens using a non-myeloablative dose of lymphocytotoxic or tolerizing agent; and (4) administering donor hematopoietic cells to the host mammal. Donor lymphoid cells used for cell therapy of a host mammal can be depleted of host specific immunological reactivity by methods essentially similar to those use for tolerizing a host mammal prior to transplantation.
Abstract:
Immunotherapeutic Monoclonal Antibody Complexes or Conjugates (IMAC) comprising readily accessible antibodies designed and approved for clinical use are provided using a one-step method that combines killing of existing cancer cells in parallel with induction of long-lasting anti-cancer vaccination. Methods for their use, alone or in combination with cancer killer cells including intentionally mismatched donor T cells, NK cells concomitantly with additional anti-cancer or immune activating agents, or activation of patient's own immune system for personalized treatment of cancer and elimination of undesirable non-malignant cells are also provided. In addition, treatment method based on IMAC can be applied for in vivo vaccination against cancer using an existing malignant lesion as internal anti-cancer vaccine by engagement of patients antigen presenting cells for induction of long-lasting anti-cancer vaccination in situ against residual or recurrent disease.
Abstract:
The present invention is directed to use of a series of compounds and compositions comprising the same for activating telomerase and treating diseases, disorders and/or conditions related thereto.
Abstract:
The present invention provides new ceramide analogs indicated as the compounds of formula (II). These novel analogs exhibit a significant anti cancerous effect and are therefore provided as a pharmaceutical composition for treating cell proliferative diseases, neurodegenerative disorders, metabolism-associated conditions, infectious diseases, and immune-related disorders. The invention further provides combined compositions and kits combining the novel ceramide analogs of formula (II) with an additional therapeutic agent.
Abstract:
The present invention relates to a novel class of tri-aryl compounds, compositions comprising the same and processes for the preparation thereof.
