Disease Focus: Immune Disease
Pre-clinical development of gene correction therapy of hematopoietic stem cells for SCID-X1
Severe combined immunodeficiency caused by mutations in the IL2RG gene on the x-chromosome (SCID-X1 or “bubble boy disease”) is a devastating genetic disease that results in boys not being able to form an immune system. If they are exposed to the environment for even a short period of time they can get infections that a […]
Generation of a functional thymus to induce immune tolerance to stem cell derivatives
Stem cell research offers the promise of replacing missing or damaged tissues in the treatment of disease. Stem-cell-derived transplants still face problems with rejection as in traditional organ transplants. Several drugs can prevent rejection but also suppress the immune system, leaving patients vulnerable to infections and cancer. To avoid rejection without using drugs requires re-educating […]
A monoclonal antibody that depletes blood stem cells and enables chemotherapy free transplants
Successful stem cell therapy requires the replacement of diseased or dysfunctional stem cells with healthy ones. These healthy stem cells can come from either a donor or can be stem cells that are modified by gene therapy techniques. One important step in this process of repair and replacement is to eliminate the existing diseased cells […]
Gene Correction of Autologous Hematopoietic Stem Cells in Artemis Deficient SCID
Artemis is a chemical in all cells in the body that is essential for the normal development of the immune system and repairing damaged DNA. Artemis deficiency (AD) causes Severe Combined Immunodeficiency (SCID-A), a “bubble baby” syndrome associated with increased sensitivity to radiation and chemotherapy. SCID-A is hard to treat with a bone marrow stem […]
A monoclonal antibody that depletes blood stem cells and enables chemotherapy free transplants
Successful stem cell therapy requires replacement of diseased or dysfunctional stem cells with healthy ones. These healthy stem cells can come from either a donor or can be stem cells that are modified by gene therapy techniques. One important step in this process of repair and replacement is to eliminate the existing diseased cells so […]
Development of RNA-based approaches to stem cell gene therapy for HIV
Despite significant advances in treatment and prevention programs, HIV infection with progression to Acquired Immunodeficiency Syndrome (AIDS) is still prevalent in California. The CDC Estimates >56,000 new cases of HIV infection each year in the US with over 148,000 cumulative cases reported in California alone (as of 2009). Multi-drug therapy has been helpful in reducing […]
Curing Hematological Diseases
The primary aim of this project is to develop treatments for incurable diseases of the blood and immune system. X-linked Severe Combined Immunodeficiency (X-SCID) and Fanconi anemia (FA) are two blood diseases where mutations in a single gene results in the disease. XSCID, more commonly known as the “bubble boy” disease, is characterized by a […]
Human Immune System Mouse models as preclinical platforms for stem cell derived grafts
A major obstacle to stem cell based therapies is the immune response of the patient to stem cell derived tissue, which can be recognized as foreign and attacked by the patient’s immune system. T cells orchestrate immune responses and are “educated” about self versus foreign in an organ called the thymus. It may be possible […]
Role of Innate Immunity in hematopoeitic stem cell-mediated allograft tolerance
The research proposed in this project has very high potential to identify new medications to boost the natural ability of stem cells to prevent rejection of transplanted organs. This is a very important goal, because patients that receive a life-saving transplanted organ must take toxic medications that increase their risk for cancer and serious infections. […]
Engineered immune tolerance by Stem Cell-derived thymic regeneration
Stem cell therapies have the potential to transform medicine by allowing the regeneration of tissues or organs damaged by disease or trauma. In order for stem cell therapies to proceed, it will be essential that the regulation of immune responses to the stem cell derived tissues be achieved. While the function of the immune system […]
