Disease Focus: Immune Disease
Prospective isolation of hESC-derived hematopoietic and cardiomyocyte stem cells
The capacity of human embryonic stem cells (hESCs) to perpetuate themselves indefinitely in culture and to differentiate to all cell types of the body has lead to numerous studies that aim to isolate therapeutically relevant cells for the benefit of patients, and also to study how genetic diseases develop. However, hESCs can cause tumors called […]
Human Embryonic Stem Cell Therapeutic Strategies to Target HIV Disease
AIDS is a disease that currently has no cure. It arises when the human immunodeficiency virus (HIV) infects certain types of blood cells. These cells would normally be used to fight infection, but instead are destroyed by the virus, leading to immunodeficiency. We have recently been able to induce the development of human embryonic stem […]
Human stem cell derived oligodendrocytes for treatment of stroke and MS
Strokes that affect the nerves cells, i.e., “gray matter”, consistently receive the most attention. However, the kind of strokes that affecting the “wiring” of the brain, i.e., “white matter”, cause nearly as much disability. The most severe disability is caused when the stroke is in the wiring (axons) that connect the brain and spinal cord; […]
Human Embryonic Stem Cells and Remyelination in a Viral Model of Demyelination
Multiple sclerosis (MS) is the most common neurologic disease affecting young adults under the age of 40 with the majority of MS patients diagnosed in the second or third decade of life. MS is characterized by the gradual loss of the myelin sheath that surrounds and insulates axons that allow for the conduction of nerve […]
Embryonic stem cell-derived thymic epithelial cells
The function of the immune system throughout life is essential for protection from infections and cancer. T lymphocytes are white blood cells that choreograph the multiple responses that the body uses to control infection. T lymphocytes are produced in the thymus, a specialized organ located in the chest in front of the heart. The production […]
Genetic modification of the human genome to resist HIV-1 infection and/or disease progression
The proposed studies describe the genetic approaches utilizing human embryonic stem cells to suppress and/or eliminate the expression of the human protein CCR5. CCR5 is found on the surface of white blood cells. HIV-1 attaches to CCR5 and uses CCR5 to enter into its target cells. Our approach is to utilize established as well as […]
HPSC based therapy for HIV disease using RNAi to CCR5.
RNA interference is a naturally occurring means to block the function of genes in our body. We propose that RNA interference can be used to block HIV-1 infection and its reproduction within the body. When RNA interference is introduced into a stem cell, its blocking activity will be present throughout the lifetime of the stem […]
ZINC FINGER NUCLEASE-BASED STEM CELL THERAPY FOR AIDS
Some years ago it was discovered that patients homozygous for a natural mutation (the Δ32 mutation) in the CCR5 gene are generally resistant to HIV infection by blocking virus entry to a cell. Building on this observation, a study published in 2009 reported a potential “cure” in an AIDS patient with leukemia after receiving a […]
A phase 1/2 study to evaluate a bispecific CD19/CD20-directed CAR T cell, in refractory lupus nephritis and systemic lupus erythematosus
Anti-HIV duoCAR-T cell therapy for HIV infection
The University of California San Francisco (UCSF) is conducting a clinical trial that modifies a patient’s own immune cells in order to treat and potentially cure HIV. Current treatment of HIV involves the use of long-term antiretroviral therapy (ART). However, many people are not able to access and adhere to long-term ART. The team will […]
