Landmarks in the historical development of gene therapy and its application to neurologic disorders are shown in Table 1. Major developments in gene therapy introduction therapy are currently taking place in the industrial sector, and the technologies of various companies have been reviewed elsewhere Jain Gene therapy involves the addition of a healthy, working copy gene therapy introduction the gene into appropriate cells in the body to replace or override the faulty copy present in the genome.

Unlike most conventional medicines, instead of treating the symptoms of a disease, gene therapy has the potential to correct the underlying cause.

Introduction to Gene Therapy

There are four major cell types in the nervous system note that astrocytes, oligodendrocytes, and microglial cells are collectively known as glial cells: Neurons — the nerve cells with connecting processes called axons. The communication points between neurons are called synapses. Astrocytes — these are the supporting cells in gene therapy introduction brain, assisting the functioning of neurons.

Oligodendrocytes — these cells provide the 'wire insulation' to the neuron axons in the form of myelin gene therapy introduction. Microglia — these are the CNS white blood cells and are derived from the bone marrow. Their turnover is over a one to two year period.

Gene therapy

Note that one important type of neuron in the spinal cord responsible for control of muscles is called the anterior horn cell. Autosomal recessive, gene therapy introduction dominant, X-linked.

These terms are used to describe the common modes gene therapy introduction inheritance for genetic disorders. Autosomal recessive — where a genetic disorder requires both copies of a gene to be abnormal to cause the disease.

An Introduction to Gene Therapy

Gene therapy of the human retina Leber's congenital amaurosis is an inherited gene therapy introduction disease caused by mutations in the RPE65 gene. The results of a small clinical trial in children were published in April. In May two more groups reported positive results in independent clinical trials using gene therapy to treat the condition.

In all three clinical trials, patients recovered functional vision without apparent side-effects. Cone function and day vision were restored for at least 33 months in two young specimens. The therapy was less efficient for older dogs. Gene therapy introduction a third of the hemoglobin contained the form introduced by the viral vector and blood gene therapy introduction were not needed.

This cure was accepted by the medical community in In August two of three subjects of a pilot study were confirmed to have been cured from chronic lymphocytic leukemia CLL.

The therapy used genetically modified T cells to attack cells that expressed the CD19 protein gene therapy introduction fight the disease.

The treatment used Alipogene tiparvovec Glybera to compensate for lipoprotein lipase gene therapy introductionwhich can cause severe pancreatitis. The researchers believed that the patients' immune systems would make normal T-cells and B-cells after a couple of months.

They were also given bone marrow. One patient relapsed and died and one died of a blood clot unrelated to the disease. The therapy was designed to increase the gene therapy introduction of SERCA 2, a protein in heart muscles, improving muscle function.

Three of the children had metachromatic leukodystrophywhich causes children to lose cognitive and motor skills. A drawback of this method is that it can be used only with certain tissues and the amount of DNA required is relatively large.

Another approach calls for the creation of a liposome which carries the therapeutic DNA in its aqueous core. Its advantage is that it can pass the gene therapy introduction genes through the membranes of the target cells. Another alternative, although less effective, is the chemical linking of the DNA to a molecule that binds to the cell receptors and from there the DNA gene therapy introduction transferred through the cell membrane to inside the target cell.
