The invention described and claimed in this patent application is related to the delivery of heterologous nucleic acids or genes to particular target cells. In particular, the application relates to methods of delivering a heterologous nucleic acid or gene of interest to particular target cells using an Adeno-Associated Virus of serotype 5 (AAV5). The particular target cells identified include the alveolar cells of the lung and cerebellar and ependymal cells of the brain.

This technology relates to the use of thymic stromal lymphopoietin (TSLP) to induce CD4+ T cell proliferation. This proliferation could be of particular relevance for patients in whom this cell population has been significantly reduced by HIV/AIDS or other conditions resulting in immunodeficiency. The proliferation of isolated CD4+ T cells can be induced through direct contact with TSLP or a nucleic acid encoding TSLP.

The invention described and claimed in this patent application provides for novel vectors and viral particles which comprise adeno-associated virus serotype 5 (AAV5). AAV5 is a single-stranded DNA virus of either plus or minus polarity which, like other AAV serotypes (e.g., AAV4, AAV2) requires a helper virus for replication. AAV type 2 has the interesting and potentially useful ability to integrate into human chromosome 19 q 13.3-q ter. This activity is dependent on the non-structural, Rep, proteins of AAV2.

The invention provides a method of diagnosing X-linked severe combined immunodeficiency (XSCID) in males or determining whether females are carriers. This method is based upon the presence of either a mutated or truncated IL-2Rgamma gene. The invention also discloses a method of treating XSCID as well as a method for monitoring the therapy.

This invention relates to a novel magnetic resonance angiography (MRA) method that accomplishes uniform contrast enhancement between coronary arteries and the surrounding tissue across the entire imaging volume. The disclosed technique utilizes an adiabatic refocusing transverse relaxation time (T₂)-preparation pulse sequence, in which the magnetization is tipped into the transverse plane with a hard radio-frequency (RF) pulse and refocused using a pair of adiabatic fast-passage RF pulses. The isochromats are subsequently returned to the longitudinal axis using a hard RF pulse.

Cytokines exert their respective biochemical and physiological effects by binding to specific receptor molecules, which then stimulate signal transduction pathways. Interleukin-21 (IL-21) is a type I cytokine whose receptor is expressed on T, B, and NK cells.

This invention is a method to significantly improve the temporal or spatial resolution in a phase contrast MRI (PC-MRI) study. In general, conventional PC-MRI involves encoding the motion information of spins in the phase of the image. The velocity of the spin motion can be extracted by calculating the phase difference between two consecutive images acquired with two different bipolar encoding gradients.

Approximately 30,000 patients are diagnosed with renal cell carcinoma (RCC) each year in the United States, and an estimated 12,000 patients die of this disease. Most patients are diagnosed with advanced local disease or metastatic disease. Metastatic RCC carries a poor prognosis with median survivals in the range of 10-12 months. Drugs that inhibit VEGF receptor tyrosine kinases such as Sorafenib and Sunitinib have recently been approved by the FDA to treat metastatic RCC.

Immuno-therapy has taken a lead among the new cancer therapeutic approaches. It is one of the most promising new therapeutic approaches that exploit the innate immune mechanism of an individual to fight against a certain disease.

Available for licensing and commercial development is a novel two-photon microscope system, which would allow improved fluorescent light collection, the use of less excitation power and deeper penetration of tissue and isolated cells. Multi-photon fluorescence microscopy (MPFM) is an imaging technique that can investigate biological processes to sub-cellular resolution at depths of hundreds of microns below the surface of biological tissues.
