Adeno-associated viruses (AAV) are used in gene delivery, but with limited success due to toxicity. The novel AAVs described in this technology may be more effective and useful in gene therapy applications.

The invention described and claimed in this patent application relates 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 Adeno-Associated Virus of serotype 4 (AAV4). The particular target cells identified are the ependymal cells of the brain. The methods described herein may be useful in carrying out gene therapy for diseases of the brain or central nervous system.

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.

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.

Many individuals with ongoing and severe dental problems are faced with the prospect of permanent tooth loss. Examples include dentinal degradation due to caries or periodontal disease; (accidental) injury to the mouth; and surgical removal of teeth due to tumors associated with the jaw. Clearly, a technology that offers a possible alternative to artificial dentures by designing and transplanting a set of living teeth fashioned from the patient's own pulp cells would greatly improve the individual's quality of life.

Due to the disorganized nature of blood vessels that run through tumors, chemotherapeutic agents often fail to penetrate tumors and kill cancer cells at the tumor’s center. This can lead to ineffective chemotherapeutic treatments, because tumors can quickly grow back if the entire tumor is not destroyed. NIH researchers have developed a therapeutic agent that solves this problem facing current chemotherapy treatments.

Enteric viruses like norovirus, rotavirus and astrovirus mainly transmit through fecal-oral route by ingestion of contaminated food and water and productively replicate in the intestines. Recently, researchers at National Heart, Lung, and Blood Institute (NHLBI) and National Institute of Dental and Craniofacial Research (NIDCR) identified a second route of enteric viral transmission by demonstrating that these viruses also productively and persistently infect salivary glands, reaching titers comparable to that in intestines.

This technology includes a sensitive and specific method to rapidly detect antibodies in biofluids. This assay has been used for the detection of antibodies in blood, urine, and saliva. Until now, no one has used LIPS to detect clinically relevant antibodies to SARS-CoV-2 Nucleocapsid (N) or Spike (S) in saliva. Briefly, LIPS employs recombinantly synthesized target proteins or peptides (e.g., S and N proteins) tagged with light-emitting proteins as targets to be captured by host produced immunoglobulins. These immunoglobulins can be captured by protein A/G beads and immobilized.

This technology includes an immunoassay to measure SARS-CoV-2 antibodies against the nucleocapsid and spike proteins.
