Induced Pluripotent Stem Cells Generated Using Lentivirus-Based Reprogramming

Description of Technology: Five human induced pluripotent stem cells (iPSC) lines are generated using lentivirus-based reprogramming technology. These lines are pluripotent, meaning they have the potential to differentiate into all cells in the body, and theoretically can proliferate/self-renew indefinitely. The iPSC lines are: NC1 (derived from female's fibroblasts), NC2 (derived from female's fibroblasts), NC3 (derived from male's HUVECS), NC4 (derived from male's fibroblasts) and NC5 (derived from female's fibroblasts). Further details of these cells are available upon request. NC1 uses a retrovirus delivery system incorporating the following vectors: pMIG-hKLF4, pMIG-hOCT4, pMIG-hSOX2, and MSCV h c-MYC IRES GFP. NC2-NC5 use the hSTEMCCA-loxP lentivirus delivery system (a gift from Dr. Gustavo Mostoslavsky). These cell lines will be useful for studies related to stem cell biology, understanding diseases, potential cell therapies, and small molecule screening.

Potential Commercial Applications: The iPSCs of this technology are useful:

(a) To study the biology of stem cell development,

(b) as controls in studies to screen for small molecules to change cell fate and/or to alleviate the phenotypes of various diseases, and

(c) to test different characterization and differentiation assays.

Competitive Advantages:

  • These cells can serve as control cells and, thus, significantly reduce the cost of initiating many research projects.
  • These cells can be a good source of control cells.

Development Stage:

  • Prototype
  • Pilot
  • Early-stage
  • In vitro data available

Stapled Peptides for Treatment of Cardiovascular Diseases and Inflammation

Description of Technology: The invention is directed to small molecule mimetics of apolipoproteins that have an inter-helical hydrocarbon bond, which stabilizes helix formation.

Apolipoproteins facilitate the transport of lipids and cholesterol in the body. Mimetics of apolipoproteins have been used to treat cholesterol-related disorders. However, these mimetics are susceptible to degradation in biological fluids and as a result, their ability to bind cholesterol becomes diminished over time.

Scientists at NHLBI have devised methods to stabilize and improve the performance of apolipoprotein mimetic peptides, using a modified hydrocarbon chain (“stapled apolipoproteins”). These stapled apolipoproteins are superior to singular apolipoproteins in that they are more resistant to enzymatic degradation and efflux a greater amount of cellular cholesterol.

Stapled apolipoproteins can be used in the treatment of cardiovascular diseases, particularly for treatment of atherosclerosis.

Potential Commercial Applications:

  • Treatment of inflammation and cardiovascular diseases, including hyperlipidemia, atherosclerosis, restenosis, and acute coronary syndrome.
  • Inclusion in oral, intravenous or transdermal peptide formulations.

Competitive Advantages:

  • Stapled apolipoproteins are more resistant to proteolysis and display enhanced bioavailability.
  • Stapled apolipoproteins are amenable to oral delivery and have increased permeability to the blood brain barrier.

Development Stage:

  • Pre-clinical
  • In vitro data available
  • In vivo data available (animal)

Parvovirus B19 Vaccine

Description of Technology: Parvovirus B19 (B19V) infection causes fifth disease, a disease characterized by rashes to the face and other parts of the body that primarily affects children. However, adults can also develop fifth disease and it can lead to more severe conditions. Patients that are immunocompromised, such as those who are HIV infected, organ transplant recipients, and cancer patients, can be particularly susceptible to more severe outcomes from B19V infection. Infection can also cause anemia and in pregnant women, it can lead to hydrops fetalis.

The subject technologies are expression vectors for the production of B19V VP1 and VP2 capsid proteins. Co-expression of the two proteins produce empty virus-like particles (VLPs) that can be used to develop a vaccine against parvovirus B19 and a packaging system for infectious B19V virus. Different expression vectors have been developed and optimized for expression in insects cells and more recently in mammalian cell lines such as 293, Cos7, Hela cells and 293T cells.

Potential Commercial Applications: Vaccine against parvovirus B19V.

Competitive Advantages: There is currently no B19V vaccine on the market.

Development Stage:

  • Early-stage
  • Pre-clinical
  • Clinical
  • In vitro data available
  • In vivo data available (animal)
  • In vivo data available (human)
