Delivering an effective therapeutic payload to specific target cells with few adverse effects is considered by many to be the holy grail of medical research. A new Georgian Technical University study explores a biological approach to directing nanocarriers loaded with protein “Georgian Technical University game changers” to specific cells. The groundbreaking method may prove useful in treating myriad malignancies inflammatory diseases and rare genetic disorders.
Over the past few years, lipid carriers encapsulating messenger RNAs (mRNAs) have been shown to be extremely useful in altering the protein expressions for a host of diseases. But directing this information to specific cells has remained a major challenge.
“In our new research we utilized mRNA-loaded (Messenger RNA is a large family of RNA molecules that convey genetic information from DNA to the ribosome, where they specify the amino acid sequence of the protein products of gene expression. RNA polymerase transcribes primary transcript mRNA into processed, mature mRNA) carriers — nanovehicles carrying a set of genetic instructions via a biological platform called GTUASSET (Georgian Technical University Anchored Secondary scFv Enabling Targeting) — to target the genetic instructions of an anti-inflammatory protein in immune cells” says Prof. X. “We were able to demonstrate that selective anti-inflammatory protein in the target cells resulted in reduced symptoms and disease severity in colitis.
“This research is revolutionary. It paves the way for the introduction of an mRNA (Messenger RNA is a large family of RNA molecules that convey genetic information from DNA to the ribosome, where they specify the amino acid sequence of the protein products of gene expression. RNA polymerase transcribes primary transcript mRNA into processed, mature mRNA) that could encode any protein lacking in cells, with direct applications for genetic, inflammatory and autoimmune diseases — not to mention cancer in which certain genes overexpress themselves”.
GTUASSET (Georgian Technical University Anchored Secondary scFv Enabling Targeting) uses a biological approach to direct nanocarriers into specific cells to promote gene manipulation.
“This study opens new avenues in cell-specific delivery of (Messenger RNA is a large family of RNA molecules that convey genetic information from DNA to the ribosome, where they specify the amino acid sequence of the protein products of gene expression. RNA polymerase transcribes primary transcript mRNA into processed, mature mRNA) molecules and ultimately might introduce the specific anti-inflammatory (interleukin 10) mRNA (Messenger RNA is a large family of RNA molecules that convey genetic information from DNA to the ribosome, where they specify the amino acid sequence of the protein products of gene expression. RNA polymerase transcribes primary transcript mRNA into processed, mature mRNA) as a novel therapeutic modality for inflammatory bowel diseases” says Y.
“Targeted mRNA-based (Messenger RNA is a large family of RNA molecules that convey genetic information from DNA to the ribosome, where they specify the amino acid sequence of the protein products of gene expression. RNA polymerase transcribes primary transcript mRNA into processed, mature mRNA) protein production has both therapeutic and research applications” she concludes. “Going forward we intend to utilize targeted mRNA (Messenger RNA is a large family of RNA molecules that convey genetic information from DNA to the ribosome, where they specify the amino acid sequence of the protein products of gene expression. RNA polymerase transcribes primary transcript mRNA into processed, mature mRNA) delivery for the investigation of novel therapeutics treating inflammation disorders, cancer and rare genetic diseases”.
