New lipid nanoparticle platform delivers mRNA to the brain through the blood-brain barrier

Science Daily: Pharmacology News

Scientists have developed a lipid nanoparticle system capable of delivering messenger RNA (mRNA) to the brain via intravenous injection, a challenge that has long been limited by the protective nature of the blood-brain barrier.

Editing without 'cutting': Molecular mechanisms of new gene-editing tool revealed

Science Daily: Pharmacology News

Functional analysis based on these structures also revealed how a 'prime editor' could achieve reverse transcription, synthesizing DNA from RNA, without 'cutting' both strands of the double helix. Clarifying these molecular mechanisms contributes greatly to designing gene-editing tools accurate enough for gene therapy treatments.

Researchers map communities of single cells in metastatic breast cancers

Broad Institute

The results pave the way for future single-cell or spatially resolved studies that look at how cells surrounding a metastatic tumor impact its progression or treatment outcomes. Eventually, we hope that these methods can help inform the development of drugs or even guide patients’ individual treatments.”

Why brain cancer is often resistant to immunotherapy

Broad Institute

They also found that patients treated with dexamethasone, a common treatment for brain cancer patients, showed signs of one of the immunosuppressive programs, suggesting that this drug could reduce the effectiveness of immunotherapy. To do this, the team used a different approach to single-cell analysis.

New approach may yield modified messenger RNAs for treating a wide range of conditions

Broad Institute

Using what they learned from these experiments, they developed a framework — ligation-enabled messenger RNA-oligonucleotide assembly, or LEGO — that enables researchers to chemically modify the structure of mRNA molecules and influence their interactions with the cell's protein-translation machinery, achieving desired therapeutic effects.
