Co-Administration Enhances Nanoparticle Immunotherapy

Cancer researchers found that virus-nanoparticle-based anticancer immunotherapy was more effective when the drug doxorubicin was administered simultaneously with the particles rather than using the particles as carriers of the drug. More...

Bifunctional Nanoparticles Show Potential in Cancer Models

To be successful, an immunotherapeutic approach for treating cancer must overcome the immunosuppressive effects of the tumor microenvironment; a novel bifunctional nanoparticle does just that. More...

Stem Cell and 3D Printing Generate Viable Tissue

A team of Swedish cell biologists combined three-dimensional (3D) bio-printing with advanced stem cell technology to create viable cultures of cartilage tissue that had cellular and mechanical properties similar to patients’ natural cartilage. More...

Modified Stem Cells Used to Correct Arthritis Inflammation

Researchers have used CRISPR/Cas9 genome editing technology to create mouse stem cells able to infiltrate the joints, form cartilage tissue, and correct the autoimmune defects that are responsible for arthritis. More...

Gene Editing Restores Vision in Mouse RP Models

The CRISPR/Cas9 gene-editing tool was used to reprogram defective optical rod photoreceptor cells and transform them into functioning cone photoreceptors, which restored impaired vision in two mouse models of retinitis pigmentosa. More...

Miniaturized Gene Editing for Treatment of Macular Regeneration

A viral vector was used to insert a very small CRISPR/Cas9 gene-editing tool into mouse muscle cells or retinal pigment epithelium cells, where it induced mutations that partially cured laser damage that mimicked human chronic age-related macular degeneration. More...

Link Between Aging and Fibrotic Pulmonary Disease Discovered

A study analyzing transcriptome biomarker data has shown evidence linking cellular senescence with idiopathic pulmonary fibrosis (IPF), suggesting that this fatal lung disease maybe involve a form of accelerated aging. More...
