Nanoparticle vaccine could curb cancer metastasis to lungs by targeting a protein

UC San Diego engineers have developed an experimental vaccine that could prevent the spread of metastatic cancers to the lungs. Its success lies in targeting a protein known to play a central role in cancer growth and spread, rather than targeting the primary tumor itself.

Tuberculosis Therapy: Smallest Particles Will Deliver the Drug to the Lungs in Future

Therapy of the dangerous infectious disease of tuberculosis faces the challenge of pathogens frequently being resistant to several common antibiotics. Researchers of Karlsruhe Institute of Technology (KIT) have now developed nanoparticles to deliver new antibiotics directly to the lungs in future. Surfactants ensure that the highly fat-soluble antibiotics disperse very finely in water and can be inhaled. First tests at the Research Center Borstel, Leibniz Lung Center, reveal a high effectiveness and good compatibility of the nanocarriers of antibiotics. The researchers report in ACS Nano.

Ask the expert: What are nanomedicines?

Morteza Mahmoudi, an assistant professor in MSU’s Department of Radiology, explains why addressing disagreements with stronger standards will help ensure future nanomedicines are safe, effective and successful.

Fixing Spinal Cord Injuries With ‘Dancing Molecules’

Researchers have created an injectable therapy for spinal cord injuries that uses specially engineered molecules that trigger a healing response in spinal cells. These molecules come together to form tiny fibers in a liquid solution. Scientists can control the motion of these fibers, allowing the fibers to connect more effectively with cells in the spine. The research may lead to a cure for spinal injuries in humans.

Study finds nanomedicine targeting lymph nodes key to triple negative breast cancer treatment

Research from the University of Michigan Rogel Cancer Center could provide a new approach to treating an aggressive form of breast cancer. A study led by Duxin Sun, Ph.D., found that targeting the immune microenvironment in lymph nodes and tumors simultaneously led to long-term tumor remission in mice models of metastatic triple negative breast cancer.

Research News Tip Sheet: Story Ideas from Johns Hopkins Medicine

Technion Harvey Prize Honors Pioneers in Chemical Engineering and Medical Sciences

The prestigious prize for 2019-2020 goes to Professor Joseph DeSimone of Stanford University for significant contributions to materials science, chemistry, polymer science nano medicine, and 3D printing; and to Professor Raphael Mechoulam of the Hebrew University of Jerusalem for the discovery of the active molecules in cannabis

Brain’s Immune Cells Promising Cellular Target for Therapeutics

Inspired by the need for new and better therapies for neurodegenerative diseases, Rutgers University researchers are exploring the link between uncontrolled inflammation within the brain and the brain’s immune cells, known as microglia, which are emerging as a promising cellular target because of the prominent role they play in brain inflammation. In APL Bioengineering, the group highlights the design considerations and benefits of creating therapeutic nanoparticles for carrying pharmacological factors directly to the sites of the microglia.

Experiments in Mice And Human Cells Shed Light On Best Way to Deliver Nanoparticle Therapy For Cancer

Researchers in the cancer nanomedicine community debate whether use of tiny structures, called nanoparticles, can best deliver drug therapy to tumors passively — allowing the nanoparticles to diffuse into tumors and become held in place, or actively — adding a targeted anti-cancer molecule to bind to specific cancer cell receptors and, in theory, keep the nanoparticle in the tumor longer. Now, new research on human and mouse tumors in mice by investigators at the Johns Hopkins Kimmel Cancer Center suggests the question is even more complicated.

Nanoparticles Deliver ‘Suicide Gene’ Therapy to Pediatric Brain Tumors Growing in Mice

Johns Hopkins researchers report that a type of biodegradable, lab-engineered nanoparticle they fashioned can successfully deliver a “suicide gene” to pediatric brain tumor cells implanted in the brains of mice. The poly(beta-amino ester) nanoparticles, known as PBAEs, were part of a treatment that also used a drug to kill the cells and prolong the test animals’ survival.
