Researchers have created an inhalable COVID-19 vaccine that is shelf stable at room temperature for up to three months, targets the lungs specifically and effectively, and allows for self-administration via an inhaler. The researchers also found that the delivery mechanism for this vaccine - a lung-derived exosome called LSC-Exo - is more effective at evading the lung's mucosal lining than the lipid-based nanoparticles currently in use, and can be used effectively with protein-based vaccines.

Researchers from Rice University and the University of Texas MD Anderson Cancer Center have discovered potential new drugs that work in concert with other drugs to deliver a deadly one-two punch to leukemia.

The potential drugs are still years away from being tested in cancer patients, but a recently published study in the journal Leukemia highlights their promise and the innovative methods that led to their discovery.

Researchers at Karolinska Institutet in Sweden have linked resistance to treatment for a deadly form of kidney cancer to low mitochondrial content in the cell. When the researchers increased the mitochondrial content with an inhibitor, the cancer cells responded to the treatment. Their findings, which are published in Nature Metabolism, offer hope for more targeted cancer drugs.

An oral antiviral drug that targets a key part of the respiratory syncytial virus (RSV) polymerase and inhibits the synthesis of viral genetic material has been identified, a finding that could provide an effective treatment against RSV disease, according to researchers in the Center for Translational Antiviral Research at Georgia State University.

Biomarkers that could be targets for novel drugs to treat glioblastoma brain tumors have been identified by investigators at Georgetown Lombardi Comprehensive Cancer Center, providing hope for a cancer that is highly lethal.

Currently, the drug most often used to treat glioblastoma, temozolomide, is uniquely able to cross the blood/brain barrier to attack the tumor but resistance develops rapidly, and many patients do not survive for more than a year after diagnosis.

Paxlovid is the leading oral medication for preventing severe cases of COVID-19 in high-risk individuals. However, symptoms returned in some patients after treatment was completed, prompting the Centers for Disease Control and Prevention (CDC) to issue a health advisory on this so-called "COVID-19 rebound."

Most skin cancer drugs that activate the immune system work by triggering immune cells, called T cells, to attack tumors, but when T cells are activated for too long, they can wear out and cease to function. A new study led by Penn State College of Medicine scientists finds that another type of immune cell - natural killer cells - can be harnessed to pick up the slack when T cells no longer work and may also reinvigorate T cells to attack melanoma tumors.
