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.

Two broadly neutralizing antibodies show great promise to provide long-acting immunity against COVID-19 in immunocompromised populations according to a paper published June 15 in the Journal of Experimental Medicine (JEM). The antibodies were effective against all SARS-CoV-2 variants of concern tested and could be used alone or in an antibody cocktail to diminish the risk of infection.

A new study from Tel Aviv University offers a new and unique treatment for AIDS which may be developed into a vaccine or a one time treatment for patients with HIV. The study examined the engineering of type B white blood cells in the patient's body so as to secrete anti-HIV antibodies in response to the virus.
