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.

A new study that analyzed protein levels in 2,002 primary tumors from 14 tissue-based cancer types identified 11 distinct molecular subtypes, providing systematic knowledge that greatly expands a searchable online database that has become a go-to platform for cancer data analysis by users worldwide.

UNC Lineberger Comprehensive Cancer Center's Hanna K. Sanoff, MD, MPH, is the author of a viewpoint in the New England Journal of Medicine that provides a perspective on the evolving treatment of rectal cancer. She offers prospects for future treatment of the disease in light of encouraging findings from a study published in the journal that found the immunotherapy drug dostarlimab was especially effective in a phase II clinical trial of a dozen patients with a subtype of rectal cancer.
