New biomarkers that predict HIV remission after antiretroviral therapy (ART) interruption are critical for the development of new therapeutic strategies that can achieve infection control without ART, a condition defined as functional cure. Wistar Scientists have identified metabolic and glycomic signatures in the blood of a rare population of HIV-infected individuals who can naturally sustain viral suppression after ART cessation, known as post-treatment controllers. T
Until now, systemic biomarkers to measure exercise effects on brain function and that link to relevant metabolic responses were lacking. A study shows a memory biomarker, myokine Cathepsin B (CTSB), increased in older adults following a 26-week structured aerobic exercise training. The positive association between CTSB and cognition, and the substantial modulation of lipid metabolites implicated in dementia, support the beneficial effects of exercise training on brain function and brain health in asymptomatic individuals at risk for Alzheimer’s.

Sylvester Comprehensive Cancer Center researchers are looking at ways to combine imaging and biomarkers to predict prostate cancer progression more accurately.
“There’s no place like home,” has its roots deep in the brain. Using fiber photometry, scientists are the first to show that home evokes a surge of dopamine in mice that mimics the response to a dose of cocaine. The study demonstrates how dopamine rises rapidly in mice moved from a simple recording chamber to their home cage, but less so when they return to a cage not quite like the one they knew.
Atlantic Health System is enrolling women in a landmark study that uses a simple blood test for the CA-125 protein to screen women who are at low risk for ovarian cancer. The purpose of the clinical trial is to help determine whether this test can catch ovarian cancer early in women who would not normally be screened for it. Atlantic Health System hospitals are the only centers in the New York metro region to participate in the study, and have the third highest enrollment numbers in the nation.
Neuro-oncologist and renowned physician-scientist Ingo Mellinghoff will lead MSK’s distinguished Department of Neurology after previously serving as Acting Co-Chair.

The technology, which features a unique graphene and gold-based platform and high-tech imaging, monitors the fate of stem cells by detecting genetic material (RNA) involved in turning such cells into brain cells (neurons), according to a study in the journal Nano Letters.
In a study using non-invasive tape strips in young children with eczema (or atopic dermatitis), researchers found many molecular signs of immune dysfunction and skin changes that relate to disease activity. These signs (or biomarkers) were present even before eczema was visible and can be used to track disease activity over time. With more research, these biomarkers also may help predict response to medicine and development of conditions associated with eczema, such as asthma, other allergies, infections and even attention deficit hyperactivity disorder (ADHD). Findings were published in JAMA Dermatology.
