New collaboration may lead to future clinical trials to test treatment for leukemia

In a new pre-clinical study published this week in the journal Leukemia, the research team of Children's Hospital Los Angeles investigator Hisham Abdel-Azim, MD, MS, worked with colleagues to engineer T-cells to identify and target multiple sites on acute lymphoblastic leukemia cells instead of just one. The early collaboration points the way to future clinical trials to test the therapy.

Study reveals how hormone leptin contributes to weight loss

Some call it baby fat. But recent research has shown that adults have it too--which is a good thing. Brown fat, the so-called good fat that can protect against obesity and associated health risks, like cardiovascular disease and diabetes, is located in small pockets throughout the body.

Study provides insights into pain signaling mechanism in the brain

Fast communication between our brain cells - or neurotransmission as it is called - is hugely important for our brain to work properly. Some of the messengers involved in this form of communication are neuropeptides, which are chemicals produced in the brain.

Researchers discover new biomarker for early detection of Alzheimer's disease

Researchers at the University of California San Diego discovered that high blood levels of RNA produced by the PHGDH gene could serve as a biomarker for early detection of Alzheimer's disease.

Individuals taking glucocorticoids are at high risk if infected with COVID-19

Individuals taking a class of steroid hormones called glucocorticoids for conditions such as asthma, allergies and arthritis on a routine basis may be unable to mount a normal stress response and are at high risk if they are infected with the virus causing COVID-19, according to a new editorial published in the Endocrine Society's Journal of Clinical Endocrinology & Metabolism.

Fracking chemical may interfere with reproductive hormones in men

A chemical used in hydraulic fracturing, commonly called fracking, has the potential to interfere with reproductive hormones in men, according to research accepted for presentation at ENDO 2020, the Endocrine Society's annual meeting, and publication in a special supplemental section of the Journal of the Endocrine Society.
