Researchers reveal key differences in STING inhibition between humans and miceResearchers have long focused on the STING (Stimulator of Interferon Genes) pathway as a way to harness the immune system's natural defenses against cancer. This pathway, which plays a key role in helping the body defend against potential pathogens, can be leveraged to trigger an innate immune response that targets... Read more

Study finds overtraining syndrome tied to increased PARP1 protein in musclesExcessive physical exercise, especially without adequate rest, can damage the human body in various ways. In severe cases, it can progress to overtraining syndrome, which is characterized by decreased performance and appetite, chronic fatigue, muscle pain, increased injuries, and changes in the immune system and metabolism....

Preclinical study unlocks a mystery of rapid mouth healingBite the inside of your cheek, and the wound may vanish without a trace in a couple of days. A preclinical study co-led by Cedars-Sinai, Stanford Medicine and the University of California, San Francisco (UCSF), has discovered one secret of this disappearing act. The findings, if confirmed in humans, could... Read more

Using viral load tests to help predict mpox severity when skin lesions first appearIn August 2024, the World Health Organization declared a second "Public Health Emergency of International Concern" for mpox. The current outbreak in Africa is driven mainly by the clade I variant, with multiple countries reporting their first-ever mpox cases of this more severe strain.... Read more

Antifungal discovery offers hope against deadly drug-resistant infectionsCandida auris is a dangerous fungal pathogen that has become a global health concern. It spreads easily in health care settings and can cause life-threatening infections, especially in patients with weakened immune systems. Alarmingly, it is often resistant to multiple antifungal drugs, making treatment difficult.... Read more

Benzaldehyde blocks pancreatic cancer spread by disrupting key protein interactionsCancer cells have the capacity to multiply rapidly. The aggressive cancer cells undergo conversion from their tightly connected epithelial state into a mesenchymal state, which lacks contact restrictions and spreads easily to other parts of the body. Such epithelial-to-mesenchymal plasticity also makes the cancer cells resistant to elimination by anticancer... Read more

Rare lung cells trigger rapid repair after smoke or virus exposure in mice—a similar pathway may exist in humansA rare cell in the lining of lungs is fundamental to the organ-wide response necessary to repair damage from toxins like those in wildfire smoke or respiratory viruses, Stanford Medicine researchers and their colleagues have found. A similar process occurs in the pancreas, where the cells, called neuroendocrine cells, initiate... Read more

How modified RNA tricks the innate immune systemThe innate immune system is the body's first line of defense against pathogens and foreign substances. An essential component of this system are pattern recognition receptors, which recognize non-self RNA—such as that from viruses and bacteria—and trigger an immune response.... Read more
