With the threat of multidrug-resistant bacterial pathogens growing, new ideas to treat infections are sorely needed. Researchers at University of California, San Diego School of Medicine and Skaggs School of Pharmacy and Pharmaceutical Sciences report preliminary success testing an entirely novel approach — tagging bacteria with a molecular “homing beacon” that attracts pre-existing antibodies to attack the pathogens.

Urinary tract infections (UTIs) are common, and widespread antibiotic resistance has led to urgent calls for new ways to combat them. Researchers at University of California, San Diego School of Medicine and Skaggs School of Pharmacy and Pharmaceutical Sciences report that an experimental drug that stabilizes a protein called HIF-1alpha protects human bladder cells and mice against a major UTI pathogen. The drug might eventually provide a therapeutic alternative or complement to standard antibiotic treatment.

Researchers at University of California, San Diego School of Medicine report a previously unappreciated phenomenon in which the location of injury to a neuron’s communication wire in the spinal cord — the axon — determines whether the neuron simply stabilizes or attempts to regenerate. The study, published April 30 by Neuron, demonstrates how advances in live-imaging techniques are revealing new insights into the body’s ability to respond to spinal cord injuries.

Researchers at the University of California, San Diego School of Medicine report that blocking or removing immune-suppressing cells allows a special type of chemotherapy — and the immune cells it activates — to destroy prostate tumors. This novel combination therapy, termed chemoimmunotherapy, achieved near complete remission in mouse models of advanced prostate cancer. The study is published April 29 in Nature.

Researchers at the University of California, San Diego School of Medicine and Moores Cancer Center have discovered a molecular mechanism that connects breast tissue stiffness to tumor metastasis and poor prognosis. The study may inspire new approaches to predicting patient outcomes and halting tumor metastasis.

About one quarter of all atrial fibrillation patients at the lowest risk for stroke receive unnecessary blood thinners from cardiology specialists, according to a new study by researchers at University of California, San Diego School of Medicine and University of California, San Francisco, and these health care providers must be made aware of the resulting potential health risks. The findings are published online April 13 by JAMA Internal Medicine.

We age in part thanks to “friendly fire” from the immune system — inflammation and chemically active molecules called reactive oxygen species that help fight infection, but also wreak molecular havoc, contributing to frailty, disability and disease. The CD33rSiglec family of proteins are known to help protect our cells from becoming inflammatory collateral damage, prompting researchers at the University of California, San Diego School of Medicine to ask whether CD33rSiglecs might help mammals live longer, too.

Methicillin-resistant Staphylococcus aureus (MRSA), an antibiotic-resistant superbug, can cause life-threatening skin, bloodstream and surgical site infections or pneumonia. Researchers at the University of California, San Diego School of Medicine now report that cigarette smoke may make matters worse. The study, published March 30 by Infection and Immunity, shows that MRSA bacteria exposed to cigarette smoke become even more resistant to killing by the immune system.
