Study finds altered gut bacteria in people with early signs of Alzheimer's disease

People in the earliest stage of Alzheimer's disease -; after brain changes have begun but before cognitive symptoms become apparent -; harbor an assortment of bacteria in their intestines that differs from the gut bacteria of healthy people, according to a study by researchers at Washington University School of Medicine in St. Louis.

Vaginal seeding engrafts maternal bacteria in the bodies of cesarean section born neonates

Newborns delivered by cesarean section who are swabbed with the vaginal fluid of their mothers after birth have beneficial bacteria restored to their skin surface and stools, according to a new study.

Using ultrasound for an effective sonodynamic treatment of orthotopic pancreatic cancer

Ultrasound is a promising technique for treating cancer. Unlike laser light, used in photodynamic cancer therapy, ultrasound waves can reach deep into tissue-;up to 12 cm-;to treat deep tumors without damaging healthy cells.

Stronger defense: symptomatic malaria provides durable protection against reinfection

Researchers evaluated the immune protection conferred by symptomatic and asymptomatic P. falciparum.

Scientists show how pregnancy induces progressive changes in the maternal immune system

We have a good understanding of how a woman's external features can change during pregnancy, but scientists know surprisingly little about what biological changes occur internally.

CHOP researchers engineer stable, universal MHC-I molecules in a shorter timeframe

Class I major histocompatibility complex (MHC-I) proteins play an essential role in the immune system of all jawed vertebrates. The MHC-I displays peptide fragments of proteins from within the cell on the cell surface, "presenting" them to the immune system, which is constantly scanning the body for foreign or toxic antigens.

Immune resilience promotes longevity and resistance to infections

Researchers from The University of Texas Health Science Center at San Antonio, working with collaborators in five countries, today revealed that the capacity to resist or recover from infections and other sources of inflammatory stress -; called "immune resilience" -; differs widely among individuals.

Maximizing the function and potential of stem cell-based treatments for patients with Type 1 diabetes

Following encouraging results from pre-clinical research and a recent clinical trial on stem cell-based treatments for patients with Type 1 diabetes, researchers are now working on maximizing the function and potential of stem cell-based treatments for future application in patients.

Study illuminates how T cells fight and remember infections

The immune system protects the body from invaders, such as bacteria, viruses, or tumors, with its intricate network of proteins, cells, and organs.

Study provides a new and promising strategy for future cancer immunotherapies

CD8+ T cells, a vital component of the immune system that provides immunity against cancer, have been the focal point of anti-cancer therapies.

Sleep-disordered breathing more prevalent among short-snouted dogs, study reveals

University of Helsinki researchers tested a new method of diagnosing sleep-disordered breathing in dogs using a neckband developed for human sleep apnoea diagnostics.

Sex differences contribute to age-related inflammation: Study

Older female mice had more immune cells entering areas of the body where they shouldn't according to a new study, demonstrating that sex differences contribute to age-related inflammation that needs to be considered in future research.

Study reveals biologically validated imaging-based evidence of medically induced myelin repair

A decade after UC San Francisco scientists identified an over-the-counter antihistamine as a treatment for multiple sclerosis, researchers have developed an approach to measure the drug's effectiveness in repairing the brain, making it possible to also assess future therapies for the devastating disorder.

Antiretroviral treatment efficiently suppresses penile HIV replication

Of the 38 million people worldwide living with HIV, approximately 700,000 are newly infected men, primarily via sexual transmission.

Manipulating white blood cells to eliminate solid tumors

By silencing the molecular pathway that prevents macrophages from attacking our own cells, Penn Engineers have manipulated these white blood cells to eliminate solid tumors.

New cell culture model generates the alveolar macrophage in the lab

Researchers at Texas Biomedical Research Institute have succeeded in generating the lung's most important immune cell, the alveolar macrophage, in the lab.

Study suggests the role of histamine-releasing factor in severe asthma and RV-induced asthma exacerbation

Asthma is more dangerous than many people realize. An estimated 10 Americans die everyday from asthma, and the disease leads to around 439,000 hospitalizations and 1.3 million emergency room trips each year.

Researchers identify a potential breakthrough in glioblastoma treatment

In a recently published manuscript, Howard Colman, MD, PhD, Jon M. Huntsman Presidential Professor of Neuro-Oncology and co-leader of the Neurologic Cancers Disease Center and the Experimental Therapeutics CCSG program at Huntsman Cancer Institute, identified a potential breakthrough in glioblastoma treatment.

Study raises new hopes for blood cancer patients with an incomplete response to CAR T cell therapy

The aim of immunotherapy strategies is to use cells in the patient's own immune system to destroy tumor cells. CAR T cell therapy is an immunotherapy that is effective in treating blood cancer.

Researchers identify microRNAs associated with a weakened immune response to COVID-19

A team of researchers at NYU Abu Dhabi, led by Associate Professor of Biology Youssef Idaghdour and working in collaboration with clinicians at several Abu Dhabi hospitals, investigated the association between microRNAs, a class of small RNA molecules that regulate genes, and COVID-19 severity among 259 unvaccinated COVID-19 patients living in Abu Dhabi.
