Link between gut dysbiosis and chronic diseases explored in new study

Study explores the ecological causes of gut dysbiosis and its link to human diseases, revealing how imbalances in gut microbiota composition, influenced by host-derived factors like oxygen and nitrate, contribute to various chronic conditions.

IU researchers uncover novel mechanism of pathogen entry into cells

Similar to a burglar breaking a window to get into a house, Indiana University researchers have discovered a previously unknown process by which pathogens enter a cell with physical force, breaching the body's immune defenses that prevent infection.

Lizards' ability to regenerate cartilage could lead to new treatments for osteoarthritis

A team of researchers from the Keck School of Medicine of USC have published the first detailed description of the interplay between two cell types that allow lizards to regenerate their tails.

Childhood abuse can induce stress that changes neural networks and functions during growth

Childhood neglect and/or abuse can induce extreme stress that significantly changes neural networks and functions during growth. This can lead to mental illnesses, including depression and schizophrenia, but the exact mechanism and means to control it were yet to be discovered.

Candida auris escapes innate immunity through metabolic reprogramming

A team of scientists from Australia and Israel demonstrates that Candida auris, a fungus associated with life-threatening and drug-resistant infections, escapes the host's innate immune response by destroying macrophages through metabolic reprogramming. The fungus is also capable of escaping antimicrobial inflammatory response.

Underlying genetic cause for MIS-C complications after COVID-19 identified

A recent Science journal study determined the underlying cause of MIS-C related to SARS-CoV-2 in some children. It hypothesized that monogenic inborn errors of immunity (IEI) is the primary reason for this condition. Identifying these inborn errors is expected to help elucidate the disease's cellular, molecular, and immunological basis.

A hybrid, multiscale, individual-based model to study the within-host spread of SARS-CoV-2 and the subsequent innate immune response

In this study, the authors have specifically studied the interactions of epithelial cells, a subset of cytokines and macrophages.

Study may lead to new therapies that accelerate removal of cellular debris from the brain

Microglia -- the brain's immune cells -- play a primary role in removing cellular debris from the brain. According to a recent study by a Nagoya University-led research team in Japan, another kind of brain cell, called astrocyte, is also involved in removing debris as a backup to microglia.

Groundbreaking technology could enhance therapeutic efficiency of nanomedicines

Researchers from the Moscow Institute of Physics and Technology and their colleagues from Shemyakin-Ovchinnikov Institute of Bioorganic Chemistry and Prokhorov General Physics Institute of the Russian Academy of Sciences have developed a breakthrough technology to resolve a key problem that has prevented the introduction of novel drugs into clinical practice for decades.

Researchers develop new coatings for implants to make them more compatible

New coatings on implants could help make them more compatible. Researchers at the Martin Luther University Halle-Wittenberg (MLU) have developed a new method of applying anti-inflammatory substances to implants in order to inhibit undesirable inflammatory reactions in the body.

UVA scientists seek answers to questions about spinal cord injuries

Two top scientists at the University of Virginia School of Medicine are seeking answers to questions about spinal cord injuries that have long frustrated the development of effective treatments.

Combination therapy boosts the immune system's appetite for cancer

A combination of immunotherapy agents that encourages some immune cells to eat cancer cells and alert others to attack tumors put mice with a deadly type of brain cancer called glioblastoma into long-term remission, a new study led by UT Southwestern scientists suggests.

Attacking HIV at the source

A new study published on November 26, 2019, in the journal Cell Reports, details a new discovery that may help avert HIV infection right at the start. The virus is known to take a long time to infect a person, and the scientists say they have found a period during which it can be weakened or killed, in the very first hours after it has entered a host. They call this the window of vulnerability.

New way to thwart HIV infection at early stages

1.7 million. That's how many people are infected with the human immunodeficiency virus (HIV) each year worldwide. 1.7 million people who are condemned to lifelong antiretroviral therapy (ART) or risk developing fatal AIDS . Out of the 37.9 million people living with HIV (PLWH), 22.3 million have access to ART, allowing them to have an almost normal lifespan.

How pathogens are controlled under hypoxic conditions

Infected tissue has a low concentration of oxygen. The body's standard immune mechanisms, which rely on oxygen, can then only function to a limited extent.

Novel targeted drug delivery system improves conventional cancer treatments

A team of researchers, affiliated with UNIST has recently introduced a novel targeted drug delivery system that can improve the pharmacological and therapeutic properties of conventional cancer treatments.

Neuropeptide Y may hold key to exacerbating severe influenza

Severe influenza virus infection is characterized by a strong inflammatory response and profuse viral replication in lungs. These viruses, such as the notorious avian flu, have a high rate of death and to date there are no effective treatments.

New study shows how the immune system regulates gut fungal population

Immune cells that process food and bacterial antigens in the intestines control the intestinal population of fungi, according to a new study from Weill Cornell Medicine scientists.

Activated T-cells promote heart failure after heart attack

Chronic inflammation after a heart attack can promote heart failure and death. University of Alabama at Birmingham researchers have now shown that activated T-cells — part of the immune system's inflammatory response — are both necessary and sufficient to produce such heart failure.
