Sociability in monkeys associated with higher abundance of beneficial gut bacteria

Social connections are essential for good health and wellbeing in social animals, such as ourselves and other primates. There is also increasing evidence that the gut microbiome – through the so-called 'gut-brain axis' – plays a key role in our physical and mental health and that bacteria can be transmitted socially, for example through touch.

Study illuminates how a typical gut bacterium spreads through the body

A typical gut bacterium that can spread through the body and cause a serious infection resists natural immune defenses and antibiotics by enhancing its protective outer layer, known as the cell envelope, according to a new study by Weill Cornell Medicine investigators.

COVID-19 vaccination provides higher concentrations of antibodies to babies and pregnant people

Pregnant people who received one of the mRNA COVID-19 vaccines had 10-fold higher antibody concentrations than those who were naturally infected with SARS-CoV-2, a finding that was also observed in their babies, according to a new study by researchers at Children's Hospital of Philadelphia and the University of Pennsylvania.

Novel platform allowing universal off-the-shelf T and NK cell access shows potential for immunotherapies

Recent advances in immunotherapy for cancer have stimulated a plethora of studies aimed at developing T cells (white blood cells) and Natural Killer (NK) cells (immune cells with enzymes that can kill tumor cells or cells infected with a virus) in-vitro from pluripotent stem cells - cells that are able to self-renew by dividing and developing into the three primary groups of cells that make up a human body.

Researchers shed light on the key functions of innate immune cells

Inflammation and increased mucus production are typical symptoms of worm infections and allergies. This immune response involves our innate immune cells, but their exact functions are not yet fully understood.

SARS-CoV-2 can disrupt normal mix of gut bacteria to increase risk for other infections

Infection with the pandemic virus, SARS-CoV-2, can reduce the number of bacterial species in a patient's gut, with the lesser diversity creating space for dangerous microbes to thrive, a new study finds.

Hybrid virus particles formed from coinfections exhibit immune evasion and expanded tropism

Researchers examined virus-virus interactions using human lung cells coinfected with two co-circulating respiratory infection-causing viruses, respiratory syncytial virus (RSV) and influenza A virus (IAV).

Discovery of small molecule enzyme inhibitor could be the key to treating cancers, autoimmune diseases

Researchers at the University of Illinois Chicago have found a small molecule capable of manipulating an immune process that plays an important role in cancers and autoimmune diseases.

Study reveals how SARS-CoV-2 infection of macrophages promotes inflammatory responses

Dysregulation of macrophages during SARS-CoV-2 infection and the over-exuberant production of pro-inflammatory cytokines by these macrophages has been hypothesized to contribute to severity of COVID-19 disease.

New diagnostic method applies machine learning to advanced genomics data to detect sepsis

Sepsis, the overreaction of the immune system in response to an infection, causes an estimated 20% of deaths globally and as many as 20 to 50% of U.S. hospital deaths each year.

Antibodies can prevent surface proteins of bacteria from entering host cells

Using bacteria of the Bartonella henselae species, researchers from Goethe University, Frankfurt University Hospital, the Paul Ehrlich Federal Institute for Vaccines and Biomedicines in Langen, and the University of Oslo demonstrated for the first time that antibodies can prevent certain surface proteins of bacterial pathogens from entering host cells.
