New biomarker helps identify biological age

Once considered to be incompetent in encoding proteins due to their simple monotonous DNA repetitions, tiny telomeres at the tips of human chromosomes now appear to have a powerful biological function that could help better understand cancer and aging.

High diversity in T-cell receptor genes explains diverse response to infections

Researchers from Karolinska Institutet have demonstrated that the genes that encode the T cell receptors change significantly between individuals and communities, which could help explain why people react differently to certain diseases.

Blastocystis can promote or disrupt gut health, study finds

The gut microbiota contains trillions of bacteria that can promote health or cause disease under different conditions.

Tissue inflammation altered by “natural killer” immune cells

The discovery of a previously unknown role of “natural killer” (NK) immune cells by Melbourne researchers has increased the current understanding of how the immune system is controlled to prevent disease.

Analyzing the evolution of model organisms

A model organism used in laboratories for the past 100 years has evolved so extensively that it may no longer be fit for purpose.

Protein that facilitates cancer-causing viruses dodge the immune system

Numerous cancers have been related to the viruses Epstein-Barr virus (EBV) and Kaposi sarcoma-associated herpesvirus (KSHV). For the first time, UNC School of Medicine researchers have shown that these viruses elude the innate immune response by using a human protein called barrier-to-autointegration factor 1, or BAF, which enables the viruses to propagate and cause disease.

Researchers decipher how common environmental bacterium can digest complex waste

A common environmental bacterium, Comamonas testosteroni, could someday become nature's plastic recycling center.

Chemosynthesis fuels ocean microbes in the darkest depths

A world first study reverses the idea that the bulk of life in the ocean is fuelled by photosynthesis via sunshine, revealing that many ocean microbes in fact get their energy from hydrogen and carbon monoxide.

Countering climate change with nanowires produced by bacteria

Rapid climate change poses a serious and immediate threat to life on Earth. As atmospheric methane traps heat 30 times more effectively than CO2, temperatures are rising as a result.

UNC research describes another layer to the challenge of HIV latency

When people living with HIV take antiviral therapy (ART), their viral loads are driven so low that a standard blood test cannot detect the virus.

Study sheds new light on a lifestyle switch that occurs in marine bacteria

Scientists have detailed a lifestyle switch that occurs in marine bacteria, where they change from coexisting with algae hosts in a mutually beneficial interaction to suddenly killing them.

New genetic condition that raises vulnerability to opportunistic infections

An international consortium co-led by Vanderbilt University Medical Center immunogeneticist Rubén Martínez-Barricarte, PhD, has discovered a new genetic disorder that causes immunodeficiency and profound susceptibility to opportunistic infections including life-threatening fungal pneumonia.
