Immune cells hold clues to vitamin D absorption, study suggests

Vitamin D plays an integral role in regulating immune function, and Penn State researchers have identified immune cells in mice that can be differentiated by whether or not they have vitamin D receptors—a finding that could ...

Study shows immune cells have a backup mechanism

The enzyme TBK1 is an important component of the innate immune system that plays a critical role in the defense against viruses. Upon mutation-induced loss of TBK1 function, patients show an increased susceptibility to viral ...

Exploring how fungal spores hijack lung cells

The pathogenic fungus Aspergillus fumigatus escapes elimination from surface cells of the human lung by binding to a human protein. In doing so, it is able to nest in so called phagosomes, confined areas in the lung cells, ...

How bacteria invade the brain

A new study led by researchers at Harvard Medical School details the step-by-step cascade that allows bacteria to break through the brain's protective layers—the meninges—and cause brain infection, or meningitis, a highly ...
