Scientists have identified how a bacteria in the gut can act as a protective species against Salmonella infection. A team at ...

Combining a serum-free medium with a xeno-free serum replacement creates a reliable system for generating functional dendritic cells and macrophages. From foundational technologies to cutting-edge ...

Researchers use human microbiota-associated (HMA) mice to test how altered gut microbes contribute to diseases. HMA mice are germ-free strains in which human gut microbiota are established through ...

Discover how groundbreaking research reveals that gut microbes and probiotics could revolutionize anxiety relief and mental ...

Young germ-free mice transplanted with the microbes of aged mice also experienced higher inflammatory signaling and increased ...

Researchers led by Jameson observed that mice raised without any gut bacteria, known as germ-free mice, exhibited significantly lower activity in their vagus nerve compared to mice with a normal ...

Chronology of mouse germ cell development and the main epigenetic events that occur. PGCs (primordial germ cells) first emerge at embryonic day 7.25 (E7.25) as a cluster of about twenty cells.

For this study, Le and his team used a model of germ-free C57BL/6 mice — mice that have had their gut microbiomes removed — to study a potential link between gut microbes and anxiety.

To better understand the role of microbes in this process, the researchers introduced live microbes into germ-free mice. This reduced the elevated neuronal activity in the basolateral amygdala and ...
