The early-life intestinal microbiota plays a key role in shaping host immune system development . We found that a single early-life antibiotic course ( 1PAT ) accelerated type 1 diabetes ( T1D ) development in male NOD mice . The single course had deep and persistent effects on the intestinal microbiome , leading to al...
The human body contains many microbes that play important roles in our health . These microbes begin to live in the intestines , skin , and mouth shortly after birth . They form complex communities called the microbiome , which changes as babies develop . The microbiome works with organs to maintain human health . For ...

Synaptic up-scaling preserves motor circuit output after chronic, natural inactivity
Our visual memory percepts of whether we have encountered specific objects or scenes before are hypothesized to manifest as decrements in neural responses in inferotemporal cortex ( IT ) with stimulus repetition . To evaluate this proposal , we recorded IT neural responses as two monkeys performed a single-exposure vis...
As we go about our daily lives , we store visual memories of the objects and scenes that we encounter . This type of memory , known as visual recognition memory , can be remarkably powerful . Imagine viewing thousands of images for only a few seconds each , for example . Several days later , you will still be able to d...

The tumor suppressor PIP3 phosphatase PTEN is phosphorylated on four clustered Ser/Thr on its C-terminal tail ( aa 380–385 ) and these phosphorylations are proposed to induce a reduction in PTEN’s plasma membrane recruitment . How these phosphorylations affect the structure and enzymatic function of PTEN is poorly unde...
PTEN is an enzyme that is found in almost every tissue in the body , and its job is to stop cells dividing . If it fails to perform this job , the uncontrolled proliferation of cells can lead to the growth of tumors . PTEN stops cells dividing by localizing at the plasma membrane of a cell and removing a phosphate grou...
