Skin microbes do more than coexist—they shape immune responses, repair tissue, and influence gene expression across your ...

In other words, these regulatory mechanisms control gene expression. But why is this control necessary? To better understand the answer to this question, consider the example of a skin cell and a ...

Scientists are exploring how gene expression patterns and their timing regulate cell differentiation. Today, researchers understand that the specialized, differentiated cell types of the adult ...

where they produce collagen and other matrix proteins that strengthen the skin barrier. The discovery broadens understanding of the immune system and may lead to new strategies for treating skin ...
