The immune system is comprised of two separate active arms of immunity to provide robust protection against disease. The two separate systems of immunity include the innate and adaptive immune ...

The immune cell repertoire is composed of many different cell types that are orchestrated in response to infection and other pathogens that enter the body. As a result, the body can defend itself ...

Researchers have developed a way to grow a highly specialized subset of brain nerve cells that are involved in motor neuron disease and damaged in spinal injuries. Their study, published today in ...

A new method developed by Penn State biologists allows them to turn stripped-down plant cells into other types of cells, ...

Discover how specialized cells form immune-boosting niches in lung tumors, unlocking new strategies to enhance cancer treatments and improve outcomes. Study: Fibroblastic reticular cells generate ...

The human small intestine absorbs nutrients while protecting us from potentially harmful microbes. One of the cell types that plays a key role in this protection is the microfold cell (M cell). These ...

The body regulates its metabolism precisely and continuously, with specialised cells in the pancreas constantly monitoring the amount of sugar in the blood, for example. When this blood sugar level ...

A progenitor-derived corticospinal-like neuron in cell culture, extending its long axon, even in isolation. The cell body (or "soma"; immunolabeled by Tuj1 antibody in red) is at the top, with the ...

Banding patterns of cellulose increase the stability of plant cell walls, much like the corrugated patterns in cardboard. Penn State biologists developed a method to isolate plant cells and observe ...
