A small primer on the #NobelPrize awarded to Mary E. Brunkow, Fred Ramsdell and Shimon Sakaguchi today. This prize was for combining two separate fields of immunology research - genetic research on IPEX and immunology research of regulatory T cells (#Tregs), with enormous impact on biology/medicine

We introduce the concept of the "podosome base", a region of plasma membrane-associated podosome components.

Myo1e (green) shows a more ventral localization than the F-actin core (red) of podosomes. XZ side view of two podosomes.
