The androgen receptor (AR), also known as NR3C4 (nuclear receptor subfamily 3, group C, member 4), is a type of nuclear receptor that is activated by binding any of the androgenic hormones, including testosterone and dihydrotestosterone in the cytoplasm and then translocating into the nucleus. 3D cartoon model with the differently colored elements of the secondary structure, white background.

$The angiotensin converting enzyme 2 (ACE2, blue) in complex with the amino acid transporter BOAT 1 (violet). ACE2 is involved in control of blood pressure and is the target for the SARS-CoV-2 virus to infect human cells..\$

The protein responsible for Alzheimer's disease has recently been identified. It has been suggested that plaques formed by amyloid-β sheets may interfere with transmission at neuronal synapses. This image uses images of the plaques and the atrophied brain caused by Alzheimer's disease as a backdrop to illustrate the horror of the disease and the realistic phenomenon in vivo.
