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.
3D Rendered Illustration, visualization of Neurons firing neurotransmitters in the synaptic gap.
The glucagon like peptide-1 receptor (GLPr) is a G proteincoupled receptor (GPCR) that mediates the action of GLP-1, a peptide hormone. The activated receptor  has a strong effect  on the management of type 2 diabetes mellitus and obesity, including glucose homeostasis and regulation of gastric motility and food intake.

graphs and cells
Epidermal growth factor (EGF) activates the EGF receptor (EGFR), that builds a heterodimer with HER3.  The signal transduction continues through GRB2/SOS, Ras,  Raf/MEK and ERK, that will activate many processes in the cell. Dysregulation is linked to cancer progression

The thyroid hormone receptor is a type of nuclear receptor that is activated by binding thyroid hormone. TRs act as transcription factors, ultimately affecting the regulation of gene transcription and translation. 3D cartoon model, black background.
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.
Rhodopsin is a light sensitive G-protein coupled receptor with retinal (red) as cofactor.  that stimulates the G-protein transducin (blue), which releases GDP and binds GTP (yellow) resulting in the liberation of its  subunit (light blue).  Source: PDB entry 6oy9
Computer generated 3D abstract forms.\n\nNote: This image is less than one year old, and is  not available for use anywhere else. I created it on Blender 3.0.1,  and that is the reason it has no EXIF data. I uploaded in a property release section a screenshot of processing the composition on Blender on my PC. Date of creation is 01/11/2022.
