3d rendering of Bacteria are coated with an extra self-assembled lipid membrane to improve their survival against environmental assaults.
The calcitonin gene related peptide (yellow) binds to its receptor (blue) on neurons and smooth muscle cells of cerebral blood vessels, activating a signal cascade through G-proteins (dark blue) in this cells that  leads to a dilatation of the blood vessels (vasodilatation). Blocking the CGRP receptor diminishes the quantity of migraine attacks.\

Photomicrograph of filamentous blue-green algae, Oscillatoria species. Each band along the stand is one cell. This filament is very short probably having recently parted from a longer one. Filaments are typically many times longer. This algae is mobile, it moves and twists through the water. San Francisco Bay, California, USA. Live specimen. Wet mount, 40X objective, transmitted brightfield illumination. Note - motion blur of live specimen, very shallow depth of field, chromatic aberration and uneven focus are inherent in light microscopy.

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.
