Blastomycosis is a fungal infection caused by inhaling Blastomyces dermatitidis spores. If it involves only the lungs, it is called pulmonary blastomycosis. Only about half of people with the disease have symptoms, which can include fever, cough, night sweats, muscle pains, weight loss, chest pain, and feeling tired.

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.\

This illustration demonstrates the molecular level of protection that DNA provides by surrounding the human figure and resisting viruses such as the coronavirus. We see the double helix of DNA wrapped around the body, creating a protective barrier against invading viral particles. Coronavirus particles, depicted with spikes, symbolize the threat that DNA successfully counteracts by repelling them and preventing them from entering cells. This visualization is ideal for medical, educational, and scientific materials covering immunity, genetics, and biodefense.

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.
