In this 3-D animation, oriented to the general public, we can see the process of histamine release by mast cell starting from the exposure to the allergen: This image shows the same process: H1 blockers are a class of widely prescribed drugs, here an excerpt of its pharmacodynamics (Source: Katzung’s Basic and Clinical Pharmacology) A….
P-glycoprotein: animation showing its role in chemotherapy resistance
Some introductory information about MDR1, the protein that mediates resistance to chemotherapeutic agents, from Wikipedia: P-glycoprotein (plasma gycoprotein, abbreviated as P-gp or Pgp) is a well-characterized ABC-transporter of the MDR/TAP subfamily. P-gp is also called ABCB1, ATP-binding cassette sub-family B member 1, MDR1, and PGY1. P-glycoprotein has also recently been designated CD243 (cluster of differentiation 243)….
Video animation: mechanism of ionotropic receptors or ligand-gated ion channels (LGICs)
In pharmacology, receptors can be divided into 4 general groups: 1. Ion channels: Ligand gatedace Voltage gated Second messenger regulated 2. G protein coupled receptors 3. Receptor tyrosine kinase 4. Intracellular hormone receptors: like the glucocorticoid receptor The video animation below shows the activation of a ionotropic receptor or ligand-gated ion channel (LGIC): An excerpt…

Proton pump inhibitors (PPIs) mechanism of action. A video animation
Mechanism of action of PPI’s. Source: Wikipedia Proton pump inhibitors act by irreversibly blocking the hydrogen/potassium adenosine triphosphatase enzyme system (the H+/K+ ATPase, or more commonly just gastric proton pump) of the gastric parietal cell. The proton pump is the terminal stage in gastric acid secretion, being directly responsible for secreting H+ ions into the…
