Role of AMP-activated protein kinase (AMPK) in carbohydrate and fat metabolism. AMPK is activated by elevated [AMP] or decreased [ATP], by exercise, by the sympathetic nervous system (SNS), or by peptide hormones produced in adipose tissue. When activated, AMPK phosphorylates target proteins and shifts metabolism in a variety of tissues away from energy-consuming processes such as the synthesis of glycogen, fatty acids, and
cholesterol; shifts metabolism in extrahepatic tissues to the use of fatty acids as a fuel; and triggers gluconeogenesis in the liver to provide glucose for the brain. In the hypothalamus, AMPK stimulates feeding behavior to provide more dietary fuel.

*Sperm fertilizing an egg* by medical animation studio

Studies have shown that it’s not the quickest nor strongest sperm that wins the race. The egg chooses who she lets in based on certain chemical connections.
Once inside, the outer shell seals up - stopping others from entering as the head of the sperm unites with the nucleus of the egg. Within days a single cell will multiply, and keep multiplying to eventually form an embryo.

This video shows the actin protein filaments (purple) and microtubules (gold) that make up the cytoskeleton of a human epithelial breast cancer cell, taken using spinning disk confocal microscopy magnified at 60x.
​
​Since the cytoskeleton is important to how the cell moves and divides, close studies of the cytoskeleton such as this can help us understand these processes.
​
​Plus, it looks utterly baller. This video was recently a runner up in the Green Fluorescent Protein Image and Video Contest run by the The American Society for Cell Biology.

A Neuron is a nerve cell. This is the basic structure of a typical Neuron.
The round nucleus contains the cell’s genetic material. The nucleus-containing central part of a neuron excluding the axons and dendrites is the cell body. The dendrites receive information in the form of electrical impulses while the axons take information away from the cell body. The Schwann cells form the Myelin Sheath around a neuron’s axon and the gaps are called nodes of Ranvier.

Macrophages have a massive spread throughout the body. Immature macrophages in the bloodstream are also called monocytes. Monocytes typically make up about 5% of the population of leukocytes. Adult macrophages in the histocytic connective tissue and those that cover the walls of the liver sinusoid are also known as Coplex cells. The macrophages in the microglia of the brain and finally those in the lungs are called alveolar macrophages. A large number of macrophages reside in the spleen, bone marrow and lymph nodes. Regardless of the name and location, all of these cells are macrophages and are part of the phagocytic system of monocots.
New studies show that macrophages are essential for heartbeat. This makes macrophages a good target for treating diseases like arrhythmias. Studies in mice lacking macrophage showed that in these animals, the electrical rhythm of the heart was abnormal.
The researchers found that macrophages in the atrioventricular node or AV node are abundant in mice and humans. This node also contains muscle cells that can transmit the contraction signal.
When they cultured the heart muscle cells and macrophages in the dish, they found that these two types of cells were physically related and simultaneously electrically stimulated. Due to these interactions, macrophages facilitated the initiation of adjacent muscle cells.

Louse got your tongue? If you’re a fish, it just might. The tongue-eating louse (Cymothoa exigua) is a rather vile critter—this parasitic crustacean likely enters a fish’s body through the gills as a juvenile, and then latches on to the tongue. From there, the louse will slowly suck all of the blood from the fish’s tongue, eventually causing it to atrophy, or wither away. The next step? The louse doesn’t kill the fish, but instead makes itself the fish’s new tongue by attaching to the stub of what was once there. It may even mate with other louses while inside the fish!
