Bisphenol A In Food Containers Has Adverse Effect On Brain Tissue

...studies also paved the way to understand the rapid signaling mechanism of estrogen in regions of the brain that were previously thought not to be involved in sexual differences. Bisphenol A (BPA) is used as an artificial estrogen and is the primary hormone in female sexual development, but low doses of BPA b...

Multiple Sclerosis Can Be Treated By Blocking Fat Hormone

...The authors delved further to unravel the cellular signaling events underlying these beneficial effects. Taken together, the data provides a basis for the development and testing of novel strategies of leptin-based targeting for the potential treatment of MS. Edited (ANI)...

TNF Helps in the Understanding of the Immune System and Development of Drugs against Various Ills

...ed by redness, swelling and pain. This cellular signaling system of the TNF molecule is a very weak radio transmitter. It moves very slowly and is unable to send that message over long distances. But Levchenko said that the cellular pathways that pick up this signal act like extremely sensitive radio receiv...

Understanding Basic Motor Skills

...PICK1 controls the Purkinje cell's response to the signaling molecule, glutamate. The Purkinje cells swallow up surface proteins called AMPA receptors. Without AMPA receptors on the surface, these cells cannot respond to signals from neighboring neurons. Researchers now know how PICK1 are involved in the sw...
