Examples
“Alzheimer's is marked by deposits of beta-amyloid protein in the brain, and knotty protein structures in the nerves themselves called tau tangles.”
“Eventually another small protein, called tau, also starts to crystallize in this way to form "tangles.”
The Wall Street Journal: Connecting the Pieces of the Alzheimer's Puzzle
“Among the possible advances in early detection are chemical tracers, some of which tag clumps of a sticky substance in the brain called amyloid, and others that mark amyloid and a protein called tau—both thought to contribute to the disease.”
“The crucial protein, called a tau protein, is a normal part of the brain and central nervous system.”
New Hope For Early Diagnosis And Treatment Of Alzheimer’s | Impact Lab
“The first one, the electron, was discovered in 1897, and the last one, this thing called the tau neutrino, in the year 2000.”
“We discovered that these fibers are made of a protein called tau and then we discovered that we could pull these fibers apart.”
“This process, called tau phosphorylation, enables the microtubules to unbind and then bind again, allowing brain cells to connect and reconnect with other brain cells.”

“Martin Perl's discovery of the tau was the first sign that a third "family" of fundamental building blocks existed.”
“The new lepton was denoted by the Greek letter tau, which is the first letter of the word triton, (which means the third); the discovered lepton being the third charged lepton, after the electron and the muon.”
